摘　　要：橡胶助剂废水属于难处理的工业废水,尤其是CBS(N-环己基-2-苯并噻唑次磺酰胺,英文名N-cyclohexyl-2-benzoth-iazole sulfonamide,简称Accelerator CBS)生产废水的COD达40000mg/L,并且含有杂环类有害化合物,难降解,难生化。经过絮凝沉淀、化学氧化、电化学法、吸附法等实验方法,处理效果都不是十分理想。采用热泵蒸馏技术对橡胶促进剂CBS的废水进行预处理实验,可使CBS废水的COD从40000mg/L降至1600mg/L,结果表明,该技术设备简单,投资少,操作方便,运行成本低,并能达到较理想的预处理效果。Wastewater from rubber promoter industry is a refractory wastewater containing CBS (cyclohexyl-2-benzoth-iazole sulfonamide) with COD up to 4 ×10~4 mg/L, and also containing hazardous heterocyclic compounds which are hard to degrade. After treating with floc-culation precipitation, chemical oxidation process, electro-chemical method and adsorption, still could not achieve satisfactory result. Using heat pump distillation technique for pre-treating rubber promoter CBS wastewater, the result indicated that COD could decrease from 4000mg/L to 1600mg/L, and the technical equipment was simple, less investment, easy to operate, lower cost and favourable efficiency.
