- Abstract:
- In order to effectively improve the water environment of Maozhou River basin in Shenzhen City, the second phase of Shajing sewage treatment plant was designed using the multi-stage enhanced denitrification improved A2/O+rectangular horizontal sedimentation tank process with a pre-storage tank(4×104 m3). Since the project was completed and put into operation, the treatment effect was good. The effluent quality was superior to the first level A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002）. The joint construction of the storage tank and the sewage treatment plant could save land and investment, and effectively solve the problem of confluent sewage pollution in the rainy season. At the same time, the sewage treatment plant adopts the semi-underground design scheme, and a sports park was built on the top for the surrounding residents to rest and keep fit, which obtain both economic and social benefits.
