摘要: 采用垂直流和水平潜流人工湿地构成复合型人工湿地系统,对水产养殖废水进行处理,研究该复合型人工湿地系统对污水中TP、TN、NH4+-N和NO2--N的去除效果。结果表明:TP的去除率为 82. 45%至99. 79%,平均去除率为 92. 75%;TN 的去除率为 74. 09%至 84. 63%,平均去除率为 79. 33%;NH4+-N 的去除率为 35. 27%至99. 13%,平均去除率为67. 84%;NO2--N的去除率为53. 62%至75. 98%,平均去除率为63. 38%。该复合型人工湿地系统对TP去除率优于TN,并对重富营养化水体的净化效果优于异常营养化水体。

Abstract: In this paper,aquaculture wastewater was treated with combinational constructed wetlands system. The treated effects of TP,TN,NH4+-N and NO2--N were explored. The experimental results indicated that removal efficiencies of TP,TN,NH4+-N and NO2--N were 82. 45%-99. 79%(mean value 92. 75%),74. 09%-84. 63%(mean value 79. 33%),35. 27%-99. 13%(mean value 67. 84%)and 53. 62%-75. 98%(mean value 63. 38%),respectively under the experimental conditions. It can be found that removal efficiency of TP was better than that of TN and the purification effect of severe eutrophic water was better than that of special eutrophic water.

Key words: combinational constructed wetlands system, aquaculture wastewater, eutrophication, nitrogen removal, phosphorus removal
