Description
Technical field
The present invention relates to technical field of waste treatment, having is the preprocess method before one way of life waste incineration.
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.Waste gas is being discharged into
Before in air, needing to remove wherein dusty gas and microgranule, remaining residue is then for landfill.In some situation, incinerate rubbish
Heat energy produced by rubbish can be used for generating electricity, heating.But waste incineration also has operating cost high, and incinerating combustion value is low, takes in waste gas
Carry the shortcomings such as a large amount of pollutant.So carrying out rational pretreatment before waste incineration, it is possible to effectively reduce its harm and reduce
Burn cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide the preprocess method before one way of life waste incineration, to reduce rubbish
Burn the harm produced.
For solve above-mentioned technical problem, the present invention by the following technical solutions:
Preprocess method before one way of life waste incineration, be carry out house refuse tearing up, after broken bag processes, screening
Going out metallics and reclaim sale, remaining refuse classification is organic waste and inorganic refuse, and organic waste is after harmless treatment
For making fertilizer, for burning electricity generation after mixing with coal grain after inorganic refuse pulverizing.
Further improvement as technique scheme:
The method of described screening is preferably electromagnetism screening.
The process that described harmless treatment processes is: is put into by organic waste in the water of its weight 2～3 times, regulates pH value
Regulation is to 9～11, and continuous aeration processes 12～24 hours, is stirred continuously organic waste, then filters in aeration process, and filtering residue is used
In making fertilizer, filtrate puts into the heavy metal scavenger of its weight 0.1%～1%, under conditions of being stirred continuously react 30～
60min, is subsequently adding flocculant flocculation sediment, and gained supernatant is reused for carrying out mixed processing with new organic waste.
Wherein, the preparation process of described heavy metal scavenger is: add iron chloride, aluminum chloride and manganese chloride, system in water
Iron concentration be 0.5～1mol/L, aluminium ion concentration be 0.8～1.2mol/L, manganese ion concentration be 0.1～0.5mol/L
Mixed solution, in the case of being stirred continuously, add sodium hydroxide solution regulation to pH value be 7～8, stand clarification after take heavy
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.
Wherein, the weight ratio of filtering residue, agricultural crop straw, cattle manure, Testa oryzae and copper sulfate after described deodorization processes is preferably
40:65:20:12:3。
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
The method step of the present invention is simple and easy to control, is recoverable metal, inorganic refuse and organic rubbish by categorized consumer waste
Rubbish several types, and then use different processing modes, metallics can be recycled, moreover it is possible to prepared heavy metal free pollution,
The fertilizer that fertilizer efficiency is good, is applied individually to burn additionally due to isolated inorganic refuse, and the calorific value of burning is higher, burn generation
Pollutant are less, it is possible to realize the recycling of house refuse and reduce the purpose burning harm.
