摘　　要：丁辛醇装置缩合系统在反应过程中排出一部分含碱废水,其中COD大于40000 mg/L,经多效蒸发及汽提系统处理后的废水COD小于500 mg/L,可回收部分有机物,既有较好的经济效益,又减轻了下游污水处理压力。Part of alkaline wastewater is discharged in the condensation system of butyl octanol unit. The wastewater COD can be reduced to less than 500 mg,/L from more than 40 000 mg/L through multi - effect evaporation and stripping process. Meanwhile, part of organic phase earl be recovered, which is good to economic benefit and downstream wastewater treatment.
