Abstract
The invention relates to technology for producing an organic fertilizer by using bamboo shoot hulls serving as raw materials through mixed compositing fermentation. The technology comprises the steps of: cutting and crushing the bamboo shoot hulls, performing screw extrusion dehydration on the bamboo shoot hulls, adding fermented ruminant manures into the bamboo shoot hulls, mixing the materials uniformly, and delivering the materials in a trench type fermenter for compositing fermentation; when the temperature of the materials rises to between 60 and 70 DEG C, performing stack-turning on the materials for oxygen supply by using stack-turning equipment, and further dehydrating the materials; in a high-temperature period, performing the stack-turning at least once each day, and after acid content of the extruded juice is adjusted, returning the juice to the composting uniformly; and after the fertilization is completed, according to different purposes, packing the composting directly or packing crushed composting to obtain the organic fertilizer, or performing extrusion granulation on the composting to obtain the organic fertilizer. The technology is simple and feasible, can realize the resource utilization of the waste bamboo shoot hulls, does not generate secondary pollution, and provides a safe and pollution-free fertilizer for agricultural production while solving the pollution problem.
Description
Technical field
The invention belongs to environmental area comprehensive anti-pollution and waste recycling field, relate to a kind of technology that the waste bamboo shell resource is prepared novel organic fertilizer through microbial fermentation.
Background technology
At present, various processing of farm products wastes have become the formidable enemy of environment.But the bamboo shoot shell has huge exploiting potentialities as a kind of renewable agricultural resource of specific form.Bright bamboo shoot processing be the Yangtze valley and on the south 10 surplus a province (district) like the specialty industries in Sichuan, Fujian, Zhejiang.Have equally also that a large amount of bamboo shoot shell processing wastes are discarded, accumulation, septic phenomenon.CN1793068A " waste bamboo shoot shell is converted into the production technique of organic fertilizer " and CN1887822 " organic-inorganic composite bamboo shoot coat fertilizer and working method thereof " patented technology; All from utilizing waste bamboo shell production fertilizer, composite fertilizer's angle to propose the approach of regenerated using bamboo shoot shell resource; " with also farming of farming " has good economical, societal benefits.Bamboo shoot shell abundant nutrients; But wherein fibre content has reached about 73%, and compact structure is difficult for degraded; More than the bamboo shoot shell fertilizer developed in two kinds of patents after using, be difficult to directly utilized as carbon source material and trans-utilization influences agricultural effect by most of microbe in the soil.
Summary of the invention
The objective of the invention is to work out a kind of novel waste bamboo shell that utilizes and prepare fertilizer; It is rich in the ruminating animal excrement material of nutritive ingredient, cellulose-decomposing bacteria and enzyme such as the ight soil of animals such as sheep excrement, cow dung through interpolation, and the biological fermentation under mechanical assistance prepares novel bamboo shoot shell biological organic fertilizer.
The present invention will solve be the bamboo shoot shell fertilizer produced of existing method after using, be difficult to by most of microbe in the soil directly as carbon source material and trans-utilization, influence the problem of agricultural effect.
The objective of the invention is to realize like this: described each raw material and components by weight percent thereof are: 60-80 part bamboo shoot shell; 20-40 part ruminating animal excrement material; Mix the back and under the turning condition, carry out aerobic fermentation, and with the reuse during the fermentation of bamboo shoot shell juice, through the dry bamboo shoot shell fertilizer that obtains of after-ripening.
Described aerobic fermentation process is: after described bamboo shoot shell is pulverized, and extrusion dehydration again, the bamboo shoot shell juice after the dehydration is subsequent use; Dehydration bamboo shoot shell is with after ruminating animal excrement material mixes, the entering biological fermentation process; Treat that temperature rises to 50-70 ℃, continue 5-7 days, add subsequent use bamboo shoot shell juice again, continue fermentation; When heap temperature drops to nearly room temperature from 60-70 ℃, material free from extraneous odour, color become brown, and fermenting process finishes; It is dry that organic materials is moved to the after-ripening of indoor stockyard, becomes bamboo shoot shell fertilizer after pulverizing, sieving.
Described bamboo shoot shell is pulverized to bamboo shoots source mill waste bamboo shell or is collected the bamboo shoot shell, is broken into 2-3cm length with cutting mill.
Described extrusion dehydration is that pulverizing bamboo shoot shell is pushed or other dewatering machine extrusion dehydration with spiral machine, and the juice that obtains is collected subsequent use, and the bamboo shoot shell water cut after the dehydration drops to 55%-75%.
Described ruminating animal excrement material is fermentation excrement material, comprises the ight soil of sheep excrement, cow dung and relevant animal, the product behind biological fermentation, and they are rich in nutritive ingredient and cellulose-decomposing bacteria and enzyme, for the fermentation of bamboo shoot shell provides nutrition and organism of fermentation.
In the described aerobic fermentation process, when the compost central portion temp reached more than 60 ℃, the palpus turning was once a day to twice.
Described bamboo shoot shell juice to pH4-5, in fermentation later stage reuse, so that technology does not have discharge of wastewater, makes the nutrient in the juice get back in the fertilizer again through acidity adjustment; Simultaneously, the volatilization loss that has suppressed fermenting process pH rising and ammonia.
Described after-ripening drying is the after-ripening process of compost, dries naturally to water ratio＜20%.
Advantage of the present invention: the one, high among the present invention to fibre content in the waste bamboo shell; Be difficult for the characteristics that fermentation is decomposed; Add and be rich in the ruminating animal excrement material of nutritive ingredient, cellulose-decomposing bacteria and enzyme such as the ight soil of animals such as sheep excrement, cow dung; Effectively promote the degraded of bamboo shoot case fibre, accelerate fermenting process, improve bamboo shoot shell fertilizer quality; Reduced the cost that adds microbial inoculum again.The novel bamboo shoot shell of two the present invention fertilizer non agricultural chemical residuum of bamboo shoot shell from the raw material own, low cost, the bamboo shoot shell fertilizer of preparation can be widely used in organic fruit and vegetables produce, and guarantees quality of agricultural product.The 3rd, the present invention is novel organic fertilizer from the recycling waste angle with the waste bamboo shell resource conversion.Not only solve Compositions of Bamboo Shoot Shell waste pollution problem, improved bamboo shoots deep process technology level simultaneously, prolonged the bamboo shoots processing industry chain.
