焦化废水深度处理及回用研究进展

Research Progresses on Treatment in Advanced and Reuse Technology of Coking Wastewater

焦化废水经生化处理后虽能达标排放,但仍对水体造成污染。若再经深度处理循环用于工业生产,则具有重大的经济效益和环境效益。通过从有机物的去除和盐分的去除两方面综述了焦化废水深度处理的方法、原理、进展以及优缺点。提出了今后发展的方向。

Although the coking wastewater treated by the second biochemical method can reach the standard of discharge, it may still cause water pollution. If it is treated further by the advanced treatment, the recycling of such effluent in industrial production may create economic and environment benefits. From two aspects of the removal of organic matter and salt removal, the methods, principles, applied prospects and the advantages and disadvantages of the advanced treatment of coking wastewater are expounded. In the end looking forward the direction of development in the future.
