Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a sewage treatment control device and a sewage treatment system thereof. Background Art

[0002] With the continuous progress of economic development and urbanization, people pay more and more attention to environmental issues, especially water resources. Most of the used sewage is discharged into the sewage treatment plant through underground pipes. When the sewage is treated in the sewage treatment plant, it needs to go through multiple treatment tanks to make it reach the discharge standard. The sewage treatment control equipment, as the control equipment of the industrial sewage treatment system, makes the operation process of the entire sewage treatment system in treating sewage simpler. Therefore, a sewage treatment control equipment and a sewage treatment system thereof are proposed.

[0003] Sewage treatment control equipment is placed on one side of a sewage treatment pool for a long time. When it is exposed to the outside for a long time, some chemicals in the sewage may evaporate in the gas due to sunlight, so that the sewage treatment control equipment comes into contact with the gas and causes corrosion on the outer surface, which may cause damage to the sewage treatment control equipment in the long term. The heat dissipation ports of existing sewage control cabinets are all integrally formed, and then the opening is tilted downward. Therefore, when the temperature of the control cabinet is high, too large an inclination angle may affect the heat dissipation effect, while too small an inclination angle may cause rainwater to enter the interior of the control cabinet from the heat dissipation port during the rainy season. At the same time, after the sewage is precipitated, the sludge is generally sent to a special landfill for landfill. Although this method is simple, it may occupy land resources and there are problems with leachate and gas emissions. Therefore, according to the above situation, a sewage treatment control device and a sewage treatment system thereof are proposed. Summary of the invention

[0032] 2. The present invention provides a sewage treatment control device and a sewage treatment system thereof. The control device uses a zinc-based coating that is in direct contact with the wall, and improves the ratio of zinc powder to a binder, thereby protecting the control cabinet from rust through sacrificial anode protection. Then, through an epoxy resin coating, the ratio of polyurethane resin, curing agent, and solvent is improved, so that the control cabinet has strong weather resistance and UV resistance, and is more suitable for outdoor use. Finally, through an acrylic coating, the coating is set at the outermost part and the ratio of the components is improved, so that the coating can provide weather resistance and dry quickly. When the acrylic coating on the outer layer of the control cabinet is weathered, it can be re-sprayed, and the rapid drying does not affect the normal use of the control cabinet.

[0033] 3. The present invention provides a sewage treatment control device and a sewage treatment system thereof. The sewage treatment system recycles the sludge in the physical treatment pool and the chemical treatment pool, and then uses the sludge treatment equipment to perform high-pressure anaerobic digestion technology treatment. First, the sludge is concentrated to remove part of the water and reduce the treatment volume. The sludge is then preheated to make the sludge temperature at 50-70°C. The concentrated sludge is then sent to a high-pressure digestion reactor. The pressure of the reactor is adjusted to 2-8 bar.

The module box 12 includes a control and adjustment module, a fault alarm module and a data storage module. The module box 12 includes a control and adjustment module, a fault alarm module and a data storage module, so that the entire sewage treatment system can be better monitored and controlled through some existing technical modules.

[0057] A sewage treatment system comprises an inlet pipe, a physical treatment pool, a chemical treatment pool, a deep treatment pool, a sludge treatment device and a monitoring and management module. The inlet pipe, the physical treatment pool, the chemical treatment pool and the deep treatment pool are all connected in sequence. The sludge treatment device is connected to the physical treatment pool and the chemical treatment pool respectively. The monitoring and management module is arranged on one side of the inlet pipe, the physical treatment pool, the chemical treatment pool and the deep treatment pool. The sludge treatment device adopts high-pressure anaerobic digestion technology, which can improve the overall performance, economy and environmental protection of the sewage treatment system. By being used in large-scale sewage treatment plants, the economy and environmental protection of sludge treatment can be significantly improved. At the same time, the efficiency, energy recovery and environmental impact of sludge treatment are improved, which is conducive to the sustainable development of sewage treatment plants.

[0058] The physical treatment pool uses screen filtration to remove larger solid impurities through mechanical screens. The chemical treatment pool uses coagulation sedimentation to add flocculants to aggregate fine particles into large particles for sedimentation. The chemical treatment pool is equipped with a mixing and stirring mechanism. The solid impurities generated in the physical treatment pool and the chemical treatment pool are transported to the sludge treatment equipment through the impurity pump. The sewage treatment equipment uses high-pressure anaerobic digestion technology. By using physical and chemical methods, it is more convenient to filter and treat the solid impurities in the sewage, and then use the high-pressure anaerobic digestion technology of the sludge treatment equipment to treat the solid impurities. The sludge is first concentrated to remove part of the water and reduce the processing volume. The sludge is then preheated to keep the sludge temperature at 50-70°C. The concentrated sludge is then sent to a high-pressure digestion reactor. The pressure of the reactor is adjusted to 2-8 bar. In an anaerobic environment, microorganisms decompose the organic matter in the sludge to produce methane, carbon dioxide and other gases. The biogas produced in the digestion reactor is then collected and processed to preheat the sludge. The sludge is then processed by a belt filter press and then composted.

[0059] The deep treatment pool uses filters, activated carbon adsorption and membrane separation to better treat the sewage so that it can meet the discharge standards.

[0060] Working principle: Connect the water inlet pipe with the external sewage pipe. When the sewage enters the water inlet pipe, the driving mechanism drives the mechanical grille to move to remove larger solid impurities. Then the sewage enters the chemical treatment pool. Then, by adding flocculants, the flocculants are fully integrated with the sewage through the stirring mechanism inside the chemical treatment pool, and then the fine particles are aggregated into large particles for sedimentation. Then, the sludge in the physical treatment pool and the precipitated sludge in the chemical treatment pool are transported to the sludge treatment equipment through the impurity pump. Then, the high-pressure anaerobic digestion technology is used to treat the sludge. First, the sludge is concentrated to remove part of the water and reduce the processing volume. Then, the sludge is preheated to make the sludge temperature at 50-70℃, and then the concentrated sludge is sent to the high-pressure digestion. In the digestion reactor, the pressure of the reactor is adjusted to 2-8bar. In an anaerobic environment, microorganisms decompose the organic matter in the sludge to produce methane, carbon dioxide and other gases. Then the biogas produced in the digestion reactor is collected and processed to preheat the sludge. The sludge is then treated by belt filter press. The treated sludge is then composted. When deep sewage treatment is required, the sewage is deeply treated by filters, activated carbon adsorption and membrane separation to further remove tiny particles, dissolved matter and adsorbed odors in the sewage. After treatment, it is discharged to a designated location. When treating sewage, a rotatable camera is placed next to each treatment pool, and the information is submitted to the control cabinet 1. Then the staff can view the processing status of each processing pool in real time through the display screen 11 of the control cabinet 1. When the control cabinet 1 is running, the servo motor 307 drives the active disk 310 to rotate, so that the active disk 310 drives the driven disk 311 to rotate through the belt 305, so that the active disk 310 and the driven disk 311 both drive the paddle 306 to rotate, discharge the heat, and then allow fresh gas to enter from the air inlet barrel 7, and then allow the gas to flow inside the control cabinet 1, so as to dissipate the heat of the control cabinet 1. When a part of the heat dissipation component 3 is damaged, the power harness and the heat dissipation component 3 can be removed by opening the movable door 6, and the staff presses the card plate 302 by hand to remove the heat dissipation frame 301 from the heat dissipation slot. 9, and repair the damaged parts. When the discharged hot air is large, the micro electric telescopic rod 314 can be retracted, the connecting rod 313 can be moved downward, and then the receiving rod 312 can be hinged with the connecting rod 313, so that the angle of the louver 309 can be adjusted to be perpendicular to the heat dissipation frame 301 through the receiving rod 312. In the rainy season, the louver 309 can be turned downward away from the control cabinet 1 to block the entry of rainwater. In daily use, the zinc-based coating 201, the epoxy resin coating 202 and the acrylic coating 203 can effectively prevent the control cabinet 1 from being corroded, and the acrylic coating 203 can be set at the outermost part and the ratio of the composition can be changed, so that the coating can provide weather resistance and dry quickly at the same time.When the acrylic coating 203 on the outer layer of the control cabinet 1 is weathered, it can be re-sprayed, and the rapid drying will not affect the normal use of the control cabinet 1.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
