洛阳市农村集中式供水水质监测结果分析

目的：了解洛阳市农村集中式供水水质状况，探讨有效防治措施，为改善农村集中式供水饮水安全提供依据。方法：按照国家有关水质检验标准对2012年洛阳市9个县（市）250处农村集中式供水点的饮用水水质进行监测，统计分析不同条件对水质指标的影响。结果：抽检500份农村集中式供水出厂水水样合格率为39.80%，500份末梢水水样合格率为38.00%。不同水处理工艺、不同水源类型的集中式供水水质指标比较差异有统计学意义（P〈0.01）；枯水期水质指标合格率高于丰水期（P〈0.01）。结论：农村集中式供水水质指标合格率与集中式供水水处理工艺、水源类型等多种因素有关，提示要加强农村集中式供水管理，完善水质净化处理工艺，加大水源保护力度，同时加强农村饮水安全宣传，提高农民健康意识。

Analysis on Water Quality Monitoring Results of Centralized Water Supply in Rural Areas of Luoyang City

Objective： To investigate the health situation of centralized water supply in rural areas and discuss efficient preventive measures,so as to provide a basis for the improvement of water quality of rural centralized water supply.Method：The drinking water quality of 250 centralized water supply points in rural areas of 9 counties in Luoyang City in 2012 were monitored according to the relevant national standards of water quality testing. The water quality indicators of samples in different conditions were analyzed statistically.Result：In the 500 detected finished water samples of centralized water supply in rural areas,the total qualification rate was 39.80%.In the 500 detected peripheral water samples of centralized water supply in rural areas,the total qualification rate was 38.00%. The water quality indicators showed statistically significant difference among centralized water supplies with different water treatment processes as well as various water source types（P〈0.01）.The water quality in the dry season was better than that in the wet season（P〈0.01）. Conclusion：The total qualification rate of centralized water supply in rural areas is related to the factors like water treatment processes and water source types. It suggests that to strengthen management of centralized water supply in rural areas,water treatment processes should be integrated,water source protection should be promoted,and the propaganda on rural drinking water safety should be strengthened,to improve the health awareness of peasants.
