Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated water treatment device operating in low dissolved oxygen mode. Background Technology

[0002] Low-dissolved oxygen water treatment refers to the use of various technologies to reduce the dissolved oxygen content in water bodies to achieve specific treatment effects. Simply put, low-dissolved oxygen water treatment is a method that alters the aquatic environment by reducing the dissolved oxygen content, thereby influencing aquatic biological activity, promoting certain chemical reactions, or improving water quality. Its main purpose is to reduce dissolved oxygen levels, inhibit the activity of aerobic microorganisms, reduce the oxidation and decomposition of organic matter, and thus purify water, control algae growth, or promote the growth of certain specific organisms.

[0003] Currently, anaerobic ammonia oxidation biological denitrification is a common method for treating low dissolved oxygen water. However, the current operation of anaerobic ammonia oxidation biological denitrification is relatively fixed. The common practice is to introduce the coagulated and settled wastewater and anaerobic ammonia oxidizing bacteria together into the reaction tank, relying on the natural contact and reaction between the water and the anaerobic bacteria to achieve the purpose of dissolution. This process requires a long waiting time and is more suitable for small and medium-sized water volume projects, but it is inefficient for large-scale water treatment. In addition, relying on natural reaction can easily lead to the waste of anaerobic ammonia oxidizing bacteria.

[0004] To address the aforementioned issues, a low-dissolved oxygen integrated water treatment device is provided. Utility Model Content

It relies on the natural contact and reaction between the water and anaerobic bacteria to achieve the purpose of dissolution. This process requires a long waiting time. It is more suitable for small and medium-sized water volume projects, but it is inefficient for large-scale water treatment. Moreover, relying on natural reaction can easily lead to the waste of anaerobic ammonia oxidizing bacteria.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated water treatment device for low dissolved oxygen operation, comprising a support frame, a mixing cylinder horizontally fixed at the lower inner side of the support frame, a hollow rotating shaft rotatably mounted on the inner side of the mixing cylinder along its length, a plurality of stirring paddles on the outer periphery of the hollow rotating shaft, a plurality of gas nozzles arranged on the outer periphery of the hollow rotating shaft along its length, a discharge pipe at the bottom of one side of the mixing cylinder, and a feed inlet and a water inlet respectively provided at one top end of the mixing cylinder; The support frame is respectively provided with a water delivery component connected to the water inlet and a material distribution component connected to the feed inlet; The support frame is also provided with a rotary drive assembly for driving the hollow shaft to rotate axially, and a carbon dioxide gas transmission assembly connected to one end of the hollow shaft.

[0011] As a preferred embodiment of the integrated water treatment device for low dissolved oxygen operation described in this utility model, one end of the hollow rotating shaft passes through the mixing cylinder and the side wall of the support frame, and the hollow rotating shaft and the mixing cylinder are connected by a sealing shaft.

During operation, a diaphragm metering pump guides wastewater into the input end of the mixing cylinder via pipeline, while a screw conveyor uniformly and quantitatively delivers anaerobic ammonia oxidizing bacteria concentrate to the input end of the mixing cylinder. Simultaneously, the rotary drive component drives the hollow rotating shaft and stirring paddle to rotate, actively intervening to rapidly disperse and blend the wastewater and anaerobic bacteria concentrate. Due to the more thorough blending, it is less likely to waste anaerobic ammonia oxidizing bacteria. The mixed solid-liquid mixture is directly discharged into the reaction tank through the discharge pipe. This method not only enables rapid blending of water and anaerobic bacteria concentrate, accelerating the reaction, but also allows for continuous treatment of large volumes of water, significantly improving the reaction efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Figures 1-4 The diagram shown is a complete structural schematic of an integrated water treatment device for low dissolved oxygen operation according to this utility model. Please refer to [link / reference]. Figures 1-4 This embodiment of an integrated water treatment device for low dissolved oxygen operation includes a support frame 100. A mixing cylinder 200 is horizontally fixed to the lower inner side of the support frame 100. A hollow rotating shaft 210 is rotatably mounted on the inner side of the mixing cylinder 200 along its length. The outer periphery of the hollow rotating shaft 210 has several stirring paddles 220, and the outer periphery of the hollow rotating shaft 210 along its length is provided with several gas nozzles 230. A discharge pipe is located at the bottom of one side of the mixing cylinder 200. 240. The top end of the mixing cylinder 200 is provided with a feed inlet 260 and a water inlet 270 respectively; the support frame 100 is provided with a water delivery assembly 300 connected to the water inlet 270 and a uniform material delivery assembly 400 connected to the feed inlet 260 respectively; the support frame 100 is also provided with a rotary drive assembly 500 for driving the hollow rotating shaft 210 to rotate axially and a carbon dioxide gas delivery assembly 600 connected to one end of the hollow rotating shaft 210.

[0023] The connection between the discharge pipe 240 and the mixing cylinder 200 also includes an electromagnetic flow valve 250. The mixing cylinder 200 is arranged at an incline, and the discharge pipe 240 is located at the lower inclined end of the mixing cylinder 200. It can be understood that the slight inclination of the mixing cylinder 200 facilitates a more linear outward discharge of the solid-liquid mixture. In actual use, a level gauge can also be installed above the mixing cylinder 200 to detect the water level in the mixing cylinder 200 during operation, avoiding excessive or insufficient water. The control unit can control the conduction and unit delivery of the electromagnetic flow valve 250 and the diaphragm metering pump 310 based on the feedback of the water level information. The water delivery assembly 300 includes a diaphragm metering pump 310 mounted on the upper end of the support frame 100, a water delivery pipe 320 with one end connected to the output end of the diaphragm metering pump 310 and the other end connected to the inlet 270, and an inlet pipe 330 with one end connected to the input end of the diaphragm metering pump 310 and the other end connected to the sedimentation tank. The uniform feeding assembly 400 includes a screw conveyor 410 embedded in the top of the support frame 100, a storage hopper 420 connected to the top feed end of the screw conveyor 410, and a discharge pipe 430 with one end connected to the bottom output end of the storage hopper 420 and the other end connected to the water inlet 270. Here, the storage hopper 420 is used to store anaerobic ammonia oxidizing bacteria diluent. The lowest point of the lower end of the storage hopper 420 is connected to the feed end of the storage hopper 420. The capacity of the storage hopper 420 can be determined according to actual needs and is not limited thereto. One end of the hollow rotating shaft 210 passes through the mixing cylinder 200 and the side wall of the support frame 100, and the hollow rotating shaft 210 and the mixing cylinder 200 are connected by a sealed shaft. The rotary drive assembly 500 includes a pulley 510 fixed to the outer end of the hollow rotating shaft 210, a pulley 520 rotatably mounted on the outside of the support frame 100, a belt 530 connecting the pulley 510 and the pulley 520, a rotary motor 540 for driving the pulley 520 to rotate axially, and a frame 550 for fixing the rotary motor 540. It can be understood that the speed of the rotary motor 540 is adjustable and can be freely adjusted according to the mixing requirements. Specifically, in this embodiment, by connecting the discharge pipe 240 to the reaction tank, during use, the diaphragm metering pump 310 introduces sewage into the input end of the mixing cylinder 200 through the pipeline, while the screw conveyor 410 also uniformly and quantitatively delivers the anaerobic ammonia oxidizing bacteria diluent to the input end of the mixing cylinder 200. At the same time, the rotary drive assembly 500 drives the hollow rotating shaft 210 and the stirring paddle 220 to rotate, and the sewage and anaerobic bacteria are quickly dispersed and mixed through active intervention. Because the mixing is more thorough, it is less likely to cause waste of anaerobic ammonia oxidizing bacteria. The mixed solid and liquid are directly discharged into the reaction tank through the discharge pipe 240, and the reaction treatment efficiency is further improved.

[0024] Based on the above embodiments, as a further preferred embodiment, the carbon dioxide gas delivery assembly 600 includes a gas delivery pipe 610 with one end connected to the outer end of the hollow rotating shaft 210 and the other end connected to a carbon dioxide gas source, a sealed bearing 620 located at the connection end of the hollow rotating shaft 210 and the gas delivery pipe 610, a plunger-type metering pump 630 disposed on the gas delivery pipe 610, and a fixing bracket 640 for fixing the plunger-type metering pump 630. The plunger metering pump 630 can accurately control the unit delivery volume of gas, while the carbon dioxide gas source can be a carbon dioxide gas storage tank, or a carbon dioxide generator / gas supply machine, etc. In actual use, when the mixing cylinder 200 is stirring the sewage and anaerobic ammonia oxidizing bacteria, carbon dioxide gas can be injected into the hollow rotating shaft 210 at high pressure through the plunger metering pump 630 and the gas delivery pipe 610, and then introduced into the mixed liquid in the mixing cylinder 200 through the gas nozzle 230 in the form of aeration. After the carbon dioxide is mixed with water, it can reduce the oxygen content of the water to a certain extent, further ensuring the anaerobic or anaerobic environment required for sewage reaction, and the reaction treatment effect is better.

[0025] Furthermore, a base 110 is fixed to the bottom of the support frame 100. With the cooperation of the base 110 and the support frame 100, the entire processing mechanism can be fixedly installed, forming a complete device and operating mechanism.

[0026] Furthermore, a controller 700 is also provided on the outside of the support frame 100. It can be understood that the staff can use the controller 700 to preset and control the various operating units of the device, making it more convenient to use.

[0027] In summary, this embodiment of a low-dissolved oxygen integrated water treatment device connects the discharge pipe 240 to the reaction tank. During operation, the diaphragm metering pump 310 introduces wastewater into the input end of the mixing cylinder 200 through pipelines, while the screw conveyor 410 uniformly and quantitatively delivers the anaerobic ammonia oxidizing bacteria diluent to the input end of the mixing cylinder 200. Simultaneously, the rotary drive component 500 drives the hollow rotating shaft 210 and the stirring paddle 220 to rotate, rapidly dispersing and blending the wastewater and anaerobic bacteria through active intervention. Due to the more thorough blending, it is less likely to waste the anaerobic ammonia oxidizing bacteria. The mixed solid and liquid are directly discharged into the reaction tank through the discharge pipe 240. This method not only enables rapid blending of water and anaerobic bacteria, accelerating the reaction, but also allows for continuous treatment of large volumes of water, significantly improving the reaction treatment efficiency.
