CAF空穴气浮—生物接触氧化工艺在制革废水处理中的应用

APPLICATION OF CAVITATION AIR FLOTATION AND BIOLOGICAL CONTACT OXIDATION IN TREATMENT OF TANNERY WASTEWATER

介绍了一种皮革废水处理新工艺，即ＣＡＦ空穴气浮—接触氧化工艺。经预处理的制革综合污水采用ＣＡＦ系统混凝气浮，生物接触氧化工艺处理后，ＣＯＤＣｒ、ＢＯＤ５、ＴＳＳ、ＦＯＧ、硫化物以及总铬的去除率均在９５％以上，可达到回用标准。

A new wastewater treatment technology of cavitation air flotation and biological contact oxidation technology with application in tannery industry were described in the paper.The pretreated tannery industry comprehensive wastewater,after treated by cavitation air flotation and biological contact oxidation technology,COD Cr ,BOD,TSS,FOG,Sulphides and total Chromium removal efficiencies in excess of 95% can be achieved and meet with the standards for recycling water.
