摘要
天津市张贵庄污水处理及再生利用一期工程是天津市中心城区最后一座大型污水处理厂,也是天津市目前处理标准最高、功能最全的污水处理厂,主要包括20×104m3/d污水厂、6×104m3/d再生水厂,厂内污泥处理处置规模为300 t/d。污水厂采用AO脱氮除磷/反硝化深床滤池工艺,出水水质执行一级A排放标准;再生水厂采用双膜法/臭氧脱色工艺,出水主要用于工业循环冷却,部分作为城市杂用水;污泥处理处置采用好氧发酵技术,产品用于园林绿化。
The first-phase project of wastewater treatment and reclamation at Tianjin Zhang-guizhuang is the last large-scale wastewater treatment plant in the central area of Tianjin City, and it is al-so the highest standards and the most complete functions in Tianjin City, which has wastewater treatment capacity of 20 ×10^4m^3/d, reclaimed water treatment capacity of 6 ×10^4m^3/d and sludge treatment ca-pacity of 300 t/d. AO process for nitrogen and phosphorus removal and denitrification deep-bed filter are used for wastewater treatment, and the effluent quality meets the first level A criteria. Dual membrane process and ozone decoloration are used for reclaimed water treatment, and the effluent is used as indus-trial circulating cooling water, and part of which is used as urban miscellaneous water. Aerobic fermenta-tion technique is used for sludge treatment and disposal, and the products are used for garden greening.
