摘要：
针对焦化废水生化处理出水中存在COD、色度和浊度偏高等问题,在综合分析各种焦化废水深度处理方法的基础上,提出Fenton试剂氧化、混凝及联用技术的方法,对生化后废水进行深度处理,确定了合适的Fenton试剂氧化混凝工艺条件。研究结果表明,经联合工艺处理后的焦化废水达到了国家一级排放标准,COD去除率达到88%,色度、浊度去除率达到90%以上,该联合工艺具有良好的应用前景。

Abstract:
The study mainly aims at the treatment of coking wastewater in which the COD,chroma and turbidity are higher than the national discharge standard. On the foundation of investigation the methods of advanced treatment of coking wastewater after biochemical treatment,suitable Fenton reagent oxidation and coagulation technical conditions are made sure. The result shows that this technology can efficiently remove pollutants and the total removal rate of COD can reach 88%,and the removal rate of the chroma and turbidity can both reach over 90%, the outflow of coking wastewater can meet the national discharge standard. Its foreground is good.
