摘　　要：针对造纸黑液的特点,提出应用水煤浆技术治理黑液的思路.该技术视黑液为资源,对黑液进行合理应用,从而达到了污水零排放目的.使用热天平对黑液水煤浆进行了热重分析.研究表明,黑液水煤浆具有着火点低、燃烬特性较好的燃烧特性.黑液水煤浆的工业炉燃烧试验表明,黑液水煤浆燃烧效率较高(为97 3 1% ) ,且燃烧后SO2 排放达标(SO2 排放浓度为67mg·m- 3) .The coal-water slurry(CWS) is introduced into treating the paper-making black liquid. The black liquid is regarded as a resource to achieve the no-emission. The thermogravimetric analysis on the black liquid coal-water slurry (BLCWS) shows that the characteristics are the lower kindling point and the better property of burnout. The combustion in the industrial boiler shows that the combustion efficiency(97.31%) is high, and the contaminant emission is within emission standard of air pollutants (emission concentration of SO_2 is 67mg·m^(-3)).
