High Temperature Aerobic Composting Technology

The most commonly used treatment of livestock and poultry manure is high-temperature aerobic composting technology, which is a process of using microorganisms to decompose biodegradable organic solid waste into relatively stable humus substances under certain temperature, humidity and pH conditions. High-temperature aerobic composting is an effective way to realize the harmlessness and utilization of organic waste. Its technological process is mainly composed of pretreatment, aerobic fermentation, post-treatment and storage. Its key technologies are mainly pretreatment and aerobic fermentation.

1. Pretreatment

Compost pretreatment is mainly to adjust the moisture, pH and carbon-nitrogen ratio of compost raw materials, and to add microbial fermentation agents to compost raw materials. The initial moisture content of composting feces should generally be 40% to 60%. Too low moisture is not conducive to the growth of microorganisms, and too high moisture will block the gaps in the compost, affect ventilation, lead to anaerobic fermentation, slow down the degradation rate, and prolong Heap time. pH is a parameter to evaluate the living environment of microorganisms, and the most suitable pH in the composting process should be 5.5-8.0. In the composting process, the pH value is generally considered to be a non-important factor, because most bacteria can grow and multiply in the pH range of 5.5-8.0. The carbon and nitrogen balance of compost raw materials is a key factor for the optimal biological activity of microorganisms. The carbon-nitrogen ratio of compost raw materials is generally more suitable between 25:1 and 35:1. The carbon-nitrogen ratio is small, the temperature rises quickly, but the maximum temperature reached by the stack is low; the carbon-nitrogen ratio is large, the maximum temperature reached by the stack is high, but the temperature rises slowly. In actual production, materials such as straw, rice husk or sawdust can be used to adjust the carbon-nitrogen ratio. Composting is a biochemical degradation process in which microorganisms act on organic matter. Microorganisms are the main body of the composting process and the most critical and active components in the composting process. Adding microbial fermentation agents to compost raw materials can accelerate the decomposition and maturity of organic matter in compost raw materials and promote the release of available nitrogen in organic materials.

2. Aerobic fermentation

The aerobic fermentation composting process consists of two stages: primary fermentation and secondary fermentation. The time required for composting operation varies with the carbon-to-nitrogen ratio, humidity, weather conditions, and the type of composting operation and management. Under normal circumstances, the fermentation period is about 9 to 35 days. Primary fermentation refers to the stage from the temperature rising to the beginning of falling, which is the first stage of compost fermentation. Oxygen supply to the compost bed or fermentation unit is usually required at this stage. Oxygen is a necessary condition for the survival of aerobic microorganisms. Sufficient oxygen supply is an important condition to ensure the reproduction and development of aerobic microbial populations, and has an important impact on the composting time and the quality of the final product. SX can provide you with professional equipment for organic waste composting. It is generally believed that the volume content of air oxygen in the compost should be kept at 5% to 15%, and if it is lower than 5%, it will lead to anaerobic fermentation; if it is higher than 15%, the compost body will be cooled, resulting in the survival of a large number of pathogens. At present, the ventilation methods used by organic fertilizer equipment mainly include using power shovel or other special equipment to turn the pile, inserting a ventilating pipe with holes into the dung pile, using high-pressure fans to force ventilation and natural ventilation to supply oxygen, etc. During the primary fermentation process, the temperature of each test point in the stack should be kept at 55-65°C, not higher than 75°C, and the duration should not be less than 5 days. Secondary fermentation refers to the fermentation process in which microorganisms decompose refractory organic matter and fermentation intermediate products at a relatively low speed after the compost undergoes primary fermentation. Ventilation is usually not required at this stage, but regular compost turning should be performed.

How To Control The Temperature In Organic Fertilizer Compost

The temperature, humidity, PH value and C/N ratio of the compost during the fermentation process are important factors affecting the effect of the compost. The temperature during the fermentation process of organic fertilizer can be summarized as follows: the temperature rises steadily in the early stage, the high temperature in the middle part remains moderate, and the temperature decreases slowly in the later stage, and the temperature control directly affects the maturity of organic fertilizer in the later stage.

Today, mainly explain how to control the temperature in the organic fertilizer fermentation

The compost temperature of organic fertilizers is mainly controlled by pile turning and forced ventilation. Here, SX can provide you with processional compost turner. In the early stage of fermentation, even if the temperature of the fermentation is slow or even does not rise, the pile must be turned or ventilated after 48 hours to avoid the formation of an anaerobic environment in the high temperature stage. When the pile temperature is lower than 50°C, the pile should be turned in time (the reduction of oxygen will cause the reaction in the pile to gradually decrease, thereby reducing the temperature), increase the pile temperature, promote the decomposition of organic matter and kill harmful microorganisms. In the late stage of fermentation, once the temperature exceeds 65°C, The pile must be turned in time to prevent carbonization and ammoniation of organic matter. Click here to learn more.

During aerobic fermentation, temperature control is very important. If the temperature is too low, the maturity standard will not be met. If the temperature is too high, the nutrients in the compost will be easily lost. The temperature in the compost is within 30 cm from the outside to the inside. Therefore, the metal rod of the thermometer used to measure the temperature must be longer than 30 cm. When measuring, it must be inserted into the compost for more than 30 cm to correctly reflect the fermentation temperature of the compost. In SX, we also have compost machine with temperature monitor on sale, It is in-vessel fermentation tank.

How to read the compost temperature
1. When reading the temperature, make sure the thermometer goes deep into the pile, leave the thermometer for a while to allow the temperature to stabilize before taking the reading, then move it to a new location (including several locations at different depths from the top edge ).
2. The temperature of the pile depends mainly on the moisture content and chemical composition of the raw material components.
3. There is a certain gradient in the change of fermentation temperature. For the system with bottom ventilation, the highest temperature is about 2/3 of the bottom or higher.

Importance Of Bio Fertilizer Production

The products produced by bio-organic fertilizer equipment are made of fresh chicken and pig manure, without any chemical ingredients. However, chickens and pigs have poor digestibility and can only consume 25% of the nutrients. Feces are discharged, so that the dry product contains nitrogen, phosphorus, potassium, organic matter, amino acids, protein and other components.

Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Fertilizer with fertilizer effect.

1. Advantages of bio-organic fertilizer fermentation process

In the production process of bio-organic fertilizer, it is necessary to effectively control the factors affecting the fermentation of organic waste and the reproduction of microorganisms. The main influencing factors are organic matter content, moisture content, carbon-nitrogen ratio, oxygen concentration, temperature and pH in the composting process On the one hand, through the control of various factors, the carbon-nitrogen ratio, temperature, humidity, pH value, oxygen and other nutrients necessary for the growth and reproduction of various microbial strains are met; on the other hand, different nutrients Fertilizer content can produce different effects. For example, high carbon content can help soil fungi increase, nitrogen can help soil bacteria increase, and calcium has obvious effects on crop disease resistance.
The stench produced by bio-organic fertilizer composting needs to be prevented and controlled to avoid secondary pollution. Adding fermentation agents or fast-decomposing bacteria to the compost can reduce the stench in a short period of time, and the sensory effect is better; or The malodorous gas produced by the composting field is treated with biological deodorization technology.

Things You Need To Focus On About Windrow Composting

The windrow compost turning machine can be said to be the core equipment in the current organic fertilizer production process. It can control the fermentation temperature and the moisture in the stack during the windrow fermentation process. At present, the more advanced compost machines on the market can achieve no dead angle turning, and can complete the composting operation of all materials in one workflow.

So is there anything that needs to be paid attention to in the process of using the windrow compost turning machine to ferment organic fertilizer?

1. Pay attention to the temperature, oxygen content and moisture content in the fermentation raw materials. Temperature, oxygen and moisture are directly related to the windrow fermentation cycle of organic fertilizers and the quality of the finished product. Therefore, special attention should be paid to these three aspects when using a turning machine to ferment organic fertilizers. The purpose of the turning operation is to control the temperature, increase the oxygen content in the material, and reduce the moisture content, but it is also necessary to pay attention not to turn too frequently, so as not to affect the temperature increase in the stack.

2. The stacking should not be too high. When using a turner for fermentation, the width of the windrows can be determined according to the output. The height of the compost should be between 0.8 and 1.5 meters. If the height of the compost is too high, it will affect the air permeability of the raw materials, resulting in oxygen content in the stack. Insufficient amount affects fermentation.

3. Pay attention to the freshness of the raw materials. If the raw materials are stored for too long, anaerobic conditions may be formed. Under the anaerobic state, the organic matter content in the raw materials will gradually decrease, which will affect the quality of the finished products. If such raw materials are used to ferment organic fertilizer, attention should be paid to adding fresh raw materials for adjustment.

4. Pay attention to the turning time of windrow composting. When using a turning and throwing machine for fermentation, it usually takes 10-15 days for the initial fermentation to decompose. The turning and throwing time can be determined according to the temperature in the stack. It is tossed a second time, followed by a second aging and fermentation, usually 3-7 days.

5. Pay attention to the nature of the fermentation raw materials. There are many raw materials that can be used to ferment organic fertilizers, such as grass and wood fragments, crop straw, livestock and poultry manure, etc., but the carbon and nitrogen ratios in different raw materials are different, and the fermentation cycle is also different. To ensure the quality of the finished product after fermentation, targeted adjustments should be made before fermentation, which can be applied after mixing different raw materials evenly.
