Study on the Combination of Fixed Bed and Moving Bed Biofilm Reactor for Papermaking Terminal Wastewater Treatment
Abstract:
Papermaking wastewater mainly consists of black liquor, intermediate wastewater and white water. It suffers from its heavy amount, high level suspended solids and poor biodegradable property. In this paper, a combination of fixed bed and moving bed biofilm reactor was conducted to treat paper making wastewater in order to make full use of the advantages of both fixed bed and moving bed. As a result, the average values of COD, NH3-N and SS in effluent are 57.01 mg/L, 1.74 mg/L and 38 mg/L, respectively. The quality of the effluent could meet the demands of the Chinese standards for papermaking industrial water discharge pollutant.
