摘要
基质类型和水力停留时间是人工湿地污水处理系统的重要组成部分和主要运行参数,可直接影响系统的处理效果。本文选用两种混合基质(沸石+碎砖石、蛭石+碎砖石)构建人工湿地系统,比较其对畜禽养殖污水中COD、NH_4+-N、TP、Cu、Zn等污染物的的去除效果。结果表明:两种基质对COD、NH_4+-N、TP都有很好的去除效果,且沸石+碎砖石的去除效果略好于蛭石+碎砖石。
The matrix type and hydraulic retention time （HRT） are the most important parts and parameter of the constructed wetland sewage treatment system, which directly affect the treatment effect. In this paper, two kinds of mixed matrix （zeolite trubble, vermiculite＋rubble） were selected to construct artificial wetland system to evaluate its effect on the removal rate of COD, NH4--N, TP, Cu, Zn and other pollutants in livestock farm＇s wastewater. The results showed that two kinds of mixed matrix had very good effect on removal of COD, NH4^＋-N, TP, and the effect of zeolite＋rubble was just slightly better than that if vermi- culite＋rubble.
