破乳絮凝一体化体系的制备及性能评价.

In order to solve the pollution problem of oily wastewater to the environment. 3-butanol was used as initiator, ethyleneoxide CEO), propylene oxide (PO) and methacryloxyethyl trimethylammonium chloride (DMC) were used as main raw materials. The intermediate polyether demulsifier ( PEO-PPO-PEO) was successfully synthesized under high temperature and high pressure. The demulsifying flocculant (PEO-PPO-PEO-PDMC) was synthesized by block polymerization of the intermediate and DMC. The structure was characterized by FTIR, SEM, chemical titration and particle size analysis, and the oil-water separation test was carried out. The results showed that the molecular weight of polyether demulsifier is 2 922, which has demulsification function. The RSN of demulsifying flocculant is 12. 8, which has good hydrophilicity. With the increase of demulsifying flocculant concentration, cloud point decreased gradually. Finally, through the demulsification flocculation experiment, it is concluded that the demulsification flocculant can achieve good oil-water separation. [ABSTRACT FROM AUTHOR]
