Abstract

A system for combined treatment and utilization of various solid wastes comprises a solid waste storage module (1), a sorting and crushing module (2), a drying and incineration module (3), a resource utilization module (4), a curing agent configuration module (5) and a harmless landfill module (6). A material outlet of the drying incineration module (3) is respectively connected with a material inlet of the resource utilization module (4) and a material inlet of the harmless landfill module (6) through a second conveying device; and a material outlet of the curing agent configuration module (5) is connected with a material inlet of the resource utilization module (4) through a third conveying device. The system overcomes the limitation of single technical treatment in material balance and energy balance, fully utilizes the synergistic effect of components in various solid wastes, and has the characteristics of multiple types, low energy consumption and high efficiency. The invention also discloses a method for combined treatment and utilization of various solid wastes.

Description

technical field

[0001] The invention relates to technical fields such as environmental protection, energy, and chemical industry, and more specifically relates to a system and method for joint disposal and utilization of various solid wastes. Background technique

[0002] There are many kinds of solid waste, such as domestic garbage, biomass, general industrial solid waste, hazardous waste, construction waste, polluted soil, etc. are solid waste. According to different classification standards, general industrial solid waste can be further subdivided. According to environmental protection statistical standards, it can be divided into 10 categories such as smelting waste residue, tailings, sludge, red mud, phosphogypsum, desulfurized gypsum, and fly ash.

[0003] Among the many solid wastes, domestic waste incineration, biomass blending and other processes are relatively mature, and have been used industrially in my country for many years. However, the disposal of general in...
