目的采用单因子和综合指数法对嵊州市农村水源水水质进行评价,通过分析水质监测数据,判定嵊州农村饮用水水质类别。方法选择嵊州市2011-2015年以地表水为水源的监测点,共采集水样240份(2011年39份,2012年46份,2013年50份,2014年53份,2015年51份),对主要污染物指标进行测定,计算单因子和综合指数,评价水质类别。结果嵊州市2011-2015年农村水源水水质良好,水质综合污染指数均小于0.8,等级为合格。不合格项目为浑浊度、锌及菌落总数。结论嵊州市农村饮用水水质优良,水源地可长期作为生活保障用水,但随着经济发展及空气污染的加重,有关部门应进一步加强对水源地的保护和水源水水质卫生监督。
Objective To evaluate the water quality of rural water sources in Shengzhou by single factor and comprehensive index method, and to determine the quality of drinking water in Shengzhou rural areas by analyzing the water quality monitoring data. Methods A total of 240 water samples were collected from Shengzhou City in 2011-2015 (39 in 2011, 46 in 2012, 50 in 2013, 53 in 2014 and 51 in 2015) The main pollutants indicators were measured, calculated single factor and composite index, evaluation of water quality categories. Results The water quality of rural water source in Shengzhou was good from 2011 to 2015, and the integrated water pollution index was less than 0.8 and the grade was qualified. Unqualified items for the turbidity, zinc and the total number of colonies. Conclusion The water quality of rural drinking water in Shengzhou is good, and the water source can be used as water for living protection for a long time. However, with economic development and air pollution aggravating, relevant departments should further strengthen the protection of water sources and sanitation supervision of water and source water quality.
