Abstract

The invention provides a method for resourceful treatment of industrial solid waste.Welding dust, straw powder and coal chemical crystalline salt are solidified into a composite plate at normal temperature through surface modification, inflaming retarding and cement solidification, and auxiliary adding, stir-mixing, room temperature curing, casting molding, bubble removal, surface treatment, demolding and drying are conducted on welding dust with particle size smaller than 100 microns, straw powder with particle size being 5-10 micrometers, and coal chemical crystalline salt with particles size being 1-5 micrometers so as to obtain the composite plate.The manufacturing process is free of pollution, the technology is simple, cost is low, the manufactured plate is high in practical value, and resourceful utilization of industrial solid waste is achieved.

Description

Technical field: [0001] The invention relates to a resource recovery treatment method for industrial solid waste, which belongs to the technical field of solid waste treatment and resource recovery in the field of environmental protection. technical background: [0002] With the rapid development of my country's economy, the output of solid waste is also showing an increasing trend. The harmfulness of solid waste pollution to the environment and human body cannot be ignored. It directly affects people's lives and seriously affects the environment and human health. [0003] Biomass resources are abundant and cheap, and its utilization has become a global research hotspot. Biomass resources are widely used as fuel, but rarely used as building materials. Biomass contains three main components of cellulose, hemicellulose and lignin, so it has the function of improving and optimizing the performance of building materials and endowing them with new characteristics. [0004] The ...
