Description

TECHNICAL FIELD

[0001] The utility model relates to excrement and dirt fermentation treatment technical field, concretely relates to an aerobic fermentation excrement and dirt treatment device. BACKGROUND

[0002] Excrement and dirt pollution is a serious environmental problem, excrement and dirt contains a large number of pathogen, parasitic worm, antibiotic residue and high concentration organic matter, if not properly handled, can cause serious pollution to water, soil and air, affect human health and ecological balance. The main treatment method of excrement and dirt is to convert excrement and dirt into organic fertilizer, return to farmland, increase soil organic matter, improve soil structure, reduce the use of chemical fertilizer at the same time, promote the sustainable development of agriculture.

[0003] Excrement and dirt biological fermentation is a harmless treatment method for effectively treating excrement and dirt. Excrement and dirt biological fermentation is a biological technology process of converting livestock and poultry manure and other organic waste into biological fertilizer or biological energy. The process mainly relies on the action of anaerobic or aerobic microorganisms to decompose organic matter under controlled conditions. The aerobic fermentation of excrement and dirt relies on microbial inoculum to decompose and ferment excrement and dirt. The high temperature generated during the fermentation process can effectively kill pathogens and achieve harmless treatment of excrement and dirt. Aerobic fermentation has the advantage of short excrement and dirt treatment cycle and is widely used in excrement and dirt harmless treatment.

[0004] The existing excrement and dirt aerobic fermentation first needs to carry out solid-liquid separation of excrement and dirt, and then directly carries out the solid separation in a shed or open environment. This treatment method cannot well control the temperature and humidity parameters required for fermentation, affecting the treatment efficiency of excrement and dirt. At the same time, excrement and dirt accumulation fermentation is easy to produce harmful gases such as ammonia, hydrogen sulfide and methyl mercaptan. Excrement and dirt contains a large number of pathogenic microorganisms and parasitic worm eggs. Pile fermentation is easy to spread pathogenic bacteria and parasitic worms, increase the types and amount of pathogens in the environment, and endanger human and animal health. Excrement and dirt has strong leaching, can pollute surface water and groundwater through surface runoff, and cause a certain degree of environmental pollution. UTILITY MODEL CONTENT

[0068] The working process of the present application:

[0069] (1) According to the amount of excrement and other factors, determine the size and size of the treatment device. Design a reasonable tank structure to ensure good sealing, ventilation and stability. Plan the position of the feed inlet, discharge outlet 16, ventilation port, etc.

[0070] (2) Choose a suitable site to build the treatment device, ensure that the site is flat, well-drained and well-ventilated. Do a good job of site foundation treatment to ensure that the tank is installed firmly.

[0071] (3) The excrement is transported into the solid excrement tank 1 through the feed inlet. Pay attention to control the feeding speed and amount to avoid overloading in the tank. Use the filter structure 3 to achieve solid-liquid separation.

[0072] (4) Turn on the ventilation equipment to maintain sufficient oxygen supply in the tank. The ventilation volume can be adjusted according to the temperature, humidity and microbial metabolism in the tank.

By introducing oxygen, the growth and metabolic activity of aerobic microorganisms are promoted. Aerobic microorganisms can rapidly decompose organic matter in feces and convert it into stable substances such as carbon dioxide, water, and inorganic salts, thereby reducing the content of organic pollutants. At the same time, during the aerobic treatment process, microorganisms decompose odor-producing substances such as hydrogen sulfide and ammonia, thereby significantly reducing the odor of feces and improving the surrounding environmental quality. Under the action of suitable temperature, oxygen and microorganisms, pathogenic bacteria and parasitic eggs and other harmful organisms in feces can be killed, achieving harmless treatment of feces and reducing the potential risk to the environment and human health. The device can complete degradation in 24 hours, 80% of the solid matter is degraded into organic fertilizer, and no cleaning is required within 2 to 3 years, saving use and maintenance costs.

[0077] The separated solid part is further treated (such as composting) and can be converted into organic fertilizer for agricultural production, realizing resource recycling. The liquid part after treatment can be used for farmland irrigation or standard discharge, reducing waste of water resources and pollution to the environment. The treatment process of the aerobic ecological bin is relatively energy-saving compared with the traditional treatment method, reducing energy consumption. At the same time, through resource recycling, the dependence on external resources such as chemical fertilizers is reduced, achieving the goal of energy saving and emission reduction.

[0078] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

[0079] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the product in use, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0080] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
