Description

A kind of method that fully utilizes municipal wastes manufacturing organic carbon fertilizer
The present invention relates to a kind of is the method that raw material is made organic carbon fertilizer with rubbish.
At social high speed development, today that population sharply increases, people's life is also being perplexed in the harm of rubbish with being on the rise.Say that from another point of view rubbish, particularly municipal wastes have also become a kind of urgency huge resource to be utilized.To municipal wastes, traditional treatment process generally is to burn and landfill.Burning pollutes the environment, and landfill then can take a large amount of arable lands again, also is simultaneously the waste to resource.
Comprehensive utilization rubbish particularly municipal wastes is made fertilizer, and research topic has become international.That has appeared in the newspapers and led at present has plant composting process, During High-Temperature Composting method, the promptly aerobic dynamic zymotechnique of zymotechnique and high-rate composting that combines with anaerobism.These technology owing to device fabrication costliness, complex technical process, cause the fertilizer cost height of processing in putting into practice, be difficult to wide popularization and application.
The objective of the invention is to propose a kind of is raw material with the municipal wastes, and production technique is simple, and production cost is low, the organic carbon fertilizer manufacturing method that is easy to apply.
The used basic raw material of the present invention is that municipal wastes comprises: (1) organic garbage of city, as the rubbish (except the deleterious chemical industry rubbish) of domestic garbage, construction unit, enterprises and institutions' generation; (2) rubbish that produces of grain system is as reed, Xue, seat, cover the waste of refuse, rice hair and grain processing with mat; (3) charcoal ash is from the high temperature cabonization process of rice husk, mashed faggot, domestic garbage etc.
For the benefit of produce and manage, plant area is divided into east, south, three districts, north, three subregions are established in the Sector East, and two concentration zones, two subregions and central section are established in the South Area, and the North Area then is made up of packaging final prod district and Office Area.
The present invention realizes by following steps:
(1) collection of rubbish thing.
(2) rubbish is carried out science sorting and processing by character: the rubbish such as rice hair, rice husk, mashed faggot and the grain waste that (a) sub-elect grain system, the 70-80% that gets its total amount pours in each subregion of South Area and Sector East and deposits separately, decomposition digest process through 6-18 month, pulverize powder or particulate state reach more than 30% with more than 20% its content organic and humic acid respectively; (b) sub-elect organic garbage of city such as resident's rubbish, building, enterprises and institutions' rubbish, mix, leave two concentration zones of South Area in remaining 20-30% grain waste in (a) etc., decompose, when temperature reached 25-50 ℃, the rubbish thing had 30-50% to become thoroughly decomposed, and pours the central section into.
(3) high temperature cabonization: the concentration zones after the sorting process and each subregion rubbish is mixed with 2: 1 ratio pours the central section into and carry out high temperature cabonization, according to producing season, the adjusting water content is 35-60% (natural sleet and people cooperate for adding water), wherein, winter in summer 35-45%, spring and autumn 45-60% selects bigger rubbish thing such as the ashes of porosity when being mixed, leaf waits and keeps air permeability; With easy resolution produce the rubbish of big heat such as vinasse, the grain waste waits the temperature that improves the central section scrap heap to 100-180 ℃, various rubbish things are decomposed in carbonization rapidly, carry out twice overturning of twice high temperature altogether, the used time of whole process is with deciding 15-30 days summer season, spring and autumn 20-40 days, in 25-50 days winter, observe garbage carbonized thing and be the chocolate particulate state, be i.e. the 80-90% carbide, the optimum regime of 10-20% partial carbonization thing, and carbon-nitrogen ratio (C/N) is 25: 1.
(4) be mixed: the charcoal ash that High Temperature Furnaces Heating Apparatus gets off is deposited for some time earlier, for adding water, pH value is adjusted to neutrality or meta-acid PH4.5-7.0 from strong basicity PH9.0-9.9 by natural sleet and people.By the character of using soil, with three kinds of treated raw materials, the rubbish thing that carbonization is good, become thoroughly decomposed good rubbish thing and charcoal ash are mixed acidity by different ratios, PH4-6, ratio is 2: 3: 1, neutral meta-acid, PH6-7, ratio is 1: 1: 1, alkaline PH8-9.9, and ratio is 2: 1: 3.
(5) raw material that proportioning is good carries out 2-3 screening, for the first time with No. 1 sieve of 25 * 25mm, sieves with No. 2 of 13 * 13mm for the second time, sieves for 8 * 8mm or 6 * 6mm No. 3 for the third time.Purposes according to production fertilizer is determined screening technology, and fruit tree fertilizer, land for growing field crops fertilizer is with 1, No. 2 sieve, and genseng fertilizer, grow seedlings fertilizer and flower fertilizer sieve with 1,2, No. 3.Screen underflow is gained fertilizer, and screen overflow is participated in once more and become thoroughly decomposed and high temperature cabonization.
(6) the remaining brick of refuse classification, stone, glass are broken into powder with ball mill, add the deficiency that fertilizer replenishes its mineral and trace element, the screening fertilizer well that is mixed is had bad luck the packaging final prod district of North Area with dump truck or walkie fork lift truck.
(7) adding water, to adjust the water content of fertilizer be 30-35%, it was fermented rapidly 1-3 days once more and reach normal temperature, as the carbonic acid smell produce and after testing the fertilizer component content must reach or be better than relative national standards, reach enterprise's standard of dispatching from the factory simultaneously and can pack out finished product.
Key problem in technology of the present invention is the high temperature cabonization zymotechnique, can take three kinds of methods: 1) the high temperature carbonization stove solves the garbage carbonized and generation charcoal ash of a part; 2) at central section high temperature cabonization part rubbish; 3) burn mashed faggot or domestic garbage at the underground carbonization warming chamber of setting up, stack the rubbish for the treatment of high temperature cabonization on the ground, and set up spiral fashion so porous smoking room pipeline (reinforcing bar and screen cloth are made), from the carbonization warming chamber cigarette is drawn on the ground, temperature and the absorption carbonic acid gas of supplying with the rubbish thing of over-ground part increase organic carbon, and, improve along with increasing of scrap heap the smoking pipeline coiled positive cone bodily form.The rubbish thing should be piled equably around the smoking pipeline of over-ground part.The 20-30% of the grain system rubbish that sub-elects is a first layer, and the 20-30% of enterprises and institutions' organic waste is the second layer, and the 70-80% that increases rubbish things such as putting surflaes, stove carbon again is the 3rd layer, and every layer thickness is 30-50 centimetre.Rubbish becomes the chocolate particulate state and promptly finishes carbonization, pours the proportioning district into and is mixed.Can increase the treatment capacity of rubbish by above technology, several method is used simultaneously, also is the active and effective technical scheme that guarantees and improve the fertilizer quality of being produced.
The technological process of production is seen accompanying drawing 1, and accompanying drawing 2 is plant area's orthographic plans.
Process conditions of the present invention can change because of the purposes of fertilizer, thereby produce a series of product: Ginseng fertilizer, fruit tree fertilizer, industrial crops fertilizer, paddy rice, grow seedlings of vegetable and Honda fertilizer, the city Greening fertilizer and three class acidity, alkalescence, neutral subacidity Fertilizer combination, it is suitable that the present invention is had With property characteristics widely.
The product of producing with the present invention is organic carbon fertilizer, organic matter and content of humic acid, Major Nutrient The content of elemental nitrogen, phosphorus, potassium all is higher than national standard, and harmful toxic matter content then is lower than country's mark Standard, and contain abundant trace element, examine according to the land for growing field crops fertilizer of national standard centering meta-acid Survey, the results are shown in Table 1. Popularization application result through for many years proves that organic plain fertilizer has all kinds of crops Significant the effect of increasing income, and connect and executed 3 years was not applied fertilizer and still can be increased production on the 4th year. Simultaneously can also Improve the seed quality, improvement soil, culture fertility, strong stress resistance is used for development flowers cause and vegetables The industrial crops such as dish protection ground year training and fruit tree, cigarette tea, American Ginseng more have its outstanding advantage.
