酒泉卫星发射中心的水污染治理及回用工程

酒泉卫星发射中心的污水处理及生态回用工程,充分结合当地自然环境恶劣、水资源短缺、温度低等实际特点,采用生化处理/人工湿地的组合工艺,污水处理量为9 000 m3/d,回用水量为8 500 m3/d。建设人工湿地面积为15 000 m2,人工湖面积为40 000 m2(60 000 m3)。二级生化出水水质达到了一级B排放标准,回用水质达到了《城市污水再生利用景观环境用水水质》(GB/T 18921—2002)标准。

Water Pollution Control and Reuse Project in Jiuquan Satellite Launch Center

Combined with poor local natural environment,insufficient water resources,low temperature and so on,the sewage treatment and ecological reuse project in Jiuquan Satellite Launch Center adopts the biological pretreatment and constructed wetland process.The treatment capacity is 9 000 m~3/d,and the reclaimed water capacity is 8 500 m~3/d with a constructed wetland of 15 000 m~2 and an artificial lake of 40 000 m~2 with a volume of 60 000 m~3.The secondary biochemical effluent reaches the first level B criteria,and the reclaimed water quality meets the requirements of Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use(GB/T 18921-2002).
