摘  要：
[目的]探究石龙芮和酸模两种挺水植物对生活污水的净化效果。[方法]采用无土栽培的石龙芮、酸模处理生活废水,重点研究影响污水处理效果的植物生物量、水力停留时间(HRT)的两个因素。[结果]静态试验中两种试验植物对氨氮(NH4+-N)、总氮(TN)、总磷(TP)均有较好的处理效果,平均去除率能够分别达到100%9、0.52%和88.77%;植物系统对污染物的处理效果与生物量有关,同种植物随着生物量的增加对总氮、总磷的去除率提高,而且HRT越短,去除率的提高越显著;系统最佳的HRT为5 d左右,过长或过短都达不到最佳的处理效果。[结论]石龙芮、酸模这两种水生植物因其较好的去除污染物的能力,适合于构建人工湿地污水处理系统。但其正常运行的优化工艺参数仍需要更深入的研究。

摘  要：
[Objective] The aim of the research was to probe into the purification effects of 2 kinds of emergent plants of Ranunculus sceleratus L.and Rumex acetosa L.on the domestic sewage.[Method] R.sceleratus and R.acetosa in soilless culture were taken to treat the domestic sewage.2 factors of plant biomass and hydraulic retention time(HRT) that affected the sewage treatment effect were studied mainly.[Result] In static test,2 kinds of tested plants both had better treatment effects on ammonia-N(NH4+-N),total nitrogen(TN) and total phosphorus(TP) and the average removal rates could reach 100%,90.52% and 88.77% respectively.The treatment effect of plant system on pollutants was related with biomass.The removal rate of TN and TP in the same kind of plants was increased with the increasing of biomass.The shorter HRT was,the increasing of the removal rate was more significant.The optimum HRT in the system was about 5 d and the optimum treatment effect couldn't be achieved if HRT was too long or too short.[Conclusion] Because the two kinds of aquatic plants of R.sceleratus and R.acetosa had better removal capability of pollutants,they were suitable for constructing artificial wetland sewage treatment system.But the optimized technology parameters in its normal operation still needed more researches.
