Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment facility with adjustable treatment capacity. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. By adjusting the wastewater treatment volume, the treatment effect of wastewater treatment equipment can be optimized.

[0003] As shown in the reference case "A Combined Complete Biological Rotary Disc Wastewater Treatment System" announcement number "CN217600561U", the wastewater process flow from the primary sedimentation tank to the non-powered biological filtration is all gravity flow, which minimizes the power consumption during operation.

[0004] According to the aforementioned reference materials, in the above-mentioned device, wastewater enters the anaerobic section of the first stage of the biological rotating contact oxidation tank, where total nitrogen and BOD5 are treated. After treatment, the wastewater enters the aerobic section of the second stage of the biological rotating contact oxidation tank for nitrification to remove pollutants such as ammonia nitrogen. The effluent from the aerobic section of the second stage flows by gravity into the nitrification liquid return tank. The nitrification liquid is then returned to the front end of the two-stage biological rotating contact tank by a nitrification liquid return pump for denitrification. The effluent from the nitrification liquid return tank flows by gravity into the coagulation tank, where the wastewater and chemical agents are thoroughly mixed by the agitator, resulting in a coagulation reaction that removes phosphorus-containing pollutants. However, this device has an unsatisfactory effect in regulating the wastewater treatment volume, affecting the treatment efficiency of the wastewater treatment equipment and making it inconvenient to adjust the wastewater treatment volume, thus reducing the effectiveness of the wastewater treatment facility. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a wastewater treatment facility with adjustable treatment capacity.

[0026] In one embodiment, a wastewater treatment facility with adjustable treatment capacity includes a filter box 100, a storage tank 200 installed on one side of the filter box 100, and an adjustment mechanism 300, which is disposed at the bottom end of the storage tank 200 to adjust the wastewater treatment capacity of the wastewater treatment facility. The adjustment mechanism 300 includes a weighing pan 310 disposed at the bottom end of the storage tank 200, a number of evenly arranged support blocks 320 disposed at the top of the weighing pan 310, the support blocks 320 disposed at the bottom end of the storage tank 200, a conveying pipe 330 connected to the bottom end of the storage tank 200, a solenoid valve installed at one end of the storage tank 200, and a filter assembly 380 disposed on the inner wall of the filter box 100.

[0027] It should be noted that the sewage treatment facilities are provided by

[0028] Pool structure: Typically constructed of reinforced concrete, often rectangular or circular in shape for ease of construction and space utilization. The interior of the pool requires waterproofing and corrosion protection to ensure long-term stable operation.

[0029] Aeration system: including equipment such as microporous aerators, aeration hoses and surface aerators, which disperse compressed air into tiny bubbles through fine pores to increase the dissolved oxygen content in the water.

[0030] Mixing device: It adopts a combination of mechanical and hydraulic mixing to ensure that organic matter, microorganisms and dissolved oxygen in wastewater are fully mixed and in contact, promoting the reaction.

[0031] Microbial carriers: usually use novel elastic three-dimensional packing materials, which have a large surface area, long service life, and are easy to attach biofilms, ensuring the survival and metabolism of microorganisms.

[0032] The regulating mechanism 300 can weigh the wastewater in the storage tank 200 through the weighing pan 310, and then detect the flow rate of the wastewater through the electromagnetic flow meter 340. The rotating rod 381 and the stirring rod 382 in the filter assembly 380 can make the wastewater and the neutralizing agent mix evenly. The filter plate 384, the filter layer 385, and the filter screen 386 can filter and purify the wastewater. The regulating mechanism 300 and the filter assembly 380 work together to optimize the wastewater treatment facility without affecting the normal use of the wastewater treatment facility.

[0033] like Figure 2 and Figure 3 As shown, the regulating mechanism 300 also includes an electromagnetic flow meter 340 connected to one end of the conveying pipe 330. The other end of the electromagnetic flow meter 340 is connected to a connecting pipe 350. The other end of the connecting pipe 350 is connected to one side of the filter box 100. Several evenly arranged support rods 360 are fixedly connected to the bottom end of the weighing pan 310. A fixing plate 370 is fixedly connected between one side of the support block 320 and the filter box 100.

[0034] In this embodiment, when sewage enters the storage tank 200, the weighing pan 310 can weigh and measure the sewage in the storage tank 200. The sewage treatment flow rate can be adjusted and controlled according to the needs. Then, the solenoid valve is opened to transport the sewage. The sewage in the storage tank 200 flows from high to low due to its own inertia. When the sewage flows through the conveying pipe 330 to the electromagnetic flow meter 340, the electromagnetic flow meter 340 can monitor the sewage flow rate in real time and control the sewage delivery flow rate. The support rod 360 and the fixing plate 370 can be installed and supported on the weighing pan 310, which can adjust the sewage treatment volume and improve the use effect of the sewage treatment facility.

[0035] like Figure 4 and Figure 5 As shown, the filter assembly 380 includes a rotating rod 381 rotatably connected to one side of the inner wall of the filter box 100. Several uniformly arranged stirring rods 382 are fixedly connected to the outer wall of the rotating rod 381. A motor 383 is installed at the top of the filter box 100. The output shaft of one end of the motor 383 is fixedly connected to the rotating rod 381. A filter plate 384 is fixedly connected to one side of the inner wall of the filter box 100. The filter plate 384 is disposed on one side of the rotating rod 381. Two filter layers 385 are fixedly connected to the middle of the inner wall of the filter box 100. A filter screen 386 is fixedly connected to the other side of the inner wall of the filter box 100.

[0036] In this embodiment, when sewage enters the filter box 100, a neutralizing agent can be added to the sewage through the cover plate on the top of the filter box 100. The stirring rod 382 on the rotating rod 381 is rotated by the motor 383 to stir the sewage and the neutralizing agent. When the sewage passes through the filter plate 384, two filter layers 385 and filter screen 386 in sequence, impurities and harmful substances in the sewage can be filtered and purified, which can improve the sewage treatment effect of the sewage treatment facility.

[0037] Working principle: When sewage is transported into the storage tank 200, the weighing pan 310 weighs the sewage in the storage tank 200 in cooperation with the support block 320. The control system drives the solenoid valve at the bottom of the storage tank 200 to open. The sewage is transported into the filter box 100 through the conveying pipe 330 in cooperation with the electromagnetic flow meter 340 and the connecting pipe 350. The electromagnetic flow meter 340 detects the flow rate of the sewage based on the electromotive force induced when the conductive fluid passes through the external magnetic field. The control system drives the motor 383 to drive the stirring rod 382 on the rotating rod 381 to rotate, which can mix the sewage and the neutralizing agent together. The sewage is filtered and purified by passing through the filter plate 384, the filter layer 385 and the filter screen 386 in sequence.

[0038] It should be noted that the weighing pan 310, electromagnetic flow meter 340, and motor 383 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the weighing pan 310, electromagnetic flow meter 340, and motor 383 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
