为筛选出对农村散户生活污水出水净化效果好的水生植物,以29种常见水生植物为材料,对模拟农村生活污水出水进行净化能力比较,并将不同植物对污染物的去除能力进行聚类分析。结果表明,有植物处理对污染物的去除率明显高于无植物对照,水力停留时间(HRT)对净化效果具有显著影响,水生植物在早期对污染物净化速率快。有植物处理对TN(总氮)的净化率比无植物对照组提高6.21%~26.66%,对NH3-N(氨氮)、TP(总磷)、CODCr(化学需氧量)、SS(悬浮固体)的净化率分别提高7.03%~23.92%、17.40%~28.13%、7.47%~18.62%、8.90%~13.00%。其中凤眼莲在试验前期对TN、NH3-N、TP净化具有一定优势,但试验后期对污染物净化能...

In order to screen aquatic plants for the effective purification of rural retail sewage water, 29 common aquatic plants were tested to compare their removal capacity for total nitrogen(TN), ammonia nitrogen(NH3-N), total phosphorus(TP), chemical oxygen demand (CODCr), and suspended solid(SS)in a septic tank effluent system. The removal ability of different plants on pollutants was determined and clustering analysis was conducted. The results showed that the removal rate of pollutants in control without plant was significantly lower than that of plant treatment. Treatment time significantly aff...
