2009～2012年钦南区农村饮水安全工程水质监测分析

2009～2012 QinNan district rural drinking water safety engineering water quality monitoring analysis

目的了解钦南区农村饮水安全工程水质卫生状况,为选择安全水源及水处理方式,预防控制饮水性疾病的发生提供科学依据。方法按照《广西农村饮用水卫生监测技术方案》进行实施。结果监测65个农村集中式供水点,检测260份水样,枯水期合格率为49.23%,丰水期合格率为33.08%。细菌总数枯水丰水期合格率分别为89.23%和74.62%;总大肠菌群枯水丰水期合格率分别为96.92%和52.31%;耐热大肠菌群枯水丰水期合格率分别为96.92%和54.62%,枯水丰水期水质监测中以上指标合格率比较,差异有统计学意义(P<0.01)。结论钦南区农村饮水安全工程水质合格率低。影响水质的主要因素是微生物指标超标,有关部门应加强监管。

Objective To understand QinNan rural drinking water safety engineering water quality health status, to select safe water and water treatment water prevention and control the happening of the disease to provide scientific basis. Methods according to the guangxi rural drinking water health monitoring technology scheme of implementation.Results of 65 rural centralized water supply point, detection of 260 water water, 49.23% pass rate, wet season qualified rate 33.08%. The total bacterial count of dry wet season rate were 89.23% and 74.62% respectively; Total coliform is wet season rate were 96.92% and 52.31% respectively; Heat resistant coliform is wet season rate were 96.92% and 54.62% respectively, dry wet season in water quality monitoring above indicators qualified rate comparison, the difference was statistically significant （P〈0.01）. Conclusion QinNan rural drinking water safety engineering quality qualified rate is low. The main factors affect water quality is microbiology indicators overweight, and relevant departments should strengthen the supervision.
