循环冷却水处理新化学药剂的发展

随着水资源的日益紧张和排放标准的日益严格,要求循环冷却水处理药剂能适应高硬度、高碱度、高氯离子、高有机污染的需要,本文介绍的国外的新型药剂－－聚氨基聚醚基甲叉膦酸、膦酰基羧酸、聚天冬氨酸、过氧乙酸、４,５－二氯－２－正丁基－４－异噻啉丁酮等具有优良的阻垢和杀菌作用,并且对环境友好。

Development of New Chemicals for the Treatment of Circulating Cooling Water

As water resources are becoming increasingly short and standards for water discharge are getting more and more stringent,chemicals for the treatment of circulating cooling water are required to be adaptable to high hardness,high alkalinity, high chlorion and high organic pollutants.The new_type chemicals produced outside China introduced in this paper,such as polyamino polyether methylene phosphonae,phosphonocarboxylic acid, polyaspartic acid, peracetic acid,4,5_dichloro_2_noctyl_4_isothiazolin_3_one,etc., have excellent scale inhibiting and sterilizing effects and are friendly to environment.
