Study on straw pulp gray water treatment by Anaerobic Baffled Reactor

This paper presents the research work of treating straw pulp gray water by ABR, The author examines the effects of COD removal rate at different hydraulic retention time,and different volume load by ABR, Results have shown: as the HRT is 8 h, COD removal rate is 40.5%, raises the biodegradability (BOD/COD)value from 0.25 to 0.52. Greatly improved the biodegradability of wastewater.
