城市污水二级处理出水用于地下回灌的深度处理技术研究

Research on Advanced Treatment of Secondary Treated Municipal Wastewater for Groundwater Recharge

采用混凝沉降-砂滤-活性炭吸附-消毒工艺,对模拟城市污水处理厂二级处理工艺的SBR中试系统的出水进行了深度处理实验研究。实验结果表明,深度处理后的出水所检测的浊度、pH、COD、NH3-N、细菌总数等5项指标已经达到了《生活饮用水卫生标准》(GB5749-2006)。

The paper studies the advanced treating technologies of secondary treated municipal wastewater for groundwater recharge by means of a serials of experiments, including coagulation-sedimentation, sand filtration, activated carbon adsorption and disinfection. The results show that the indexes of turbidity, pH, COD, NH3-N and amount of bacterium detected in the study can meet the drinking water standard （GB5749-2006）.
