Abstract
The invention relates to a technology for anaerobic fermentation of facility agriculture garbage into a fertilizer. The technology mainly comprises the following steps of: collecting the facility agriculture garbage, crushing the garbage, putting the crushed garbage into an anaerobic tank, performing anaerobic fermentation of one cycle, and preparing solid-state fermentation residues into the fertilizer. The technology breaks through the defects in the traditional stacking and landfill treatment, and converts the facility agriculture garbage into the fertilizer by anaerobic fermentation, so that efficient recycling of the facility agriculture garbage is realized, the industrial chain of the facility agriculture garbage is expanded, and the resource utilization link is prolonged; and the technology is an effective measure for treating rural pollution and improving rural landscape, gives a powerful push to rural circular economy, and takes economic benefits, social benefits and environmental benefits into consideration.
Description
Technical field
The present invention relates to a kind of industrialized agriculture garbage anaerobic fermentation and become fertilizer technology.
Background technology
In recent years, along with China's agricultural structure is adjusted, the industrialized agriculture cultivated area enlarges day by day, mainly plants cash crop such as greengrocery, flowers class, because the industrialized agriculture plantation has characteristics such as output height, multiple crop index height, its economic benefit is very remarkable.The also a large amount of industrialized agriculture rubbish of output---the straw that multiple cropping stays when but industrialized agriculture is planted in and brings economic benefit to people.According to relevant investigation data presentation, China's industrialized agriculture refuse treatment rate only is about 4% at present, most industrialized agriculture rubbish are being stacked near the industrialized agriculture booth or spacious place disorderly, these straws of arbitrarily being stacked are putrid and deteriorated gradually after exposing to the weather, contaminate environment not only, also destroy the whole view in rural area, how effectively processing and these industrialized agriculture rubbish of recycling become the significant challenge on China's agricultural sustainable development road.
Meanwhile, China's stalk marsh gas has obtained fast development in recent years, straw is good organic fertilizer through the product behind the anaerobically fermenting, prove after testing: straw is behind the process anaerobic fermentation process, except carbon, hydrogen, elements such as oxygen are decomposition and inversion progressively, generate methane at last, outside the gases such as carbonic acid gas, all the other various nutrient elements substantially all are retained in the fermentation residuum, wherein a part of water-soluble substances is retained in the liquid of natural pond, another part does not dissolve or difficult decompose organic, inorganic solid substance then is retained in the slag of natural pond, has also adsorbed a large amount of solubility available nutrient on the surface of fermentation residuum.So the natural pond slag contains more comprehensive micro-complex element and abundant organic substance, the essential nutrient contents in the slag of natural pond has: 30%～50% organic matter, 10%～20% humic acid, 0.8%～2.0% full nitrogen (N), 0.4%～1.2% full phosphorus (P), 0.6%～2.0% full potassium (K).If the fermentation residuum is utilized, will be extraordinary fertilizer.
Summary of the invention
The purpose of this invention is to provide a kind of industrialized agriculture garbage anaerobic fermentation and become fertilizer technology, this technological breakthrough traditional stack retting and the landfill defective in disposing, make industrialized agriculture rubbish be converted into fertilizer by anaerobically fermenting, thereby realized the recycling of industrialized agriculture rubbish, be one and promote agricultural sustainable development, administer the effective measure that the rural area is polluted, improved Rural Landscape, take into account economic benefit, social benefit and environmental benefit.
The objective of the invention is to realize based on following steps: this industrialized agriculture garbage anaerobic fermentation becomes fertilizer technology to finish according to the following steps:
(1) with unified depositing after the industrialized agriculture refuse collection, with machinery or manual mode straw is shredded, the straw length after the chopping is controlled between 1～5 centimetre.
(2) bottom percolate and the crushing straw of getting anaerobic fermentation tank before the charging mixes, in the anaerobic fermentation tank of subsequently mixture being packed into.
(3) adopt mesophilic digestion technology in the anaerobic fermentation tank, after the processing through a fermentation period (about 30 days), its percolate flows out the inoculation feed liquid of fermentor tank as the next batch material, and that the straw that has fermented is pulled out is standby.
(4) straw after the fermentation can directly be applied to the farmland after draining, or sells as fertilizer through processing metering encapsulation back.
This industrialized agriculture garbage anaerobic fermentation becomes fertilizer technology, and its described " rubbish " is generalized, in the general reference industrialized agriculture production process because the discarded plant body that multiple cropping produces part or all of.Industrialized agriculture rubbish refers to plant residue part discarded with plant recovery process such as vegetables, flowers or that sales process is remaining, as the remaining not high part of economic worth in farmland vegetables, flowers results back, also comprise non-lignified plant materials parts such as part waterplant outside vegetables, the flowers and weeds simultaneously.
The present invention compares with prior art stack retting and landfill technology and has the following advantages:
1) the present invention utilizes industrialized agriculture rubbish to produce organic fertilizer, is the efficiently utilization again to industrialized agriculture rubbish, has expanded the industrial chain of industrialized agriculture rubbish, has prolonged utilization of resources link, is the strong promotion to the rural area recycling economy.
2) the industrialized agriculture rubbish behind the anaerobically fermenting can substitute the most of raw material in the existing organic fertilizer owing to contain macronutrient, effectively widens the raw material sources of organic fertilizer, has significantly reduced its tooling cost.
3) main raw material of fertilizer is an industrialized agriculture rubbish, and itself belongs to crop material, and content of cellulose is higher, can effectively improve soil physico-chemical characteristic after later stage and soil fusion.
4) the industrialized agriculture garbage raw material through anaerobically fermenting, wherein is harmful to germ and is killed basically during the fermentation, has effectively controlled the disease and pest propagation, has also reduced the probability of occurrence of disease in the plant subsequent growth of utilizing this substratum.
5) the present invention helps Economic development and environment protection, is the effective behave that effectively advances China's new countryside construction.
