Description

Technical Field

[0001] The invention relates to the technical field of anaerobic biological treatment, in particular to an anaerobic biological treatment process combining ceramic membrane pretreatment with a magnetic method and a heat preservation system. Background Art

[0002] The role of magnets in the crystallization of calcium carbonate is a field of scientific research that involves the interaction of physics and chemistry. Magnetic treatment is considered to be a pollution-free, low-cost physical anti-scaling method; magnetic treatment can promote the homogeneous nucleation of calcium carbonate, making the resulting crystal particle size smaller and more numerous, and increasing the total deposition amount. When the amount of treated water is small, the magnetic treatment effect is better, but as the amount of treated water increases, the effect of magnetic treatment will weaken. Magnetic treatment changes the structure of water molecule clusters, thereby affecting the formation and dehydration process of hydrated calcium carbonate, the precursor of calcium carbonate crystal nuclei, and further affecting the crystal formation rate and crystal structure. Magnetic treatment may change the crystal form and morphology of calcium carbonate crystals, affect the hydrogen bonds between water molecules, and increase Ca 2+ and HCO3 - The crystallization process is affected by changing the collision probability of the double electric layer and the charge distribution in the double electric layer. Studies have shown that magnetic treatment inhibits the formation of crystals, there is an induction period, and the crystallization rate is 75% lower than that of solutions without magnetic treatment. In the case of calcium carbonate crystallization, the crystallization core provided by magnetic treatment acts as a seed and changes the place where crystallization takes place. These conclusions show that the role of magnets in the crystallization of calcium carbonate is multifaceted, including promoting nucleation, changing the crystal structure, affecting the crystallization rate, etc., but the specific effect may be affected by many factors, including the strength of the magnetic field, the amount of water treated, and the specific conditions of the magnetic treatment.

[0003] At present, the wastewater treatment method is usually to add chemical agents to change the physical and chemical properties of the dirt in the wastewater, so as to change its solubility or generate water-soluble compounds to prevent it from depositing in pipes and equipment and causing blockage. However, the use of chemical agents has problems such as high cost, environmental pollution and equipment corrosion. The use of magnetic fields can effectively solve these problems.

[0004] The functions of setting up an insulation system are: (1) shortening the startup time. During the startup process of the EGSB reactor, insulation helps to shorten the startup time because microorganisms can grow and reproduce faster at a suitable temperature; (2) enhancing system stability. Insulation helps to reduce the impact of external temperature fluctuations on the internal environment of the reactor, thereby enhancing the stability of the system; (3) improving the ability to resist shock loads. Insulation can reduce the impact of temperature fluctuations on the reactor and improve the reactor's adaptability to changes in organic loads; (4) saving operating costs. Through insulation, the EGSB reactor can maintain a suitable operating temperature at a lower energy consumption, thereby reducing operating costs; (5) optimizing the microbial environment. Insulation helps to provide the best growth environment for anaerobic microorganisms, thereby optimizing the activity and treatment effect of microorganisms; (6) reducing energy consumption. Through insulation, the energy consumption required for heating or cooling can be reduced, especially under extreme climatic conditions; (7) extending the life of the equipment. Suitable temperature conditions help to reduce the thermal stress of equipment materials, thereby extending the service life of the equipment. Insulation is an important aspect in the design and operation of EGSB reactors and helps to improve the efficiency and reliability of the entire system. Summary of the invention

[0026] 1. The present invention provides an anaerobic biological treatment process that combines ceramic membrane pretreatment with magnetic method and insulation system. By passing the water pipe through a cylindrical magnet and winding it around the cylindrical magnet several times, the three-phase separation liquid of food and kitchen in the water pipe is magnetized, which can effectively reduce the deposition of dirt in pipes and equipment, thereby extending the service life of pipes and equipment and reducing their replacement frequency; reducing the use of chemicals, reducing costs, and avoiding environmental pollution. By using a magnetic field strength of 0.5 to 2T, dirt in the water can be efficiently removed to avoid clogging pipes and equipment, thereby causing potential harm. The magnetic field of the magnet magnetizes the three-phase separation liquid of food and kitchen, prompting calcium ions to generate calcium carbonate crystals that are not easy to deposit, reducing the resistance in the treatment process, saving energy consumption, and reducing operation and maintenance costs.

[0027] 2. The present invention provides an anaerobic biological treatment process that combines ceramic membrane pretreatment with a magnetic method and an insulation system. The insulation system is set to maintain a suitable operating temperature, because the growth and metabolic activities of anaerobic microorganisms need to be carried out within a certain temperature range. Usually, the most suitable temperature range for medium-temperature anaerobic reactions is 35-38°C. At the same time, at a suitable temperature, the metabolic rate of microorganisms is accelerated, thereby increasing the degradation rate of organic matter and the production of methane. Suitable temperature is also conducive to the formation and stabilization of anaerobic granular sludge, which is the key to the efficient operation of the EGSB reactor. In different seasons and climatic conditions, the insulation system can ensure the stable operation of the EGSB device, especially under low temperature conditions, insulation is particularly important. The insulation system is a key component to ensure the stable and efficient operation of the EGSB device, and is crucial to maintaining the continuity and efficiency of the anaerobic treatment process.

[0028] 3. The present invention provides an anaerobic biological treatment process that combines ceramic membrane pretreatment with a magnetic method and an insulation system.

[0032] See also Figure 1-Figure 2 , the present invention provides two technical solutions:

[0033] The first embodiment: an anaerobic biological treatment process combining ceramic membrane pretreatment with magnetic method and thermal insulation system, comprising;

[0034] Step 1: Environmental data collection: Before the equipment is installed, water quality sampling is required for the water source to be treated, and the installation position of the device is adjusted according to the water quality and the particles inside the water source;

[0035] Step 2: The equipment includes sewage pretreatment equipment, strong magnetic treatment equipment, insulation system, EGSB reaction equipment, and intelligent discharge equipment.

[0043] The thermal insulation structure is composed of asbestos board, thermal insulation foam and polymer heat-resistant material, and the asbestos board, thermal insulation foam and polymer heat-resistant material are processed and compounded by a composite processing method, so that the asbestos board, thermal insulation foam and polymer heat-resistant material form an integrated thermal insulation structure;

[0044] Asbestos board and thermal insulation foam have high heat insulation effect, which can ensure the internal temperature requirement of the device and avoid the temperature leakage of the device caused by the temperature exchange between the water source inside the device and the environment. The high heat-resistant polymer material has high heat resistance effect, which can insulate the heat generated by the heating equipment.

[0045] The magnet of the strong magnetic treatment equipment adopts a hollow cylindrical magnet. The outer diameter of the inlet and outlet ends of the hollow cylindrical magnet is 0.5 cm, and the outer diameter of the main body section is 6 cm. The wastewater pipe passes through the hollow cylindrical magnet and circles around the cylindrical magnet for several times. The flow direction of water is the direction of cutting the magnetic flux lines.

[0049] S3, placing the porous ceramic membrane to be cleaned into the reaction solution, controlling the immersion time according to the degree of contamination of the porous ceramic membrane, and stirring the reaction solution with the aid of external auxiliary equipment, so that the contact area between the porous ceramic membrane and the reaction solution is increased;

[0053] The effluent is transferred through a transfer box, and the water source containing anaerobic organisms is detected by using it in conjunction with a water quality detector, so as to obtain the value of anaerobic organisms in the water source, and then the first solenoid valve tube and the second solenoid valve tube are energized by the controller, the first solenoid valve tube is energized to open, and the second solenoid valve tube is energized to close, so that the effluent containing anaerobic organisms that does not meet the discharge standards is transported to the inside of the delivery pump, and the water source is transported to the inside of the device through the first solenoid valve tube by the delivery pump for circulation;

[0054] The second implementation mode is mainly different from the first implementation mode in that: in step one, sampling is performed using an automatic sampler: when sampling is performed using an automatic sampler, the water sampling pipe should be controlled to sink to a specified depth, and a corrosion-resistant screen with a mesh size of 2 mm should be installed near the tip of the pipe to prevent impurities from entering the pipe and the pump.
