| 摘 要： | 采用建筑废砖为填料构建垂直流人工湿地,以常规碎石床湿地为对照,研究了建筑废砖人工湿地对农村生活污水的净化效果。结果表明:生活污水经废砖湿地系统处理后,出水比较稳定。废砖湿地系统对TP、TN和NH+4-N的去除效果显著高于常规碎石床湿地系统,其去除率分别可达到91%、66%和78%。废砖湿地系统与常规碎石床湿地对COD的去除率均较高,去除率可达90%左右。废砖湿地系统出水水质可满足GB 18918—2002《城镇污水处理厂污染物的排放标准》一级B及以上限值。

| Abstract: | The paper studied vertical flow constructed wetlands with building waste brick as fillers and explored purifying effect of constructed wetlands in rural sewage with gravel bed wetlands as the control.Results showed that after treatment with waste brick wetland system,rural sewage exhibited a relatively stable discharge.Waste brick wetland system posed significantly higher removal efficient of TP,TN,and NH4+-N than gravel bed wetlands,reaching 91％,66％,and 78％,respectively.Waste brick wetland system and gravel bed wetlands both featured high removal rates of COD,which reached 90％.Effluent quality from waste brick wetland system met the B level of grade Ⅰ of "Pollutant Discharge Standard of Municipal Wastewater Treatment Plants" (GB 18918-2002). |
