SBR法处理磺胺废水的试验研究

Research on treatment of sulfanilamide wastewater by means of SBR

采用 SBR法进行了磺胺废水的处理试验研究。结果表明 ,SBR处理工艺可有效地处理磺胺废水 ,在进水 CODCr浓度为2 90 1～ 3 14 7mg/L时 ,其去除率最高可达 94.5 % ,SO2 - 4浓度在 45 0 0 mg/L 以下对处理效率无影响 ;SBR反应停留时间以 3 2 h为宜 ,曝气周期以

The treatment of sulfanilamide waster water by means of SBR(Sequencing Batch Reactor) has been studied. Experimental results indicated that the sulfanilamide waster water could be treated effectively by SBR, the highest rate of removing of COD\-\{Cr\} was 94 5% with the incoming concentrations of 2901～3147 mg/L,and no effect on the under 4500 mg/L of SO\+\{2-\}\-4; It was also showed that the treating efficiency was better with the hydraulic retention time of 32 h and the react period of 8 h.\;
