Nghiên cứu xử lý nước thải sản xuất bằng phương pháp lọc kị khí kết hợp đĩa quay sinh học

Abstract

Nowdays, wastewater of rice vermicelli production polluted the water environment seriously. This research was tested by combination of the anearobic trickling filter with the rotating biological contactor to removal the impurities from the wastewater of rice vermicelli production. The performance of the anearobic trickling filter process at different flows was evaluated with the optimum flow being 1l/h in 24h time. The optimum time of the rotating biological contactor process was 32h. At the optimum condition, the observed COD, SS and NH4+ removal efficiency was in 97.4891.35 and 92.33%, respectively.
