摘　　要：原位化学氧化技术逐渐成为地下水污染风险控制与修复技术中的热点,氧化剂的选择及其投加量是原位化学氧化技术的关键参数之一。本文以地下水中的3&4-甲基苯酚、2,4-二甲基苯酚污染的为研究对象,以双氧水、双氧水+硫酸亚铁、双氧水+臭氧为氧化剂进行室内配比试验研究,最终确定了不同氧化剂的氧化3&4-甲基苯酚、2,4-二甲基苯酚的最佳配比、氧化速率等,为原位化学氧化技术的实施提供技术支持。In situ chemical oxidation technology has gradually become a hot spot in the technology of groundwater pollution risk control and remediation. The selection of oxidant and its dosage are one of the key parameters of the in-situ chemical oxidation technology. In this paper, 3,4-Dimethylphenol phenol and 2,4-Dimethylphenol in groundwater are studied in this paper. The laboratory experiments are conducted with hydrogen peroxide, hydrogen peroxide, ferrous sulfate, hydrogen peroxide and ozone as oxidants. The optimum ratio and oxidation rate of oxidized 3,4-Dimethylphenol phenol and 2,4-Dimethylphenol are determined by different oxidizing agents. It provides technical support for the implementation of in situ chemical oxidation technology.
