摘要

用特种表面活性剂使热力学稳定的微乳液变成热力学不稳定的乳状液

并发现该种特种表面活性剂与聚合物复配后能使微乳液油水分离。通过透射电镜(TEM)分析发现含有不溶性有机物的透明脱墨造纸废水的分散颗粒远远小于可见光的波长

呈现微乳液状态

以该种透明废水作为实验对象

用特种表面活性剂与聚合物LYPW-301复配后分离该种微乳液状废水

通过化学需氧量(COD)测定表明:这种分离方法能够有效降低该种微乳液状废水的COD值。通过TEM分析微乳液和乳状液显微状态的变化探讨了微乳液的油水分离机理。这种分离方法能够有效地应用于其他各种造纸透明废水和油田透明废水的分离中。

Abstract

A special surfactant can make thermodynamically stable microemulsion liquid change to thermodynamically unstable state

and its complex with a polymer can do the microemulsion separation into a mixture of oil and water.It is found by transmission electron microscopy(TEM)analysis that size of particles dispersed in transparent deinking paper wastewater containing insoluble organic matter is much smaller than visible light wave-length

and this wastewater is at microemulsion state.So

the transparent deinking paper wastewater was taken as test sample

and treated with this complex(a mixture of special surfactant cBPE-2030 and polymer LYPW-301).The chemical oxygen demand(COD)was determined. The results showed that COD value after treatment with this complex was significantly reduced.The mechanism of oil and water separation was explored by TEM analysis for microscopic state change of microemulsion and emulsion liquids.The method separating oil and water of microemulsion could be effectively applied to other transparent wastewater from papermaking and oilfield

whose separation

in general

is difficult.
