摘　　要：提出了以厌氧—好氧活性污泥法进行二级处理，以气浮充氧—好气滤池进行深度净化的城市污水再生全流程。其特点是：生化反应池污泥不膨胀，操作方便运行稳定；深度净化中将物化与生化作用相结合，不但能有效地去除悬浮颗粒，而且能进一步去除溶解性有机物。该流程大幅度地提高了再生水质，与传统流程相比，深度净化水水质改善率ＣＯＤＣｒ、ＢＯＤ５为１０～３０％，ＳＳ、色度为２０％，大肠菌值为９０％。The thesis describes a complete flow process of municipal wastewater renovation with anaerobic aerobic activated sludge treatment as secondary one and floatation oxygenation aerobic filter as deep purification.Features of the process are as follows:1.No sludge bulking occurring in the biochemical reaction tank.2.Easy operation and steady running.3.The combination of biochemical action with physicochemical action in deep purification will remove not only suspended particulate efficiently but also soluble organic matters.4.The flow process has enhanced the reclaimed wastewater quality remarkably. Comparing with the conventional flow process,this flow process has increased CODcr or BOD 5 by 10～30%,SS or color 20%,and coli index by 90%.
