农村地表饮用水锰(铁)超标处理技术研究综述

Research on treatment technologies for excessive manganese(iron)in rural surface drinking water

近年来,我国部分地区因超采导致地下水位下降,地表水逐渐承担农村供水主要水源的角色,而锰(铁)超标的现象一直存在,给农村供水提出了新的要求。研究根据水利部和安徽省保护和治理地表水污染的精神,从研究现状出发阐述物理处理技术、化学处理技术和生物处理技术的具体操作方法,阐述如何根据实际情况选择锰(铁)超标处理技术,就现状和处理技术的结合从政策、技术层面提出建议并展望未来研究方向,指出锰(铁)超标处理技术研究对农村供水和环境保护的意义和影响。

In recent years,some areas in China have experienced a decrease in groundwater levels due to overexploitation,and surface water has gradually taken on the role of the main water source for rural water supply.However,the phenomenon of excessive manganese(iron)has always existed,posing new requirements for rural water supply.Based on the spirit of the Ministry of Water Resources and Anhui Province in protecting and treating surface water pollution,this article elaborates on the specific operational methods of physical treatment technology,chemical treatment technology,and biological treatment technology from the perspective of research status.It also clarifies how to choose manganese(iron)excess treatment technology based on actual situations,and proposes suggestions from the policy and technical levels for the combination of current situation and treatment technology.It also looks forward to future research directions,pointing out the significance and impact of manganese(iron)excess treatment technology research on rural water supply and environmental protection.
