徐闻县垃圾场是湛江市地下水环境质量监测网的一环。采用水文地质学及地下水动力学的理论与方法分析徐闻县垃圾场水文地质特征,对垃圾填埋场及周边地下水污染以及土壤污染进行分析评估。对地下水环境问题及成因进行分析探讨,明确了该地区包气带介质透水性良好,中浅层地下水水质量均以Ⅳ类为主,周边的土壤类别为Ⅲ类土。建议对该地区进行持续的地下水监测工作,建立动态监测网络及规范垃圾场管理。
Xuwen County garbage dump is Zhanjiang City groundwater environmental quality monitoring network. Hydrogeology and groundwater dynamics theories and methods were used to analyze the hydrogeological features of the landfill in Xuwen County. The landfill and surrounding groundwater pollution and soil pollution were analyzed and evaluated. The problems and causes of groundwater environment are analyzed and discussed. It is clear that the medium of aeration zone in this area is good in water permeability. The water quality of groundwater in middle and shallow layers is mainly Ⅳ, and the surrounding soil is Ⅲ. It is advisable to conduct continuous groundwater monitoring in the area, establish a dynamic monitoring network and regulate the management of landfills.
