Technical Field

[0001] This invention relates to the field of water purification equipment, specifically to a super-strong coagulation magnetic separation water purification equipment. Background Technology

[0002] Currently, magnetic separation water purification technology is widely used in the upgrading and treatment of municipal sewage and black and odorous river water. Existing ordinary magnetic separation integrated water treatment equipment can effectively remove SS, TP, insoluble COD and other substances from sewage, but it does not significantly improve the biodegradability of sewage and has a weak bactericidal effect. Therefore, the improvement and optimization of process-related equipment is a prerequisite for the further development of this technology. Summary of the Invention

[0003] The purpose of this invention is to provide a super-strong coagulation magnetic separation water purification equipment to solve the problems of existing ordinary magnetic separation integrated water treatment equipment not significantly improving the biodegradability of sewage and having a weak bactericidal effect.

A coagulation enhancement tank is disposed between the first reaction tank and the second reaction tank. The first reaction tank and the coagulation enhancement tank, as well as the coagulation enhancement tank and the second reaction tank, are connected through a water outlet. Several parallel waveguides are installed in the coagulation enhancement tank. Each waveguide is connected to a waveguide located outside the coagulation enhancement tank. The waveguide is connected to an electromagnetic wave generator.

[0006] Furthermore, the waveguides are arranged in a crisscross pattern, with one of the two adjacent waveguides having its circular hole positioned vertically while the other is positioned horizontally.

[0007] Furthermore, the outer side of the waveguide is wrapped with a transparent polypropylene tube.

[0008] Furthermore, a flange is installed at one end of the polypropylene pipe, which is connected and fixed to a flange on the outer wall of the concrete strengthening tank, and the other end of the polypropylene pipe is placed on a support installed on the inner wall of the concrete strengthening tank.

[0009] Furthermore, several fixed supports are installed at the bottom of the waveguide, and a polypropylene pipe is fixedly connected to the bottom of the fixed supports.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0021] like Figure 1-4As shown, the present invention provides an ultra-strong coagulation magnetic separation water purification equipment, including a first reaction tank 1 and a second reaction tank 2. A coagulation enhancement tank 3 is arranged between the first reaction tank 1 and the second reaction tank 2. The first reaction tank 1 and the coagulation enhancement tank 3, as well as the coagulation enhancement tank 3 and the second reaction tank 2, are connected through a water outlet. Several parallel waveguides 4 are installed inside the coagulation enhancement tank 3. Each waveguide 4 is connected to a waveguide 5 arranged on the outside of the coagulation enhancement tank 3. The waveguide 5 is connected to an electromagnetic wave generator 6, which is installed on the outer wall of the coagulation enhancement tank 3.

[0022] like Figure 2 As shown, the cross-section of the waveguide 4 is square, and a row of circular holes with a diameter of 1-5cm are provided on the two opposite sides of the waveguide 4. Electromagnetic waves are radiated into the sewage through the circular holes. The waveguides 4 are arranged in a crisscross pattern, with the circular holes of one of the two adjacent waveguides 4 placed vertically and the other horizontally, to ensure uniform propagation of electromagnetic waves.

[0023] The working principle of this super-strong coagulation magnetic separation water purification equipment is as follows: When the equipment is running, coagulant is added to the first reaction tank 1, and then the sewage flows into the coagulation enhancement tank 3 by gravity. The electromagnetic wave generator 6 operates to transmit electromagnetic waves through waveguide 2 5 and waveguide 1 4, and then radiates them into the sewage in the coagulation enhancement tank 3 through the circular hole on waveguide 1 4. Under the combined action of the coagulant and the electromagnetic waves, the pollutants in the sewage generate "electromagnetic oscillations". Long-chain macromolecular polysaccharides break down into short-chain small molecules, and monosaccharides undergo catalytic and physicochemical reactions (such as decolorization due to the destruction of chromogenic groups). This process converts some water-soluble organic pollutants into simple inorganic substances, such as H2O and gases like CO2, H2, and N2, improving the BOD / COD ratio in the water and enhancing the biodegradability of the wastewater. Simultaneously, insoluble (or sparingly soluble) substances and metal ions combine with the coagulant to accelerate the formation of large, highly sedimenting flocculants. Then, magnetic seeds are added to the second reaction tank 2. The specific working principles of the first reaction tank 1 and the second reaction tank 2 are consistent with existing integrated magnetic separation water treatment equipment and will not be detailed here.

[0024] Furthermore, because electromagnetic waves have a strong killing effect on the cells of microorganisms such as bacteria and algae in wastewater, the bactericidal and algae-killing capabilities of this invention are extremely strong. The biological effects (non-thermal effects) of microwaves can cause polar macromolecules in microbial cells to polarize and denature with water, alter cell membrane permeability and ion channels, and act on and destroy secondary bonds that maintain cell structure, ultimately leading to cell death. Therefore, the bactericidal and algae-killing capabilities of this invention are extremely strong.

[0025] The outer side of the waveguide 4 is wrapped with a transparent polypropylene tube 7. One end of the polypropylene tube 7 is fitted with a flange 8, which is connected and fixed to a flange 9 on the outer wall of the concrete strengthening box 3. The other end of the polypropylene tube 7 is placed on a support frame 10 installed on the inner wall of the concrete strengthening box 3. Both ends of the polypropylene tube 7 are fixed to the concrete strengthening box 3 by flange 8 and flange 9, and the other end is supported on the support frame 10 to ensure the stability of the polypropylene tube 7.

[0026] like Figure 5 As shown, several fixing brackets 11 are installed at the bottom of the waveguide 4. The bottom of the fixing brackets 11 is fixedly connected to the polypropylene pipe 7. The fixing brackets 11 are used to fix the waveguide 4.

[0027] The body of the coagulation enhancement tank 3 is made of metal plate. To prevent electromagnetic radiation leakage, the six sides of the coagulation enhancement tank 3 are metal plates, or the other sides except the top are metal plates, and no top is provided. When no top is provided, it must be ensured that the actual water level is higher than the waveguide tube by 420cm when the equipment is running. This can be controlled by a level gauge. If the actual water level does not meet the requirement of being higher than the waveguide tube by 420cm, the electromagnetic wave generator will stop running.

[0028] In summary, the present invention's super-strong coagulation magnetic separation water purification equipment introduces a coagulation enhancement tank between the first and second reaction tanks of ordinary magnetic separation water purification equipment. An electromagnetic wave generator is installed outside the coagulation enhancement tank, and electromagnetic waves enter the tank through waveguides. The specific band of electromagnetic waves is used to enhance the coagulation and flocculation reaction, reduce the chemical bond strength of pollutant molecules, improve the B / C ratio, and enhance the sterilization and disinfection effect.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
