Application Of Organic Fertilizer Fermentation Tank in Agriculture

In our daily production and life, a large amount of feces are generated, such as traditional public places, fecal water from farms, wastewater from agricultural by-products processing, and wastewater from agricultural markets. This kind of fecal organic matter has a high content and concentration, and if effective measures are not taken to treat it, it will lead to a persistent odor and serious impact on the environment.
Under strict environmental supervision, the illegal consequences of smuggling are very serious; However, if we want to build facilities that meet emission standards, the investment is huge and the operating costs are high, which is impossible for most of our current situations. A large amount of manure from farms cannot directly irrigate crops (recently, the Ministry of Agriculture and Rural Affairs and the Ministry of Ecology and Environment jointly issued a document banning the direct return of manure to the field), which not only causes extensive deaths of root and seedling burning plants, but also causes environmental pollution by stinky mosquitoes and flies, and may also lead to insect pests. The current treatment measure is to transform the feces into liquid organic fertilizer after harmless treatment by microorganisms. In fact, this technology is already very mature and has been used for many years in developed countries.
It is a headache that duck manure and goose manure with high water content cannot be stacked for fermentation. How is this technology implemented? In fact, it is the technical model recommended by the Ministry of Agriculture and Rural Affairs for "full return of aquaculture manure to the field" and "fertilization of aquaculture wastewater". No matter how much excess fertilizer you need to process, it usually takes only 7-10 days to turn it into a basically odorless liquid organic fertilizer using the following techniques. It can be directly extracted (without adding water) to irrigate crops, trees, and other plants, without burning seedlings (without burning roots), and is rich in probiotics. The cost of treating 1 cubic meter of bacteria is only about 1 yuan, and there is no need for aeration, facilities, and manpower input during the treatment process.
The organic fertilizer fermentation tank adopts a vertical closed structure, which saves floor space and better reduces the area requirements for equipment installation. The organic fertilizer fermentation tank is fully enclosed. The waste gas generated during the fermentation process is treated by the waste gas treatment system and discharged into the tank to eliminate secondary pollution. Centralized treatment of chicken manure in the chicken manure fermentation tank The polyurethane is used as a thermal insulation layer inside the organic fertilizer fermentation tank, which is not greatly affected by the external environment, ensuring year-round fermentation. The fecal liquid contact parts are all made of 304 stainless steel, which is corrosion resistant and has a long service life. In the middle of the organic fertilizer fermentation tank, a polyurethane foam filler insulation layer is added, and the outer wall is supported by thickened steel plates. The transmission design adopts hydraulic drive, with high thrust, which can ensure that the corrosive agent in the tank works under full load, ensuring reliable operation, and low maintenance costs.
