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。
The use of municipal reclaimed water to recharge groundwater is an effective way to expand the storage of groundwater resources and alleviate the shortage of water resources. In this paper, a combination of soil column simulation enhanced well irrigation system, and in conjunction with ozone oxidation process for urban reclaimed water supply groundwater research. The experimental results show that the removal rate of chemical oxygen demand (COD) of the system is 53%, the removal rate of UV254 is 59%, and the system has a good fixation effect on phosphorus. Soil priority to remove biodegradable, non-aromatic characteristics of organic matter. Ozonation can change the molecular structure of organic matter in reclaimed water, increase the assimilable organic carbon (AOC) of reclaimed water, and promote the degradation of organic matter by subsequent soil.
