摘要
Abstract
According to the characteristics of oily sludge in the Daqing oilfield,the hot washing method was used for its processing. In order to enhance oil removal,an organic cationic flocculant was added for conditioning. The organic cationic flocculant was synthesized by aqueous solution polymerization of epichlorohydrin and triethanolamine with triethylenetetramine as modifying agent, and the influence of molar ratio of epichlorohydrin to triethanolamine,amount of triethylenetetramine, polymerization temperature,and reaction time on oil removal for oil sludge was investigated. The optimum synthesis conditions of the flocculant were determined,and the best conditions of hot washing in the treatment of oily sludge were also determined. The flocculant dosage was 160mg/L,pH was 7,when it was added simultaneously with field demulsifier,oily sludge removal rate was up to 82.34%,higher than the combined use of other flocculants and demulsifier. SEM analysis showed that after adding the flocculant,sludge flocs arranged closely,which was favorable for sludge flocculation.关键词
