Due to the adoption of the above technical scheme, the present invention provides a method for making fertilizer by fermenting agricultural production waste in closed aerobic sub-high temperature microorganisms for seven days. Overcome the fatal blocking factors of the above-mentioned "technical background" of the existing organic fertilizer production industry. And make the organic fertilizer production enter the era of continuous production line operation with high mechanical automation and numerical control, meeting the requirements of environmental protection, and taking the daily output base as the production capacity.

The present invention establishes a closed fermentation environment by arranging a fermentation gas fairing cover on the fermentation tank body, and the recycling of the fermentation gas can make the temperature of the fermented objects newly placed in the tank rise rapidly (45°C) and enter the fermentation tank. state of fermentation. In the process of fertilizer production, the influence of natural air temperature on the fermentation temperature is avoided, ensuring the realization of seven-day sub-high temperature fermentation fertilizer under perennial natural environment conditions becomes a reality;

Due to the comprehensive effect of the fermentation gas circulation and fresh air distribution system, the fermentation liquid diversion collection system and the remaining fermentation gas recovery and treatment system, the fermented objects fully guarantee the gas (oxygen content: 10-15 %), temperature (fermentation temperature: 45-65°C), humidity (moisture content: ≤35% in the back of the fermentation tank, 40-45% in the middle) and other technical indicators.

At the same time, it also solves the obstacles and problems caused by the excessive moisture in the fermentation process and finished products due to the unstable water content of the fermented objects.

In addition, through the circulation of the fermentation gas, the beneficial components in the fermentation gas are fully saturated in the fermented objects, effectively ensuring the quality of the fertilizer. It avoids the problem of unstable product quality and poor fertilizer efficiency due to long time and nutrient loss in other fermentation fertilizer making processes.

That is, the pollution to the surrounding environment is avoided, and positive economic and social effects are produced.

Because the present invention adopts trough fermentation, once a day, the running operation of turning and throwing machinery makes the fermented object transfer a fermentation tank section unit (whole fermentation tank) from the feed end (front) of the fermentation tank body to the discharge end (rear part). The body consists of seven fermentation tank unit strokes). Therefore, a fermenter segment unit space is vacated at the front of the fermentation tank every day, and fresh fermented materials are placed every day, forming an industrialized continuous production of high-quality organic fertilizers with a daily production base as the production capacity and stable quality. It has completely solved the chaos of irregular organic fertilizer production, unstable fertilizer quality, and even poor quality.

Compared with prior art, the present invention has following advantage:

(1) In the closed fermentation tank, the oxygen content of the fermented object in the sealed fermentation tank is guaranteed to be 10-15% by using the fermentation gas circulation and the fresh air distribution system.

(2) Utilize the fermentation liquid diversion collection system installed at the bottom of the closed fermentation tank to collect and treat the excess and leaked water of the fermented product together with the microbial fermentation secretion in time, so as to maintain good permeability of the fermentation bed.

(3) The residual fermentation gas recovery and treatment system (low-pressure pulse water suction method) installed on the top of the fermentation gas fairing allows the fermentation gas to be fully converted and utilized with zero emissions.

(4) Sub-high temperature fermentation for seven days to make fertilizer. In the closed fermentation tank, the carbon energy of the fermented matter and the biological energy of the compound bacterial agent combine to generate a sub-high temperature, which causes the fermented object to be denatured by heat. Under the action of the active enzyme produced by the fermenting agent, after seven days of decomposition, conversion, and synthesis, the animal manure and other solid wastes are fermented into high-quality organic fertilizers or microbial organic fertilizers.

(5) Make full use of the sub-high temperature gas in the fermented material at the rear of the fermentation tank to rapidly increase the temperature of the newly fermented material at the front, so that the temperature in the fermenter is stable without being affected by the external temperature; during the fermentation process, The effective components in the fermentation gas are saturated in the fermentation material, the loss of nutrients is minimized and the pollution of the surrounding air is avoided.

(6) Use the fermentation liquid diversion collection system to receive the water leaked from the part of the fermented object that exceeds the normal fermentation humidity (45%) and the liquid produced by normal fermentation around the clock to ensure that the fermentation tank is not waterlogged and has good air permeability. Provide a good working environment for the fermentation gas circulation and gas distribution system.

(7) The check valve in the fermentation liquid diversion collection system is automatically closed when the fermentation gas circulation and gas distribution system is started and running, so as to prevent external air from entering the fermentation tank and affecting the operation effect of the entire system. When the fermentation gas circulation and gas distribution system stop working, the check valve will automatically open to resume the normal operation of the system.

(8) The gas distributor in the residual fermentation gas recovery and treatment system injects the collected fermentation gas into the multi-stage adsorption pool and causes the pool water to generate pulse motion and gas-water fusion, and form the raw material of organic liquid fertilizer, eliminating pollution and turning waste into treasure.
