摘　　要：皮革固体废弃物的再生利用涉及环境保护与资源利用问题。皮革固体废弃物中含有重金属铬,其循环利用受到限制。目前已报道的含铬固体废弃物再生利用的研究与成果在付诸于技术应用时存在明显问题。文章综述了含铬废固的处理方式,及其在静电植绒、橡塑填料、吸附剂、蛋白填料等方面的利用现状,以及各种利用中所面临的诸多问题,包括胶原蛋白的含铬量,废固的利用率,二次污染的出现等。The recycling of solid leather waste involves environmental protection and resource utilization issues.Leather solid waste contains heavy metal chromium,so its recycling is restricted.The reported researchresults on the recycling of chromium-containing solid waste have obvious problems when they are put into technical application.This paper reviews the treatment methods of chromium-containing waste and their utilization status in electrostatic flocking,rubber and plastic fillers,adsorbents and protein fillers,and some of the related issues that need to be addressed in the recycling,including the chromium content of extracted collagen,the utilization rate of solidwaste and the occurrence of secondary pollution.
