目的 :了解吕梁地区城镇集中式供水卫生现状。方法 :对吕梁地区城镇市政集中式供水卫生进行调查。结果 :全区 13个市政集中式供水单位仅 3个实行饮水消毒 ,其余均不消毒 ,所查水源 30米范围内有生活污染源的占 2 7.5 9% ;10 0米范围有污水灌田占 10 .35 % ;10 0米范围有农田使用化肥占 44 .83% ;10 0 0米范围有工业污染源占 2 4.14%。水质监测 ,一级水占 34.88% ,三级和低于三级水占 33.72 % ,枯水期优于丰水期 (P<0 .0 5 ) ,限制水质级别的因素主要是细菌学指标。结论 :提示我区城镇集中式供水面临的问题主要是饮水消毒 ,其次是水源卫生防护。
Objective: To understand the current status of centralized water supply and sanitation in urban areas in Luliang. Methods: To investigate the municipal centralized water supply hygiene in Luliang district. Results: Only 3 municipal centralized water supply units in the region implemented drinking water disinfection, the rest were not disinfected, the source of living pollution within 30 meters of surveyed water sources accounted for 2 7.59%; 10 0 meters of sewage irrigation fields accounted for 10 .35%; there is 44.83% of the farmland fertilizer is used in the range of 10 meters; industrial pollution sources account for 2 4.14% in the range of 100 meters. Water quality monitoring accounted for 34.88% of Grade I water, 33.72% of Grade III and III water, and better than the wet season in the dry season (P <0.05). The main factors restricting water quality were bacteriological indicators. Conclusion: It is suggested that the problems of centralized water supply in urban areas in our district are mainly water disinfection, followed by water sanitation protection.
