广西农村寄宿制学校饮用水卫生安全状况分析

Drinking Water Sanitary Safety Analysis at Boarding Schools in Rural Areas,Guangxi

目的了解广西农村寄宿制学校饮用水卫生安全现状,探讨饮用水生物污染与介水传染病流行的关系。方法于2005年对广西3市10县100所农村寄宿制学校饮水卫生和介水疾病进行调查,并利用2006年广西农村饮水卫生监测网络农村学校自备水源供水水质监测数据进行分析。结果广西农村学校饮水水质合格率仅为27.0%,尤其是微生物污染严重;流行病学分析表明饮用水微生物污染与肠道传染病疫情发生有明显相关关系。结论广西农村寄宿制学校饮水微生物污染严重,是介水传染病爆发疫情在学校高发的主要原因。

Objective To understand the eurrent sanitary status of drinking water at boarding schools in rural areas in Guangxi and to explore the correlation between mierobiologie contamination in drinking water and water-borne infectious diseases. Methods A survey on drinking water safety and water-borne diseases was conducted at 100 boarding schools in 10 counties of 3 cities in 2005. Water supply data at those schools were obtained from the 2006 Guangxi rural drinking water safety monitoring network. Results Less than 30% rural schools＇drinking water met the national standards, particularly the indicator of microbial contaminants. Further study showed that mierobial contamination in drinking water was significantly correlative to the occurrence of enteric infectious diseases. Conclusion Serious microbial contamination in water supply is the major cause for the high incidence of water-borne diseases in rural schools.
