石油化工装置循环冷却用水约占生产总用水量的９０ ％ 。结合扬子巴斯夫苯乙烯合资工厂的工程实例，从浓缩倍数的计算与取值、循环冷却水处理药剂的选择和计算、菌藻处理方法的确定、旁流水处理的设计等几方面具体说明循环冷却水处理的设计。
Circulating cooling water for petrochemical plants accounts for about 90% of the total production. Combined with the engineering example of the joint venture plant of BASF in Yangzi, the paper described in detail the calculation and value of concentration factor, the choice and calculation of circulating cooling water treatment agent, the determination of bacteria and algae treatment and the design of bypass water treatment. Processing design.
