摘要
采用强化预处理+人工湿地工艺处理农村污水,该工艺能够稳定运行,煤渣和砖渣1∶1配比填料适用于人工湿地。出水COD、NH3-N、SS均达到《城镇污水处理厂污染物排放标准》中一级B标准,年实现COD、NH3-N削减量分别为9.94 t、1.72 t。
Intensive preconditioning ＋ constructed wetland wastewater treatment technology of rural waster-water was utilized. The results showed that the process was stable, 1∶1 ratio of cinder and slag brick filler was suitable for wetlands. The Effluent COD, NH3-N, SS meet the requirements of ＂The Emission Standards Ur-ban Sewage Treatment Plant ＂B standard, the annual COD, NH3-N reductions are 9. 94 t, 1. 72 t.
