摘要:
为有效改善深圳市茅洲河流域水环境，沙井污水处理厂二期工程（35×104 m3/d）选用前置调蓄池（4×104 m3）的多段强化脱氮改良型A2/O+矩形平流沉淀池处理工艺。项目建成投产以来，处理效果良好，出水水质全面优于《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准。调蓄池与污水处理厂合建可以集约用地、节省投资，且有效解决了雨季合流污水污染问题。同时，该污水厂采用半地下式设计方案，上盖建成供周边居民休憩、健身的体育公园，经济、社会效益双丰收。
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.
