浅谈循环冷却水系统的化学法水质稳定处理

Chemical Way of Water Quality Stabilization for Circulating Cooling Water System

缓蚀、阻垢、杀菌、灭藻是维持工业及建筑空调循环冷却水系统水质稳定的重要措施。重点介绍了化学法碱性复合配方阻垢剂、分散剂、缓蚀剂及杀菌灭藻剂的药剂种类、投加量计算、投加方式、投加点和注意事项。并简单介绍了旁滤处理及系统清洗预膜的重要性和操作方法。

Corrosion inhibition, scale retardation, sterilization and algae control play very important roles for water quality stabilization in circulating cooling water system of air condition facilities in industry and buildings. In this paper chemical formulations of composite basic agents, including scale retarder, dispersant, corrosion inhibitor and germ/algaecide are presented and dosage calculation, dosing method and location and other attentions deal with the application of these chemicals are given. Furthermore the importance and operation of external filtration and pre membrane growth for systematic clearing are presented briefly.
