水库水质锰含量超标原因初探与对策措施建议

A Preliminary Study on the Causes of Excessive Manganese Content in Reservoir Water and Suggested Countermeasures

摘要: 水库型饮用水水源水质锰异常的情况在全国范围均有发生。区分水源水质超标是由于人类活动影响还是地质环境背景造成则需要根据各个水库所处的地理位置和地质环境、周边的污染源和生物活动等情况进行调查分析。桑那水库作为迪庆藏族自治州香格里拉市城区重要饮用水水源地，近年来水质出现季节性锰异常的现象引起了广泛关注。本文旨在对桑那水库水源地水质锰异常原因进行初步分析的同时，为地质环境高背景导致水质锰含量异常甚至超标的水库型水源地开展调查和制定相应对策措施提供参考。

Abstract: Abnormal manganese content in reservoir-type drinking water sources occurs nationwide. Distinguishing whether excessive water quality is due to human impact or the geological environment requires investigation and analysis based on the location and geological environment of each reservoir, surrounding pollution sources, and biological activity. The Sanna Reservoir, a key drinking water source for the urban area of Shangri-La City in Diqing Tibetan Autonomous Prefecture, has recently attracted widespread attention for its seasonal manganese abnormalities. This paper aims to provide a preliminary analysis of the causes of abnormal manganese content in the Sanna Reservoir water source and to provide a reference for investigating and formulating corresponding countermeasures for reservoir-type water sources where abnormal or even excessive manganese content is caused by a high geological background.
