Abstract: It is a promising technology to treat sewage sludge,straw,algae and other waste biomass by using them to prepare coal water slurry(CWS),which achieves their reduction,harmless and resource utilization. There are varieties of biomass with complex structures,and thus it is of great significance to study the co-slurry ability of biomass and coal. The paper reviewed the type of wastes used to prepare biomass coal water slurry(BCWS),the modification methods of biomass,the various techniques used to study the characteristics of CWS,and the effects of biomass on the slurry ability of CWS. The high moisture content,developed pore structure,and complex composition of biomass like sewage sludge resulted in its poor slurry ability,but the pseudo-plastic behavior,thixotropy and stability of BCWS were better than that of CWS. The future researches of slurry ability of BCWS are to strengthen the research on the modification methods of biomass;to explore the microcosmic mechanisms on the co-slurry ability of biomass and coal;and to develop proper additives for BCWS.

摘要： 将污泥、秸秆、藻类等废弃生物质用于制备水煤浆，实现废弃物的减量化、无害化、资源化，是废弃物处置的发展方向之一。生物质种类繁多、结构复杂，开展生物质与煤共成浆特性的研究意义重大。本文总结了用于制备生物质水煤浆的废弃物种类、制备水煤浆前生物质的改性技术、研究生物质水煤浆特性所采用的测试技术以及生物质对水煤浆成浆性能的影响。污泥等生物质高含水率、孔隙发达、成分复杂的特点导致其不易于成浆，但生物质水煤浆的假塑性、触变性和稳定性比普通水煤浆好。最后提出了对生物质水煤浆成浆特性重点研究方向的思考：加强生物质改性预处理的研究；深化生物质与煤共成浆微观机理的研究；研究开发适用于生物质水煤浆的添加剂。
