污泥水热处理制备清洁燃料的研究进展
Research on clean solid fuel derived from sludge employing hydrothermal treatment
摘要
Abstract
Recently,the increasing amount of sludge is a challenge for industrial and municipal activities. Minimizing the volume of sludge and recovering energy so far have been the focus of research. This paper introduced the characteristics of sludge and its disposal status,then comprehensively compared the industrial application of hydrothermal treatment at home and abroad. Additionally,the advantages of producing clean solid fuel via hydrothermal treatment were pointed out,including the improvement of dewaterability,the upgrading of fuel characteristics,the stabilization of heavy metals, the lower cost and the reduction of pollutions from NOx,acid gas and fly ash. Meanwhile,the influence of hydrothermal temperature and time on the reaction pathways and conversion mechanism of different components in sludge were also discussed in detail. Finally,the main research direction of hydrothermal treatment for sludge was put forward. Studying the synergistic effect of sludge and other high moisture waste during hydrothermal process or combustion is considered as an important way to produce great quality fuel.关键词
