Description
Technical field
The invention belongs to environmental technology fields, are related to comprehensive garbage disposal more particularly to a kind of method for comprehensively treating rubbish.
Background technology
In terms of global point, as economic is grown continuously and fast, living standards of the people improve rapidly, and urbanization process is not
It is disconnected to accelerate, but the environmental problem faced simultaneously is also on the rise, the especially processing of rubbish.How municipal solid wastes are solved
Problem, also one health of the mankind, clean living environment, have caused the great attention in the whole world.China's house refuse production in 2010
Hundred million tons of 1 .58 is measured, the accumulative stockpiling rubbish of surrounding city takes up an area ten thousand mu about more than 80, almost has in 661 cities up to 7,000,000,000 ton
2/3 city is surrounded by rubbish, and serious harm is produced to environment.
Domestic rubbish disposal mode includes mainly the side such as sanitary landfills, burning, compost, pyrolysis and comprehensive garbage disposal
Method.Although wherein filling technically simple maturation, Construction and operation expense is low, and treating capacity is big, needs to occupy a large amount of soils, site
Select Consideration extremely complex, recycling level is low, and there is also certain difficulty for loading embeading percolation liquid and biogas treatment；Rubbish
Burning is that solid waste is carried out to the process of pyrolytic and deep oxidation, has volume reduction, decrement larger, can recycle thermal energy
The advantages that, still, burning secondary pollution is serious, and especially incineration flue gas Zhong bioxin all causes environmental and human health impacts
Harm, some burning disposal projects are because the suspension that is strongly opposed to have to of the common people is built；Garbage compost processing is mainly used in
The higher rural garbage of China's content of organics, straw waste and vast small and medium-sized cities.Although composting technology can effective volume reduction
Decrement, reaches recycling effect, but compost is since there is also many problems, such as adaptability to raw material for the limitation of itself
Difference, heavy metal pollution problem is serious, and composting production sales volume is bad etc..
China's domestic waste be mainly derived from the daily daily life of family life, the food debris of diet, all kinds of devices,
The packaging bag of article, wrapping paper, large quantities of waste paper and textile, old metal etc., component of refuse is complicated, mostly composting.Mesh
Preceding garbage disposal still based on sanitary landfills, is aided with the modes such as waste incineration, compost.Wherein waste incineration is applied to south more
Developed area, and most parts of the north then use landfill disposal rubbish.It is this to handle rubbish only with single treatment mode
The waste disposal method that rubbish or landfill are combined with burning, or can not effectively be directed to garbage property and carry out thoroughly innoxious minimizing
Either recycling level is low or secondary pollution seriously cannot reach good treatment effect for processing.Therefore it needs to be directed to me
State's house refuse characteristic, using novel integrated conduct method, reach the abundant recycling of all the components in rubbish, minimizing,
Harmless treatment.
Domestic waste yield in China's is huge at present, and treating capacity is not caught up with much.The rubbish in present more cities
Landfill yard overload operation, while handling in a manner of landfill rubbish and exist and taking up an area that big, processing speed is slow, percolate processing
The problems such as difficult.Fertilizer made of composting method is bad due to fertilizer efficiency, it is difficult to be acceptable to the market.It is most effective decrement side directly to burn
Formula, but the domestic waste moisture content in China is higher, directly burns extremely difficult, and easy tos produce secondary pollution, it is right
Environment generates very big threat.It is simple to handle rubbish by a certain method, all there is many drawbacks.
Invention content
The present invention proposes a kind of novel method for comprehensively treating rubbish for the problem of traditional garbage processing procedure.
In order to achieve the above object, the present invention is realized using following technical solutions：
A kind of method for comprehensively treating rubbish, includes the following steps:
(1) it pre-processes:Crude waste mixes after stacking dehydration with aging rubbish, and preliminary screening is crushed；
（2）It screens again：Rubbish is divided into inertial-garbage, biochemical rubbish and combustiblerefuse；
（3）Inertial-garbage：Landfill disposal；
（4）Biochemical rubbish：The liquid containing bio protease is sprayed, aerobic fermentation processing is carried out, to protide, the sugar in rubbish
And fruit-vegetable fibre carries out biological decomposition, and organic fertilizer is prepared using the organic matter degradation in rubbish；
（5）Combustiblerefuse：Carbonization processing is sorted to obtain flue gas, pyrolysis oil gas and residual solid, residual solid
Processing, obtains carbon black and ash content.
Preferably, the step（1）In the obtained Leachate site of primary garbage dewatering carry out anaerobe fermentation, obtain natural pond
Gas.
Preferably, the step（3）In inertial-garbage be used as building brickmaking.
Preferably, the step（3）Extrusion forming after middle carbon black deodorization, obtains garbage regenerating fuel.
Preferably, building brickmaking process is as follows：The inertial-garbage sub-elected is entered into inorganic matter brick making system, through excessive
Block is broken, fritter is ground, and is mixed in proportion with cement, curing agent, the pavement brick on trade road is pressed into through mold, or bacterium is added
Wetland water-permeable brick is made in kind and heavy metal absorbent.
Preferably, the step（4）Middle organic fertilizer is incorporated corresponding phosphorus, potassium, nitrogen according to national NY525-2012 standards
Nutrition and trace element are pelletized after mixing, and low temperature drying is prepared into compoiste fertilizer, or is neutralized by spraying, probiotics hair
Ferment, mixing granulation are prepared into biological organic fertilizer after dry.
Compared with prior art, the advantages and positive effects of the present invention are：
1. the present invention realizes the recycling of rubbish, harmless treatment, waste water, exhaust gas in garbage processing procedure are completely eliminated
And waste residue, effectively prevent secondary pollution caused by house refuse possibility.
2. realizing separate waste collection, integrated treatment, the degree that garbage as resource utilizes is improved to greatest extent, is had
Effect shortens process cycle.
