Description
Technical field
The present invention relates to technical field of waste treatment, having is the method for comprehensive utilization of one way of life rubbish.
Background technology
Trash processing way can be generally divided into the several ways such as health burning, burning, compost.Waste incineration, or claim rubbish
Rubbish incinerates, and is the method for a kind of refuse process, by organic substance in incinerating waste material, to reduce Waste volume.Burn and other
High temperature refuse disposal system, is all referred to as " heat treatment ".Can convert garbage into as ashes, waste gas and heating power when incinerating rubbish.Ash
Cinder is made up of the inorganic substances in refuse mostly, generally presents with forms such as the microgranules in solid and waste gas.In a lot of situations, burn
Change heat energy produced by rubbish to can be used for generating electricity, heating.But waste incineration also has operating cost high, and incinerating combustion value is low, waste gas
In carry the shortcomings such as a large amount of pollutant.So carrying out rational pretreatment before waste incineration, recycle its recyclable part
After burn being used for, then can effectively reduce its harm and reduce and burn cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for comprehensive utilization of one way of life rubbish, can realize house refuse
Resource reutilization and reduce its pollution on the environment.
For solve above-mentioned technical problem, the present invention by the following technical solutions:
The method of comprehensive utilization of one way of life rubbish, be house refuse electricity consumption magnetic screening is gone out metallics reclaim after, its
Remaining refuse classification is building waste, organic waste and inorganic refuse, and building waste is used for making insulating brick, and organic waste is through nothing
Evilization is used for making fertilizer after processing, inorganic refuse carries out being mixed for burning electricity generation with coal grain after pulverizing.
Further improvement as technique scheme:

Form sediment, after washing precipitate 3～5 times with water, be dried and be crushed to 80～120 mesh,.
Described make fertilizer process be: by gained filtering residue, agricultural crop straw and cattle manure mixing pile 100～150 centimetres
High stockpile, spreads last layer Testa oryzae, then overlay film at stockpile outer layer, and the temperature controlling fermentation is 60～70 DEG C, and carbon-nitrogen ratio is≤
20, after fermenting 10～20 days, after mixing homogeneously, obtain fertilizer with copper sulfate；Filtering residue after deodorization process, agricultural crop straw, cattle
The weight ratio of excrement, Testa oryzae and copper sulfate is 30～50:50～80:10～30:5～15:1～5.
Described inorganic refuse mixes with the coal grain that particle diameter is 10～20mm after being ground into the granule of particle diameter 1～10mm,
Inorganic refuse is 1:0.05～0.2 with the weight ratio of coal grain.
The invention have the benefit that
Categorized consumer waste is that recoverable metal, building waste, inorganic refuse and organic waste are several by the method for the present invention
Type, and then use different processing modes, metallics can be recycled, moreover it is possible to prepare insulating brick, fertilizer respectively, this
Outward being applied individually to burn owing to having isolated inorganic refuse, the calorific value of burning is higher, it is less to burn the pollutant produced, it is possible to
Realize the recycling of house refuse and reduce the purpose of environmental hazard.
