Description

一种陶瓷品废料再利用工艺
技术领域
本发明陶瓷技术领域，尤其涉及一种陶瓷品废料再利用工艺。
背景技术
随着社会经济和陶瓷行业的快速发展，陶瓷工业废料日益增加。
它不仅对城市环境造成巨大的压力，而且还影响到城市经济的发展及陶瓷工业的可持续发展。
因此大量的废旧陶瓷如何处理能减少对环境及经济的影响已经成为人们关注的热点问题。大多数企业的陶瓷废料都通过填埋的方式来解决，但是填埋也需要占用大量土地。废旧陶瓷的堆积占用土地影响植被生长，从而影响当地空气中各粉尘含量；而废旧陶瓷的填埋不仅耗费人力物力，并且污染地下水质。对当地环境造成巨大压力，并且制约城市经济以及陶瓷行业的可持续发展，所以合理的处理和陶瓷工业废弃物资源回收利用是非常重要的。
