紫胶深加工废水处理工艺研究

摘要:

对初沉+Fenton+絮凝沉淀+水解酸化+SBR的组合工艺处理紫胶树脂深加工废水影响因素进行了考察,对运行参数进行优化.H2O2投加量1 000mg/L,PAC投加量300mg/L,阴离子PAM投加量6mg/L,水解酸化停留时间48h,好氧停留时间6d时,出水COD 112mg/L,去除率为96%.废水中含有一些不能被水解酸化菌和羟基自由基氧化的物质,更高效有针对性的氧化技术有待研究.

The influence factors of the lac resin processing wastewater treatment by combined process of primary sedimentation ＋flocculation＋ biochemical reactions＋ Fenton＋ SBR were investigated in this paper,and the operating parameters were optimized.Under the conditions of the dosage of PAC 300mg/L,anionic PAM 6mg/L,hydrolytic acidification residence time 40 h,aerobic residence time 6d,the dosage of H2O21000mg/L,the effluent COD 112mg/L,the removal rate is96%.The wastewater contains substance that can not be oxidized by hydrolytic acidification bacteria and hydroxyl radicals,more efficient and targeted oxidation technology is to be studied.
