relovery apparatus of waste acid

The mixture of ferrous sulfate,spent acid,from the metal residue in electroplating was used to prepare a coagulant agent for the treatment of dyeing wastewater with high content of color chrominance and COD.

为了处理高浓度、高色度、高COD的印染废水,利用硫酸亚铁、工业废酸和金属下脚料自行配制了复合混凝剂,并将其与聚合双酸铝铁、聚合氯化铝铁、硫酸亚铁对印染废水的混凝效果进行对比。
