The municipal sludge has the characteristics of complex components, high yield, high water content, high pollution and the like. In the processes of sludge storage, transportation and treatment, leachate is very easy to generate to pollute the underground water, and harmful gas volatilized at any time can pollute the surrounding atmosphere. The treatment modes of single anaerobic treatment, drying treatment, incineration, landfill, composting and the like are the most adopted treatment modes at present, and the defects of incomplete treatment, secondary pollution transfer, high cost and the like are the concentrated existence of various methods.
Currently, 3 types of sludge resource utilization modes are mainly used for land utilization, building material utilization and biomass fuel preparation, wherein the biomass fuel preparation is a mode of mixing sludge with industrial and agricultural wastes or clean fuel to prepare fuel with higher heat value for boiler combustion, and is a main mode of sludge resource utilization. The sludge prepared molding fuel mainly utilizes the characteristic that the sludge has lower heat value and can not be directly combusted, and the sludge is mixed with combustible to prepare the biomass fuel which is used as energy, so that the heat value of the sludge is fully utilized, the cost of sludge treatment is effectively reduced, and the sludge prepared molding fuel is an effective way for harmlessness and recycling of the sludge.
