针对某化纤厂黑液处理站的运行现状及存在的问题，对采用酸析木素法处理棉浆黑液的应用条件进行了研究。结果表明：以酸析法替代化学絮凝法处理棉浆黑液，不仅CODcr，及色度去除效率明显提高，还可以大大节约废水处理成本，达到“以废治废”的目的；采用先生化处理后酸析、中和的工艺比先酸析、中和后生化处理的工艺效果更好，棉浆黑液的总CODcr，及色度去除率可分别达88％和95％左右。

The paper studied the applying conditions of acidification treatment of cotton pulp black-liquor according to the operating situations and existed problems. Experiment results showed ： comparing with flocculation, Acidification not only could improve the removal rates of CODer and chroma, but also could save the cost of wastewater treatment by utilizing the waste acid; the effects of biological ＋ acidification package process, which the removal rates of total CODer and chroma reached to 88% and 95% respectively, were ...
