目的:研究表流湿地工艺对微污染饮用水源的净化效果,从而进一步获取表流湿地工艺在饮用水源处理方面的应用性。方法:对表流湿地系统净化后的微污染饮用水源中的TP、TN、NO2^--N、NO3^--N、NH4^+-N、COD、pH等指标实施检测分析,应用的水质指标检测分析方法采用废水与水检测分析方法,将未经表流湿地系统净化前的微污染饮用水源的检测分析结果作为对比组数据,将经表流湿地系统净化后的微污染饮用水源的检测分析结果作为实验组数据,对比实验组与对比组数据,根据数据变化获取表流湿地工艺对微污染饮用水源的净化效果。结果:表流湿地工艺可以全面降低微污染饮用水源中的COD含量、TN含量、NH4^+-N含量、NH4^+-N含量、TP含量、重金属元素含量、细菌含量,实现微污染饮用水源的全面净化。结论:表流湿地工艺对微污染饮用水源有良好的净化效果。

To study the purification effect of surface-flow wetland technology on slightly polluted drinking water source,this paper studied the applicability of surface-flow wetland technology in the treatment of drinking water source.TP,TN,NO2^--N,NO3^--N,NH4^+-N,COD,pH and other indicators in micro-polluted drinking water sources purified by surface flow wetland system were detected and analyzed.The water quality indicators were detected and analyzed by the methods of wastewater and water detection and analysis.The micro-polluted drinking water sources without surface flow wetland system before purification were detected and analyzed.As the data of contrast group,the results of detection and analysis of micro-polluted drinking water source purified by surface-flow wetland system were taken as the data of experiment group,and the data of experiment group and control group were compared,and the purification effect of surface-flow wetland process on micro-polluted drinking water source was obtained according to the change of data.Result:Surface flow wetland technology can reduce the content of COD,TN,NH4^+-N,NH4^+-N,TP,heavy metal elements and bacteria in micro-polluted drinking water sources,and realize the comprehensive purification of micro-polluted drinking water sources.Surface flow wetland technology has good purification effect on slightly polluted drinking water source.
