- Abstract:
- The planned treatment capacity of Taihe sewage treatment plant in Shanghai is 60×104 m3/d, and the treatment capacity of the first phase is 40×104 m3/d, in which all the structures were constructed underground. The process of the sewage treatment plant consists of primary sedimentation tank, AAO biological reactor, secondary sedimentation tank, high efficiency sedimentation tank and denitrification deep bed filter, and the effluent water quality is required to meet first level A limitations of the discharge standard. The sludge treatment process includes mechanical concentration and low temperature vacuum dehydration and drying, and the sludge is transported out for incineration after the water content is no more than 40%. Taihe sewage treatment plant is a complete underground sewage treatment plant, and the whole process is located in the underground box. In addition, appropriate reservation was made in the underground box for long-term standard upgrading and water reuse, and the storage tank with a volume of 15×104 m3 was designed at the head of the sewage treatment plant. After operation of the sewage treatment plant, all effluent indexes had reached the design standard.
