摘要
随着我国经济的增长和工业生产的快速发展,焦化废水的处理问题备受人们关注。焦化废水是在煤的高温干馏及煤的净化过程中产生的,具有较高的毒性、性质不稳定、组成成分非常复杂,对环境有着极大的污染性,且非常难降解。焦化废水的排放对农业生产有着极大的影响,不利于我国农业的发展,如何解决焦化废水的问题迫在眉睫。本文主要介绍分析了生物法、化学法、物化法及循环利用法等处理焦化废水技术的优缺点及相关研究进展。
With the rapid development of China’s economy and industrial production, the treatment of coking wastewater has attracted much attention. Coking wastewater is produced in the process of high temperature distillation of coal and purification of coal. It has high toxicity, unstable nature, complex composition, great pollution to the environment and is very difficult to degrade. The discharge of coking wastewater has a great impact on agricultural production, which is not conducive to the development of agriculture in China.How to solve the problem of coking wastewater is imminent. In this paper, the advantages and disadvantages of biological, chemical,physicochemical and recycling methods for coking wastewater treatment and related research progress are introduced and analyzed.
