摘要： 选用活性炭与炉渣（3:1）、陶粒和火山岩作为垂直流人工湿地基质，进行不同基质净化畜禽养殖废水的效果研究，以及基质对污水的净化效果与时间关系的研究。结果表明：三种基质对总磷（TP）都有很好净化效果，最大去除率分别得到了99.6％、79.8％和92.3％，与此同时，三者对浊度也有很强的去除效果，分别得到了98.5％、90..6％和82.8％.其中活性炭与炉渣混合对生物需氧量（COD）和总氮（TN）去除比陶粒和火山岩强，可达到了93.2％和68％.火山岩和陶粒对COD去除率为58.6％和53.6％，而两者对TN最大去除率为38.2％和14.4％，对硝态氮去除率分别得到74.1％和61.3％。在0～5天这个时间段，模型内污水各项指标降低迅速，随后对废水的净化效果趋于稳定。

Abstract: We selected activated carbon , slag, ceramsite and volcanic as the substrates of vertical flow wetlands and studied the effect of different substrates on livestock and poultry breeding waste as well as the relation between the substrates purification effect on polluted water and time. The results indicate that all of the three substrates had good purification effect on total phosphate (TP), the maximum degradation was 99.6﹪,79.8﹪ and 92.3﹪ respectively, meanwhile three of all had good degradation effect on turbidity and they were 98.5﹪,90.6﹪ and 82.8﹪ respectively. Among substrates the mixture of activated carbon and slag needed more COD(biological oxygen demand) and had better degradation effect of TN (total nitrogen) than ceramsite and volcanic, they achieved 93.2﹪ and 68﹪ while volcanic and ceramsits can get to 58.6﹪ and 53.6﹪ for COD’s degradation respectively, but both maximum degradation of TN only got to 38.2﹪ and 14.4﹪,also their degradation of NO- 3 were 74.1﹪and 61.3﹪respectively. For the time span from 0to 5 days, criteria of polluted water reduced quickly then the purification effect of polluted water trended to be stable.
