焦化废水处理技术及其应用研究进展

摘要

介绍了焦化废水的特点及危害,综述了国内外几种主要的焦化废水处理技术及其应用研究情况(如物理法、化学法、物化法和生化法等),重点介绍了生化法中的生物脱氮技术、高效微生物+O/A//O生物脱氮组合工艺等新技术的最新动态,并分析比较了其优缺点,指出了焦化废水处理技术存在的主要问题及今后的发展方向.%The characteristic and hazard of coking wastewater are introduced. The treatment techniques of some kinds of coking wastewater and the research on their application situation in China and abroad,including physical method, chemical method ,physical-chemical process and biochemical method ,are reviewed. The newest trends of combined processes, such as the biological denitrification in biological method, highly efficient microorganism+O/A/O biological denitrificaion etc., are introduced emphatically. The advantages and disadvantages of these approaches are analyzed and compared, and the existing inadequacies and future development directions are pointed out.
