| Abstract:AF-SMBBR combined process was used to treat pulping effluent to investigate the CODCr and SS removal effect when this process was in the stages of biofilm colonization and stable running after the success of biofilm colonization, and to explore the effects of hydraulic retention time (HRT), and dissolved oxygen (DO) concentration on COD removal rate. The results of experiment showed that under the operation condition that influent temperature was 18～28℃, pH value was 6.5～8, CODCr concentration was 11000～15000 mg/L, SS concentration was 20600～26600 mg/L, hydraulic retention time (HRT) was 8 days, effluent CODCr maitained in less than 400 mg/L, the average removal rate was up to 97%, effluent SS was stable in less than 350 mg/L, the average removal rate was up to 98%. |
