摘　　要：兰炭废水中污染物浓度高、成分复杂、可生化性差、处理难度大,研发经济高效的兰炭废水处理技术具有重要意义。综述了兰炭废水处理技术的研究进展,评述了各种方法的特点:资源回收预处理技术,可回收兰炭废水中有价值的物质,降低污染物浓度,提高废水的可生化性;高级氧化技术作为预处理技术,可将大分子污染物降解为小分子污染物;深度处理技术,可进一步降低污染物的浓度或直接去除,使出水达标排放。最后提出了兰炭废水处理技术的研究和发展方向。Semicoke wastewater is hard to treat due to high content of pollutants, complicated components and poor biodegradability. So it is of great significance to study economical and effective semicoke wastewater treatment technologies. The paper has summarized current progress of semicoke wastewater treatment technology and reviewed characteristics of different methods. The resource recovery pretreatment technology can recover valuable substances in the wastewater, reduce the pollutant concentration, and improve the biodegradability of wastewater. Taking advanced oxidation technology as the pretreatment technology can degrade the large molecular pollutants into small molecular pollutants. Also, advanced treatment technology can further reduce the pollutant concentration or directly remove the pollutant so as to make discharge of water meet the standard.Finally, this paper mainly presents the research and development direction of semicoke wastewater treatment technologies.
