| 摘 要： | 以广东珠海某电镀行业企业发生柴油泄漏事件为例，采用异位修复抽提处置技术处理污染地下水，表面淋洗工艺处理污染土壤。泄漏点开挖区设置9个喷头，洒水量为1.3 m3/h，喷淋时间为2 h/d，泄漏点西面绿化带设置5个喷头，洒水量为0.7 m3/h，喷淋时间为9 h/d，淋洗水进入地下水后抽取至厂区污水厂处理，治理历时9个月，地下水石油类浓度降至0.3 mg/L以下，达到GB 5749—2006《生活饮用水卫生标准》中石油类标准限值。

| Abstract: | Taking the real case of diesel leakage in an electroplating enterprise in Zhuhai, Guangdong Province as the example, the ectopic repair extraction technology was used to treat the contaminated groundwater, and the surface leaching process was used to treat the contaminated soil. In this study, nine nozzles were set up in the excavation area of the leaking point, with the sprinkling water rate of 1.3 m3/h, and the spraying duration of 2 h/d. There were 5 nozzles in the western green belt of the leakage point, with the sprinkling water rate of 0.7 m3/h, and spraying duration of 9 h/d. The leaching water entered the groundwater and was then pumped to the sewage treatment plant for later treatment. After 9 months, treatment, the final concentration of petroleum in groundwater was lower than 0.3 mg/L, reaching the limit of petroleum in the Sanitary Standard for Drinking Water (GB 5749—2006). |
