摘要
目的了解嵊州市剡溪沿岸井水水质现状及影响因素,为保护、管理和利用井水资源提供科学依据。方法选择嵊州市剡溪沿岸10个村进行井水监测和用水情况调查,评价方法采用单因子指数评价法和国标F值法。结果嵊州市剡溪沿岸部分井水综合评价F值均小于2.5,整体水质较好,但总大肠菌群、菌落总数和锰超标严重,最高值分别超标532.3、45和10.3倍;井水利用率为45.18%,有10%的家庭作为饮用水。结论嵊州市剡溪沿岸部分井水受到一定程度污染,建议剡溪沿岸居民饮用消毒处理用水。
Objective To know the quality of well water along the banks of Shan River and its influencing factors. Methods The quality and utility of well water of 10 villages along the river was monitored, meanwhile, the water quality was assessed by the method of single - factor index evaluation and international standard F value. Results The overall quality of well water along Shan Rive was good （ F 〈 2.5 ）, while the index of COLI, total bacterial count and manganese exceeded the standard. The highest values are 532.3,45 and 10.3 times respectively. The utilization rate of well water was 45.18%, in which 10% used as drinking water. Conclusion The well water along Shan river is contaminated partly, suggesting it should be replaced by disinfected water for safety.
