非化学药剂阻垢技术分析与研究

Non- chemical agent anti- scale technology analysis and research

化学水处理药剂因具有使用效果好、见效快等优点,广泛应用于工业循环冷却水系统设备的阻垢、缓蚀、杀菌灭藻处理,但同时也具有使用成本高、冷却水系统实际运行浓缩倍率不高、在冷却水排污时因加入化学药剂增加了对环境影响的程度等缺点,在节水减排方面仍存在一定的不足。随着国外冷却水处理技术及产品的不断引进,非化学加药法处理循环冷却水也逐渐有成功应用的工程实例报道。本文对非化学药剂法处理循环冷却水的国内工程实例进行了大量的调查研究,对使用效果及影响因素进行了分析,对工程应用设计进行了讨论。

Chemical agent is widely used in industrial circulating cooling water treatment to prevent scale and corrode,disinfect and remove algae because of its good performance and quick effect. However,the agent treatment method has some shortcoming,such as high cost、low concentration ratio、more impact on environment of chemical agent in the discharged waste water. There is still some deficiency in respect of water-saving and emission reduction. With the abroad water treatment technology and equipment is introduced to home,success projects of non- chemical agent treatment for the circulating cooling water are reported little by little. In this paper,large amount of investigation and study of non- chemical agent treatment of circulating cooling water projects is done,usage effect and influence factors are analyzed,and engineering design is discussed.
