  • 摘要: 为了保障再生水水质生物稳定性，控制再生水在储存、输配和利用过程中微生物生长，对再生水臭氧氧化处理工艺水质生物稳定性进行了研究。研究发现，臭氧氧化对再生水厂二级出水的溶解性有机碳（DOC）去除效果有限，对UV254和荧光强度有较好的去除效果，但可导致水样AOC水平升高，水质生物稳定性降低。分析臭氧氧化后不同有机物组分的变化情况，发现臭氧氧化对分子量为0.5~20 kDa有机物有较好的去除效果，而分子量小于0.5 kDa有机物没有明显变化。
    Abstract: In order to protect the biological stability of reclaimed water and control the risk of microbial growth during storage, transportation, and utilization of reclaimed water, this paper reported on the biological stability of reclaimed water in the ozone oxidation process. It was found that ozonation had limited effect on the removal of dissolved organic carbon (DOC), but had significantly better effect on the reduction of UV254 and fluorescence intensity. However, ozonation increased the level of assimilable organic carbon (AOC), thus decreasing the biological stability of the reclaimed water. The change in the different components of organic matter after ozonation was analyzed. The results indicated that ozonation process efficiently removed organics with molecular weight of 0.5-20 kDa, but no significant change was detected for organics with molecular weight less than 0.5 kDa.
