Abstract
The wastewater of a reconstituted tobacco company in Guangdong Province has the characteristics of high concentration and complex composition. By comparison, the pretreatment (Grid / Air Flotation) and Up-flow Anaerobic Sludge Bed / anoxic / aerobic process combined with advanced treatment process (Air Flotation / Ozonation-Biological aerated filter) were applied. After stable operation of the system was achieved, the effluent quality could meet the first level standard of the maximum allowable discharge concentration of the second class pollutants in the second period of the Discharge limits of water pollutants (DB44 / 26-2001) in Guangdong Province. This paper introduces the process flow of the project and the design parameters of the main structure, and provides a reliable reference for the similar engineering design.
