摘要
通过对大连市乡镇生活垃圾填埋场周边地下水中22项指标进行检测分析,采用标准指数法、评分法等对地下水质量状况进行评价,采用累计污染负荷比法对地下水污染物进行识别,并给出相关管控建议.结果表明:地下水中耗氧量、总硬度、溶解性总固体等7项污染物有超标现象,超标率在15.4％～38.5％之间;区域综合评分值为4.34,总体水质较差;影响水质的污染物主要有总硬度、溶解性总固体、硫酸盐、氯化物、耗氧量、氨氮、硝酸盐等.
Abstract
Through the detection and analysis of 22 indexes in the groundwater around the domestic waste landfill,the standard index method and F value scoring method were used to evaluate the groundwater quality,and the cumulative pollution load ratio method was used to identify groundwater pollutants,and relevant management and control suggestions were given.The results showed that 7 pollutants in groundwater,such as oxygen consumption,total hardness and total dissolved solids,exceeded the standard,and the rate of exceeding the standard ranged from 15.4％to 38.5％.The regional comprehensive score F value was 4.34,and the overall water quality was poor.The main pollutants affecting water quality are total hardness,total dissolved solids,sulfate,chloride,oxygen consumption,ammonia nitrogen,nitrate nitrogen and so on.
