摘要
2018年9月对苏州吴江区某生活垃圾受控(简易)填埋场整治工程进行土壤及地下水相关指标进行现场采样和实验室分析。通过采样分析发现:该生活垃圾填埋场周边环境土壤中无机物指标铬、铅、镉、砷、汞、铜、锌、镍含量均达到相关标准,土壤中53种挥发性有机物均未检出。地下水中氨氮、耗氧量、1,2-二氯乙烷含量均不符合标准要求。超标的主要原因是该生活垃圾简易填埋场建设期按未规范采取防渗措施,致使渗滤液向场地周边渗漏,污染地下水质。
In September 2018, on-site sampling and laboratory analysis were carried out on soil and groundwater related indicators for a domestic garbage controlled (simple) landfill renovation project in Wujiang District, Suzhou. Through sampling analysis, it was found that the contents of inorganic substances such as chromium, lead, cadmium, arsenic, mercury, copper, zinc and nickel in the soil around the domestic waste landfill reached the relevant standards, and 53 volatile organic compounds in the soil were not detected.. The ammonia nitrogen, oxygen consumption and 1,2-dichloroethane content in groundwater do not meet the standard requirements. The main reason for exceeding the standard is that the anti-seepage measures are adopted according to the unstandardized construction period of the domestic garbage simple landfill, causing the leachate to leak to the surrounding area and pollute the groundwater quality.
