Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to sewage treatment equipment using a starvation-resistant COD high-efficiency bacterial agent for degradation. Background Art

[0002] Sewage refers to liquid containing various wastes, pollutants and harmful substances. It usually comes from household, industrial, agricultural and urban drainage systems, etc., and sewage usually needs to be treated before it is discharged. Sewage treatment is an important part of environmental protection and public health. Untreated sewage is directly discharged into natural water bodies, which will cause water pollution, destroy the ecological balance and endanger human health. Sewage treatment usually includes physical, chemical and biological treatment methods, among which biological treatment methods use the metabolic activities of microorganisms to degrade and transform pollutants, and biological treatment usually uses bacterial agents for treatment. For example, a microbial agent sewage treatment equipment for farms disclosed in application number CN202310570164.7 uses bacterial agents to treat sewage.

[0003] For biological treatment of some sewage with limited nutrients, starvation-resistant COD (chemical oxygen demand) high-efficiency bacteria are usually used for treatment. The reason is that in an environment with scarce nutrients, these microorganisms can more effectively utilize limited energy and nutrients to maintain their survival and metabolic activities. These microorganisms have low demands for nutrients and can metabolize and grow normally under lower COD concentrations or nutrient conditions, thereby maintaining the ability to degrade organic pollutants. Among them, the degradation of starvation-resistant COD high-efficiency bacteria is mainly aimed at treating the chemical oxygen demand in sewage. The organic matter present in high COD water bodies may have toxic effects on aquatic organisms, affecting the survival and reproduction of fish, algae and other aquatic organisms.

[0004] The existing sewage treatment equipment that uses starvation-resistant COD high-efficiency bacterial agents for degradation usually discharges the sewage into a sewage tank and then discharges the starvation-resistant COD high-efficiency bacterial agent into the sewage, and then allows the sewage and the bacterial agent to mix and process freely in the box or pool. Under certain time and conditions, the bacterial agent will decompose organic matter through metabolic processes and convert it into harmless or easier to handle substances, such as carbon dioxide and water. However, in this process, the bacterial agent will continue to decrease due to its consumption, and the existing equipment usually adds the bacterial agent at one time. In the middle of the treatment, the bacterial agent will not be adaptively added according to the bacterial dosage in the sewage, which will lead to poor efficiency and effect of sewage treatment in the later stage. Summary of the invention

Ring 5610, the inner wall of the degradation cylinder 1 is rotatably connected to two symmetrical rotating rods 5614, the outer wall of the rotating rod 5614 is fixedly connected to a worm wheel 5611 meshing with the worm 563, the rotating rod 5614 is jointly connected to a belt transmission structure 5612, the outer walls of both ends of the two rotating rods 5614 are fixedly connected to a traction rope 5613, the other ends of the traction ropes 5613 are fixedly connected to the top of the rotating ring 5610, the PLC controller is connected to the dual-axis motor 561 and the COD measuring instrument electrical signal to form a control loop.

[0027] The inner bottom wall of the oxygen box 2 is fixedly connected with an air pump 6, the output end of the air pump 6 is fixedly connected with a hollow plate 7, the top of the hollow plate 7 is fixedly connected with a plurality of air outlet pipes 8, the other end of the air outlet pipe 8 passes through the top of the oxygen box 2 and is connected with the degradation cylinder 1, and a first normally closed electromagnetic valve is arranged in each of the air outlet pipes 8. The above structure can provide oxygen in the process of sewage treatment; The outer wall of the degradation cylinder 1 is provided with a feed port, the inner wall of the feed port is provided with a sealing plug 9, the inner wall of the degradation cylinder 1 near the bottom is connected with a water outlet pipe 10, and a second normally closed solenoid valve is provided in the water outlet pipe 10.

[0028] The working principle of the present invention is as follows: First, the sewage is discharged into the degradation cylinder 1 through the feed port, and then it is sealed by the sealing plug 9; After the sewage is discharged into the degradation cylinder 1, the electromagnetic strip 59 is powered off and the electromagnetic block 54 is powered on through the PLC controller. The permanent magnetic plate 52 is adsorbed by the electromagnetic block 54, so that the permanent magnetic plate 52 and the electromagnetic block 54 move synchronously. The buoyancy of the sewage drives the floating plate 55 to float upward, and at the same time, the floating plate 55 drives the electromagnetic block 54 to move upward, thereby driving the permanent magnetic plate 52 to push the bacterial agent upward, and then the bacterial agent is squeezed out of the baffle plate 510, so that the bacterial agent enters the degradation cylinder 1. The sewage height in the degradation cylinder 1 is pre-set to be consistent with the height of the bacterial agent entering the degradation cylinder 1. In this case, the amount of bacteria entering the degradation cylinder 1 can roughly treat the sewage. After the injection is completed (pre-calculated time), the electromagnetic strip 59 is powered on through the PLC controller to close the baffle plate 510, and then the electromagnetic block 54 is powered off, so that the permanent magnetic plate 52 falls, the first normally closed electromagnetic valve is opened, and the feeding pipe 511 refills the bacterial agent into the feeding frame 51; By starting the dual-axis motor 561 and driving the worm 563 to rotate, the sliding rod 564 is driven to rotate, and then the stirring frame 565 and the stirring plate 568 are driven to rotate synchronously, so as to stir and mix the sewage and the bacterial agent in a circular rotation. At the same time, the rotation of the worm 563 drives the worm wheel 5611 and the rotating rod 5614 to rotate, and the other rotating rod 5614 is driven to rotate through the belt transmission structure 5612. The traction rope 5613 is reeled in by the two rotating rods 5614 rotating in the same direction. The reeling in of the traction rope 5613 drives the rotating ring 5610 and the stirring plate 568 to move upward while rotating upward, so as to roll the sewage and the bacterial agent up and down, so that the sewage and the bacterial agent are completely and evenly mixed. Because the dual-axis motor 561 is pre-set to rotate in the opposite direction for the same time after each rotation for a certain period of time (this time is the time for the traction rope 5613 to be completely reeled in, and the reeling time is consistent with the lowering time).

[0029] When the bacterial agent degrades the sewage, the aerobic bacteria (such as aerobic bacteria) in the sewage convert the organic pollutants (such as carbohydrates, fats, proteins, etc.) into carbon dioxide and water through oxidation. This process usually requires the participation of oxygen to form a redox reaction. Therefore, the oxygen in the oxygen box 2 is extracted by the vacuum pump 6 and then discharged into the hollow plate 7, and then the air is discharged into the air outlet pipe 8 through the hollow plate 7. The oxygen is discharged into the bottom of the degradation tube 1 through the air outlet pipe 8, so that the oxygen enters the sewage to provide oxygen for the degradation of the bacterial agent. During the aeration process, bubbles rise from the bottom to the water surface, and the carbon dioxide dissolved in the water will escape as the bubbles rise. In the process of the bubbles rising, the escape of carbon dioxide is promoted by the stirring effect, and oxygen is provided to the water at the same time. Then, the first exhaust pump 417 is started and the gas in the degradation cylinder 1 is slowly extracted through the first exhaust hood 415. The gas is carbon dioxide and oxygen (mainly for extracting carbon dioxide). In the process of oxygen and carbon dioxide being extracted, carbon dioxide is adsorbed by the activated carbon plate 45, while oxygen passes normally. Therefore, as the activated carbon plate 45 adsorbs carbon dioxide, carbon dioxide molecules are adsorbed into the pore structure in the activated carbon plate 45, resulting in an increase in the mass of the activated carbon plate 45, which will squeeze the reset spring 411 to move downward. The amount of carbon dioxide is large, and the elastic coefficient of the reset spring 411 is small. Therefore, the activated carbon plate 45 moves downward after adsorbing carbon dioxide, thereby driving the L-shaped conductive sheet 46 to slide on the resistor plate 47, and the PLC controller The current detection module detects the current passing through the sliding rheostat. When the current decreases within a period of time, it means that the adsorbed carbon dioxide is gradually reduced. There are two situations: one is that the degradation is completed, and the other is that the bacterial dosage is insufficient. Therefore, it is necessary to turn off the dual-axis motor 561 and start the COD meter. The COD in the sewage is detected by the COD meter. When it is detected that the COD has not been treated to a suitable discharge standard, the COD concentration detected by the COD meter needs to be transmitted to the PLC controller. The calculation module in the PLC controller controls the current passed into the electromagnetic plate 57 according to the bacterial dosage required for its concentration. The magnetic repulsion of the electromagnetic plate 57 on the permanent magnet plate 52 further discharges the bacterial agent into the degradation cylinder 1, and then stirs and mixes to continue processing.

[0030] When the activated carbon plate 45 drives the fixed ring 44 and the L-shaped conductive sheet 46 to move to the middle of the resistor plate 47, the adsorption force of the activated carbon plate 45 will gradually decrease with the increase of carbon dioxide. Therefore, when the adsorption force of the activated carbon plate 45 is reduced to the point where it will affect the detection, the activated carbon plate 45 needs to be processed. Therefore, the electromagnetic circular plate 410 is energized through the PLC controller to make the electromagnetic circular plate 410 and the permanent magnetic circular plate 562 magnetically adsorbed, and the elastic telescopic rod 49 is driven to rotate by the dual-axis motor 561, thereby driving the rotating plate 41 to rotate for a certain period of time (the rotation time is the time for the new activated carbon plate 45 to completely replace the old activated carbon plate 45), and then the heating plate is started to heat the replaced activated carbon plate 45. The heating can provide sufficient energy to enable the carbon dioxide molecules to overcome the adsorption force and be desorbed from the surface of the activated carbon. Then, by starting the second exhaust pump 418, the carbon dioxide is sucked out through the second exhaust hood 416 and the air outlet 4111 and discharged into the gas collection box 4114.
