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、NH_4^+-N和NO_2^--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%;NH_4^+-N的去除率为35.27%至99.13%,平均去除率为67.84%;NO_2^--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。
In this paper,aquaculture wastewater was treated with combinational constructed wetlandssystem. The treated effects of TP,TN,NH4 +-N and NO2--N were explored. The experimental resultsindicated that removal efficiencies of TP,TN,NH4+-N and NO2--N were 82. 45%-99. 79%(mean value92. 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 thatremoval efficiency of TP was better than that of TN and the purification effect of severe eutrophic water wasbetter than that of special eutrophic water.
