Study on Sewage Disposal by Bio-Film Process Dosing with Enzyme

Abstract:

The paper studied enhanced treatment of sewage from discharging points of rivers by bio-film process dosing with enzyme and investigated the promotion effect of enzyme on treatment of sewage by bio-film process. The removal of phenol in sewage was also researched. The experiments results indicated that during the ebb tide, the remove rate of phenol was stable (33%) on the eighth day in the dosing pools and it was stable (31.6%) on the eighth day in the contrast pool. During the rising tide, the remove rate of phenol was stable (30%) on the eighth day in the dosing pools and it was stable (27.2%) on the eighth day in the contrast pool. It indicated that enzyme had good promotion effect on bio-film process during the sewage treatment process. Biological accelerator-bio-film process could effectively reduce the impact of sewage on river and it had a good application prospect as the auxiliary means for water restore.
