| 摘 要： | 文章采用SBR工艺比较了4株细菌R-1,R-2,R-3和R-4处理乳品废水的效果。结果表明进水COD为395.55mg/L的乳品废水,水力停留时间(HRT)为24h,细菌直接处理乳品废水效果最佳菌株为R-1,废水COD去除率为44.3%;通过活性炭吸附后处理效果最佳菌株为R-1,废水COD去除率为69.06%;通过海藻酸钠包埋后4株细菌处理效果最佳菌株为R-1,废水COD去除率为71.12%。通过4株细菌处理乳品废水效果的比较,得出处理效果最佳的菌株为R-1,海藻酸钠包埋后的处理效果好于活性炭吸附,直接处理的效果最差。

| Abstract: | Treatment effects of dairy wastewater were compared by 4 bacteria with suspended bacteria method,activated carbon absorbing bacteria method and embedded immobilized bacteria method using SBR process.Results showed that under the influent COD 395.55mg/L of dairy wastewater and hydraulic retention time for 24h,the best removal efficiency of COD was 44.3% using suspending bacteria method by R-1,the best removal efficiency of COD was 69.06% using activated carbon adsorption method by R-1,and the best removal ef... |
