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。结果表明：3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99．8％、82．2％和93．3％；三者对浊度也有很强的去除效果，分别得到了99．3％、90．6％和82．8％。活性炭与炉渣混合基质对生物需氧量（COD）和总氮（TN）去除比陶粒和火山岩强，可达到93．2％和68％。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。
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. 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, 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%. For the time span from 0 to 5 days, criteria of polluted water reduced quickly then the purification effect of polluted water trended to be stable.
