Abstract
Pilot test is made to research the treatment effect of traditional Chinese herbal drug synthetic wastewater by hydrolysis acidification and two-stage biological aerated filter (BAF) on the base of analyzing the reasons that the effluent of existing process failing to reach the standard. The experimental result shows that when the influent COD, SS and colour average 970 mg/L, 145 mg/L and 130 times respectively; those in effluent are 80 mg/L, 43 mg/L and 130 times. The effluent quality conforms to the first class criteria specified in the comprehensive wastewater emission standard.
