Problems solved by technology

However, the cost of disposal is high, and the problem of secondary environmental pollution during disposal is serious
Moreover, since the above-mentioned solid wastes collected are mostly lumpy or clustered semi-solid, the way of direct blending and burning is not suitable for transportation or extensive transportation, resulting in large fluctuations in gasification and cracking temperature, and even accidents such as blockage of the furnace body occur frequently, which affects the safety of the furnace body Great impact on lifespan

Abstract

The invention relates to a method for treating distillation residue kind waste and a product obtained through the method. The method is characterized in that porous mineral waste rich in micron-scaleor nano-scale active calcium oxide, aluminum oxide, iron oxide, silicon oxide and like such as smoke fly ash of a power plant is used as an adsorbent, a grinding auxiliary and the like, so that the physical characteristics of the distillation residue kind waste for being large in brittleness or prone to viscosity in case of heating are changed, meanwhile, the distillation residue kind waste is effectively prevented from releasing volatile gas with peculiar smell, so that the dangerous solid waste is stabilized, and the volatility and the toxicity of the dangerous solid waste are eliminated; even through the heating value of the modified organic solid waste is reduced, the combustion performance of the modified organic solid waste is remarkably improved, and the added fly ash component alsohas a combustion catalytic effect; and in order to obtain the high-heating-value solid fuel as far as possible, modified distillation residues, coal or waste semi-coke powder are compounded to obtainthe composite fuel capable of meeting the use requirements of industrial boilers in enterprises or parks, so that the purpose of efficient resource utilization of industrial waste is achieved.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of resources, and in particular relates to a treatment method for distillation residue waste and its products. Background technique [0002] Industrial waste has many sources and complex types, and is generally treated in a centralized and decentralized treatment and disposal system. In particular, wastes containing hazardous chemical components that have no clear use or cannot be directly used at all are listed as hazardous wastes for management; and a large number of hazardous wastes with various types and complex sources cannot be used or cannot be provided with safe and proper treatment and disposal technologies. And ways to effectively control and eliminate hazards, it is a great environmental protection challenge for enterprises that produce waste or collect and dispose of it. [0003] At present, the methods of centralized treatment and disposal of hazardous solid waste can be divi...
