臭氧—曝气生物滤池处理难生物降解废水的试验研究进展

Progress of Experimental Research on Refractory Wastewater Treating by Using Biological Filter of Ozone and Aeration

臭氧与曝气生物滤池组合工艺,可提高难生物降解废水的处理效率。文章综述了该组合工艺在不同行业难生物降解废水处理中色度、COD去除率等方面的研究进展,表明组合工艺对不同原水的处理效果明显。指出臭氧与曝气生物滤池组合工艺作为一种深度处理工艺是非常适合我国国情的水处理技术,尤其对我国今后中水回用、企业污水闭路循环以及"零排放"具有重要意义,应加大研发和开发力度,推广其应用。

The combined process of biological filter of ozone and aeration could imporve the treating efficiency of refractory wastewater.The research progresses in colour,COD removal ratio and other aspects of refractory wastewater treating in different industries by using this combined process are reviewed here in detail.At the same time,it is indicated that the combined process has obvious effect in the treatment of different water,it is an advanced water treating technique which is suitable to conditions in China,especially it is of significance to be used for water reusing,closed sewage cycling and zero discharge in the future.So,more studies and development for it should be made to expand its application.
