摘要
针对PTA精制过程废水中污染物成分复杂、化学需氧量(COD)高、难处理的特点,总结了国内外用于PTA废水处理的物化技术、生化技术及物化-生化联合处理技术,评析了各种技术存在的优缺点,并对PTA废水处理技术的发展趋势进行了展望。
For the complex composition of pollutants in wastewater,chemical oxygen demand(COD) high and refractory characteristics in the PTA refining process,some technologies commonly used on PTA wastewater treatment was summarized in the paper,such as physical and chemical technology,biochemical technology and physical and chemical-biological union processing.Meanwhile,the advantages and disadvantages of each technology were analyzed and the trends of PTA wastewater treatment technology were analyzed.
