摘　　要：针对传统池塘养殖排放水净化设施效率低、占地面积大等问题,研制了立体弹性填料和陶粒生物滤床,构建了生物滤床净化池塘养殖排放水系统,系统由养殖池塘、立体弹性填料滤床和陶粒滤床等组成.通过分析对池塘排放水净化效果,确定了适合池塘养殖排放水净化处理的水力停留时间(HRT);通过分析池塘水质、藻类变化等,确定了生化滤床净化再循环利用系统的池塘水体循环量、生物滤床与养殖池塘组成比例等参数.根据以上参数运行循环水养殖系统,可使池塘水体中的营养盐维持在较低水平,同时还可以优化水体中的藻类结构,减少养殖用水和污染排放.该系统已成功应用于多个池塘养殖场,为池塘养殖排放水净化再利用提供了一种新方法.Two bio-fiher beds packed witi~ elasticity plastic filter or ceramsites were developed for the problems of low efficiency and large occupied area by traditional facilities of water purification in pond aquaculture. Additionally a bio-filter purification system for effluent in pond aquaculture was constructed. This system consisted of aquaculture ponds and these two kinds of bio-fiher beds. The suitable hydraulic retention time（HRT） for purification of pond aquaculture effluent was determined by analyzing the purification effect. The optimal pond water circulation rate and area ratio between bio-fiher beds and aquaculture ponds were determined by analyzing the pond water quality and changes of algae. When running the system at these optimized parameters, the nutrient of pond water can be maintained at low level, meanwhile, the structure of algae community has been optimized, and the water consumption and pollution emission are reduced. This system was used successfully in several pond aquaculture farms. It would be a new method for reuse of pond aquaculture effluent.
