Research on Adsorption and Biodegradation Effect of Reactive Brilliant Blue KN-R in PACT Process

Adsorption and biodegradation effect of Reactive Brilliant Blue KN-R in PACT process was researched by treatment of simulated dye wastewater.The results showed that PACT process exhibited a better removal efficiency compared with adsorption or activated sludge process.The removal efficiency was the best when powder activated carbon concentration was 200 mg/L in the test of activated carbon adsorption,but different in the PACT process,which was 300 mg/L.Reactive Brilliant Blue KN-R was difficult to degrade by microbiology,the effect of removal efficiency was little when increasing activated sludge concentration,the optimum concentration of activated sludge was 1 500 mg/L.
