摘要
依据协同增效原理 ,在聚合氯化铝的制备过程中引入Fe(Ⅲ ) ,使Al(Ⅲ )和Fe(Ⅲ )发生共聚合 ,得到改进型复合碱式氯化铝。间歇溶气气浮试验结果表明 :影响改进型复合碱式氯化铝除油性能的主要因素是碱化度B ,其次是铁铝摩尔比和投量。现场试验结果表明 :与聚合氯化铝相比 。
Improved Basic Composite Aluminum Chloride (BCAC) can be obtained in preparation of poly aluminum chloride, if Fe(Ⅲ) is added for co polymerization of Al(Ⅲ) and Fe(Ⅲ). This is a more effect chemical on the synergism principle. Experiment of batch dissolved air floatation shows that the key factors which influences the oil removing capacity of BCAC are the alkalinity and the mol ratio of Fe/Al and the dosage of the chemical. Field run examination shows that improved BCAC is more effective than the poly aluminum chloride in oil bearing wastewater treatment as a de emulsification agent.
