目的了解滦南县农村生活饮用水安全与水质卫生现状,为改善农村饮用水水质提供科学依据。方法调查滦南县居民供水方式、水源类型、覆盖人口、供水能力等资料,采用分层随机抽样的原则抽取30处农村集中式供水工程为重点调查对象。每调查点按丰水期、枯水期分别采样1次。结果共监测水样120份,合格97份,合格率80.8%。丰水期与枯水期监测结果的合格率分别是70.0%、91.7%,差异有统计学意义,微生物学指标合格率较低是影响水质的主要因素;全县监测人口共39 719人,饮用不合格生活饮用水共17 130人,占监测总人口的43.1%,高于全国农村饮水不安全人口比例(34.3%)。结论滦南县农村饮用水卫生状况较差,微生物污染是滦南县农村饮水的主要卫生问题,除应加强对水源的防护与水质的净化消毒处理外,加强丰水期微生物指标的监测是保障饮用水安全的一种重要手段。
Objective To understand the status quo of drinking water safety and water quality in rural Luannan County and to provide a scientific basis for improving drinking water quality in rural areas. Methods The data of water supply, types of water sources, population coverage and water supply capacity of residents in Luannan County were surveyed. Thirty rural centralized water supply projects were selected as the key survey subjects according to the principle of stratified random sampling. Each survey point by the wet period, dry period were sampled 1 time. Results A total of 120 water samples were monitored and 97 were qualified with a pass rate of 80.8%. The qualified rates of monitoring results during the wet season and the dry season were 70.0% and 91.7%, respectively. The differences were statistically significant and the low pass rate of microbiological indicators was the main factor affecting the water quality. The monitoring population in the county was 39 719 with unqualified drinking A total of 17 130 people live in drinking water, accounting for 43.1% of the total population monitored, which is higher than the proportion of unsafe rural drinking water in the country (34.3%). Conclusion Luannan County drinking water health in rural areas is poor, microbial pollution is Luannan County, rural drinking water is the main health problems, in addition to strengthening the protection of water sources and water purification decontamination, to strengthen the monitoring of microbial indicators during the wet season is to protect Drinking water is an important means of security.
