摘要
本文研究了在高寒地区生活污水温度较低等特殊情况下,硫自养反硝化人工湿地对污染物的去除效果。研究中将硫自养反硝化工艺和垂直潜流人工湿地进行组合,并对比其与普通型人工湿地在处理高寒地区低温生活污水时的污染物去除效果。结果表明,硫自养反硝化人工湿地由于添加了硫铁矿功能区,比普通人工湿地对低温生活污水中COD、NH_(4)^(+)-N、TN和TP的去除效果更好,出水COD浓度低于40mg/L、出水NH_(4)^(+)-N浓度低于10mg/L、出水TN浓度低于12mg/L、出水TP浓度低于0.3mg/L。
In response to the removal efficiency of sulfur-based autotrophic denitrification constructed wetlands under the low-temperature conditions of domestic wastewater in alpine regions,this study combines sulfur-based autotrophic denitrification(SAD)technology with vertical subsurface flow constructed wetlands,and compares the pollutant removal performance with conventional constructed wetlands.The results show that the SAD constructed wetland,equipped with a pyrite functional zone,significantly outperforms the conventional wetland in removing COD,NH_(4)^(+)-N,TN,and TP from low-temperature domestic sewage.Effluent concentrations were consistently below 40mg/L for COD,10mg/L for NH_(4)^(+)-N,12mg/L for TN,and 0.3mg/L for TP.
