| 摘 要： | 铬鞣法仍是皮革鞣制的最主要方法,由于一般传统的铬鞣铬的结合量只有60%～70%,这些三价铬直接排放不仅会造成环境污染,还会造成巨大的资源浪费。本文就现阶段国内铬鞣废液的处理方法和技术进行了综合评述,目前最实用有效的处理方法是用物化和生物处理技术,加之清洁化生产过程,使铬鞣废液回收高达99%以上,使得废液排放达到国家标准。

| Abstract: | Although at present a lot of methods for tanning,chrome tannage is still the main method of leather tanning.Beacause of the chromium combining amount of the conventional chrome tanned only 60 percent to 70 percent,These Cr3+ directly emissions will not only cause environmental pollution,also can make huge waste of resources.The usual treatment methods for chrome tanning wastewaterwere summarized in this study.At present the most practical and effective method is to use to materialize and biological treatmen... |
