摘要
用工业苯做萃取剂,采用多塔对流萃取的方法回收废水中的乐果。其乐果回收率可达到90%,萃取后得到的萃合苯可直接配乐果乳剂而不影响产品质量。此工艺简单,操作方便有较显著的经济效益,也有一定的环境效益。
Taking industry benzene as extraction agent,rogor is reco- vered from rogor synthesis waste water by multipolar counterflow extra- ction.Its extraction field of rogor can reach above 89%.The obtaining benzene from this system can be directly perpared in the rogor solvent, and the product standard is not effected.This technology is very simple witn economic and environmental efficiency.
