焦化废水的生物处理方法的研究进展

摘要

Coking wastewater usually comes from primary cooling of coke oven gas, steam condensate in the coking production. In this article, the current status and progress of the biological treatment of coking wastewater was introduced. The research status and characteristics of these methods were analyzed and compared, such as activated sludge process, contact oxidation process, biological filter process, biological fluidized bed process, biological anaerobic treatment of wastewater, bioactivity carbon method and so on. In addition, some suggestions about the future research were proposed.%　　焦化废水主要来自焦炉煤气初冷和蒸汽冷凝废水，以及焦化生产过程中的生产用水。主要介绍了国内外焦化废水的生物处理方法研究现状及进展，主要包括活性污泥法、接触氧化法、生物滤池法、生物流化床法、废水厌氧生物处理法和生物活性碳法等，对这些方法做了比较，并对今后研究方法提出建议。
