- Abstract:
- To alleviate the current insufficient treatment capacity of the Hanxi sewage treatment plant and realize the quality and efficiency improvement of sewage treatment system in Dongxihu District, Wuhan, two emergency temporary decentralized sewage treatment plants with a total capacity of 13×104 m3/d, which adopts the rapid purification of sewage using sedimentation integrated rectangular airlift loop reactor (A/RPIR) and magnetic coagulation sedimentation treatment process were newly built. The main structure of the project was prefabricated in factory modular and assembled by on-site welding. The construction period of the 10×104 m3/d sewage treatment plant is about 120 days and the sewage treatment system unit occupies an area of 0.31 m2/（m3·d-1）, which is far lower than the recommended standard value. The operation results showed that the sewage treatment system has a certain impact load resistance, the effluent indexes could stably reach the first?level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and the comprehensive operating cost was 0.550 2 yuan/m3.
