Study on Treatment of Sewage from Channel Discharge with Biological Accelerator-Biofilm Process
This paper studied treatment of sewage from channel discharge with biological accelerator-biofilm process, and investigated the promoting effect of biological accelerator on biofilm process during the sewage treatment process. Meanwhile, compared the difference between the laboratory developed compounded enzyme and the foreign composite enzyme. The research results indicated that using biofilm process, the composite enzyme-biofilm process and the compounded enzyme-biofilm process for treating sewage, the removal rate of CODcr was separately 70.5%, 78.4% and 74.0% and that of ammonia nitrogen was separately 38.2%, 48.6% and 45.9%, which accounted for that under the strengthening action of biological accelerator, the treatment effect was remarkable for using biofilm process disposing channel disordered discharge sewage. Furthermore, the promoting effect of the compounded enzyme was equivalent to that of the composite enzyme for biofilm process, and the compounded enzyme could come into use instead of the composite enzyme.
