摘要
[目的]筛选对农村生活污水净化效果较好的挺水植物.[方法]选用花叶芦竹(Arundo donax)、翠芦莉(Ruellia brittoniana)、水葱(Scirpus tabernaemontani)3种挺水植物模拟潜流人工湿地处理生活废水,研究3种植物对氨氮(NH4+-N)、总磷(TP)、化学需氧量(COD)的净化效果.[结果]花叶芦竹、翠芦莉、水葱对水体中NH4+-N、TP、COD的去除效果明显,168 h后3种植物对NH4+-N的去除效率达到94.6%,而最低的COD的去除效率也达到89.8%.[结论]采用湿地植物处理农村生活污水具有投资成本少、处理效果好、出水水质好等特点.
Abstract
[Objective]To screen the emergent plants which have better purifying effect on rural sewage.[Method]Subsurface flow constructed wetland for treatment of domestic wastewater by simulation of Arundo donax,Ruellia brittoniana,Scirpus validus.The purification effects of three plants on NH4+-N,TP and COD were studied.[Result] The results showed that the removal rate of NH4+-N,TP and COD in the water of the three plants was obvious.After 168 hours,the removal rate of ammonia nitrogen for the three plants reached 94.6%,while the minimum COD removal rate was 89.8%.[Conclusion] The treatment of rural domestic sewage with wetland plants has the characteristics of low investment cost,good treatment effect and good effluent quality.
