摘要
为了研究遗留电镀污染场地地下水污染特征及影响因子,并进行溯源分析,以广东某废弃电镀污染场地为例,采集9个地下水样品,检测39项指标以分析电镀污染场地地下水的污染特征及源解析。结果表明,该电镀基地污染场地地下水部分受到了较为严重的污染,主要超标污染物有浊度、pH、总硬度、溶解性总固体、硫酸盐、氯化物、氟化物、亚硝酸盐氮、阴离子表面活性剂、高锰酸盐指数、氨氮、氰化物、总α放射性、锰、铬、镍、铁。不同采样点污染程度和污染种类有所不同,其中各检测指标超标最为严重的是GW6采样点,从污染物来源来看,由于原企业管理不规范、偷排、漏排与管道泄漏等原因,导致地下水受到污染,如GW6采样点附近存在非法排污的电镀企业,GW9位于化粪池附近,因此通过对现场企业管理情况调查,对了解场地污染情况有重要的支持作用。
In order to study the characteristic of groundwater pollution and its influencing factors, and make traceability analysis in plating contaminated sites. With an electroplating contaminated site in Guangdong as an example, the authors collected 9 samples of groundwater, and detected 39 indicators to analyze the pollution characteristics and source of groundwater in plating contaminated site. The results showed that： the groundwater of the plating contaminated sites had received the serious pollution, major pollutants were turbidity, pH, total hardness, total dissolved solids, sulfate, chloride, fluoride, nitrite, anionic surfactants, potassium permanganate index, ammonia, cyanide, total a radioactivity, manganese, chromium, nickel, iron. Different sampling point had different pollution degree and types, in which all test indexes exceeded the standard most serious was GW6. Due to the original enterprise management not standardized of waste-water treatment, pipeline leaks and other reasons, resulting in contamination of groundwater, such as GW6 sampling points for illegal sewage near the electroplating enterprises, GW9 located near septic tanks, thus, on-site survey of corporate management, the understanding of site contamination had an important supporting role.
