多级臭氧催化氧化深度处理印染废水的研究

Study on Multiple Stages of Ozone Catalytic Oxidation Advanced Treatment of Printing and Dyeing Wastewater

介绍了一种多级臭氧催化深度处理印染废水的工艺。以绍兴某印染集聚区二级生化处理出水为该进水,经气浮预处理后,进入一级臭氧催化氧化,后入生物炭滤池进一步处理,最后再经二级臭氧催化氧化,达到最终出水主要指标COD值小于60 mg/L,为其他臭氧深度处理工艺提供参考。

In this paper,a multi-stage ozone catalytic advanced printing of dyeing and printing wastewater treatment was intruded.The secondary biochemical treatment of the water in dyeing and printing industrial park in Shaoxing as influent,the influential was pretreated with floating process and entered into the first ozone catalytic oxidation,then into the biological carbon filter with further process,at last the wastewater purified with the secondary ozone catalytic oxidation to achieve finally water main index COD value is less than 60 mg/L.The process for other ozone treatment process to provide the reference.
