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。
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 efficiency of COD was 71.12% using embedded immobilized method by R-1.Strain R-1 was identified as the best bacteria for the treatment of diary wastewater,with the treatment effect of embedded immobilized activated sludge method better than that of activated carbon absorbing activated sludge method and suspended bacteria method.
