摘    要:利用复合型人工湿地系统净化处理农业面源污染,研究了湿地系统对营养物质、重金属的去除效果。结果表明,在低污染负荷的运行情况下,湿地系统对总氮、氨氮、硝态氮、亚硝态氮的去除率分别为44.11%、18.90%、52.86%和73.32%;对总磷、高锰酸盐指数和叶绿素a的去除率为49.46%、16.77%和75.82%;处理后的水质较处理前可提高1~2个水质等级。湿地系统对有机物的去除效果不明显,而对叶绿素的净化效果显著。湿地系统对重金属的去除有显著效果,对铜、锌、砷、硒、汞、铬、铅的去除率分别为74.7%、85.3%、21.2%、40.0%、30.4%、41.3%和33.5%。湿地系统对总磷和叶绿素a的去除呈极显著差异,对亚硝态氮和CODMn呈显著差异。经湿地系统处理后,出水水质完全达到温室蔬菜灌溉水环境质量标准的要求。

关 键 词:复合型人工湿地系统  农业灌溉用水  水质净化  去除率

Abstract:Compound constructed wetland was applied in treating agricultural irrigation polluted water studied the removal effect on nutrients and heavy metals influenced by it.The results indicated that in the case of low pollution load,the removal rate on total nitrogen(TN),ammonia nitrogen(NH3-N),nitrate nitrogen(NO3-N) as well as nitrite nitrogen(NO2-N) in wetland system were 44.11%,18.90%,52.86% and 73.32% respectively.The removal rate on total phosphorus(TP),organic compounds(CODMn) and chlorophyll a(Chla) were ...
Keywords:compound constructed wetland system  agriculture irrigation water  water purification  removal rate
