摘　　要：目的:调查居民生活饮用水发生黑黄色沉淀物、泥土腥臭味的原因,以采取相应处理措施。方法:采用流行病调查方法对污染情况进行调查,实验室对水源水、出厂水、未稍水按照国家地表水环境质量标准、生活饮用水标准进行检验和评价。结果:源水1符合国家生活饮用水源水相关卫生标准要求,源水2铁、锰、总大肠菌群,出厂水锰、总大肠菌群、菌落总数,未稍水铁、总大肠菌群、菌落总数不符合国家相关卫生标准要求,锰超过标准最高15倍,总大肠菌群超过测定限值。结论:该水厂采用水库底层水为源水,底层污染物不断的累加,秋未季节,气温变化产生逆温层,使水体污染,企业管理不规范,监督机制不健全,造成此次污染事件的发生,采取措施后未再发生类似事件。Objective：To investigate the causes of tawny precipitate and earthy odour in drinking water,and adopt corresponding measures for improvement.Methods： Epidemiological investigation was carried out to investigate the pollution condition,source waters,produced waters and terminal waters were tested and evaluated in accordance with the environmental quality standards for surface water and the standard for drinking water quality by lab.Results： Source water 1 met national correlative health standards,while the terms such as Fe,Mn and total coliforms of source water 2,Mn,total coliforms,total bacterial count of produced waters,Fe,total coliforms,total bacterial count of terminal waters didn′t met national correlative health standards.Mn was 15 times over the standard,the total coliforms also exceeded test limit.Conclusion： The bottom water of the reservoir was used as source water in water works,and with the accumulation of bottom pollutants,inversion layer was produced by climate change in late autumn season,so the water was polluted.In addition,the nonstandard management and incomplete supervision mechanism also result in the occurrence of the pollution.However,pollution of this kind no longer happen after some control measures.
