摘要
为查明济南西部岩溶地下水有机物污染现状及原因,通过统计分析区内100件地下水有机物含量测试结果,有卤代烃、单环芳烃、氯代苯类、有机氯农药4类有机物检出;检出个数最多的为三氯甲烷和三氯乙烯,均为卤代烃;但检出值普遍偏低,远小于《生活饮用水卫生标准》(GB5749-2006)的标准限值,表明:研究区地下水存在有机污染,但污染度较低。污水排放和垃圾堆渗透液是造成地下水有机污染的主要来源。
In order to find out kast groundwater organic contamination,through statistics and analysis on organic matter content test results gained from 100 groundwater samples in study area,4 organic matters,such as haloalkane,aromatichydrocarbon,chlorobenzene and organochloride have been found out. The maximum number of detection is chloroform and trichloroethylene. They both belong to haloalkane,but the test value is very low and is much lower than ＂ Standards for Drinking Water Quality ＂（ GB5749-2006） standard limits. It is showed that groundwater has been contaminated,but is much lower than drinking water quality limits. The pollution degree is low. The high value of groundwater organic content has close relation with sewage discharge and waste discharge.
