摘要
利用大孔弱碱性阴离子交换树脂浓缩电镀废液中的六价铬,使排放废水达到0.2 mg/L,低于国家0.5 mg/L的排放标准。同时将返洗交换的六价铬用甲醇还原制取磷酸铝铬胶粘剂,达到变废为宝的目的。
Cr（ Ⅵ ） from eleetroplating wastewater was concentrated by the big hole soft basic anon-exchange resins. It made the concentration of Cr（ Ⅵ ） decrease to 0.2 mg/L in the wastewater, which can meet the national standard. Meanwhile, the Cr （ Ⅵ ） of returning liquid was deoxidized by methyl alcohol, which was made into CrAl3（H2PO4）12 gum glues in order to change the wastes into something valuable.
