陶瓷工业固体废物资源化利用现状

陶瓷制品在生产过程会产生大量固体废物,其中大部分是开裂或变形陶瓷产品、在加工中产生的废料以及陶瓷残次品等。随着陶瓷产量的迅速增长,产生的固体废物日益增加。目前,我国陶瓷工业废物的处理与利用率比较低,致使大量废渣挤占耕地、污染环境,限制了陶瓷工业的发展。陶瓷工业固体废物的处理与利用己成为陶瓷工作者和环境工程技术人员共同关注的问题。主要介绍了陶瓷工业固体废物的来源及分类,目前国内外对于陶瓷工业固体废物资源化利用取得的研究成果。对陶瓷工业固体废物的有效利用,不仅缓和了陶瓷企业面临的环境保护压力,还将有效实现经济社会的可持续发展。

THE CURRENT SITUATION IN UTILIZATION OF SOLID WASTE RESOURCE OF CERAMIC INDUSTRY

The production process of ceramics bring large quantities of solid waste,most of which are cracking or deformation of ceramic products,waste produced in the polishing and defective electronic ceramic products,etc.With the rapid growth of ceramic production,solid waste is increasing quickly.At present,the treatment rate and utilization of ceramic waste is relatively low,resulting in a large number of arable land had been occupied and the environment polluting by the waste,which also limits the development of ceramic industry.It has become common concern of the ceramics industry workers and environmental researchers that treatment and utilization of solid waste of ceramic industry.The main source of ceramic waste and its varieties were analyzed,and the comprehensive utilization of ceramic waste at home and abroad was discussed.Effective use of ceramic waste,will not only solve the enormous environmental pressure of ceramic enterprises,also achieve sustainable development of economy and society.
