目的:对本区近5年来的生活饮用水水质检测结果进行分析及相关因素的讨论,进一步了解本区生活饮用水卫生状况。方法:按照《生活饮用水标准检验方法》(GB/T5750-2006)进行检测。结果:检测水样532份,合格份数为241份,合格率为45.30%。主要超标项目为总硬度、硫酸盐、溶解性总固体、菌落总数、总大肠菌群、耐热大肠菌群。结论:本区生活饮用水水质受自然因素影响较大,供水环境卫生状况亟待改善,以提高生活饮用水水质合格率。
OBJECTIVE: To analyze the test results of drinking water quality in the past 5 years and discuss the related factors so as to further understand the sanitary status of drinking water in this area. Methods: According to “drinking water standard test method” (GB / T5750-2006) for testing. Results: 532 water samples were tested, the number of pass was 241, the pass rate was 45.30%. Major over-standard items for the total hardness, sulfate, total dissolved solids, the total number of colonies, total coliforms, heat-resistant coliforms. Conclusion: The quality of domestic drinking water in this area is greatly affected by natural factors, and the sanitary conditions of water supply and sanitation should be improved urgently so as to improve the passing rate of drinking water quality.
