Abstract

Sucrose wastewater is a kind of wastewater with high concentration of organic and color. In the paper, ABRBAF( anaerobic baffled reactor and biological aerated filter) process is adopted to treat this wastewater, in which the factors affecting the treatment are analyzed and the optimal operating parameters are also determined. The results show that, the optimal operating parameters should be: the HRT of ABR is 24 hours; the hydraulic loading of BAF is 1. 59 m3/( m2·h) and DO is 5. 8 mg/ L and under this conditions, the effluent of COD is than 100 mg / L.
