| 摘要:采用厌氧生物滤池(AF)-特异性移动床生物膜反应器(SMBBR)组合工艺处理制浆废水,考察该工艺挂膜阶段以及挂膜成功后稳定运行阶段对废水CODCr和SS的去除效果,并探究了稳定运行期水力停留时间(HRT)、溶解氧(DO)浓度两个因素对CODCr去除率的影响。试验结果表明,在水温18～28℃、进水pH值6.5～8.0、CODCr浓度11000～15000 mg/L、SS浓度20600～26600 mg/L、水力停留时间8 d的操作条件下,出水CODCr稳定在400 mg/L以下,平均去除率高达97%；出水SS稳定在350 mg/L以下,平均去除率高达98%。出水水质达到GB8978—1996《废水综合排放标准》国家三级排放标准,可排入城镇废水处理厂进行深度处理。 |
| 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%. |
