河流支流入河口水质处理系统工程设计初探

为了改善流溪河水体水质,通过设计膜生物反应器-人工湿地组合工艺系统,来提高流溪河支流入河水质。根据支流入河口的地理位置,在支流的末端建造3个污水拦截坝,将污水依次截留形成两个处理阶段.系统设计利用了水位差为水流提供动力,充分利用生物膜法占地面积小、处理效率高、操作简单及对CODcr、SS、NH3-N、微生物的去除效果好,并结合了人工湿地技术具有生态、廉价、较高的N和P去除率、易于管理的优点。

Design of Water Treatment System Engineering in Outfall of Tributary of River

To protect the Liuxihe river, through designing the combined system with membrane bioreactor and constructed wetland to improve water quality of its tributary. according to geographical position of outfall, building three dams in the end of tributary and forming two water treatment stages. It supplies power to water current by water lever and makes use of the advantage of the membrane bioreactor such as less occupation of land, high efficiency of treatment, simple operation, the good effect of removal of CODcr, SS, NH3-N and microbe, and the advantage of constructed wetland such as ecology, cheap, the good effect of removal of TN and TP, easy manage.
