摘　　要：采用铁屑处理人造首饰废水。经处理后的废水，各项指标均达到国家排放标准。研究了铁屑用量、作用时间等的最佳值。与硫酸亚铁法做了比较，其优点是用量少、成本低、处理效果好，并做到以废治废。Waste water from imitation ornaments processing is treated with iron filings. After treatment, the contents of heavy metals, COD and suspension are lower than the national discharge standards. The amount of iron filings and reaction time are discussed. Compared with the ferrous sulphate method, the advantages of this method are: the amount of iron filings needed is small; its cost is low; its treatment effect is good; and it utilizes debris for waste water treatment.
