Abstract

Biochemical tail water of Printing and Dyeing industry is a typical low load and refractory wastewater. Its COD concentration is between 150-200 mg/L. In this pilot study, the effect of lignite-coke and ceramic filter in BAF treatment of dyeing and biochemical tail water 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 bio-film. After several months of continuous lignite-coke BAF pilot operation, the results showed that: when the gas-water volume ratio is 10:1, the hydraulic loading is 0.2m3/m2h,the removal rate of COD beyond 50%, the COD of effluent is below 50 mg/L, the effluent is colorless and it meets requirements of design emissions, it also has a good prospect of engineering application.
