                  冶金废水处理方法

                  2019-03-13 15:40:06
                         冶金废水的主要特点是水量大、种类多、水质复杂多变。按废水来源和特点分类,主要有冷却水、酸洗废水、洗涤废水(除尘、煤气或烟气)、冲渣废水、炼焦废水以及由生产中凝结、分离或溢出的废水等。
                         冶金废水治理发展的趋向是:1.发展和采用不用水或少用水及无污染或少污染的新工艺、新技术,如用干法熄焦,炼焦煤预热,直接从焦炉煤气脱硫脱氰等;2.发展综合利用技术,如从废水废气中回收有用物质和热能,减少物料燃料流失;3.根据不同水质要求,综合平衡,串流使用,同时改进水质稳定措施,不断提高水的循环利用率;4.发展适合冶金废水特点的新的处理工艺和技术,如用磁法处理钢铁废水。具有效率高、占地少、操作管理方便等优点。三菱MBR膜一级代理商——深圳恒大兴业
