摘要：

采用常压蒸馏—动态强化微电解—Fenton试剂—中和沉淀工艺处理高浓度增塑剂废水,试验结果表明:经该工艺处理后,原水COD_Cr由105600mg/L降为44521mg/L,去除率达到57.8%,B/C为0.53,为后续处理创造了良好的条件,该工艺具有可回收有机物、易于工程化等优点。微电解处理过程中产生的Fe²⁺可作为后续Fenton试剂法的铁源,降低了运行费用。

Abstract:

The distillation-dynamic-micro-electrolysis-Fenton-neutralization-sedimentation process has been used for treating plasticizer wastewater with high concentration. The results of the research show that, after the treatment,the COD_Cr of the original water decreases from 105 600 mg/L to 44 521 mg/L, the removal rate reaches 57.8% and the B/C is 0.53. The changes create good conditions for the following treatment. This method has many advantages, such as reclaiming some organisms and being easy to put into practice. The Fe2+ produced in the process of microelectrolysis treatment could be used as a source of iron for the sequent Fenton process, which decreases the operation cost.

Key words: plasticizer, wastewater treatment, dynamic-micro-electrolysis, Fenton
