摘　　要：报道了一种新的高效低能耗的污水处理塘系统的中试研究结果．本生物塘系统分为三个功能区域，分别为污水净化区，水质修饰区和综合利用区．水生维管束植物呈带状分布于塘系统中，在时间上和空间上进行不同搭配组合．较之传统氧化塘和一般的水生植物塘、综合生物塘的处理效果较好，ＣＯＤ、ＢＯＤ、ＴＳＳ、氮、磷等污染组分去除效率较高，细菌，病毒及诱变活性明显下降。在污水净化的同时，收获大量的水生植物及鱼，蚌等水产品．水质明显改善，出水可用于水产养殖和农业灌溉．A low-cost pond system was operated to purify wastewater from amedium-sized Chinese city.The experiments were conducted in 3 phases andthe system was divided into 3 functional regions.macrophytes were planted inseries in the ponds. Operation parameters in various pollution and hydraulicloadings were studied. The pond system revealed greater purification efficie-ncies than conventional oxidation pond and general macrophyte pond.Thesystem attained Ligh reductions in COD,BOD,TSS,N,P, bacteria,virusand mutagenic effect. The other water quality parameters were also improvedto some extent. The allelopathic effect of the macrophyted on algae was te-sted. A lot of macrophyte biomass and other aquatic products were harvestedfrom the ponds at the same time. The effluent from this system could beused in fishery and irrigation.
