| 摘 要： | 为了研究人工湿地基质在处理农业径流中的作用,对农业径流人工处理湿地中的基质展开研究。结果表明:人工湿地基质能够吸附水中一定的污染物质,成熟基质基质具有很强的污染物降解能力,对水中污染物的去除发挥重要作用。湿地基质对实验农业径流的COD、TN、TP和NH4+-N的去除率分别为41%,50%,49%和%52%。出水中CODcr、TN、TP、NH4+-N含量分别达到Ⅱ类水质的含量,Ⅴ类水质的含量,Ⅴ类水质的含量和Ⅲ类水质的含量。

| Abstract: | In order to study the role of wetland substrate on the purifying agricultural runoff,Substrate of constructed wetland for treatment agricultural runoff was studied.Results show that the substrate in the constructed wetland systems can absorb a lot of pollutants,and there were many microorganisms on the mature substrate surface.Experiment showed that the substrate had a strong ability of biodegradation,and played an important role in the process of pollutants removal.the removal efficiency of chemical oxygen demand （CODcr）,total nitrogen（TN）,total phosphorus （TP）andammonium nitrogen（NH 4 ＋ -N） in the constructed wetland substrate were 41%,50%,49% and 52%,respectively.After the disposal of the wetland substrate,Effluent COD,TN,TPand NH 4 ＋ -N were GradeⅡ,Grade Ⅴ,GradeⅤand Grade Ⅲ,respectively. |
