Description

Technical Field

[0001] This utility model relates to the technical field of water treatment and purification devices, specifically a water treatment and purification device. Background Technology

[0002] Biofilm water treatment devices are a clever fusion of modern membrane separation technology and biotechnology. They use membrane modules to replace traditional secondary sedimentation tanks, efficiently retaining activated sludge and large molecular organic matter, maintaining a high sludge concentration in the biochemical reaction tank, and significantly improving treatment efficiency. They have significant advantages in the field of wastewater treatment.

[0003] Existing water purification devices often employ biofilm technology to treat wastewater. A biofilm is an active biological layer formed by microorganisms on the surface of a fixed or suspended medium. These microorganisms use organic pollutants in the wastewater as a food source to grow and reproduce. The organic matter in the wastewater is decomposed by the microorganisms on the biofilm. However, prolonged use of biofilm filter plates can easily lead to clogging, resulting in reduced filtration efficiency. The common solution is to replace the biofilm filter plates, which increases treatment costs due to the need for multiple plates and can also affect the sealing performance of the device. To address the shortcomings of existing technologies, this invention provides a water treatment and purification device to solve the aforementioned problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a water treatment and purification device, according to the appendix. Figure 1 As shown, it includes a filter box 1, which serves as the main container of the entire water treatment and purification device, providing space for the installation and operation of other components, containing sewage and collecting treated water;

[0028] A rotating door 2 is provided on one side of the filter box 1. A second control handle 21 is fixedly connected to the rotating door 2. The rotating door 2 facilitates the inspection, cleaning and replacement of the biofilm filter plate 3 inside the filter box 1.

[0029] According to the appendix Figure 2 As shown, further, the biofilm filter plate 3 is installed inside the filter box 1. When sewage flows through the biofilm filter plate 3, the microorganisms in the biofilm can decompose the organic matter in the sewage and remove some pollutants, thereby achieving sewage purification.

[0030] The guiding unit 5 includes a guide inclined filter plate 51 fixedly connected inside the filter box 1. The function of the guide inclined filter plate 51 is to evenly guide the sewage entering the filter box 1 onto the biofilm filter plate 3, so that the sewage can be more evenly distributed on the surface of the biofilm filter plate 3, thereby improving the filtration effect. The guiding unit 5 is used to evenly guide the sewage onto the biofilm filter plate 3 for filtration.

[0031] The adjustment unit 6 includes a rotating circular plate 61 rotatably connected to the outer wall of the filter box 1. A horizontal connecting member 62 is fixedly connected to the rotating circular plate 61, and a vertical connecting member 63 is fixedly connected to the horizontal connecting member 62. A first nozzle 621 and a second nozzle 631 are respectively provided on the horizontal connecting member 62 and the vertical connecting member 63. The adjustment unit 6 is used to adjust the first nozzle 621 and the second nozzle 631.

[0032] The guide unit 5 also includes:

[0033] The fixing rod 52 is fixedly connected between the guide inclined filter plate 51 and the inner wall of the filter box 1;

[0034] The protective plate 53 is fixedly connected to the guide inclined filter plate 51.

[0035] A water supply unit 4 is provided between the filter box 1 and the vertical connector 63. The water supply unit 4 is used to provide high-pressure water flow. The water supply unit 4 includes:

[0036] High-pressure water pump 41 is installed on the side wall of filter box 1;

[0037] The connecting pipe 42 is attached to the high-pressure water pump 41 at one end and to the vertical connector 63 at the other end.

[0038] A connecting plate 31 is fixedly connected to the side wall of the biofilm filter plate 3. The connecting plate 31 plays a role in strengthening the structural stability of the biofilm filter plate 3, and at the same time facilitates the installation and fixation of the biofilm filter plate 3 in the filter box 1.

[0039] The bottom of the filter box 1 is provided with a water outlet pipe 11, which is used to discharge the purified water out of the filter box 1. A solenoid valve 111 is provided on the water outlet pipe 11. By controlling the opening and closing of the solenoid valve 111, the flow rate and discharge time of the water in the water outlet pipe 11 can be precisely controlled to achieve automatic control.

[0040] A first control handle 64 is fixedly connected to the rotating circular plate 61.

[0041] Working principle: Wastewater is introduced into the filter box 1 through an external pipe. The wastewater first comes into contact with the guide inclined filter plate 51 in the guide unit 5. Under the action of the guide inclined filter plate 51, the wastewater flows evenly to the biofilm filter plate 3. When the wastewater flows through the biofilm filter plate 3, the biofilm on the surface of the biofilm filter plate 3 decomposes and adsorbs the organic matter in the wastewater, removing some pollutants and achieving preliminary purification. The water filtered by the biofilm filter plate 3 collects at the bottom of the filter box 1. When it is necessary to discharge the treated water, the solenoid valve 111 on the outlet pipe 11 is opened through the control system, and the purified water is discharged from the outlet pipe 11.

[0042] After the device has been running for a period of time, some impurities and blockages will adhere to the surface of the biofilm filter plate 3, affecting the filtration effect. First, close the solenoid valve 111 on the outlet pipe 11. Then, the operator holds the first control handle 64 and rotates the rotating disc 61, which drives the horizontal connecting piece 62 and the vertical connecting piece 63 to rotate, adjusting the first nozzle 621 and the second nozzle 631 to the appropriate position and angle. Then, start the high-pressure water pump 41. The high-pressure water pump 41 pressurizes the water and delivers it to the vertical connecting piece 63 through the connecting pipe 42. Then, high-pressure water jets are sprayed from the first nozzle 621 and the second nozzle 631 to perform a comprehensive backwash of the biofilm filter plate 3, removing impurities and blockages from the surface. After the rinsing is completed, turn off the high-pressure water pump 41, and the device continues to operate normally. On the one hand, it is not necessary to purchase a large number of biofilm filter plates 3, which reduces the treatment cost. On the other hand, it ensures the sealing performance of the device. At the same time, the guide unit 5 facilitates the uniform guidance of sewage to the biofilm filter plate 3 for filtration, preventing local filtration overload.
