The invention discloses a municipal wastewater purifying method and belongs to the field of environmental protection. The principle of the method is as follows: nitrogen and phosphorus in domestic wastewater are absorbed by Cymbella and Synedra growing on the surface of stone, so that nitrogen, phosphorus and other organic matters are removed. The method has the advantages of energy saving, high efficiency, good effluent quality, small occupation area, little investment, low treatment cost, easy operation and the like, and determination proves that 98% of nitrogen and 96% of phosphorus in the wastewater can be removed through treatment. 本发明公开了种城市生活污水的净化方法，属环境保护领域。本方法原理是：利用在石块表面生长的桥弯藻Cymbella和针杆藻Synedra将生活污水中的氮、磷吸收，从而达到去除氮、磷和其它有机质的目的。本方法具有节能、高效、出水水质好、占地面积小、投资少，处理成本低、易于操作等优点。经测定，经过处理可去除废水中98％的氮和96％的磷。
