摘要
将《农村实施(生活饮用水卫生标准)准则》上的水质分级标准应用于150处农村水源458个水样的调查监测结果,分别采用将最劣项目的级别确定为水样级别,最劣次水样级别确定为水源级别,用加权平均和炬阵相乘的方法,对水样、水源、饮水种类和区域饮水状况进行了级别评定,结果表明:Ⅰ级水样占9.6％,Ⅱ级9.39％、Ⅲ级11.5％,级外69.43％。简易自来水的平均级别为3.2级、手压井3.4级,大口井3.9级,本地饮水状况为3.3级。分析表明,目前影响水质级别的主要因素为细菌学指标,占68.67％,去除该因素的限制后,可使区域饮水状况提高1.4级,达到1.9级。
The grading criterion for water quality from 'Criterion of hygienic standard for life's drinking water performed in rural area' was applied to the investigating and monitering results of 458 water samples from 150 rural sources of water.The methods for defining the grade of the worst item as the water source grade,the grade of the worst water sample as the water grade,and weighted average and matrix were used to evaluate the grade of water sample,source of water,kind of drinking water and regional drinking water condition.The result indicated that Grade Ⅰ water sample made up 9.6%,Grade Ⅱ,9.39%,Grade Ⅲ,11.5%;subgrade, 69.43%.The average grade of the simple tap water was 3.2 grade ;hand-press well,3.4 grade;big-opening well,3.9 grade;the drinking water condition in this area was 3.3 grade.Our analysis indicated that the main factor influencing at present the water quality grade of the bacteriological index,which accounts for 68.67%.After removing the re-striction from this factor,the regional drinking water condition,which may be raised by 1.4 grade,can reach 1.9 grade.
