一起硫化物污染生活饮用水事件的调查分析

Investigation of Outbreaking Sulfide Pollution in Drinking Water

摘要

摘要:
目的调查某企业生活饮用水中硫化物污染原因, 为政府预防控制提供科学依据。
方法采用现场卫生学调查与实验室检测相结合的方法。
结果饮用水中硫化物含量平均值水源水为8.25 mg/L、末梢水为7.78 mg/L, 末梢水超过《生活饮用水卫生标准》(GB 5749-2006) 规定限值(0.02 mg/L)的389倍, 硫化物严重超标。
结论在饮用水源地非法建设污染企业, 破坏水源地植被, 废水、废碴、废气等"三废"物质未经处理直接排放是导致硫化物污染水源的主要原因。要确保企业自备饮用水安全, 必须重视水源地的保护。

Abstract:
Objectives To investigate the reason of the sulfide contamination in the drinking water of a corporate, so as to provide a scientific basis for government control and prevention.
Methods Combine the on-site hygienic investigation and laboratory testing method to find the pollution reason.
Results The mean sulfide concentration in source water was 8.25 mg/L, and the peripheral water was 7.78 mg/L, which is 389 times higher than the standard limits for sulfide (0.02 mg/L).
Conclusions The main causes of sulfide pollution in water sources are as below:① illegal construction of pollution enterprises in the source water areas; ② destruction the vegetation in the source water areas, and ③ direct discharge of waste water, waste slag, waste gas without pre-treatment. In order to ensure the safety of drinking water, it is important to pay more attention to protect the source water areas.
