目的:通过区域供水与分散集中式供水优劣比较,为今后继续做好农村饮水安全工程提供依据。目的:对该区2011~2013年122家供水单位,202个监测点所采集1032份水样监测结果进行对比分析。结果:该区2011~2013年水样合格率分别为54.73%、75.64%、88.84%,项次合格率分别为95.84%、97.45%、99.31%,微生物指标合格率分别为94.37%、98.21%、98.80%,差异均有显著性,且2013年三项指标合格率均明显提高。结论:区域供水大大好于分散集中式供水水质,实行区域供水可以基本保证农村居民喝上放心安全饮用水。
Objective: To compare the advantages and disadvantages of regional water supply and decentralized centralized water supply, and provide the basis for continuing to do well the rural drinking water safety project in the future. OBJECTIVE: To compare and analyze the monitoring results of 1032 water samples collected by 122 water supply units and 202 monitoring points from 2011 to 2013 in this area. Results: The passing rates of water samples from 2011 to 2013 were 54.73%, 75.64% and 88.84%, respectively. The passing rates of the items were 95.84%, 97.45% and 99.31% respectively. The pass rates of microbial indicators were 94.37% and 98.21% 98.80% respectively. All the differences were significant, and the passing rates of the three indicators in 2013 were all significantly improved. Conclusion: Regional water supply is much better than decentralized centralized water supply. The implementation of regional water supply can basically ensure that rural residents can drink safe and safe drinking water.
