中低温煤干馏废水处理的工程问题

The Issues Related to the Medium-low Temperature Coal Pyrolysis Wastewater Treatment

近年来随着煤焦油加氢行业的快速发展,煤焦油需求量快速增长,使得生产煤焦油的中低温煤干馏装置日益增多。中低温煤干馏废水属于焦化废水中较难处理废水类型,在国内尚无运行成功的工程,就中低温煤干馏废水处理工艺选择和工程设计上存在的难点及其解决的思路进行了分析,以供借鉴。

In recent years , the demand of coal tar expansion was accompanied by an increasing number of the coal tar hydrgenation projects , but there was no successful case for any medium -low temperature pyrolysis wastewater treatment, and the topic difficulties were introduced , key and solution in engineering design were analyzed to the reference.
