Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an industrial wastewater biodegradation treatment device and method. Background Art

[0002] Industrial wastewater biodegradation treatment equipment is a combination of a series of devices and systems specially used to treat industrial wastewater. It utilizes the metabolism of microorganisms to convert organic pollutants in wastewater into harmless substances. Among them, the commonly used treatment equipment is the turntable biofilm wastewater degradation equipment. The turntable biofilm can provide a large surface area, which is conducive to the adsorption and degradation of organic matter by microorganisms, thereby effectively removing organic pollutants in wastewater and improving the effluent water quality. For example, a CIT biofilm turntable reactor proposed in patent publication number CN105461049A increases the contact area between sewage and biofilm and increases the flow rate of sewage on the disc surface, thereby improving purification efficiency and purification effect.

[0003] The existing rotary biofilm wastewater degradation treatment equipment still has the following problems when in use:

[0004] The microbial cells in the turntable carrier adhere to each other and to the surface of the carrier to form a dense community, that is, a biofilm. The microorganisms in the biofilm can decompose and metabolize organic pollutants in the wastewater and convert them into harmless substances. When certain microorganisms in the biofilm grow excessively and dominate, they inhibit the growth and activity of other microorganisms that contribute to the decomposition and detachment of the biofilm, making the biofilm tough and difficult to detach, causing the biofilm on the surface of the turntable to become thicker and thicker. Excessively thick biofilms can cause partial blockage of the treatment equipment, affect the normal flow of water, and reduce the hydraulic performance of the treatment system. In addition, anaerobic areas will appear inside the biofilm, producing some incompletely degraded products, reducing the overall treatment effect and making the water quality of the discharged water worse. When the biofilm becomes thicker and the treatment performance decreases, it can only rely on manual judgment and then scraping it off. When the operator does not scrape off the thicker biofilm in time, the working efficiency of the treatment equipment will be reduced.

[0005] Therefore, an industrial wastewater biodegradation treatment device and method are proposed to solve the above problems. Summary of the invention

[0050] The lower side wall of the detection box 241 is fixedly connected to a sewage pipe 42, and a control valve 43 is provided in the sewage pipe 42 to discharge the waste liquid after detection.

[0051] The operating principle of the present invention is now described as follows: the pretreated supernatant in the pretreatment tank 2 is transported to the degradation tank 1 through the overflow hole 4 and the water inlet 5, the drive motor 71 is started, the drive motor 71 drives the installation shaft 72 to rotate, the installation shaft 72 drives the diaphragm 10 to rotate, and the diaphragm 10 is used to clean the pollutants in the sewage below. There are microorganisms in the diaphragm 10, and the microbial cells adhere to each other and to the surface of the carrier to form a dense community, that is, a biofilm. When the biofilm is immersed in the sewage, the biofilm absorbs organic pollutants in the sewage and absorbs dissolved oxygen in the water film outside the biofilm to decompose the organic matter, so that the microorganisms can reproduce themselves; when the sewage is turned out of the turntable and contacts with the air, the air is continuously dissolved into the water film to increase its dissolved oxygen, and the sewage after biological treatment will be transported to the next process through the outlet 6;

[0052] When sewage is transported to the water outlet 6, under the action of water pressure, the sewage will squeeze the induction plate 111 on the left, causing the induction plate 111 on the left to rotate counterclockwise by a certain angle. The rotation angle of the induction plate 111 is related to the water flow speed in the water inlet 5. The faster the water flow speed, the larger the rotation angle of the induction plate 111. When the induction plate 111 rotates, it will drive the arc rod 112 to rotate together. The arc rod 112 will drive the conductive block 13 to rotate upward by a certain angle, so that the conductive block 13 on the left is in contact with the resistor plate 14 on the left. The conductive block 13 is electrically connected to the external power supply, and the upper end of the resistor plate 14 on the left is electrically connected to the electromagnetic block 17 below. When the conductive block 13 contacts the resistor plate 14 on the left, current will be transmitted to the electromagnetic block 17 below, and the closer the conductive block 13 and the resistor plate 14 on the left are, the more current will be transmitted to the electromagnetic block 17 below. When the upper position is in contact, the smaller the resistance on the circuit of the electromagnetic block 17 below, the greater the current delivered to the electromagnetic block 17 below when the external voltage remains unchanged, so that the electromagnetic block 17 generates a stronger adsorption force, and the electromagnetic block 17 below will attract the permanent magnetic plate 19 below, so that the permanent magnetic plate 19 below drives the connection block 18 and the electric contact plate 20 below to move to the appropriate position on the left. Similarly, when the water flows out of the water outlet 6, the electromagnetic block 17 above will also attract the electric contact block 21 to move to the left to the appropriate position, the electric contact plate 20 below is electrically connected to the PLC controller 22, and the electric contact block 21 above is electrically connected to the external power supply through the PLC controller 22. When the degradation tank 1 enters the sewage for the first time, the PLC controller 22 will control the external current to be delivered to the electric contact block 21 with a delay of one minute;

[0053] When the thickness of the biofilm on the surface of the turntable assembly 7 is within a reasonable range, the flow rates of the water flows on the left and right sides of the degradation tank 1 are the same, the two connecting blocks 18 will move to the left to the same position, the electric contact block 21 will be located between the two electric contact plates 20, and the electric contact plates 20 and the electric contact block 21 will not touch each other. When the biofilm on the surface of the turntable assembly 7 is dominated by excessive growth of certain microorganisms, the growth and activity of other microorganisms that contribute to the decomposition and detachment of the biofilm are inhibited. For example, in some environments, filamentous bacteria overgrow and form a dense network structure, making the biofilm tough and difficult to detach, and the specific signal molecules secreted by the organisms fail to transmit or respond normally, affecting the regulatory mechanism of the formation and decomposition of the biofilm, etc., the biofilm cannot detach normally, and the biofilm will become thicker and thicker. An overly thick biofilm will cause partial blockage of the treatment equipment, affect the normal flow of water, and reduce the hydraulic performance of the treatment system. In addition, anaerobic areas will appear inside the biofilm, producing some incompletely degraded products, reducing the overall treatment effect and making the effluent water quality worse.

[0054] When the thick biofilm blocks the flow rate of water, the sewage flow rate of the water inlet 5 and the water outlet 6 becomes inconsistent. Referring to the above principle, the magnetic attraction of the two permanent magnet plates 19 is inconsistent, and the electric contact block 21 will contact the electric contact plate 20 on one side. The electric contact block 21 is electrically connected to the external power supply at this time, and the electric contact plate 20 is electrically connected to the PLC controller 22. When the electric contact block 21 contacts the electric contact plate 20, an electrical signal is transmitted to the PLC controller 22. After receiving the electrical signal, the PLC controller 22 controls the first water pump 25 and the second water pump 27 to work simultaneously to the set value. At a certain time, the first water pump 25 will transport the sewage treated by the biofilm to the detection box 241 through the vertical cylinder 242, and the second water pump 27 will transport the indigo blue reagent in the storage box 26 to the detection box 241 through the vertical cylinder 242. When the thickness of the biofilm exceeds a reasonable range, the biofilm's treatment performance for sewage will decrease, and the ammonia nitrogen component in the sewage cannot be cleaned to the set concentration range. When the ammonia nitrogen in the sewage contacts the indigo blue reagent, a reaction will occur to generate a blue indigo blue dye, and the equation is NH3+NaClO+3C6H5OH+Na2CO3→C 18 H 14 N3O3+NaCl+3H2O+3CO2, then the PLC controller 22 will detect the substances in the detection box 241 through the color recognition sensor 29. When blue substances are detected, it means that the ammonia nitrogen content in the treated sewage exceeds the standard, thereby judging that the biofilm thickness exceeds the set range, eliminating the problem of inconsistent water flow speeds at the water inlet 5 and the water outlet 6 caused by blockage of certain areas inside the device;

[0055] When the color recognition sensor 29 detects the blue precipitate, the PLC controller 22 will control the linear motor 362 to work, and the linear motor 362 drives the collection bucket 37 to move to the right to the set position, so that the diaphragm 10 is inserted into the groove 38 on the surface of the collection bucket 37, and the delivery pump 301 is started to work, and the supernatant in the pretreatment tank 2 is delivered to the cleaning box 31 through the delivery pump 301. At the same time, the micro electric push rod 34 is controlled to work, and the micro electric push rod 34 drives the piston plate 35 to move to the left to the set position, so that the spray hole 32 is located on the right side of the piston plate 35, and the cleaning port 33 is located on the left side of the piston plate 35. When the supernatant is delivered to the cleaning box 31, the supernatant will be A faster flow rate is sprayed out from the cleaning port 33, and the high-speed water flow is used to clean the thicker biofilm on the surface of the diaphragm 10, so that the biofilm falls into the collecting bucket 37, and the groove 38 is used to scrape the biofilm that has not been washed off on the diaphragm 10. After the cleaning work is carried out for eight minutes, the PLC controller 22 controls the conveying pump 301 to stop working, and controls the collecting bucket 37 to move to the left to the initial position. Then the PLC controller 22 controls the recovery pump 39 to work, and the recovery pump 39 conveys all the cleaned biofilms to the recovery box 41 for storage through the feed pipe 40. Since the rear side of the collecting bucket 37 is tilted downward, the cleaned biofilms can be conveyed to the recovery box 41.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
