Description
Technical field
This utility model belongs to organic solid waste processing technology field, is specifically related to a kind of organic solid waste pelletize transformation composted and produces the device of granular organic fertilizer.
Background technology
Along with development and the raising of human living standard of industrial or agricultural, the solid waste of generation gets more and more.Having a large portion is organic solid castoff, these organic solid waste moisture content are higher, banking process produces containing high concentration percolate, foul smell, and have substantial amounts of pathogenic bacterium, parasitic ovum etc., so current organic solid waste processing mode the most inevitably brings the problems such as foul smell, environmental pollution, harm human health.And organic solid castoff is the waste resource that a kind of resourcebility utilizes, wherein content of organics is high, has higher economic worth.Therefore, carry out a biological disposal upon therein containing biomass portion, on the one hand decrease the discharge of poisonous and harmful substance, play the effect of Environment control；On the other hand, the material making recoverable is reclaimed to greatest extent with energy and is utilized.
At present, domestic and international organic solid waste processing mode mainly has 3 kinds: fills, burn and carries out a biological disposal upon.Final processing mode as organic solid waste, landfill is widely adopted, although this method is simple, reduced investment, treating capacity are big, but that its shortcoming is floor space is big, secondary pollution is serious, especially in densely inhabited district, expensive land price and local resident are unsuitable for the operation of landfill yard to sanitary requirement；Utilize the mode burned to process solid waste and use more in the area that population density is bigger, the advantage of this processing method is innoxious and the big and rapid volume reduction ability of high temperature, the recycling of the energy can also be carried out, its shortcoming is construction investment and operating cost height, and easily causing air pollution, particularly toxic gas is the biggest on the impact of human body；Compared with front 2 kinds of processing methods, utilize biotechnology to process debirs and have protection environment, save material and the energy, small investment, operating cost are low, economy return advantages of higher.
The biological treatment of debirs is probably the processing mode of most sustainability, and by advanced technical measures, all of biodegradable waste material can be processed by biological mode.Aerobic compost is to mix according to a certain percentage with inserts by the rotten organic materials of heap, under suitable moisture, aeration condition, make microbial reproduction organic matter of degrading, thus produce high temperature, kill pathogen therein and weed seed, make Organic substance reach stabilisation.Biologic treating technique is to utilize biodegradation refuse, can not only obtain can again with fertilizer, moreover it is possible to utilize fermentation time produce heat to refuse heat to reduce its moisture.The process for feces of livestock and poultry that to be scientist Jewell the earliest proposed in 1984, its principle utilizes microbial decomposition Organic substance in composting process, and the energy produced when utilizing fermentation exactly, increases distributing of moisture in feces, plays dry purpose.Chen Tianrong etc. have developed a kind of chicken manure fermenting dried complete set of equipments, utilize this equipment to process 25 ~ 35d by biofermentation, chicken manure water content can be made to be dropped to below 200g/kg by 650g/kg.A kind of granular efficient biologic-organic fertilizer and processing technology have been developed in fourth road, first by livestock manure fermented, then with pulverize after agricultural waste material, scouring of wool leftover bits and pieces compound；Pelletize after humic acids, trace element etc. are mixed；Finally granular material is dried, cools down, sieved, packed products.Yuan steps on a kind of municipal sludge biological drying method of brightness utility model, is municipal sludge and filling adjuvant hybrid reactor to be set to fermentation buttress and carry out aerobic fermentation 7 ~ 9d by continuous turning, and moisture percentage in sewage sludge have decreased to below 30wt%.A kind of Mechanical Method of the utility models such as Liu Jianguo is processed, produces the method and apparatus of granular organic fertilizer to biological sludge; first biological dilute mud addition medicament is washed; with deeply dehydrating sludge comminutor, the organic dilute mud of biology retained after washing once being completed dehydration, concentration, pelletize again, organic granular is dried post-treatment and is become high-qualityparticulate fertilizer.
During rapidly and efficiently aerobic fermentation technology can be applicable to the process of the organic solid wastes such as animal wastes, mud, bed mud, these organic solid wastes all have for viscosity compared with big, moisture content high, porosity is little, oxygen conveying and the water-dispersible features such as difficulty of feeling sleepy.Except making the moisture content of organic solid waste reduce, also to make its rapidly and efficiently aerobic fermentation make organic solid waste become thoroughly decomposed decomposition, eliminate harmful substance therein, become can directly again with resource.But the fertilizer that aerobic compost obtains mostly is powder, it is too fast that powder fertilizer easily dispels, fertilizer efficiency is scattered and disappeared, and therefore fertilizer efficiency is relatively low.By contrast, granular fertilizers have use conveniently, mechanical strength is high, be difficult to the moisture absorption and lump and the fertilizer efficiency feature such as persistently.So existing technology well can not combine biological treatment, rapid draing and partical, and there is the problem such as time length, operation complexity, it is impossible to meet existing demand.
Accordingly, it would be desirable to a kind of new method, it is ensured that can also ferment by high-efficiency aerobic while organic solid waste fast dewatering, and obtain the granular fertilizers of the high fertilizer efficiency that can directly utilize, it is achieved the effective, harmlessization process that organic solid waste is real.
