摘要
试验研究了Mn(Ⅱ)催化KMnO4氧化、臭氧氧化、O3/UV组合工艺对城市二级处理水中有机物氧化分解的影响,并对它们的效果进行了对比。结果表明,适当的条件下Mn(Ⅱ)催化KMnO4氧化、臭氧氧化、O3/UV组合工艺均可提高水的可生化性,并且对水中的UV254也有不同程度的去除效果。O3/UV组合工艺在提高可生化性和UV254去除中为最优。利用上述结果,选择适当的控制条件,为预氧化与不同工艺结合以实现城市污水的高效低耗再生利用提供一定的理论依据。
Catalytic effect of Mn （ Ⅱ ） on oxidation of water by potassium permanganate-ozone-O3/UV combined process which influence the oxidative decomposition of organic compounds in the secondary treated wastewater was studied. Results showed that catalytic effect of Mn（ Ⅱ ） on oxidation of water by potassium permanganate, ozone, O3/UV combined process can improve biodegradability of the secondary treated wastewater under appropriate conditions, and have different influence on removal effect on UV254. O3/UV combined process is optimal in improvement of biodegradability and the removal of UV254 in the above mentioned oxidation technology. The results can provided theoretical proof for choosing the appropriate pre-oxidation which can combine with other process to realize high efficiency and low energy consumption reclamation and reuse of municipal wastewater under appropriate control conditions.
