生物质炭含有丰富的营养元素,具有孔隙发达、吸附性强、比表面积大等特点,为解决近年来城市污泥堆肥处理研究中的热点问题,介绍了生物质炭的基本特性,综述了生物质炭在城市污泥好氧堆肥过程中对堆体基本性质、堆肥效果及产品安全等方面的研究进展,生物质炭能提高城市污泥堆肥效率,降低其堆肥产品中重金属的生物有效性,但在大规模应用前还需要做进一步深入细致的研究。
Biomass charcoal have rich nutrients,with developed pore,strong adsorption and large specific surface area characteristics,in order to solve the hot spot in the study of urban sludge compost treatment in recent years,the basic characteristics of biomass carbon were introduced,biomass carbon was summarized in the process of city sludge aerobic composting of basic properties of the pile body,compost effect and the safety of products,the research progress of biomass carbon could improve the efficiency of urban sludge compost,reduce the biological effectiveness of heavy metals in the composting products,but it also need to detailed research before large scale further.
