摘　　要：以硫酸盐竹浆生产系统的中段废水为对象,采用混凝-氧化-吸附的方法进行综合处理,对废水处理的效果进行了研究。实验结果表明:采用PAM-PAC混凝、Fenton氧化和粉煤灰吸附相结合的方法处理中段废水,在优化的条件下可使废水COD降至64 mg·L-1、SS降至19 mg·L-1、色度降至5倍、pH 6.50,达到了《制浆造纸工业水污染物排放标准》(GB 3544-2008)的排放要求。Using the middle stage wastewater of kraft bamboo pulping process as the research object, the synthetic method of coagulation-oxidation-absorption was used to treat the wastewater, and the treatment effects were studied. The results showed that after the wastewater was treated under the optimized condition, COD decreased to 64.24 mg·L^-1, SS decreased to 19 mg·L^-1 chroma decreased to 5; and pH was 6.50; all pollution indexes of water could meet the requirements of the state standard GB 3544- 2008 of China.
