| Summary: | 碩士 === 中原大學 === 化學工程研究所 === 84 === The pollution treatment of oil containing waste water,
especially on the oil in water or water in oil emulsion is
important on today's environment. And in the process of
treatment, generally , there is with organic polymer as a
untiemulsiierf in the chemical method, such as polyacrylamide
and quaternary ammonium cationic starch that can destroy the
surfactant around the oil in water emulsion and make the oil
layer rise to the surface of water. The guaternary ammonium
cationic starch,produced from cheap natural polymer of starch
and acid modified starch as raw material, a pollution free
quaternary ammonium cation starch has prepared. On the model
of artifical oil in water emulsion , quaternary ammonium
cationic starch was added to study the influence of the degree
of substitution, treating dosage, and mixing speed of agitation
on the percent light transmiss. It is found that the cation
starch under the same treating dosage , increasing degree of
substitution will increase percent light transmission. And
under the same percent light tranmission , increasing degree of
substitution , generally , will decrease treating dosage.
There is also found that under the same degree of substitution
and treating dosage , increasing fluidity will decrease percent
light transmission , and under the same fluidity and degree of
substitution, increasing treating dosage will increase percent
light transmission , but when exceed the proper treating dosage
the percent light transmission will decrease.
