铝型材加工厂含铬废水治理

Chrome Wastewater Treatment of Aluminum Profile Processing Plant

铝型材加工厂喷涂车间排出的废水中,由于含有国家《污水综合排放标准》(GB8978-1996)中从严控制的一类污染物质——重金属离子铬,对水体造成的污染极大,必须单独处理。本文结合实际废水处理工程,提出了流程简洁的处理工艺,并就其工艺要点进行了总结。

The westawater drained from the spray coating shop of aluminum profile processing plat contains the heavy metal Cr ion, according to the'Integrated Wastewater Discharge Standard'(GB8978-1996),which is the first class pollutant and must be strictly controlled.The chrome wastewater does great harm to the water body,so it must be treated separately.Taking aim at a chrome wastewater treatment project,the paper puts forward a treating process with short,and simple process flow,and summarizes its main points.
