摘要
结合贵溪冶炼厂现行的废酸、废水处理工艺及设备，探讨废酸、废水中镉的处理问题。建议采用以下三种方法：废水采用泥浆循环，消石灰中和，提高ｐＨ值的处理法；废酸采用先石膏，后硫化，再泥浆循环的中和处理法；聚合硫酸铁法。
According to the existing treatment appratus of Guixi Smelter, three disposal processes for waste acid and water containing Cd are proposed:a.neutralization of waste water by white lime at increased pH with mud recirculation; b.neutralization of waste acid by gypsum and then sulphurization with mud recirculation; c.polymeric ferrous sulphate process.
