摘要
目的通过对三台县生活饮水水质现状调查,为政府制定饮水卫生政策提供科学依据。方法分散式供水按镇(乡)行政村数2∶1比例随机抽1份水样,自备集中式供水、集中式供水定期卫生监测,按照生活饮用水标准检验方法GB 5750-2006进行检测,检测结果按照生活饮用水卫生标准GB 5749-2006进行评价。结果不同水源类型饮水人数浅井水为44.05%,深井水为29.10%,江河水为13.67%,山泉水(简水)为11.83%,溪水为0.60%,水库水为0.57%。不同供水方式水质合格率集中式供水为56.00%,集中式供水(以地面水为水源)为62.16%,自建集中式供水为68.96%,机器取水为43.33%,人力取水为32.297%,手压泵取水为64.912%,山泉水(简水)为48.837%,不同供水方式合格率之间差异有统计意义(P<0.01)。深层地下水、浅层地下水合格率之间差异有统计意义(P<0.01)。结论三台县生活饮用水水源以浅层、深层地下水为主,供水方式分散式为主,水质不合格项目主要为微生物污染。建议政府进行饮水卫生知识长效性的公益宣传,加大监督管理和技术指导力度,提高水质合格率。
[Objective ] To provide the scientific basis for government to formulate health policy in drinking water through the investigation about the present water quality of Santai County. [Methods] Water samples were collected randomly from decentralized water supplying, according to the ratio of the administrative villages numbers to samples 2：1. Regular health monitoring was conducted on centralized water supply of self-buih and centralized water supply. The test was based on the drinking water standard test method GB 5750-2006, and the results were evaluated by the drinking water sanitary standard GB 5749-2006.[Results] The percentage of drinking water from different types of water source were shallow wells 44.05%, deep wells 29.10%, river waters 13.67%, mountain spring 11.83%, stream 0.60%, reservoirs water 0.57%. Water qualified rate was 56.00% of centralized water supply, 62.16% of centralized water supply （water on surface）, centralized water supply of self-built 68.96%, water supply by equipment 43.33%, water supply by man 32.297%, water supply by hand pump 64.912%, and mountain spring 48.837%. The water quality was significantly different between different types of water source （P〈0.01）. The water quality was also significantly different between deep groundwater and shallow groundwater （P〈0.01）. [Conclusion] The main drinking water sources of Santai County are shallow and deep groundwater and decentralized water supply. The main unqualified item of water is microbial contamination. It is suggested that the relevant department should carry out publicity about the health knowledge of drinking water, enhance management and technical guidance, so as to improve water qualified rate.
