| Abstract: | Chinese traditional medicine wastewater,which was affluent in glycosides,was treated by a process combined a simple hydrolyzation and acidification pretreatment with a aerobic submerged membrane bio-reactor(SMBR),which was designed specially,equipped with electro-control and backwashing device.The average chemical oxygen demand(COD) concentration in influent was 1090.1mg/L.The backwashing time was 5 minutes,and the average hydraulic retention time(HRT) was 5.97 hours.The average COD removal efficiency was 89.4%,and the COD concentration in effluent achieved the second level of the general wastewater effluent standard GB8978-1996 for the raw medicine material industry.It was a viable process for medium strength Chinese traditional medicine wastewater treatment. |
