Description
Technical field:
The present invention relates to organic solid castoff handles and comprehensive utilization field, particularly reclamation processing method for poor garbage.
Background technology
The alleged poor garbage of the present invention mainly is at without the rubbish after the natural heap garbage of any processing and the envelope factory of landfill factory, the decrement rubbish that compost is ended.
Statistics according to Ministry of Construction's issue in 2002: 1.36 hundred million tons of China's 660 organizational system cities house refuse generations, wherein the amount of focusing on is 7,404 ten thousand tons, there are 6,200 ten thousand tons without any processing, these house refuses or be deposited in the appointed place, or arbitrarily be deposited in river bank, pond and the combination area of city and country.House refuse " besieged city " phenomenon is very serious; County town in addition, 660 organizational system cities, organic town, about 3,600 ten thousand tons of year generation house refuse does not obtain handling substantially, is poured over swag, river bank, lake etc. nearby, environment is caused seriously pollute.By the end of the year 2003, build together and establish 575 in domestic rubbish disposal factory (field) in the whole nation, 7,545 ten thousand tons of disposal abilities, and wherein household refuse landfill sites is 457, disposal ability is 6,404 ten thousand tons, account for 79.5% and 84.5% respectively, 47 of municipal solid waste incinerators, 3,700,000 tons of disposal abilities, account for 8.2% and 4.9% respectively, 70 in consumer garbage compost factory, 7,170,000 tons of disposal abilities account for 12% and 9.5% respectively.
State Environmental Protection Administration investigated 30 province, district and city, 329 domestic rubbish disposal facilities in ground in calendar year 2001, the result: " what meet the sanitary landfills requirement in the household refuse landfill sites substantially accounts for 8.9%; what part met the sanitary landfills requirement accounts for 43.9%; simple and easy landfill yard accounts for 40.5%; " the severe contamination water body does not have essential distinction with untreated dumping.If by 457 disposal abilities of landfill yard in 2002 be 6,404 ten thousand tons 20% the estimation, simple and easy landfill account for 1280.8 ten thousand tons, add in the foregoing organizational system city 6,200 ten thousand tons without any processing, county, town do not obtain 3,600 ten thousand tons in the rubbish handled substantially, the whole nation amounts to: 11,081 ten thousand tons, add the decrement rubbish that composting plant is dropped, this and in recent years the rubbish of other statistics to remain 12,000 ten thousand tons data be approaching.
To the measuring and calculating of landfill waste 14 annual means, the mean calorie of landfill yard poor garbage is at 2800 kilocalories/kg according to Shanghai Lao Gang landfill yard, and 40mm oversize mean calorie is up to 6500 kilocalories/kg, and the energy, the utilization of resources are got up considerable.The organic overwhelming majority stable in the 40mm screenings is difficult for decomposing again, wherein contains the class humic acid substance or claims lignin derivative about about 15%.Except class humic acid substance or the title lignin derivative of the overwhelming majority for being difficult for decomposing again; The heavy metal that also exists a large amount of germs, virus and microbial toxin and be concentrated simultaneously.As directly doing farming fertile meeting contaminated soil and agricultural product.As abandon, can produce secondary pollution, also be the waste of resource simultaneously.China's major part is used as the nutrition soil or the landfill factory overburden soil of trees greening.The developed country that has, only repeats to have reduced the utilization rate of landfill yard as the landfill yard overburden soil no longer as greening nutrition soil for fear of ecological risk.Outside the poor garbage depollution environment, take a large amount of soils, wasted land resource.Through the rainwater leaching, ooze drop liquid and can cause water pollution.The landfill waste that closes has a lot of cities to clear out a gathering place to do after-treatment, so that do the secondary landfill yard, save land used.Continue to select new landfill place, to a lot of cities, not easy.To the processing of poor garbage, significant.If can only handle with burning method with conventional art, the problem of existence is that cost height, investment are big, and serious to the atmosphere secondary pollution, the cost that solves secondary pollution is very high, and is the waste resource.Do not do the poor garbage of any processing, waste land resource, waste regenerative resource resource is wasted renewable physical resources, and continues contaminated environment.
Domestic waste is meant in city dweller's daily life or the solid waste that produces in the activity of service is provided for daily life.China's domestic waste adopts the method for stacking and landfill to handle always for a long time.Stack or the domestic waste of landfill 〉=2 year is called outmoded house refuse at landfill yard.Outmoded house refuse is basicly stableization after degraded for many years, is characterized in that the microbial death body burden is abundant, and content of organics is lower, and ash content is big, and calorific value is low.Domestic waste adopts the method for stacking and landfill not only to pollute environment, has also caused the waste of resource.
Existing poor garbage has only traditional composting technology, relies on adding new refuse or straw kind, industrial organic waste class to carry out aerobic secondary fermentation, and fermentation time is long, has heavy metal and microbial toxin residual.
Chinese patent application number is that 200510090096.6 to disclose a kind of be the method that raw material is produced active nutritional fertilizer with outmoded house refuse, it is for utilizing nitrogen-fixing bacteria, light and bacterium, saccharomycete, lactic acid bacteria, composite bacteria agent capable and earthworm that little aerobic or aerobic bacteria such as functional bacillus is formed, outmoded house refuse being added the rice chaff of 2-5% and the straw of long 30mm ferments as raising agent, the organic component content of the fertilizer that obtains is measured, if can not reach: full nitrogen 〉=0.3%, quick-acting nitrogen 〉=0.04%, full phosphorus 〉=0.1%, full potassium 〉=0.2% o'clock, carry out nitrogen, phosphorus, the balance of potassium promptly adds nitrogenous fertilizer, feed with balanced nutrients such as phosphate fertilizer and potash fertilizer is to reach standard.But it is separated that the heavy metal that is concentrated in the outmoded rubbish does not have, and directly does fertilizer or add fresh organic matter.Carrying out secondary fermentation does fertilizer and all can cause ecological risk.
