Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biological natural gas and organic fertilizer production, and particularly relates to an anaerobic fermentation synergistic growth promoter preparation device and method. BACKGROUND

[0002] With the increasing production of organic waste, the anaerobic fermentation treatment technology of organic solid waste is widely applied because it can realize the reduction, harmlessness and resource utilization of waste. However, in the actual anaerobic fermentation process, problems such as low fermentation efficiency, slow gas production rate and long fermentation period are often encountered. The main reason is that the growth and metabolism of anaerobic microorganisms are limited by many factors, such as poor biodegradability of the substrate, insufficient nutrients required by microorganisms, and unsatisfactory synergistic effect between microorganisms. At present, in the field of anaerobic fermentation of organic solid waste, the existing technology for preparing the growth promoter has relatively single composition, and mostly only contains basic microbial agents or nutrients, which cannot fully meet the needs of the growth and metabolism of anaerobic microorganisms. For example, some growth promoters only add simple nitrogen, phosphorus and potassium nutrients, and lack consideration of trace elements and biological stimulants required by microorganisms, resulting in insufficient microbial activity and low fermentation efficiency. In terms of preparation device, the existing equipment has low functional integration, and each processing link is independent, lacking effective cooperation. For example, the raw material pretreatment unit, the mixing and stirring unit, the fermentation unit and the post-treatment unit are not closely connected, and the material transmission process is prone to blockage and leakage, affecting the production efficiency and product quality. In addition, the existing preparation method cannot accurately control the fermentation conditions, and lacks real-time monitoring and dynamic adjustment mechanism. In the fermentation process, the key parameters such as temperature and pH value are prone to large fluctuations, which cannot create a stable and suitable growth environment for microorganisms, and the metabolic activity of microorganisms is inhibited, resulting in long fermentation period and low gas production rate.

DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the related drawings. The present application can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0018] Example 1 The preparation method of the anaerobic fermentation synergistic growth agent of the present application comprises the following steps: Step one, the caking raw materials of solid raw material bin are crushed by a crusher, and the liquid raw materials are filtered to remove insoluble impurities, Step two, the crushed solid raw materials are weighed by an electronic weighing bin, and the filtered liquid raw materials are accurately measured by a metering pump according to the formula, Step three, deionized water is prepared in a pure water preparation unit, the deionized water is injected into a dissolution and chelation tank, and the solid raw materials and liquid raw materials in step two are sequentially and proportionally added, and the solid raw materials and liquid raw materials are kept stirring during the feeding process, Step four, after the solid raw materials, liquid raw materials and deionized water are stirred for a period of time, a chelating agent is added, while the temperature is maintained and the stirring speed is controlled; Step five, after the solid raw materials, liquid raw materials, deionized water and chelating agent are stirred and cooled, a plant dispersing agent is added and stirred uniformly to form a transparent brown-yellow mother liquor, Step six, the sub-liquid elements and chelating agent are weighed and added to the heat storage tank, and warm water is added to dissolve them to form a transparent chelate solution, Step seven, the transparent chelate solution in step six is transferred to an ultrasonic chelation kettle, ultrasonic vibration is performed, and a nano-scale chelate solution, i.e. sub-liquid, is formed; Step eight, the transparent brown-yellow mother liquor in step five is transferred to a coupling fermentation tank, low-speed stirring is performed, and auxiliary liquid is sequentially added; Slowly add the sub-liquid to the coupling fermentation tank, increase the rotation speed, form a uniform suspension, complete the fermentation, and complete the production of the synergistic growth agent, Step nine, the auxiliary components in step eight are refined by a high-pressure homogenizer, Step ten, in a ten-thousand-level clean sterile operation table, the gene engineering bacteria are mixed according to the volume ratio, stirred uniformly, and a gene engineering bacteria group suspension is formed, and then the gene engineering bacteria group suspension is divided and packaged into sterile bags by a peristaltic pump filling machine; In step three, the dissolution and chelation tank is started to heat, the stirring speed is adjusted, the materials are sequentially added, and the stirring time after adding the materials is noted; In step four, the chelating agent is heated, added twice, and the interval time is noted, the temperature is maintained, the stirring speed is adjusted, the reaction time is ensured, and an online pH meter is used for detection to ensure that the pH value is stable; In step seven, an activator is added to form a nano-scale chelate solution, and a laser particle size analyzer is used to detect the particle size of the nano-scale chelate solution; In step eight, the mother liquor and sub-liquid are pumped into the coupling fermentation tank, low-speed stirring is performed, and auxiliary liquid raw materials are sequentially added, and the order, time interval and stirring uniformity are noted; The mother liquor, sub-liquid, auxiliary liquid and gene engineering bacteria group are composed of 17-32 parts of mother liquor, 6-12 parts of sub-liquid, 8-15 parts of gene engineering bacteria group and 30-50 parts of auxiliary liquid.

[0019] In this embodiment, the innovative optimization of the formulation system, the replacement of low-cost and high-efficiency components, and the use of plant extracts for the auxiliary liquid components reduce costs and are environmentally friendly. These extracts not only reduce solution surface tension and improve nutrient adsorption efficiency but also serve as a biodegradable carbon source, promoting lignin / fat decomposition and are suitable for high-oil raw materials (such as livestock and poultry manure). Chelation and complexation technologies enhance stability; liquid complexation buffers pH and simultaneously chelates heavy metals, improving system stability. Sub-liquid elements exist in specific chelate forms, avoiding precipitation with H2S, increasing methane production by 15%~25%, and extending stability. The microbial activity protection design, optimized ratio of genetically engineered microbial communities, and independent packaging prevent premature contact with the main liquid, avoiding metabolic competition and solving the problem of easy inactivation in traditional microbial agents. The sub-liquid element chelates are broken down using an ultrasonic chelation reactor, and the auxiliary liquid components are refined using a high-pressure homogenizer to provide specific surface area and stimulate biological activity. A three-step preparation process (raw material pretreatment → main liquid preparation → functional coupling fermentation) is adopted, integrating a PLC. The central control system monitors key indicators such as pH, temperature, particle size (laser particle size analyzer), and viable bacteria count online, achieving fully automated control of the entire process, improving product uniformity, and increasing efficiency by 40% compared to traditional processes. A compound antifreeze and antioxidant agent prevents crystallization at low temperatures, extending the shelf life to 6 months (compared to only 15 days with traditional processes). Natural preservatives replace chemical preservatives, achieving an antibacterial rate of ≥90%, meeting the NY / T 525 organic fertilizer standard and EU organic certification (EC 834 / 2007). For high-carbon (straw) / high-nitrogen (chicken manure) raw materials, the C / N ratio is precisely adjusted by modifying the component proportions. Compared to other methods, it avoids nitrogen excess or ammonia volatilization; for biogas projects, it adds coenzymes (to increase methane production); for liquid organic fertilizer, it improves adhesion, enabling "one agent for multiple scenarios" application. The cost control design uses plant and waste-extracted effective ingredients to replace expensive raw materials, optimizes equipment functional structure, reduces equipment investment and raw material costs, and the heavy metal index is better than the national standard; the production equipment uses anti-corrosion materials and explosion-proof batching scales, and the inner wall of the pipes is polished to reduce residues, meeting food-grade production standards.
