Abstract

coking tail wastewater is difficult to dispose due to its hard-degradation substance. Biological Aerated Filter (BAF),with a characteristics of strong resistance to organic impact load,is a new way in treating high-concentration organic wastewater.In this paper, coking tail wastewater disposed in two-stage BAF is investigated. It shows that the optimized condition to dispose organic is that temperature is 25 ~ 35 °C, pH is7 ~8, gas-water ratio is 2~3:1, reflux ratio is 0.5~1. Under optimal conditions COD removal rate of the system remains stable around 69.10%.
