Bio-organic fertilizer fermented compost is aerobic or anaerobic fermentation

First, the basic principles of the natural world, there are many of composting microorganisms oxidation decomposition of organic matter. The use of microorganisms under certain temperature, humidity and PH conditions, the biochemical degradation of organic waste, to form a similar humus soil organic matter as fertilizer and soil improvement. This use of microbial degradation of organic waste is known as biological treatment, generally known as composting. Aerobic composting process change some material composition as shown. Composting organic waste is microbial survival, reproduction material conditions, due to microbial life and some need oxygen, and some do not need oxygen, therefore, play a role in the process according to the requirements of different microbes to oxygen, organic waste composting process can be divided into two kinds of aerobic composting method (high temperature composting) and anaerobic composting. The former are under aerobic conditions by means of aerobic microbial activity so that degradation of organic matter, due to the aerobic composting temperature is generally 50 to 60 degrees, up to 70 to 80 degrees, it is also known as high-temperature composting. The latter is the use of anaerobic fermentation fertilizer production process.

In the composting process, the organic waste in the dissolved organic matter by microorganisms in the microbial cell wall and membrane absorption, solid and colloidal organic matter first attached microorganisms in vitro, secreted by microorganisms extracellular enzymatic decomposition of dissolved substances then penetrate cells. Microbial life activities through its own - oxidation, reduction and synthesis process, a portion of the oxidation of organic matter into simple inorganic substances, releasing energy necessary for life activities, and a portion of the organic matter into nutrients necessary for an organism to synthesize new cellular material, then gradually microbial growth and reproduction of organisms to produce more. Under normal circumstances the use of compost temperature change as compost process evaluation. A complete compost composting process consists of four stages, namely the low temperature phase, medium temperature stage, high-temperature phase and cooling phase. Each stage has a different bacteria, actinomycetes, fungi and protozoa, these microbes on the use of waste organic matter as a food and energy source until a stable humus material so far. 2. Anaerobic Composting Anaerobic Composting is by the action of anaerobic microorganisms under anaerobic conditions to carry out, as shown in FIG anaerobic fermentation due to the product after the liquid form, and sometimes still containing small amounts of pathogens and smelly, so before field application must be sterilized and the biogas slurry spread with a special mechanical spraying, fertilizing plots of land area should be large, so this method is more suitable for large farms use. Further, since the methane produced by the external influence of temperature changes, cold winter in northern gas is low, and thus more suitable for China Southern. Second, the composting process and parameters of conventional anaerobic composting technology field deposition method, this method is not only large area, the accumulation time is long, and low sound level. Modern compost production generally use aerobic composting process, with a high degree of mechanization, large capacity, composting speed, high degree of sound and ease of clean production and so on. Aerobic composting livestock manure usually consists of pre-treatment, primary fermentation (primary processing or primary fermentation), secondary fermentation (cooked fermented) and subsequent processing, storage, and so on and unload. 1, pre-treatment because the moisture content of livestock manure in large (water content is usually 70% to 90%), if not water regulation will be due to poor ventilation while the slow emergence of compost temperature rises, the odor generating capacity, and carrying stirring nor convenient. Therefore, the main task is to carry out pre-treatment moisture content, air permeable materials and C / N adjustment. Also be the way to remove those larger compost material is not suitable as wire, brick, stone, plastic film, rope and other impurities, will affect the future otherwise stirring, ventilation and other processes. 2, a first fermentation of manure fermentation is usually carried out at a particular place fermentation (tank, pond, etc.) or the apparatus, in the composting process and the oxygen inside the compost by stirring and forced ventilation, promote aerobic microbial activity. Because composting, air and soil there are a large variety of microorganisms, so soon after entering the fermentation stage. First microbes decompose organic matter for breeding, to produce water dioxide, generating heat to compost heat up. Decomposition of organic matter depends mainly on the initial fermentation medium temperature microbes (30 to 40 degrees) carried out, as the temperature rises, the most suitable life at 45 to 65 degrees Celsius bacteria gradually replaced the medium temperature microbes. At this temperature, a variety of pathogenic bacteria, parasite eggs, weed seeds, etc. can be exterminated. Usually the temperature began to rise to a temperature begins to drop phase is called a fermentation stage. To improve the sound effect, at least at this stage should be kept for more than 10 days. Under normal circumstances, the stage of 4 to 5 weeks cow dung, pig three to four weeks, about two to three weeks chicken manure. 3, the secondary fermentation composting a secondary fermentation after fermentation to continue composting site, so that once the fermentation has not fully decomposed labile, difficult to break down the organic matter continues to break down, and gradually transformed into comparison stable and mature compost. General secondary fermentation requirements better than the first fermentation strict conditions, stack height can be 1 ~ 2m, as long as there is rain, ventilation can be. In the accumulation process every 1 to 2 weeks to conduct a turning. Secondary fermentation depending on the length of time various types of livestock manure and add moisture regulating material properties, generally compost when the internal temperature to 40 degrees on the performance of the end of secondary fermentation, which can be air-dried and subsequent processing of compost, in general, When pure livestock manure secondary fermentation need a month or so, add a straw and other materials secondary fermentation in two to three months or so, and add wooden materials such as sawdust under the bark, etc. secondary fermentation required That six months or more times. Third, the microbes add extra compost added microbes can accelerate the rapid decomposition of animal manure and straw and decomposed substance, greatly improving production efficiency. However, if the required conditions fail compost, plus more of the microbial fermentation will not achieve results.
