摘要
目的了解合浦县农村饮用水卫生状况,为改善农村饮用水水质提供科学依据。方法 2014年-2016年对合浦县县城和12个乡镇的农村集中性供水进行丰水期和枯水期的出厂水和末梢水采样,按相关国家标准进行检测和评价。结果 2014年-2016年共采集408份水样,其中合格水样234份,总合格率为57%,理化指标和微生物指标3年总合格率分别为62%和85%,差异均有统计学意义(χ~2=44.58;χ~2=29.18;χ~2=16.66,P均<0.01)。其中pH值超标率为28%,铝超标率为12%,菌落总数超标率为11%,总大肠菌群超标率为5%。结论合浦县农村水水质虽然合格率逐年上升,但总体合格率不高,pH值、铝、菌落总数、总大肠菌群超标比较严重,应引起有关部门高度重视。建议改善水质净化和消毒技术,加强水管网的维护和改造,保证饮用水安全。
Objective To understand the hygienic status of the rural drinking water in Hepu county, so as to provide scientific basis for improving rural drinking water quality. Methods During the dry season and rain season from 2014 to 2016, the sam- pies of chlorinated water and peripheral water were collected from 12 township rural centralized water waterworks, and then de- tected and evaluated according to the relevant national standards. Results During 2014 - 2016, a total of 408 water samples were collected, 234 were qualified and the total pass rate was 57%. The total qualified rate for physical -chemical indexes and microbiological indexes were 62% and 85%, respectively. The differences were statistically significant （X2 = 44.58, X2 = 29.18, X2 = 16.66, P 〈0.01 ）. Among them, the overrate of pH was 28%, the overrate of aluminum was 12%, the total num- ber of colonies was 11%, and the total coliforms was 5%. Conclusion The rural drinking water quality in Hepu county is im- proved year by year, but the overall qualified rate is not high, and the indicators seriously over standard mainly focus on pH, aluminum, the total number of colonies, and total coliforms. The relevant departments should pay more attention to the rural drinking water quality. It is suggested to improve water purification and disinfection technology, strengthen the maintenance and reconstruction of water supply pipe to ensure the safety of drinking water.
