几种水培植物对生活污水的净化效果比较
A Comparison of the Decontaminating Effects of Hydroponic Plants on Domestic Sewage
摘要
Abstract
The decontaminating effects of ten wetland plant species including Pontederia cordata,Iris ger-manica,Phragmitas communis, Acorus calamus Linn, Vetiveria zizanoides, Scirpus validus, Zizania latifolia, Cyperus alternifolius,Thalia dealbata,Echinodorus amazonicus were studied by using simulated solution culture experiment .The results showed:( 1 ) the annual average rates of pollutant removal of the ten plants were be-tween 40%and 70%,and the removal ability for 4 pollutants showed the order of TP ﹥NH4+-N﹥TN﹥COD.The highest TP removal rate was that of Thalia dealbata being 78%,the highest NH4+-N removal rate was that of Pontederia cordata being 74%,the highest TN removal rate was that of Iris germanica being 70%, the highest COD removal rate was that of Pontederia cordata being 65%;( 2) the average seasonal TP removal rates of the ten species showed the order of autum ﹥ summer ﹥ spring﹥ winter,however the NH4+-N,TN and COD removal rates showed the order of summer ﹥spring﹥autum﹥winter .关键词
