摘要
本试验采用氢氧化物共沉、还原凝聚和活性炭吸附对Cu-EDTA废水进行了工艺条件的研究,获得了良好的效果。对于三种方法的工艺条件与除铜的关系,作了探讨。结果表明,在严格控制各自特定的条件下,经上述方法处理均可使出水残Cu浓度≤1mg/l。使用活性炭吸附法时,还可以达到铜回收和水回用的目的。
A study on the technological condition for treating Cu-EDTA wastewater by hydroxide coprecip- itation,reduction coagulation and activated carbon adsorption was made.By using the methods mentioned above,a satisfactory effect was achieved,and the correlation of technological conditions with removal of copper have been discussed.The result showed that Cu 1 mg/l in drainage could be abtained by these methods while the respective specified conditions were controlled strictly.Copper could be recovered and the treated water could be reused by the method of activated carbon adsor- ption.
