案例标题: 白龙港污水处理厂污泥处理工程实践
原文: 演讲题目:白龙港污水处理厂污泥处理工程实践 演讲者:徐月江 一、项目背景 到2008年底,上海市共有城镇污水处理厂50座,总处理能力为672.25万m3/d。2008年全市城镇污水处理厂污水处理量为481.18万m3/d ,其中中心城区污水处理量376.61万m3/d ,中心城区污水处理率达到85.8%,随着竹园一厂升级改造、白龙港污水厂扩建二期工程的建成,污水处理率还在不断提高。污泥处理处置的水平仍停留在上世纪八、九十年代,全市90%的污泥经简单的浓缩脱水后填埋处置,污泥的无害化处理仅为10%,严重滞后于污水处理水平。未经恰当处理处置的污泥进入环境后,给生态环境造成了极大隐患。 目前上海全市中心城区范围内实际污泥量约2000吨/天(含水率80%),石洞口污水处理厂目前的实际污泥处理量为430吨/天(含水率80%);按照规划,白龙港污泥处理工程的设计规模为1020吨/天(含水率80%)。 通过白龙港污泥工程的建设,上海中心城区污水厂约一半的污泥将得到处理,将有助于提高上海市污水污泥的处置能力,并切实保护黄浦江和长江的水环境。 二、工程概况 白龙港污泥工程是世界银行贷款项目,于2005年列入上海城市环境项目APL二期城市污水管理子项目,同时列入上海市三年环保行动计划,2008年12月又列入国家新增中央投资项目。 白龙港污泥处理工程是对白龙港污水处理厂200万m3/d污水处理产生的污泥进行处理,设计处理规模为268干吨污泥/日。工程建成后,白龙港污泥处理规模将在亚洲位居第一。处理工艺采用浓缩、厌氧消化、污泥脱水和部分脱水污泥干化处理工艺。 初沉污泥和剩余污泥进行浓缩和厌氧消化,消化产生的沼气经过处理后首先用于热水锅炉,热水锅炉产生的热水用于加热消化池污泥,多余的沼气将作为能源来干化脱水污泥。污泥干化处理后冷凝水的余热回用于污泥消化系统供热。干化后的污泥外运作为园林绿化介质土或填埋场覆盖土。经厌氧消化稳定的脱水污泥运至填埋场进行填埋处置。 白龙港污泥工程总投资6.8亿人民币,其中:城建资金20415万元,世行贷款为3700万美金(折合人民币28490万元),其余资金19146万元由项目单位通过国内银行贷款等方式筹措。 2008年2月,开工;预计整个污泥工程于2010年年底建设完成投入运行。 三、工程技术与亮点 1. 本工程在对国内外污泥处理处置经验总结提高的基础上,采用了能实现节能减排、循环利用的污泥处置BAT技术。污泥处理过程中产生的原声污泥通过“污泥厌氧消化+干化”的工艺处理后可用于土地利用。该工艺路线对污泥进行了稳定化、减量化、无害化处理,使之全面达到国家标准,为资源化利用创造了条件。本工程是世界上规模最大的采取同类处理工艺的污泥处理工程之一。 2. 本工程有机结合了污泥消化工艺与污泥干化工艺。消化过程产生的多余沼气利用于污泥干化,再将污泥干化时产生的冷凝水的余热用于污泥消化加热,大大降低运行成本,最大限度的实现节能减排。达到了国内首创、国际先进水平。按照设计,通过污泥消化近期可产生约4.5万m3/d的沼气量,相当于产生约1.2万kw/d的热量,估计每年可减少排放约13万吨二氧化碳。 3. 根据白龙港污水处理厂不同污水处理工艺的污泥种类、污泥特性的具体特点,结合工程实际运行需要,创造性的采用了“化学污泥和初沉污泥重力浓缩,剩余污泥重力浓缩+离心二级浓缩”的方案,做到了工程投资、运行成本、技术可靠性及运营管理的综合平衡,运行上更加灵活。 4. 在充分调研国内污水处理厂沼气处理运行情况后,充分考虑到了国内众多污水处理厂高硫化氢浓度对沼气处理系统及消化处理系统的严重负面影响,本工程对消化处理产生的沼气采用生物脱硫+干式脱硫的两级串联的沼气脱硫工艺。本工程第一次创新性的在市政污水厂采用了沼气的生物脱硫,该生物脱硫最大特点是将碱洗洗涤塔与生物反应器相结合,并且在生物反应器中形成碱性溶液。即,可以从生物反应器中回收碱,因此运行费用远较传统湿法脱硫低,而且对硫化氢的去除效果极佳。据我们以本工程数据测算,在一次性投资基本相当的情况下,每年仅运行费用较传统湿法脱硫约低120余万。该系统还一个优点是可以回收单质硫,以本项目数据测算,每天回收的纯度97%左右的硫约计数百公斤,如能找到合适的销路,也会产生一定的经济效益。 5. 工程场地为滩涂地形,地址条件差,工程在控制投资的前提下,将90%以上的工艺管线集中敷设于地下管廊及综合管沟中,既节约地下空间,又利于管线的安装、检修及维护。同时将8座蛋形消化池及其管线楼连接,形成一个完整有序的地下空间及垂直交通,利于设备、管道、电缆等的施工及运行管理。 6. 对污泥进泥系统,不采用直接将原污泥注入消化池的方式,而采用高效污泥接种器,将原污泥首先与消化池循环污泥混合后,再经过热交换器,将混合污泥加热到36-38度,再平稳地投入消化池。这样大大减少了原污泥对消化运行系统的冲击,提高了系统的效率。 7. 本项目采用35度中温厌氧消化,加热的关键设备热交换器采用外部热交换器,型式为套管式,因为此类热交换器的压力损失小,并且没有污泥板结的危险。热交换器的每个部分都装有自动除气装置,用于去除水循环中的气体。 8. 对应于蛋形消化池浮渣面小,我们在浮渣排除设备选型上,选择了速开速闭型的浮渣排放门,在有浮渣产生时,通过调整排渣液位,迅速排渣,效率很高。同时该浮渣门设备将严格保证气密性,确保系统运行的安全。 9. 出于系统安全性考虑,消化池顶各设备中日常有可能进行开盖操作的设备,如观察窗,在材料的选择上,必须防止材料接触过程中可能产生的火花,因此这部分材料我们选择的是青铜、黄铜。观察窗还装有一体式的雨刷。附属的喷射设备可以冲洗观察窗,设计考虑非常周全精细。 10. 对于消化池内产生泡沫探测及防止泡沫进入沼气管路系统的考虑,为了在有泡沫的情况下,不影响设备运行,现代化的消化池气体进口系统中安装有泡沫捕集器。该设备可以在泡沫形成到一定阶段时发出信号,并且通过喷射水墙阻止泡沫进入气体系统。本项目将沼气集气罩与泡沫消除装置设计成一体化装置,以实现沼气的顺利排出。 11. 消化池顶通常采用两种形式的过压/负压保护设备:机械型和水力型。机械型设备操作烦琐,误操作之后会失去保护效果。当消化池进行卸压和恢复运行条件时,运行会造成负面影响。设备的设计已经考虑到过压和负压的最不利情况,同时保证了安全功能的自动运行。水力安全设备失效只可能导致系统内部的压力降,而不会对设备或消化池产生损坏。特殊的设计可以保证在最冷的温度下,安全装置仍然不会结冰。 12. 另外对应每台消化池,本项目还考虑了功能强大的阀组及管路系统,通过各组阀门的调节,以实现调试、运行、应急等不同场合的需求,同时还加设一般污水厂不曾加设的备用循环污泥系统,以实现调试初期或搅拌器出现故障时期保证消化池的搅拌效果。总之,实现了整个消化系统运行方式的高度灵活性、性能可靠及操作简便。
译文: 演讲题目:白龙港污水处理厂污泥处理工程实践 演讲者:徐月江 Topic of Speech: The Sludge Disposal Engineering Practice of Bai Longgang Sewage Treatment Plant Lecturer: Yuejiang XU 一、项目背景 background of project 到2008年底,上海市共有城镇污水处理厂50座,总处理能力为672.25万m3/d。2008年全市城镇污水处理厂污水处理量为481.18万m3/d ,其中中心城区污水处理量376.61万m3/d ,中心城区污水处理率达到85.8%,随着竹园一厂升级改造、白龙港污水厂扩建二期工程的建成,污水处理率还在不断提高。污泥处理处置的水平仍停留在上世纪八、九十年代,全市90%的污泥经简单的浓缩脱水后填埋处置,污泥的无害化处理仅为10%,严重滞后于污水处理水平。未经恰当处理处置的污泥进入环境后,给生态环境造成了极大隐患。 By the end of 2008, 50 urban sewage treatment plants with a total daily capacity of 6.7225 million cubic meters have been built in Shanghai. In the year of 2008, the whole city’s capacity of sewage treatment reached 4.8118 cubic meters per day, among which the central district at 3.7661 million cubic meters with a sewage treatment rate of 85.8%. With the upgrading of Zhuyuan No.1 factory and the second phase extension project of Bai Longgang sewage treatment plant, the sewage treatment rate is raising steadily. However, the sludge disposal capacity still stays in the level of 1980s and 1990s. Through simple thickening and dewatering, 90% of the city’s sludge is treated by landfill process. The decontamination rate of the sludge disposal is 10% only, which is lagged far behind the sewage treatment capacity. The release of improper disposed sludge leads to hidden dangers to the environment. 目前上海全市中心城区范围内实际污泥量约2000吨/天(含水率80%),石洞口污水处理厂目前的实际污泥处理量为430吨/天(含水率80%);按照规划,白龙港污泥处理工程的设计规模为1020吨/天(含水率80%)。 通过白龙港污泥工程的建设,上海中心城区污水厂约一半的污泥将得到处理,将有助于提高上海市污水污泥的处置能力,并切实保护黄浦江和长江的水环境。 At present, the sludge output of central district is around 2000 tons per day (the moisture content is 80%), while the current capacity of sludge disposal in Shi Dongkou sewage treatment plant is 430 tons per day (the moisture content is 80%). According to the plan, the designed scale for Bai Longgang sludge disposal project (BSDP) is 1020 tons per day (the moisture content is 80%). Through the establishment of Bai longgang sludge disposal project, about half of the sludge in Shanghai central district will be treated properly, which is beneficial for improving the sewage and sludge capacity of the city and protecting the water environment of Huangpu River and Yangtze River. 二、工程概况 the outline of the project 白龙港污泥工程是世界银行贷款项目,于2005年列入上海城市环境项目APL二期城市污水管理子项目,同时列入上海市三年环保行动计划,2008年12月又列入国家新增中央投资项目。 BSDP as a World Band financed project was included to be a subsidiary project of Shanghai Environment Project – APL Second Phase Urban Sewage Management in 2005. In the same year, it was also listed on Shanghai three-year environmental action plan and was subsequently included in China’s new investment projects in December 2008. 白龙港污泥处理工程是对白龙港污水处理厂200万m3/d污水处理产生的污泥进行处理,设计处理规模为268干吨污泥/日。工程建成后,白龙港污泥处理规模将在亚洲位居第一。处理工艺采用浓缩、厌氧消化、污泥脱水和部分脱水污泥干化处理工艺。 BSDP is set to treat the sludge produced by sewage treatment with a total number of 2 million cubic meters per day, and the designed capacity scale is 268 tons per day. After finished, the capacity scale of BSDP will rank first in Asia. The treatment techniques used are namely thickening, anaerobic digestion, sludge dewatering, and drying of dewatered sludge. 初沉污泥和剩余污泥进行浓缩和厌氧消化,消化产生的沼气经过处理后首先用于热水锅炉,热水锅炉产生的热水用于加热消化池污泥,多余的沼气将作为能源来干化脱水污泥。污泥干化处理后冷凝水的余热回用于污泥消化系统供热。干化后的污泥外运作为园林绿化介质土或填埋场覆盖土。经厌氧消化稳定的脱水污泥运至填埋场进行填埋处置。 The raw sludge and the excess sludge are firstly processed by thickening and anaerobic digestion, and then the treated biogas get by digestion is used to heat the hot water-boiler. After that, the hot water is used to heat the sludge in the digestion tank, and the rest biogas is used as energy to dry the dewatered sludge. The waste heat of the condensation water from the drying process is back for the heating of sludge digestion system. The dried sludge is delivered as medium soil for landscaping or covering soil for waste landfill. The dewatered sludge through anaerobic digestion is treated by landfill. 白龙港污泥工程总投资6.8亿人民币,其中:城建资金20415万元,世行贷款为3700万美金(折合人民币28490万元),其余资金19146万元由项目单位通过国内银行贷款等方式筹措。 2008年2月,开工;预计整个污泥工程于2010年年底建设完成投入运行。 The total investment of BSDP is 0.68 billion yuan, among which 204.15 million yuan is raised from urban construction funds, 3.7 million US dollar (about 284.9 million yuan) is loaned from World Bank, and the rest 191.46 million yuan is collected by the project organizer through loan financing from the domestic banks. Started from February 2008, the construction of this project is estimated to complete and put into operation by the end of 2010. 三、工程技术与亮点the project technology and bright spots 1. 本工程在对国内外污泥处理处置经验总结提高的基础上,采用了能实现节能减排、循环利用的污泥处置BAT技术。污泥处理过程中产生的原声污泥通过“污泥厌氧消化+干化”的工艺处理后可用于土地利用。该工艺路线对污泥进行了稳定化、减量化、无害化处理,使之全面达到国家标准,为资源化利用创造了条件。本工程是世界上规模最大的采取同类处理工艺的污泥处理工程之一。 Based on the experience and improvement of sludge disposal around the world, this project adopts BAT technique which is able to realize energy-efficiency, emission-decreasing, and recycling. Through the process of “anaerobic digestion + drying”, the raw sludge from sludge treatment could be processed for land utilization. This technique line enables the sludge to reach the state standard by stabilization, minimization, and harmlessness processes, and creates favorable environment for resource utilization. Among the worldwide sludge disposal projects using the same type of treatment technique, this is one of the largest projects. 2. 本工程有机结合了污泥消化工艺与污泥干化工艺。消化过程产生的多余沼气利用于污泥干化,再将污泥干化时产生的冷凝水的余热用于污泥消化加热,大大降低运行成本,最大限度的实现节能减排。达到了国内首创、国际先进水平。按照设计,通过污泥消化近期可产生约4.5万m3/d的沼气量,相当于产生约1.2万kw/d的热量,估计每年可减少排放约13万吨二氧化碳。 This project combines sludge digestion technique and drying technique. The waste biogas from digestion process is used to dry sludge and the waste heat of water condensation from drying process is used to heat the sludge in digestion tank. In this way, the running cost is greatly reduced, the energy-efficiency is maximized and the emission is minimized. This technology filled in the blank of the domestic relevant application, belonged to domestic initiation and had reached the international advanced level. According to the plan, the estimated 45 thousand cubic meters biogas could be produced by sludge digestion per day, which is equivalent to around 12 thousand kilowatts heat per day, and estimated 130 thousand tons carbon emissions are hoping to reduce in this way. 3. 根据白龙港污水处理厂不同污水处理工艺的污泥种类、污泥特性的具体特点,结合工程实际运行需要,创造性的采用了“化学污泥和初沉污泥重力浓缩,剩余污泥重力浓缩+离心二级浓缩”的方案,做到了工程投资、运行成本、技术可靠性及运营管理的综合平衡,运行上更加灵活。 According to the specific characteristics of the sludge and the types of sludge in sewage treatment, an innovative process of “gravity concentration of chemical and raw sludge, excess sludge gravity concentration + second centrifugal concentration” is used with the combination of practical needs. A comprehensive balance among project investment, running cost, technical reliability, and running management is achieved with more flexible operation. 4. 在充分调研国内污水处理厂沼气处理运行情况后,充分考虑到了国内众多污水处理厂高硫化氢浓度对沼气处理系统及消化处理系统的严重负面影响,本工程对消化处理产生的沼气采用生物脱硫+干式脱硫的两级串联的沼气脱硫工艺。本工程第一次创新性的在市政污水厂采用了沼气的生物脱硫,该生物脱硫最大特点是将碱洗洗涤塔与生物反应器相结合,并且在生物反应器中形成碱性溶液。即,可以从生物反应器中回收碱,因此运行费用远较传统湿法脱硫低,而且对硫化氢的去除效果极佳。据我们以本工程数据测算,在一次性投资基本相当的情况下,每年仅运行费用较传统湿法脱硫约低120余万。该系统还一个优点是可以回收单质硫,以本项目数据测算,每天回收的纯度97%左右的硫约计数百公斤,如能找到合适的销路,也会产生一定的经济效益。 Based on the sufficient survey of biogas treatment in domestic sewage treatment plants and the full consideration of substantial negative impact of high-hydrogen sulfide in biogas treatment and digestion system, this project adopts two-stage connection technique (biological desulfurization + dry desulfurization) for biogas desulfurization. The innovative project uses the technique of biogas biological desulfurization in municipal sewage treatment plant, which is featured with its combination of alkali wash tower and bioreactor, and the formation of alkali liquid in bioreactor. That is, the running cost is greatly reduced by recycling the alkali from bioreactor if compared to the traditional wet desulfurization, and the removing effect of hydrogen sulfide is distinctive. According to data calculation of this project, in the case of general equation of one-time investment, the annual running cost of biological desulfurization is at least 1.2 million yuan lower than traditional wet desulfurization. Another advantage of this system is in its capability of recycling the sulfur. According to the data calculation, hundreds of kilograms 97% sulfur could be recycled everyday, and certain economic efficiency will be brought if proper market is opened. 5. 工程场地为滩涂地形,地址条件差,工程在控制投资的前提下,将90%以上的工艺管线集中敷设于地下管廊及综合管沟中,既节约地下空间,又利于管线的安装、检修及维护。同时将8座蛋形消化池及其管线楼连接,形成一个完整有序的地下空间及垂直交通,利于设备、管道、电缆等的施工及运行管理。 In consideration of the poor geographical condition (mudflat terrain) and investment controlling, over 90 percent of process pipelines are set in the underground pipeline colligate allure, which is beneficial for underground space-saving as well as the installation, repairing and maintenance of pipelines. Meanwhile, an integrated and ordinal underground space and vertical transport is formed by the connection of eight egg-shaped digestion tanks and pipeline buildings. It is favorable to the construction of equipments, pipes, and cables as well as the operation management. 6. 对污泥进泥系统,不采用直接将原污泥注入消化池的方式,而采用高效污泥接种器,将原污泥首先与消化池循环污泥混合后,再经过热交换器,将混合污泥加热到36-38度,再平稳地投入消化池。这样大大减少了原污泥对消化运行系统的冲击,提高了系统的效率。 For the sludge input system, high efficient sludge inoculation is used to replace the traditional way of inputting the raw sludge directly into the digestion tank. The raw sludge is initially mixed with the circular sludge in the digestion tank, then be heated to 36oC to 38oC by heat exchanger, and finally input into the digestion tank smoothly. In this way, the impact of raw sludge to digestion system is greatly minimized, and the system efficiency is enhanced. 7. 本项目采用35度中温厌氧消化,加热的关键设备热交换器采用外部热交换器,型式为套管式,因为此类热交换器的压力损失小,并且没有污泥板结的危险。热交换器的每个部分都装有自动除气装置,用于去除水循环中的气体。 This project adopts 35oC mesophilic anaerobic digestion with its key heating equipment – external tube-shaped heat exchanger, since this type of heat exchanger is with less pressure loss and no lumping risk. Automatic degassing unit is set for each part of heat exchanger to remove the air in water circulation. 8. 对应于蛋形消化池浮渣面小,我们在浮渣排除设备选型上,选择了速开速闭型的浮渣排放门,在有浮渣产生时,通过调整排渣液位,迅速排渣,效率很高。同时该浮渣门设备将严格保证气密性,确保系统运行的安全。 Due to the limited area for scum in the egg-shaped digestion, instant-opening-and-closing scum emission gate is chose when selecting the scrum-removing equipment. Through modifying the level of liquid scrum, a rapid and high efficient scrum emission is achieved. In addition, the system operation safety is ensured by the strict air tightness guarantee of the emission gate. 9. 出于系统安全性考虑,消化池顶各设备中日常有可能进行开盖操作的设备,如观察窗,在材料的选择上,必须防止材料接触过程中可能产生的火花,因此这部分材料我们选择的是青铜、黄铜。观察窗还装有一体式的雨刷。附属的喷射设备可以冲洗观察窗,设计考虑非常周全精细。 In consideration of system safety, equipments operated with open covers in the digestion tanks, such as inspecting windows, must be made of materials that free from producing sparks in the contacting procedure. Thus we select bronze and brass as materials. With a comprehensive and detailed design, the inspecting windows are equipped with integrative screen wipers, and the accessory spraying equipment is able to wash the windows. 10. 对于消化池内产生泡沫探测及防止泡沫进入沼气管路系统的考虑,为了在有泡沫的情况下,不影响设备运行,现代化的消化池气体进口系统中安装有泡沫捕集器。该设备可以在泡沫形成到一定阶段时发出信号,并且通过喷射水墙阻止泡沫进入气体系统。本项目将沼气集气罩与泡沫消除装置设计成一体化装置,以实现沼气的顺利排出。 In consideration of probing the bubbles from digestion tanks and preventing them into biogas pipes, bubble catcher is set in the gas input system of the modernized digestion. This equipment, with the presence of bubbles, does not affect the normal operation. This equipment sends signals when the bubble formation is entering a certain stage, and through spraying water wall the bubbles is prevented into the air system. This project integrates biogas trap and bubble-removing equipment to realize the successful emission of biogas. 11. 消化池顶通常采用两种形式的过压/负压保护设备:机械型和水力型。机械型设备操作烦琐,误操作之后会失去保护效果。当消化池进行卸压和恢复运行条件时,运行会造成负面影响。设备的设计已经考虑到过压和负压的最不利情况,同时保证了安全功能的自动运行。水力安全设备失效只可能导致系统内部的压力降,而不会对设备或消化池产生损坏。特殊的设计可以保证在最冷的温度下,安全装置仍然不会结冰。 Two types of overpressure/sub-pressure protection devices are often adopted at the top of digestion tanks, namely, mechanical type and water power type. The operation of mechanical type is complex, and the protection effect will be lost if improper operated. When the digestion tanks are in the processes of pressure relieving and operation resuming, negative impact will be caused. The design has fully considered the worst situation of overpressure and sub-pressure, and the automatic running of the safety function is ensured. The failure of water power type might lead to the pressure decreasing of the internal system, while does not impact the equipments or digestion tanks. The special design ensures the safety equipments free from ice in the coldest temperature. 12. 另外对应每台消化池,本项目还考虑了功能强大的阀组及管路系统,通过各组阀门的调节,以实现调试、运行、应急等不同场合的需求,同时还加设一般污水厂不曾加设的备用循环污泥系统,以实现调试初期或搅拌器出现故障时期保证消化池的搅拌效果。总之,实现了整个消化系统运行方式的高度灵活性、性能可靠及操作简便。 In addition, the powerful manifolds and pipeline system are selected for each digestion tank. Through the regulation of each valve, various needs are meet, such as debugging, running, and event of emergency. Meanwhile, different from other sewage treatment plants, a spare sludge circulation system is prepared to ensure the stirring effect in case the stirrer is broken down or during the initial debugging period. To sum up, this project achieves a successful digestion system mode, mainly embodied in its high flexibility, dependable performance, and simple operation methods.
