水处理中含铁废料综合利用的研究进展

On the Reuse of the Iron-containing Waste Residues in the Wastewater Treatment

回顾了20余年来我国在水处理中综合利用含铁废料的研究进展。分别评述了副产品硫酸亚铁制备絮凝剂PFS的各种方法，废铁屑运用于内电解法水处理和其他含铁泥渣、废酸在水处理中的研究和应用现状。指出含铁废料综合利用中有待于进一步研究的若干问题。

The development of researches on utilization of the discards containing Iron in the wastewater treatment in the past more than two decades in China was briefly reviewed. About manufacturing method of Polymeric Ferric Sulfate(PFS)by using by-product FeSO4: 7H2O as raw material,Galvanio Corrosion with Iron filings and reuse of Iron-containing waste residues in the wastewater treatment are discussed respectively. Further research in the future on the reuse of Iron-containing waste residues is suggested.
