摘要
合成氨生产中需要利用循环水对系统进行冷却降温,故而产生了循环冷却水排水。循环冷却水虽然属于清净下水,但经长时间多次循环冷却使用后,各污染物指标均容易超标。目前许多企业将其直接排放既污染了环境又造成了水资源的浪费。本文以北方某化工企业合成氨系统循环冷却水处理为例对循环水的处理进行研究。
In the production of synthetic ammonia, the circulating cooling water is used to cool the system, so the circulating cooling water is produced. Although the circulating cooling water belongs to the clean sewage, it is easy to exceed the standard of pollutants after long time and many times of circulating cooling. At present, many enterprises not only pollute the environment but also waste water resources. In this paper, the treatment of circulating cooling water in the ammonia system of a chemical enterprise in north China was studied.
