目的 掌握我区生活饮用水源水质及变化情况,为改水、管水提供科学依据。方法 按国标“生活饮用水标准检验法”对场区40个生活饮用水源、水质进行10年动态监测与分析。结果 场区生活饮用水源“良好”占42.5％,“可用”的占27.5％,“差”的占30％。存在的主要问题是总硬度、硫酸盐和氯化物超标较严重,分别占所测井数的25％、40％和7.5％;82.5％的水源氟化物含量低于生活饮用水的最低限值0.5mg/L,场区3～10岁儿童龋齿发病率较高。结论 对水源要加强管理,对部分水源水质要进行改造。
Objective To understand the water quality and changes of drinking water source in our district and provide a scientific basis for water diversion and water management. Methods According to the national standard “Standard Test Method of Domestic Drinking Water”, the dynamic monitoring and analysis of 40 drinking water sources and water quality in the field were conducted for 10 years. Results The drinking water sources in the farm area were “good” 42.5%, “available” 27.5% and “poor” 30%. The main problems are the total hardness, sulfate and chloride exceeded the standard, accounting for 25%, 40% and 7.5% of the number of wells; 82.5% of the fluoride in the source of drinking water is lower than the minimum 0.5 mg / L, field 3 to 10-year-old children with higher incidence of dental caries. Conclusion To strengthen the management of water sources, some of the water quality to be transformed.
