【摘要】 介绍了采用MBR工艺处理小区优质杂排水并回用的设计和运行情况。实践表明,该工艺在水力停留时间为6h时,对BOD5、SS、NH3-N、浊度、色度的去除率能稳定达到90%以上,出水水质满足《城市污水再生利用景观环境用水水质》(GB/T18921—2002)的要求。工程投产后可节省自来水27.1×104m3/a。更多还原

【Abstract】 The paper introduces the design and operation of a MBR Process used for reclaimed water reuse in residential region. The practical operation shows that the removal efficiencies of BOD₅, SS, NH₃-N, turbidity and color are all higher than 90% under HRT of 6 h. The effluent quality satisfies The Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use （GB/T 18921-2002）. 27.1×104 m3/a of drinking water may be saved after the project being put into operation.更多还原
