Application of HUSB-modified SBR process for treatment of dairy wastewater

doi:10.11894/iwt.2019-0071

Abstract

Abstract:

The HUSB-modified SBR process was applied to treat the dairy wastewater. The operation results showed that the process has advantages of stable operation, low running cost, resistance to shock loading and flexible operation. When the influent COD, SS and NH₃-N are 987, 226, 27.2 mg/L, respectively, the corresponding effluent COD, SS and NH₃-N are 56, 35, 9.3 mg/L, respectively. The effluent quality can fully meet the standard of class Ι specified in the Integrated Wastewater Discharge Standard(GB 8978-1996).

Key words: dairy wastewater, HUSB, hydrolytic acidification, SBR process
