一种新型人工湿地强化农田退水脱氮研究

摘要

In lifht of farmland low carbon-sulfur ratio and nitrofen removal difficulty,the paper compares nitrofen removal effect of different reac-tors with different hydraulic retention time,and compares nitrofen removal efficiency of carbon-sulfur couplinf reactors with different hydraulic retention time under 17. 7 mf/ L of inflow TN concentration,and finally points out that:there will be wide application prospect of applyinf car-bon-sulfur couplinf for forcefully removal nitrofen.%针对农田退水碳氮比低，脱氮难度高等问题，比较了不同水力停留时间下，各个反应器的脱氮效能，在进水 TN 浓度为17.7 mf／ L 条件下，比较了不同水力停留时间下碳硫耦合反应器脱氮效能的问题，指出利用碳硫耦合进行强行脱氮具有广阔的应用前景。
