| 中文摘要: |
| 研究复配混凝剂预处理促进剂CBS生产废水工艺。结果表明：在复配混凝剂用量为3.0 kg·t-1，混凝反应pH值为7.5，温度为55 ℃条件下预处理，促进剂CBS生产废水CODcr去除率达72%以上，多效蒸发蒸汽用量降低，蒸发效率提高，多效蒸发出的盐满足工业用盐要求，蒸馏中水经生化处理后水质满足回用要求，节约了清水用量。 |
| 英文摘要: |
| The pretreatment process of accelerator CBS production wastewater by composite coagulants was studied.The results showed that under the pretreatment conditions of composite coagulant dosage of 3.0 kg·t-1，coagulation reaction pH value of 7.5，and temperature of 55 ℃，the CODcr removal rate of accelerator CBS production wastewater was over 72%，the amount of multi effect evaporation steam was reduced，and the evaporation efficiency was improved，the salt produced by multi effect evaporation met the requirements for industrial salt use，and the water quality of reclaimed water after biochemical treatment met the requirements for reuse，saving the amount of clean water. |
