The production of bio-organic fertilizer is an important means of resource utilization of agricultural waste.

Agricultural wastes are rich in nutrient elements and organic nutrients necessary for crop growth, and they can be used as resources to make bio-organic fertilizers, and the organic matter can be mineralized, humified and harmless through the action of microorganisms, so that they can be absorbed and utilized by crops, not only can alleviate the pressure of agricultural waste on the environment, but also can turn waste into wealth and obtain certain economic benefits.

The key control parameters of the process in this link are moisture control and material regulation and formulation technology. After the material is prepared, it is required that the dry humidity is uniform, the moisture content meets the technical requirements, and the optimal moisture content is controlled at no more than 50%.

Moisture control is particularly critical. When the moisture content (<30%) is too low, it will affect the life activities of microorganisms and cannot meet the growth needs of microorganisms; if the moisture content is too high (>60%), it will hinder ventilation and oxygen supply, resulting in anaerobic fermentation.

The temperature is difficult to rise, the decomposition rate is obviously slowed down, and the decomposing time is prolonged. The C/N ratio of the material is controlled at 25:1, so that the nutrients of microorganisms participating in the decomposition of organic matter are in a balanced state, and the growth and reproduction needs of microorganisms are met.

This link of 8 t/h organic manure production plant is carried out in a fermentation tank, and the fermentation period is about 15 days. The comprehensive regulation of its key technical parameters focuses on the control of the fermentation temperature, which directly affects the growth and reproduction of microorganisms.

As a result of the active activity of microorganisms, the temperature can rise to 55-70°C in about 2 days, until it reaches 80°C, and then gradually cool down to reach maturity.

The temperature range of the tank fermentation stage is controlled within the range of 65~70°C. In this temperature range, the mass growth and reproduction of thermophilic bacteria will kill the parasites and pathogenic bacteria in the manure of livestock and poultry to achieve harmless.

Technical requirements, humus begins to form, organic fertilizer reaches initial maturity, and the control parameters are regulated by measures such as microbial oxygen consumption and temperature monitoring.

The key technical control point of this link is that the deep aging organic fertilizer fully meets the technical requirements of decomposing, and the cycle is about 30 days.

The undecomposed organic matter in the first fermentation is further decomposed to become relatively fixed organic matter such as humic acid and amino acid, and the product reaches deep maturity. Through facultative anaerobic and aerobic fermentation techniques, the requirements of decomposing are finally met.

Quality inspection of raw materials, secondary fermentation semi-finished products and finished organic fertilizers before packaging.

The five-point sampling method is used to sample about 200g each time from five different parts, and the total amount of samples is about 1kg for inspection. Only when they meet the product standard requirements can they enter the next biofertilizer production unit process.

The fermented basic material is sent into the silo by a forklift, first crushed by a pulverizer, and then screened by a drum sieve, and the qualified material after screening is sent into the mixing drum.

According to the formula requirements, 1 kg of 20 billion functional bacteria is added per ton of material to make the bacterial content reach 20 million per gram before packaging and storage. Unqualified product are returned to the fermentation tank for further fermentation and decomposition.

The 8 t/h organic manure production plant project canteen is only used as a dining room for employees to bring their own meals without cooking.

The waste gas generated by the project is mainly the dust generated during the crushing of bacteria bags, clinker crushing, and packaging; and the odor generated during the composting process.

The clinker after the bacteria package is broken and composted is crushed (organic pulverizer), screened (drum screener) and packed with trace elements in the deep processing area. Dust is generated in this process, and the main pollution factor is particulate matter.

The project is equipped with a bag dust removal device. The dust generated by the pulverizer and the sieving machine is collected by the gas collecting hood, purified by bag dust removal, and then discharged from the 15m high exhaust pipe.

The fermentation stack in the production workshop of the 8 t/h organic manure production plant project consists of four fermentation areas with a thickness of about 1.5 meters, a width of 4 meters, and a length of 50 meters. The composting process will produce malodorous gases, and the main pollution factors are ammonia, hydrogen sulfide, and methyl mercaptan.

The fermentation area of the project is located in the fully sealed steel structure factory building with a length of 103 meters, a width of 22 meters and a height of 6 meters. The odor generated is collected by the ventilation device, treated and purified by the odor treatment facility, and then discharged from the 15-meter-high exhaust pipe. (Find RICHI on Facebook

The 8 t/h manure production plant project mainly takes the following measures to reduce the impact of noise on the surrounding environment:

• Place the production equipment inside the factory building and use the factory building for sound insulation;
• Select low-noise equipment and set up the base for vibration reduction;
• Sound insulation of factory buildings and greening;
• Strengthen the management of equipment and personnel.

The solid waste generated by the 8 t/h organic manure production plant project is mainly the defective products, waste packaging materials and household garbage generated during the production process.

• Unqualified products: mainly produced in the self-inspection of operators and quality inspection and sampling inspection process. The defective products are general materials and returned to the pre-mixing workshop for processing.
• Waste packaging materials: mainly generated in the process of product packaging and warehousing. The cumulative output of the project is about 0.6t/a. Waste packaging materials are general waste, which will be recycled and reused by the supplier.
• Household waste: The domestic waste generated by the project is about 1.485t/a. Collected and processed by the sanitation department.
• Laboratory waste: The laboratory of this project is mainly responsible for the monitoring of sludge entering the site and the analysis of fertilizer components. The reagents and waste liquid produced by the laboratory are hazardous wastes, and the production volume is small.
  
  The 8 t/h organic manure production plant project has a temporary storage room for hazardous waste , Hazardous waste is collected and temporarily stored in the hazardous waste temporary storage room, and handed over to the local chemical company for disposal.
• Mechanical repair solid waste: The large-scale instruments and equipment of this project are all repaired at the factory, and a small amount of waste engine oil will be generated during the machine repair process of other instruments and equipment. Disposal by local chemical company.
• Car wash wastewater sedimentation sludge: car wash wastewater contains oil, SS and other pollutants, so the sludge needs to be disposed of uniformly, and it will be handed over to the local chemical company for disposal along with the laboratory waste and machine repair waste.

No matter which country you are from, the bio-organic fertilizer processing business is an investment direction that can be considered emphatically.

Bio-organic fertilizer is an important way to improve soil fertility and improve the quality of agricultural products. The original intention of the development and production of bio-organic fertilizers is to integrate the advantages of organic fertilizers and biological fertilizers, which can not only help increase crop yields, but also fertilize the soil, regulate soil micro-ecological balance, reduce the amount of inorganic fertilizers, and fundamentally improve the quality of agricultural products , in line with the direction of global agricultural sustainable development and green agricultural product production.
