摘要
天津市纪庄子污水处理厂1984年开始运营,其采用普通活性污泥法,两级中温污泥消化为主的处理工艺,经不断地技术改造、设备更新、完善工艺、加强管理,十年来一直运行稳定,共向天津市提供城市污水二级净化水约8.3亿m^3,处理污泥196万m^3,生产沼气1245m^3,沼气发电450万kw·h.文中根据污水厂历年来的运行数据,评价了污水、污泥的处理效益,分析了生产成本组成和能耗变化.
Stable performance has been obtained in the last decade since the Jizhuangzi Wastewater Treatment Plant in Tianjin was put into operation in 1984 for which conventional activated sludge process and two stage mesophilic sludge digestion were adopted as main treatment measures. 830 million cubic meters of wastewater have been treated with secondary treatment, 1. 96 million cubic meters of sludge disposed and 4. 5 million kWh of electricity generated by methane utilization as a result of continues technical reform, renovation of equipments, process improvement and management modification of the plant. On the basis of the operational data the efficiencies of wastewater and sludge treatment have been estimated and the composition of operational expenses and energy consumption studied in this paper.
