摘要
地下煤气化废水主要为井下燃空区洗涤水和地面煤气净化及产品回收过程产生的废水,成分复杂,是国内外废水处理领域的一大难题。文章从生化法、物化法和化学氧化法3个方面综述了近年来国内外类似废水处理技术的研究进展,分析了现有处理方法的优缺点,并提出了地下煤气化废水处理技术的发展趋势。
Underground coal gasification wastewater is mainly produced by underground air burning area washing water and surface gas purification and product recovery process, and its composition is complex, which is a difficult problem in the field of wastewater treatment at home and abroad. In this paper, the research progress of similar wastewater treatment technologies at home and abroad in recent years is reviewed from the aspects of biochemical method, physicochemical method and chemical oxidation method, and the advantages and disadvantages of the existing treatment methods are analyzed. The development trend of underground coal gasification wastewater treatment technology is put forward.
