Abstract:

Synthesized heterocyclic organic sulfur bactericidal agent,and bis-quaternary ammonium salt are compo-sited with isothiazolone and disulfide acetonitrile solvent,in order to prepare a kind of biological slime treating agent TA-11,for water treatment. Its sterilizing effect and slime stripping effect are investigated. It has been applied to a large-scale chemical engineering enterprise. Research results show that the sterilizing rate of biological slime treatment agent is higher than that of commonly used sterilizing agent. When its dosage is 50 mg/L,the slime stripping ability is above 80%.

Key words: biological slime, sterilization, stripping, water treatment

摘要：

将合成的杂环有机硫杀菌剂及双季铵盐与异噻唑啉酮、二硫氰甲烷溶剂复配,制成一种水处理用生物黏泥处理剂TA-11,对其杀菌效果及黏泥剥离效果进行考察,并在某大型化工企业现场应用。研究结果表明,该水处理用生物黏泥处理剂的杀菌率较常用杀菌剂的杀菌率高,加药量为50mg/L时,黏泥剥离能力在80%以上。
