冷轧废水运行过程中的环境风险管理

冷轧废水是钢铁企业中较难处理的废水之一,具有成分复杂、污染物多、难以处理等特点,可以说是钢铁企业废水管理中的重点之重。以某钢厂3座冷轧废水处理站为例,详细介绍了冷轧废水的处理工艺,并结合废水站运行过程中发生的有关问题,对运行过程中的环境风险进行了分析,并提出或制定了有关措施,从而降低了环境污染风险。

Environmental risk management in cold rolling wastewater operation

Cold rolling wastewater is one of the intractable wastewater in iron and steel enterprises. It has many characteristics, such as complex composition, many pollutants and difficult to deal with.Three cold rolling wastewater treatment stations of a steel mill were taken as an example. The characteristics and treatment technology of the cold rolling wastewater were introduced indetail.Combined with the problems occurred in the operation of the wastewater treatment station, the environmental risk of the operation was analyzed,and the relevant measures were put forward or formulated to reduce the pollution of the environment risk.
