摘　　要：在分析污水厂二沉池出水水质特点的基础上,利用接触过滤/磁性树脂组合技术对其进行处理,分析了对污染物的去除效能。研究结果表明,二沉池出水存在的主要问题是总氮含量较高,且以硝态氮为主;组合技术对二沉池出水中的主要污染物均具有较好的去除效果,处理出水的总氮、总磷、COD、浊度分别为10 mg/L、0.1 mg/L、25 mg/L、2.0 NTU左右;组合技术的运行费用约为0.3元/m3。结合城市污水回用的相关水质标准,该组合技术可作为污水处理厂升级改造或深度处理的可供选择技术。On the basis of characteristic analysis of secondary effluent from WWTP, the combined process of contact filtration and magnetic ion exchange resin was used to treat the effluent, and the removal efficiency of pollutants was analyzed. The results show that the main problem of the effluent is higher content of TN, which is mainly comprised of nitrate. The combined process can effectively remove the pollutants in the effluent, TN, TP, COD and turbidity in the treated effluent are 10 rag/L, 0. 1 rag/L, 25 mg/L and 2.0 NTU respectively. The operation cost of the combined process is 0.3 yuan/m^3. Based on the relevant standards for municipal wastewater reuse, the combined process can be used as one of technologies for upgrading and reconstructing of WWTP or advanced wastewater treatment.
