摘要：

描述了用黄铁矿和还原铁粉为原料制备重金属废水净化剂的方法，以及该净化剂处理重金属废水的应用方法。该净化剂对重金属废水的处理效率受制备和应用两方面的多种因素影响。并对含砷、铜和镉的废水进行了处理，对温度、粒度、配比、pH值、用量、时间等影响因素进行了讨论。结果表明该净化剂的制备和应用是简单、有效和经济的。

Abstract:

It was descr ibed to prepare and apply an agent for heavy metals containing wastewater treatment with pyrite and reduced iron powder in this paper. The capacity of the agent was influenced by a few facto rs in two aspects of its pr epar at ion and applicat ion. The wastew ater containing arsenic, copper or cadm-ium was treated respectively. The temperature, gr ain size, ratio, dosage, pH and time were discussed. The results showed that the production and application of the agent are simple, effective and economical.
