臭氧氧化法处理感光废水中COD的研究

A study on the determination method for the removal of COD by ozone degradation in the treatment of development waste-water

考察臭氧氧化法处理感光废水过程中反应时间、反应温度、原水稀释倍数、初始pH值、臭氧通入量等因素对COD去除率的影响。在优化条件下,显影废水中COD去除率为61.6%、定影废水中COD去除率为72.6%。

Influence factors on the removal rate of COD in the treatment of the development waste-water for photographic industry by oxidation of ozone,such as reaction time,reaction temperature,dilution times of raw water,initial pH value,and feed volume of ozone,were evaluated through experiments.Optimal conditions were given by orthogonal experiment and economical analysis.Under the conditions the development waste-water was treated to remove 61.6% COD,and the effluent from fixing to remove 72.6% COD.
