摘要
含铬制革废弃物经过适当处理可以回收其中的能量、重金属铬和胶原蛋白,但目前不合理的处置造成了环境污染及资源浪费。本文简述了含铬制革废弃物的来源和处置现状,综合国内外最新的含铬制革废弃物处理的文献,系统总结了含铬制革废弃物处理方式的相关研究,将处置方式分为直接处理和间接处理两大类分别进行阐述,详细介绍了吸附剂、热解、焚烧这3种直接处理方式及氧化法、酸水解法、碱水解法、酶水解法这4种间接处理方式,分析了每种处置方式的原理、存在的优缺点和应用前景,简述了各种处置方式的主要作用以及优缺点对比。最后提出了含铬制革废弃物处置的研究思路,特别是开展含铬制革废弃物热解和焚烧过程中燃烧和污染物排放机理研究。
The disposal of chromium containing tannery waste can recover the energy,chromium and collagen,but the unreasonable disposal has caused environment pollution and waste of resources. In this paper,the source and the current situation of disposal of chromium containing leather wastes were described. Based on the latest domestic and foreign chromium tanning waste processing literatures,the related researches of chrome tanning waste treatment and disposal were summarized. The disposal methods can be divided into two categories：direct treatment and indirect treatment. Three direct treatments including adsorbent,pyrolysis,incineration and four indirect treatments including oxidation,acid hydrolysis,alkaline hydrolysis,enzymatic hydrolysis were described in detail. The principle,advantages and disadvantages,and application prospect of each disposal method were analyzed. The main functions of various disposal methods were briefly described. Besides,the advantages and disadvantages of each method were compared. At last,the research ideas of chromium leather waste disposal were put forward. Especially,the mechanism of combustion and pollutant emission during the process of pyrolysis and incineration of chromium containing tannery wastes will be studied.
