Municipal bulk solid waste treatment industrial symbiotic system

Abstract

The invention discloses a municipal bulk solid waste treatment industrial symbiotic system. The system is implemented by dividing a city into a classified collection service area, an incineration treatment service area and a comprehensive treatment service area according to original household garbage treatment modes; in the classified collection service area, kitchen garbage and food market garbage are sent to a biogas power generation plant; dry household garbage and street cleaning garbage are sent to an incineration power generation plant; in the incineration treatment service area, single-stage separation is performed on original garbage, wherein oversize products enter an incineration system and undersize products are sent to a comprehensive garbage treatment plant to serve as landfill cover soil; and in the comprehensive service area, the original household garbage enters two-stage separation, wherein the oversize products enter a derived fuel production line, the undersize products are continued separating, and secondary screening products enter a bioreactor landfill yard. The system has evolvability; all kinds of different solid waste treatment facilities are linked effectively; the comprehensive treatment capacity is improved greatly; the urgency of building garbage treatment facilities is restrained effectively; and environmental pollution and social problems caused by the environmental pollution are reduced.

Description

technical field [0001] The invention relates to waste treatment technology, in particular to an industrial symbiosis system for urban bulk solid waste treatment. Background technique [0002] Different garbage collection and classification methods will have different impacts on the subsequent processing of garbage. At present, my country mainly adopts mixed collection methods, which highlights the disadvantages of traditional processing methods. For incineration, mixed collection means high moisture and low calorific value, which not only affects the incineration working conditions and garbage treatment effect, but also causes a substantial increase in operating costs, as well as a substantial increase in unburned pollutants and harmful substances in the flue gas. For landfills, mixed collection means high leachate production, high greenhouse gas emissions, and high odor, which not only increases operation and maintenance costs, but also causes environmental pollution, espe...

Problems solved by technology

[0004] In order to meet the needs of waste disposal, incineration plants and landfills have sprung up in recent years. These treatment plants (fields) not only need to invest a lot of construction funds, but also become new sources of pollution.

Nowadays, it is difficult to select a new factory (field) site, and it is easy to cause social conflicts in sensitive areas
