摘要
目的为了解百色市农村生活饮用水卫生现况,对农村介水传染病发生和流行风险进行预测和预警。方法按水源类型、供水规模、水处理方式和覆盖人口等进行分层,按分层随机抽样的方法抽取百色市12县(区)范围内有代表性的农村集中式供水工程209座、分散式供水取水点80个进行水质卫生状况调查,分别在枯水期(3月)和丰水期(7-8月)各采样监测1次。结果百色市农村生活饮用水以集中式供水为主,占总人口的56.05%;水源类型以地表水为主,占74.94%;生活饮用水综合合格率低,为19.71%,集中式供水出厂水合格率为21.05%,在检测的19项指标中,合格率较低的是总大肠菌群、耐热大肠菌群,分别为29.37%、43.00%。结论百色市农村生活饮用水水质合格率低,主要是受到粪便和生活污水污染严重,存在介水传染病发生和流行的风险。
Objectives To understand the quality of drinking water and to conduct prediction and early warning for the occurrence and prevalence of water-born infectious sickness in rural areas of Baise. Methods A total of 209 representatives centralized water supply projects and 80 decentralized water supply facilities in 12 counties of Baise city were selected according to the types of water source, the scale of water supply, the ways for water treatment and population coverage and so on by stratified random sampling method. The quality of water samples collected in dry season （March） and wet period （July-August） was monitored. Results The main type of drinking water supply in rural area was centralized, covering 56. 05% of total population. The main type of water source was surface water accounting for 74. 94%, and 26.42% of which was from stream water. The comprehensive drinking water qualified rate was only 19. 71%. The qualified rate of treated water from the outlet of centralized water supplies was 21.05%. For the 19 detected indicators, the qualified rate for total coliforms （29. 37% ） and heat -resistant coliform bacteria （43.00%） were low. Conclusions The supply of drinking water in rural area was contaminated seriously by manure and sewage, and the water quality was low. There was a risk of spreading water - borne diseases in this area.
