Abstract

The secondary effluetn of Printing and Dyeing industry wastewater is a typical low load and refractory wastewater. The COD concentration is between 150-200 mg/L. In this pilot study, the treatment effect of lignite-coke and ceramic filter BAF was investigated. By comparison with the laboratory scale test and parameter optimization, lignite-coke filter take obvious advantages on the terms of bleaching and biological biofilm. After several months of continuous lignite-coke BAF pilot operation, the results show that: the removal rate of COD beyond 50% under the condition of volume ratio 10:1 for gas to water, hydraulic loading is 0.2m3/m2h, , the COD concentration of effluent is below 50 mg/L and colorless, can reach the requirements of design. Lignite-coke BAF has a good prospect of industrialized application.
