采用厌氧生物滤池(AF)-人工湿地-生态塘工艺处理养殖废水.结果表明:AF设置在人工湿地的前端能极大地降低SS的含量,有效预防人工湿地的堵塞.人工湿地采用跌水曝气方式,节约了能源及建设维护费用;采用波式潜流的流态,为氮的去除创造了较好的条件.生态塘设置在波式潜流人工湿地后端,它能强化对氮、磷的处理;工艺对COD_(Cr)的去除率约为80.30%,SS去除率约为94.69%,NH_3-N去除率约为73.39%,TP的去除率约为86.78%.
採用厭氧生物濾池(AF)-人工濕地-生態塘工藝處理養殖廢水.結果錶明:AF設置在人工濕地的前耑能極大地降低SS的含量,有效預防人工濕地的堵塞.人工濕地採用跌水曝氣方式,節約瞭能源及建設維護費用;採用波式潛流的流態,為氮的去除創造瞭較好的條件.生態塘設置在波式潛流人工濕地後耑,它能彊化對氮、燐的處理;工藝對COD_(Cr)的去除率約為80.30%,SS去除率約為94.69%,NH_3-N去除率約為73.39%,TP的去除率約為86.78%.

AF-DWWSCW-EP union process was employed to treat the cultivation wastewater.The results indicated that anaerobic biological filter should be put in the front of constructed wetland and it could reduce the SS,prevent the clog in constructed wetland efficiently;constructed wetland with dropping aeration could save energy consumption and the cost of construction and maintenance;wave and subsurface-flow created a better condition for nitrogen removal;Eco-pond should be put in the back of drop water wavy subsurface constructed wetland,which would intensify the removal of nitrogen and phosphorus.AF-DWWSCW-EP union is efficient in the purification of cultivation wastewater,the removal rate of CODcf,SS,NH_3-N,and TP is about 80.30%,94.69 9,6,73.39%,and 86.78%respectively.
