图们江、鸭绿江沿岸居民饮用水卫生状况分析

Analysis on drinking water hygiene in coastal areas of Tumen River and Yalu River

目的为了解图们江、鸭绿江沿岸居民饮水卫生状况进行连续监测方法 2010、2012、2014年连续3次修订下发《吉林省边境地区生活饮用水现状调查方案》,对鸭绿江、图们江沿岸9个县(市、区、管委会)距离江边1 km范围内居民饮用水的感官性状、毒理、微生物等方面指标进行检测。结果 2010~2014年共监测水样1 635份,合格513份,总合格率31.38%。集中式供水的水质合格率为31.5%,分散式供水的水质合格率为31.0%,两者的差异无统计学意义(P>0.05)。检测水样的微生物指标检测合格率分别为33.0%,55.5%和40.7%。结论吉林省图们江、鸭绿江沿岸居民生活饮用水中微生物指标超标明显,部分地区氟化物超标。

Objective To supervise the sanitation status of drinking water in the coastal areas of Tumen River and Yalu River in Jilin Province.Methods By the reference of Survey Plan of Drinking Water Status in the Frontier Area of Jilin Province,which has been revised consecutively for 3 times in 2010,2012 and 2014,drinking water samples were collected from coastal villages within 1 km to the rivers in 9 counties and tested by sensory properties,toxicology and microbial index.Results A total of 1635 drinking water samples were tested from 2010 to 2014 and 513 samples were qualified with the qualification rate of 31.38%.The qualified rate of centralized water supply and decentralized water supply were 31.5% and 31.0%,there was no statistically significant difference between them（ P 〉0.05）. The microbial indicators testing qualified rate were 33.0%,55.5% and 40.7%.Conclusion The qualified rate of drinking water in the coastal areas of Tumen River and Yalu River of Jilin Province was low,microbial indicators excess and fluoride is obvious in some areas.
