摘　　要：用高铁酸钠对帘子布浸胶废液进行氧化混凝预处理,研究了高铁酸钠投加量、溶液pH值、助凝剂PAM投加量对废水处理效果的影响。结果表明,最佳处理条件为:高铁酸钠投加量5 mL/L,pH=7,质量分数0.1%的PAM投加量1mL/L,处理后水样COD_(Cr)80 mg/L,NH_(3)-N 55.07 mg/L,色度1倍,去除率分别为COD_(Cr)99.6%、NH_(3)-N 90.60%、色度99.97%。The self-made sodium ferrate was used for the oxidative coagulation pretreatment of the waste liquor from cord fabric dipping.The results showed that the optimal treatment conditions were as follows:sodium ferrate dosage 5 mL/L,pH=7,PAM dosage 1 mL/L with mass fraction of 0.1%.After treatment,COD_(Cr)was 80 mg/L,NH_(3)-N was 55.07 mg/L,and chroma was 1 times.The removal rate of COD_(Cr),NH_(3)-N and chroma were 99.6%,90.60%and 99.97%.
