Description

Technical Field

[0001] The invention relates to the field of aerobic treatment biotechnology, in particular to an aerobic treatment biosynergistic process. Background Art

[0002] Aerobic biological treatment is a treatment method that uses aerobic microorganisms to metabolize in the presence of oxygen to degrade organic matter and make it stable and harmless. It is currently widely used in organic fertilizer production and sewage treatment projects.

[0003] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide nutrients needed for crop growth and improve soil, but also improve crop quality, increase crop yield, promote high and stable crop yield, maintain soil fertility, and at the same time improve fertilizer utilization and reduce production costs. Full and reasonable use of organic fertilizers can increase crop yields, improve soil fertility, improve agricultural product quality, and increase the effectiveness of soil nutrients. Therefore, promoting the application of organic fertilizers in my country is in line with the requirements of "accelerating the construction of a resource-saving and environmentally friendly society", and is of great significance to promoting the harmonious and friendly development of agriculture and resources, agriculture and environment, and man and nature, promoting the safe and clean production of agricultural products from the source, and protecting the ecological environment. With the improvement of people's living standards, residents' demand for safe, hygienic and pollution-free organic and green food is increasing, and farmers urgently need to apply organic fertilizers to improve the market competitiveness of agricultural products.

[0004] As the level of agricultural modernization becomes higher and higher, organic food has received more and more attention from people; along with it, ecological agriculture has also been paid attention to; because only ecological agriculture can produce ecological food; in this regard, whether in terms of the strength of national policy support or in actual actions, the country has invested a lot of support; it can be said that organic fertilizer will gradually replace other fertilizers in the future and become an essential fertilizer for crop growth.

[0005] Aerobic composting is a biochemical process that relies on the action of obligate and facultative aerobic bacteria to degrade organic matter. The organic material to be composted is mixed with filler in a certain proportion, and under suitable moisture and ventilation conditions, the microorganisms are allowed to multiply and degrade the organic matter, thereby generating high temperature, killing the pathogens and weed seeds therein, and stabilizing the organic matter. In the process of aerobic composting, the soluble small-molecule organic matter in the organic waste is absorbed and utilized by the microorganisms through the cell walls and cell membranes of the microorganisms. The insoluble macromolecular organic matter first attaches to the outside of the microorganism, is decomposed into soluble small-molecule substances by the extracellular enzymes secreted by the microorganisms, and then is input into the cells for use by the microorganisms; through the life activities of the microorganisms (synthesis and decomposition processes), a part of the absorbed organic matter is oxidized into simple inorganic substances and provides the energy needed for the activities, while another part of the organic matter is converted into new cellular substances for the proliferation of microorganisms;

[0006] The time required for the conversion of raw materials into organic matter depends on many factors, but mainly the humidity and temperature of the environment. The better the temperature and humidity conditions are controlled, the faster the digester and aerobic microorganisms will decompose them; the traditional composting process stabilizes within 30 to 60 days and matures within 90 to 120 days;

[0007] In sewage treatment, aerobic biological sewage treatment technology has good effluent quality, so it is mainly used to treat medium and low concentration wastewater or as a follow-up treatment for anaerobic treatment;

[0008] However, the current aerobic treatment biological process cannot monitor the number and activity of bacteria at each stage, making it impossible to adjust the process conditions and the supplement of active bacteria. When used for composting, it is not conducive to shortening the composting time and improving the maturity of organic fertilizer, and it is difficult to improve the quality of organic fertilizer. When used for sewage treatment, the energy consumption is high, which is not conducive to improving the COD removal rate and the effluent quality of sewage treatment technology.

[0009] In view of this, an in-depth study was conducted on the above-mentioned issues, and an aerobic treatment bio-enhancement process was proposed. Summary of the invention

[0010] The object of the present invention is to provide an aerobic treatment bio-augmentation process to solve the existing problems raised in the above background technology.

[0011] To achieve the above object, the present invention provides the following technical solution: an aerobic treatment bio-enhancement process, comprising the following steps:

[0013] Step 2: Add pH regulator to adjust pH value;

[0015] Step 4: By real-time monitoring of various parameters in the first bacterial culture tank, the amount of different nutrient solutions to be added is accurately determined and added;

[0016] Step 5: After the specialized and facultative aerobic bacteria in the first bacterial culture tank reach the specified concentration, they are sent to the second bacterial culture tank for continuous cultivation and storage;

[0017] Step 6: The second bacterial community culture tank is connected to the aerobic biological treatment equipment, and according to the monitoring data of the aerobic link, the high-concentration bacterial community cultured in the second bacterial community culture tank is added to a certain stage of the sewage or composting process in a timely and appropriate amount.

[0018] As a preferred technical solution of the present invention, the pH value in step 2 is adjusted to 7-8.5.

[0019] As a preferred technical solution of the present invention, the pH regulator in step 2 is stored in a medicine box, and the medicine box is connected to the first bacterial culture tank via a medicine delivery pipeline provided with a solenoid valve.

[0020] As a preferred technical solution of the present invention, in step three, the flow rate of the introduced gas is controlled to be 25 to 30 m / s.

[0021] As a preferred technical solution of the present invention, in step three, the stirring speed is controlled to be 200-800 r / min, and the stirring time is 40-60 min.

[0022] As a preferred technical solution of the present invention, in step 4, the temperature, conductivity, oxygen content, pH, and other parameters in the first bacterial culture tank are monitored.

[0023] As a preferred technical solution of the present invention, in step 4, different nutrient solutions are stored in different medicine boxes respectively, and the medicine box is connected to the first bacterial culture tank via a liquid infusion pipeline provided with a solenoid valve.

[0024] As a preferred technical solution of the present invention, the concentration of aerobic bacteria in step 5 reaches 15×10 9 ~30×10 9 cfu / ml.

[0025] As a preferred technical solution of the present invention, when used for the treatment of water bodies such as rivers, lakes and seas in step five, a porous carrier is added to the second bacterial culture tank to provide growth space for the bacterial community and to enrich the nutrients and oxygen of the bacterial community for fixing the bacterial community.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the aerobic treatment biological enhancement process is applicable to various sewage aerobic biological treatment processes and organic waste aerobic treatment processes for producing organic fertilizers, can autonomously cultivate targeted dominant bacterial communities according to different treatment objects, and accurately judge the activity of the bacterial communities by monitoring multiple parameters such as pH value, temperature, pressure, COD, redox potential, oxygen content, etc., and then automatically add the autonomously cultivated bacterial communities to accelerate the aerobic reaction process and improve the reaction degree, shorten the reaction time of aerobic treatment, and improve the process treatment effect. For sewage aerobic biological treatment processes, the COD removal rate can be improved; for organic waste aerobic treatment processes for producing organic fertilizers, the maturity of organic fertilizers can be improved, and the quality of organic fertilizers can be improved. No manual operation is required, and fully automatic control operation can be realized. At the same time, it does not rely on external bacteria or bacterial communities. Whether it is sewage treatment or composting, the treatment process can be shortened by half, which can reduce the investment in the project and the energy consumption in operation, and is worthy of promotion.
