摘要
目的掌握福建省农村饮用水现况,为各级政府决策提供科学依据。方法按比例分层随机选择水质调查(监测)点,采集集中式供水末梢水和分散式供水储水器水进行检验。结果我省农村集中式供水占51.29%,分散式供水占48.71%;集中式供水水源以水库为主,占38.06%;分散式供水以浅井为主,占49.49%;以地面水为水源占41.4%,以地下水为水源占58.6%。全年水质监测合格率为54.8%,其中丰水期合格率53.2%,枯水期合格率56.5%;集中式供水合格率61.7%,分散式供水合格率44.0%;以地面水为水源的水质合格率59.4%,地下水为水源的水质合格率51.1%;总大肠菌群合格率69.8%,细菌总数合格率85.6%。结论我省近50%农村人口为分散式供水,改水任务十分艰巨;饮用水质合格率低,微生物超标为主因。
Objective To realize the status of drinking water in rural of Fujian.Methods Drinking water sites were stratified and sampled randomly,and water from both the end of centralized and decentralized water supply locations were tested.Results In rural of Fujian,51.29% of drinking water were supplied by centralized water supply system,and 48.41% by decentralized water supply system.Reservoirs were the main sources of centralized water supply（38.06%）,while shallow wells were the main sources of decentralized water supply（49.49%）.41.4% of drinking water were collected from surface water locations,and 58.6% from underground water locations.The qualified rates of water samples were 54.8% during the year,53.2% during plenty water period and 56.5% during low water period,respectively.The qualified rates were 61.7% for centralized water and 44.0% for decentralized water;59.4% for surface water and 51.1% for underground water respectively.Among all water samples,69.8% met the standard of total coliform and 85.6% were qualified for total bacteria.Conclusion Nearly half of rural population in Fujian are supplied with decentralized water which has a low qualified rate mainly due to microoganic contaminant.The technical guidance for rural water supply in Fujian should be improved.
