浮选—杀菌处理剂的合成及其应用

Synthesis and Application of a Kind of Watertreatment Agent with Floatation/Bactericide Function

研制了一种浮选-杀菌多功能水处理剂,探索了该药剂主剂的合成条件,并对该药剂的浮选和杀菌性能进行了评价。该药剂主剂是用醇、环氧氯丙烷及胺类为原料合成的聚醚型季铵盐。实验结果表明:该药剂同时具有浮选和杀菌功效.当药剂用量为1～5 mg/L时,其除油率和固体悬浮物去除率均可达95%以上;对腐生菌、硫酸盐还原菌和铁细菌有很强的杀菌能力。该药剂可在pH为4～10的宽范围内使用。

A kind of watertreatment agent with floatation/bactericide multi-function was synthesized. Its synthesizing conditions were discussed, and the performance of floatation and bactericide was evaluated. The main component of the agent is a polyether with ammonium group, which is made up of alcohol, epoxy chloropropane and triamine. The experiments showed that the agent simultaneously has both floatation and bactericide function. When its dosage is 1～5 mg/L, both its oil removal ratio and suspended sohd removal ratio are more than 95% ; and it has high efficient bactericide capability to kill SRB, FB, and TGB. It can be used in a wide pH range of 4～10.
