摘要
对高锌离子,高COD浓度的7-ACA废水,提出了一套较完整的去除锌离子,降低COD浓度的工艺方法;并对锌进行回收,重新制成醋酸锌晶体。
This passage put forward a full set of technology method that can remove zinc ion and reduce COD density for 7-ACA wastewater with high zinc ion and high COD . This method also can callback zinc and make it to crystal of zinc acetate.
