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。
Aiming at the problem that the conventional constructed wetland system is not good to deal with the waste water of organic coal mine with high turbidity and nitrogen and phosphorus, a sand box simulation experiment is carried out using the method of coupling PRB and constructed wetland. The experimental results show that the removal rates of NH4 + -N, PO34 - P, Mn2 +, COD and SS of PRB strengthened vertical flow constructed wetland system constructed by anthracite, steel slag and zeolite are respectively 88.84%, 96.08%, 98.98% and 85.78% And 94.00% respectively. Compared with the conventional constructed wetland, it has the characteristics of high treatment efficiency, large hydraulic load and small area, which is more convenient for operation and management.
