目的调查了解2011年武鸣县集中式供水单位现状及其水质卫生状况,为改进制水工艺,提高饮水质量和为武鸣县各级政府部门决策提供科学依据。方法通过对集中式供水单位进行卫生监督检查,采集各单位的出厂水和末梢水进行检验,采用描述性流行病学方法进行统计学分析。结果全县共有集中式供水单位40家,水源以地下水为主,占90.00%,15家有完善的水源防护设施,25家水源防护设施不完善;饮用水水质监测结果总合格率为48.86%,微生物指标超标率为50.00%,感官性状指标超标率为7.95%,一般化学指标超标率1.14%,毒理学指标全部合格。结论 2011年武鸣县集中式供水水质合格率较低,以微生物指标超标为主,应加强水源防护工作。
Objective To investigate and understand the status quo of Wuming County centralized water supply units in 2011 and the status of their water quality and hygiene, in order to improve water technology, improve drinking water quality and provide scientific basis for decision making of government departments at all levels in Wuming County. Methods Through the health supervision and inspection of centralized water supply units, the ex-factory water and the peripheral water of all units were collected and tested, and the descriptive epidemiological methods were used for statistical analysis. Results There were 40 centralized water supply units in the county, with groundwater mainly accounting for 90.00%, 15 well-equipped water protection facilities and 25 imperfect water protection facilities. The total qualified rate of drinking water quality monitoring was 48.86% The rate of exceeding the standard of microorganism was 50.00%, the rate of exceeding the standard of sensory traits was 7.95%, the rate of exceeding the standard of general chemical indicators was 1.14%, and all toxicological indicators were qualified. Conclusion Wuming County centralized water quality in 2011 qualified rate is low, the main indicators of excessive microbial, water protection should be strengthened.
