焦化废水预处理技术的应用与展望

The Application of and the Prospect for the Pre-processing Techniques for the Coking Wastewater

焦化废水是煤制焦炭,煤气净化及焦化产品回收过程中产生的废水,其成分复杂多变,因此应尽可能在生化处理前降低其浓度或改变其分子结构,提高废水的可生化性。介绍了焦化废水预处理过程中所用的技术和方法,并对焦化废水预处理技术的应用前景进行了展望。

The coking waste water, which is produced in the courses of the production of the coke from the coal, the purification of the gas, and the recovery of the coking products, possesses complicated and variable components, therefore, should reduce its concentration or change its molecular structure as much as possible before the biochemical process to increase the biochemical possibility of the waste water. This paper introduces the techniques and methods used in the preprocessing of the coking wastewater, and looks forward to the application prospect of the preprocessing techniques fir the coking wastewater.
