制革工业含铬革屑资源化利用途径

在皮革生产过程中,将会产生大量固体废弃物,在自然条件下,固体废弃物中的有害物质将会通过水、大气、土壤等途径进入环境,给人类造成危害。含铬革屑作为制革固体废弃物之一,由于含大量铬,如果处理不当,将会对环境造成极大的危害。含铬革屑中的主要成分是胶原蛋白,经过适当处理可进行回收利用,创造经济效益。在环境问题日趋严重及资源日益紧缺的今天,含铬革屑的资源化利用将会具有重大的意义和广阔的发展空间。因此,本文就含铬革屑的资源化利用问题进行了简单综述。

Recycle Route of Chrome-contained Shavings Produced by Leather Manufacturing

There are large numbers of solid wastes generated during the producing process of learther. Under the nature condition, harmful substance in the solid waste will enter into the environment through water, air and soil. Chrome-contained shavings, as one of the solid wastes, will greatly endanger the nature if the chromium is not disposed appropriately. However, the collagen contained in chrome shavings can be recycled and then create economic benefits. Nowadays the problem of environmental pollution and the lack of sources are more and more serious, the chrome-contained shavings recylcing must be significantly. In this paper, the recycling of chrome-contained shavings was mainly reviewed.
