Pilot-scale Study on Treatment of wastewater for natural rubber processing by Bioenhanced Technology

摘要

1-level anaerobic and 2-level aerobic bio-film treatment process is adopted in the test. Complex microbial inoculants are added to the system to make sure the system has abundant bio-phase and stable biomass. The paper has discussed the startup and stable operation conditions of the system and analyzed the degradation effect of microorganisms in each reaction tank within the wastewater treatment cycle. The result indicated the effect of treatment of wastewater generated from natural rubber processing is favorable and the effluent quality is stable. Besides, Discharge standard of wastewater pollution for natural rubber processing NY687-2003-Grade I can be reached. The removal of pollutants is mainly completed in 1-level anaerobic pool and 2-level aerobic pool.
