Effect of Phenol on Treatment of Sewage from Channel Discharge with Biological Accelerator-Biofilm Process

Abstract:

The research studied enhanced treatment of sewage from discharging points of rivers by biofilm process dosing with enzyme and the effect of phenol on removal rates of the main pollution indexes, and investigated promotion effect of enzyme (including the laboratory developed compounded enzyme and the foreign composite enzyme) on treatment of sewage by biofilm process. The research results indicated that when initial concentration of phenol was 5mg/L, the removal rates of phenol, COD_Cr and ammonia nitrogen obviously decreased compared to no phenol added to reactor A, B and C, and the negative effect of phenol was smaller on reactor B and C than on reactor A. Moreover, enzyme had good promotion effect on biofilm process during the sewage treatment process.
