| 摘 要： | 通过试验研究了臭氧氧化对城市二级处理水中有机物特性的影响。结果表明,适当的条件下臭氧氧化可提高水的可生化性,不同接触时间水中有机物的分子量分布特征不同;臭氧对水中有机物的氧化过程分为3个阶段,均属于一级反应,并得出了相应的动力学方程。利用上述结果,选择适当的控制条件,为臭氧预氧化与不同型式膜组合实现城市污水的高效低耗的再生利用提供一定的理论依据。

| Abstract: | A study on ozonization of secondary effluent was conducted with different retention time, and the organics presented different molecular size distribution characteristics, which provided a theoretical basis for choosing the right process of ozone combination.The results showed that ozonization raised the biodegradability of organics, which could be divided into three phases, each of which was the first order reaction,then the dynamic equation of ozonization of secondary effluent could be obtained, which provided theoretical proof for choosing the appropriate ozone retention time, and realizing high efficiency and low energy consumption treatment of municipal wastewater. |
