摘　　要：由潜流和表面流湿地组成复合人工湿地,与池塘有机结合构成鱼塘-湿地水循环系统应用于草鱼苗种培育,研究了该系统对池塘水质的改善效果。结果显示:在760 mm/d的水力负荷率条件下,复合湿地系统对NH4+-N、NO2--N、NO3--N、TN、TP、COD和TSS的平均去除率分别为(33.56±3.71)%、(50.73±3.95)%、(46.33±4.95)%、(27.99±2.78)%、(58.15±3.38)%、(29.60±2.24)%和(84.49±1.77)%;湿地出水水质符合渔业水质标准(GB11607-89)要求。结果表明鱼塘-湿地水循环系统对养殖用水具有较好的净化效果。A fishpond-wetland water recycling system, which was made of compound constructed wetland （combine substrate flow wetland and flow surface wetland） and fishpond, was used to breed Grass carp fingering. The improvement of ecological recycling aquaculture system for aquaculture wastewater quality was studied. The results showed that under 760 mm/d hydraulic loading rate, the average removal rate of constructed wetland system for NH4^＋ -N, NO2^- -N, NO3^- - N, TN, TP, COD and TSS were （ 33. 56 ± 3. 71） % , （50.73 ±3.95）%, （46.33 ±4.95）%, （27.99 ±2.78）%, （58. 15 ±3.38）% , （29. 60 ±2. 24）% and （84.49 ± 1.77）%, respectively. The effluent of wetland system was up to national water quality standard for fisheries. So the fishpond-wetland water recycling system had good purification efficiency for aquaeuhure wastewater.
