湖北省农村供水水质调查

了解湖北省农村饮用水水质「方法」对湖北省４个县共４７个农村供水点「地面水１０个（集中式供水８个,分散式供水２个）,地下水３７个（集中式供水２４个,分散供水１３个）」水质进行了监测,根据《农村实施（生活饮用水卫生标准）准》进行评价。「结果部分以地面水为水源的水厂季节性投加消毒剂,大部分以地水为水源的水厂全年未投加消毒剂。

Investigation on Drinking Water Quality in Rural Areas of Hubei Province

Objective]To find out the drinking water quality in rural areas of Hubei province [Methods]The sanitary qualities of water samples collected from 47 sampling locations,including 10 surface water locations (8 centralized water supply locations,2 decentralized water supply locations) and 37 underground water locations (24 centralized water supply locations,13 deentralized water supply locations), in 4 counties of Hubei province were monitored,and were assessed according to the criteria of Sanitary satndard for Drinking Water enforced in rural areas [Results]Seasonal water sterilization was carried out in partial water plants collected from surface water sources ,no water sterilization was carried out in most of the water plants collected from underground water sources in the whole year.The main sanitary problem of centralized water supply system was that the bacteriological indexes exceeded the sanitary standards.In planty water period and low water period,none of the water samples of decentralized water supply system collected from surface water sources were qualified,about 37.5% and 50% of water samples of centralized water supply system didn't meet the sanitary standard for drinking water as three class Among the water supply locations collected from underground water sources ,the qualified rates of water samples of decentralized water supply system (mainly including hand pump wells) revealed no significant differences compared with those of centralized water supply system in planty water period,and were higher than those of centralized water supply system in low water period [Conclusion]If the underground water sources presented good sanitary quality,the effects of water improvement induced by establishing hand pump wells were similar to those induced by establishing water treatment plants in rural areas without well developed economye
