摘　　要：主要研究了池塘养殖节水循环系统一、二、三级湿地净化池和排水渠的水质净化效果,养殖池塘设置植物漂浮带和应用复合微生态制剂对池塘养殖水体的水质进行净化。结果表明:池塘养殖节水循环系统能显著降低水体COD、TN、TP、NH4+-N,提高水体DO以及水体透明度,池塘节水率达30.96%,表明该循环系统净化水质效果显著。三级净化池和排水渠净化与池塘生态调控相结合,实现高效生态节水养殖,其中净化与养殖占地面积比为1∶10。The water purification effort was studied in the three grade water purifying ponds and inflow drainage channels.The water quality was purified by plant floating zone and microbial ecological agents in the ponds.The test results showed that the water saving circulatory system in ponds can remove CODMn,TN,TP and ammonia nitrogen obviously,increase dissolved oxygen and transparency significantly.The water-saving rate is as high as 30.96%.Therefore,the water saving circulatory system can purify water significantly.Three grades water purifying ponds combined with inflow drainage channels can efficiently purify water and save water.The ratio of Purification and Culture covers area is 1：10.
