摘要: 随着“绿色发展”观念的持续推进,传统制革行业因其生产工艺中产生的污染而逐渐受到冲击。制革鞣制过程所产生铬鞣废水及其处理后所产生的污泥,若得不到有效处理和利用,不仅会对环境和人的身体健康产生危害,还会造成铬资源的大量浪费,经济、高效的铬处理与利用技术的开发已迫在眉睫。基于此,分别对制革过程产生的含铬废水及其沉淀过程产生的污泥中铬的处理方法进行了介绍,如循环利用法、电絮凝法、生物沥滤法和超临界水氧化法等,并对含铬废水和污泥中铬的处理回收方法的发展进行了总结和展望,旨在为我国皮革行业的绿色化发展提供一种新的思路。

Abstract: As the concept of "green development" continues to be promoted, traditional tanning industry is increasingly affected by the pollution generated during its production process. The chromium tanning wastewater and sludge produced by the tanning process pose significant environmental and health hazards if not effectively treated and utilized. Additionally, improper handling leads to substantial waste of chromium resources. The development of economical and efficient chromium treatment and utilization technologies is urgent. This paper introduces various treatment methods for chromium-containing wastewater and sludge produced during the tanning process. These methods include recycling, electrocoagulation, bioleaching, and supercritical water oxidation. Furthermore, it provides a summary and outlook on the development of recycling methods for treating chromium in wastewater and sludge. The aim is to foster a new way of thinking about the development of China's leather industry towards greener practices.

Key words: leather industry, chromium tanning wastewater, chromium containing sludge, recycling method, acid leaching
