摘　　要：针对常规人工湿地系统处理高浊含氮磷的有机煤矿废水不佳的问题,采用PRB与人工湿地耦合的方法,进行砂箱模拟实验研究。实验结果表明,由无烟煤、钢渣及沸石构建的PRB强化垂直流人工湿地系统对NH4+-N、PO34--P、Mn2+、COD、SS的去除率分别达到88.84%、96.08%、98.98%、85.78%和94.00%,与常规人工湿地相比,具有处理效率高、水力负荷大、占地面积小等特点,更便于运行管理。Aimed at the low efficiency of treating organic coal mine wastewater with high turbidity, nitrogen and phosphorus by ordinary constructed wetland, simulation study on sand box is conducted with combination of ＋ PRB and constructed wetland. The results indicate that the NH4 -N, pO34- -P, Mn2＋ , COD, SS can be removed by 88.84% , 96.08% , 98.98% , 85.78% and 94.00% , respectively by the vertical flow constructed wetland system strengthened by PRB which is structured with anthracite, slag and zeolite. Compared with ordinary con- structed wetlands, the system is characteristic of higher treatment efficiency, higher hydraulic load, smaller oc- cupation and more convenient on operation and management.
