Problems solved by technology

With the increase of the years of plastic film cultivation, the amount of residual film in the soil continues to increase, which hinders the penetration of soil capillary water and natural water, affects the hygroscopicity of the soil, and hinders water movement, thereby destroying the soil structure, reducing the level of fertility, and hindering the growth of crops. growth and development, and even cause difficulty in infiltration of groundwater and secondary salinization of soil, eventually leading to a substantial reduction in production

Abstract

The invention provides a solid-waste recycling treating method.The solid-waste recycling treating method includes the steps that surface modifying, inflaming retarding, cement solidifying and strength bonding are carried out, waste circuit board resin powder, waste agricultural film powder and desulphurization gypsum powder are solidified into a composite board at the normal temperature accordingly, and the waste circuit board resin powder with the particle size ranging from 0.5 mm to 5 mm, the waste agricultural film powder with the particle size ranging from 5 mm to 10 mm and the desulphurization gypsum powder with the particle size ranging from 1 mm to 5 mm are subjected to assistant adding, stirred, mixed, solidified at the room temperature, subjected to casting molding, bubble removing and surface treating, demolded and dried to obtain the composite type board.The solid-waste recycling treating method is free of pollution, simple in technology and low in cost, the prepare board is large in practical value, and recycling use of burned petroleum coke dust is achieved.

Description

Technical field: [0001] The invention relates to a solid waste recycling treatment method, which belongs to the technical field of solid waste treatment and recycling 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] The waste circuit board resin material is mainly a mixture of epoxy resin, phenolic resin and glass fiber. The resin material is a thermosetting resin, and the resin and the glass fiber are in a bonded state, which is difficult to separate by physical or chemical methods, and cannot be melted and regenerated. Since these resin materials contain harmful substances such as brominated flame retardants and a small amount of unseparated hea...
