摘　　要：利用城市再生水补给地下水是扩大地下水资源存储量、缓解水资源短缺的有效解决途径。该文通过土壤柱模拟组合式强化井灌系统,并协同臭氧氧化工艺针对城市再生水补给地下水进行研究。实验结果表明:该系统对化学需氧量(COD)的去除率为53%,对UV254的去除率为59%,对磷有较好的固定作用。土壤优先去除易生物降解、非芳香族特征的有机物。臭氧氧化可以改变再生水中有机物的分子结构,提高再生水的可同化有机碳(AOC)值,促进后续土壤对有机物的降解作用。Water shortages are creating a need for artificial groundwater recharge with reclaimed water to supplement the natural water availability. A soil treatment system with ozonation as the treatment of reclaimed water simulated enhanced derect injection well recharge system. This system is shown to remove 53% of the chemical oxygen demand （COD） and 59% of the UV254. Non-aromatic biodegradable organic substances are removed in lab-scale experiments. The soil effectively adsorbs the phosphates while ozonation increases the assimilable organic carbon （AOC） and changes the molecular structure of the organics to accelerate biodegradation in the soil treatment system.
