2008—2012年钟山县农村饮水安全工程水质监测结果分析

Analysis on Quality of Drinking Water from Rural Drinking Water Safety Project in Zhongshan County in 2008—2012

目的了解钟山县农村饮水安全工程水质卫生状况,为加强农村饮水安全工程建设和管理提供科学依据。方法对2008—2012年钟山县农村饮水安全工程水质监测结果进行统计分析。结果 5年共监测水样500份,合格率为19.20%,各年度水质合格率差异有显著性,呈逐年上升的趋势;感官和一般化学指标合格率为81.0%,毒理指标合格率为100.0%,微生物指标合格率为19.4%;枯水期和丰水期水质合格率差异无显著性;地下水水源明显高于地面水水源水质合格率。结论微生物污染是钟山县农村饮水安全工程水质合格率较低的主要原因。

Objectives To learn the quality of water from the rural drinking water safety project( RDWSP) in Zhongshan County,thus to provide scientific basis for strengthening the construction of RDWSP. Methods Analyzing the data monitored in 2008—2012 for the RDWSP. Results A total of 500 water samples were monitored in five years, with a pass rate of 19. 20%. The pass rate in different years showed an increasing trend. The pass rate for sensory and general chemical index was 81. 0%,for toxicological index was 100. 0%,for microbiological index was 19. 4%. The quality of water between dry and wet season was not significantly different. The quality of underground water was significantly higher than that of surface water. Conclusions Microbial contamination is the main factor affecting the water quality in RDWSP in Zhongshan County.
