The waste water contained 2~3 g/L copper using 201×7OH-strong-base anion exchange resin and 732Na strong-acid cation exchange resin are performed respectively.Results of investigations reveal that the cation exchange reaction occurs easily at the higher temperature,but the anion exchange reaction is restricted at the same condition.The high efficiency of treating waste water can be achieved with the method of multi-stage exchange using anion and cation exchange resin.
