Abstract:

The wastewater quality and situation in the wastewater treatment station of an grain & oil enterprise are described. The debugging process of the wastewater treatment system is introduced. Tracking monitor results show that the wastewater treatment system runs stably and the effluent quality is excellent. The effluent can meet the Second Grade Standard of the Integrated Wastewater Discharge Standard （GB 8978—1996). It is a feasible technology for the treatment of wastewater from grain & oil enterprises.

Key words: wastewater from grain &, oil enterprises, highly efficient gas flotation, hydrolytic acidification, biological contact oxidation
