[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse.

[0008] In order to facilitate the driving of the rotating shaft to rotate during the process of sewage entering the box, the use of driving source can be reduced and the energy-saving effect can be improved. Furthermore, a rotating chamber is opened in the rotating disk, the water inlet pipe and the drain pipe are respectively connected to the two ends of the rotating chamber, and a plurality of groups of vortex blades are rotatably arranged in the rotating disk, and the plurality of groups of vortex blades are fixedly connected to the rotating shaft.

[0009] In order to facilitate the mixing of the medicine and sewage, and in the process of mixing the medicine and sewage, the effect of driving the vortex blades to rotate can be appropriately increased. Furthermore, a plurality of groups of vortex blades are provided with a diversion chamber, the diversion chamber is connected to the feed pipe, and a through hole is provided on the vortex blade, and the two ends of the through hole are respectively connected to the diversion chamber and the rotation chamber.

[0014] Furthermore, a pull rod is fixedly arranged on the top of the screw rod, and one end of the pull rod away from the screw rod is fixedly connected to the piston plate.

[0015] A method for controlling a control system of an energy-saving sewage treatment device, further comprising the following steps:

[0016] Step 1: The preliminarily purified sewage is passed into the rotating disk through the water inlet pipe, and the reagent and sewage are mixed in the rotating disk;

[0017] Step 2: The mixed sewage is thrown into the box through the distribution plate;

[0018] Step 3: The lifting plate moves up and down to beat and mix the sewage in the box;

[0019] Step 4: The treated sewage is discharged through the discharge section.

[0020] Compared with the prior art, the present invention provides a control system and method for an energy-saving sewage treatment device, which has the following beneficial effects:

[0021] 1. The control system of the energy-saving sewage treatment device can improve the mixing efficiency and reaction quality and the sewage treatment effect by mixing and reacting the sewage and hydrogen peroxide in a rotating disk to make them react initially, and then sprinkle the sewage through the rotating material distribution disk and beat the sewage through the lifting plate;

When the hydrogen peroxide solution enters the rotating chamber through the through hole and the sewage enters the rotating chamber through the water inlet pipe, the rotating vortex blades can mix the sewage with the hydrogen peroxide solution to improve the subsequent mixing efficiency. On the other hand, when the hydrogen peroxide solution reacts with the reducing substances (such as sulfide) in the sewage, a large amount of oxygen and heat will be generated, so that the rotation speed of the vortex blades can be appropriately accelerated, so that the rotating shaft reduces the consumption of the sewage inlet pressure and improves the use effect;

[0023] 3. The control system of the energy-saving sewage treatment device can drive the lifting plate to lift in the box body by rotating the reciprocating screw with the rotating shaft. During the lifting process, the lifting plate can beat the sewage in the box body, and then the sewage passes through the mesh, and the sewage in the box body is properly stirred to make the sewage and the mixed solution evenly mixed. Moreover, when the sewage passes through the mesh, the sewage can be dispersed, which helps to improve the reaction effect of the sewage and hydrogen peroxide;

[0024] 4. The control system of the energy-saving sewage treatment device can slide the pull rod up and down through the connecting rod and the screw during the lifting process of the lifting plate. During the lifting process, the piston plate can be used to pump and exhaust air to improve the aeration effect.

[0025] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention mixes and reacts sewage and hydrogen peroxide in a rotating disk to make them undergo a preliminary reaction, and then sprinkles the sewage through the rotating distribution disk and beats the sewage through the lifting plate, which can improve the mixing efficiency and reaction quality and improve the treatment effect on the sewage.

[0035] Example:

[0036] Reference Figure 1-Figure 6A control system for an energy-saving sewage treatment device includes a box body 1, on which a discharge part is arranged. The discharge part includes a sewage pipe 101 and a discharge pipe 102 fixedly arranged on the box body 1. The water inlet of the discharge pipe 102 is a certain distance away from the bottom of the box body 1. When in use, the treated sewage in the box body 1 can be discharged through the discharge pipe 102, and the sludge and other impurities precipitated in the box body 1 can be discharged through the sewage pipe 101, thereby improving the use effect. Valves are fixedly arranged on the sewage pipe 101 and the discharge pipe 102. It also includes: a rotating disk 2 is fixedly arranged on the inner wall of the box body 1, a water inlet pipe 201 is fixedly arranged at one end of the rotating disk 2, and a storage box 4 for storing medicine is fixedly arranged on the top of the box body 1. The medicine here is preferably hydrogen peroxide. Hydrogen peroxide can oxidize and decompose organic pollutants in sewage, such as phenols, benzene, dyes and other difficult-to-degrade organic matter. It is also an effective disinfectant that can kill bacteria, viruses and other pathogenic microorganisms in water. Compared with chlorine, hydrogen peroxide generates water and oxygen after decomposing in water, and will not produce harmful by-products or residues. In addition, hydrogen peroxide can oxidize and decompose malodorous substances in sewage, such as sulfides, ammonia, etc., thereby eliminating odor and improving the use effect. The rotating disk 2 is provided with a material taking part connected with the material storage box 4, through which the hydrogen peroxide solution in the material storage box 4 can be taken away and then transported to the rotating disk 2. When the sewage enters the box body 1 through the water inlet pipe 201, it can be mixed, diluted and preliminarily reacted with the sewage, thereby improving the uniformity and efficiency of subsequent mixing and improving the use effect; a distribution disk 5 is fixedly provided with a drain pipe 202 at the other end of the rotating disk 2, and the distribution disk 5 is rotatably set at the outlet of the drain pipe 202, and a spiral hole 502 is opened on the distribution disk 5, and the spiral hole 502 is opened with at least two circles. Here, we prefer seven circles, and the spiral directions of two adjacent groups of spiral holes 502 are opposite, and a driving part for driving the distribution disk 5 to rotate is provided in the box body 1. When in use, the sewage after preliminary mixing enters the distribution disk 5, and the driving part is started to rotate the distribution disk 5, so that the sewage can be thrown into the box body 1, which is convenient for the diffusion of sewage and improves the mixing efficiency.

[0037] Reference Figure 2 and Figure 3The material taking part can adopt a metering pump to take materials. Here, we design the material taking part as a spiral feeding rod 302, a rotating shaft 3 is rotatably arranged in the rotating disk 2, a feeding pipe 303 connected with the drain pipe 202 is opened in the rotating shaft 3, a first bracket 307 is fixedly arranged in the feeding pipe 303, one end of the spiral feeding rod 302 is fixedly connected to the first bracket 307, and a discharge pipe 401 is fixedly arranged at the bottom of the storage box 4, and the other end of the spiral feeding rod 302 is extended into the discharge pipe 401. When in use, the spiral feeding rod 302 can be rotated by driving the rotating shaft 3, and then during the rotation of the spiral feeding rod 302, the hydrogen peroxide in the discharge pipe 401 can be transported to the drain pipe 202 under the drive of the spiral feeding rod 302, so as to achieve mixing with sewage and improve the use effect.

[0038] Reference Figure 2 , Figure 3 and Figure 5 A rotating chamber 205 is opened in the rotating disk 2, and the water inlet pipe 201 and the drain pipe 202 are respectively connected to the two ends of the rotating chamber 205, and a plurality of groups of vortex blades 301 are rotatably arranged in the rotating disk 2. The vortex blades 301 are provided with two to ten groups, preferably six groups. The six groups of vortex blades 301 are all fixedly connected to the rotating shaft 3, and are evenly distributed on the outer wall of the rotating shaft 3 in a circular shape. When in use, when the sewage in the water inlet pipe 201 flows into the drain pipe 202, the vortex blades 301 can push the rotating shaft 3 to rotate, and then the rotating shaft 3 rotates with the spiral feeding rod 302 to take the material, which can reduce the use of the driving source and improve the energy saving effect.

[0039] Reference Figure 2 , Figure 3 and Figure 5 , a diversion chamber 304 is provided in each of the six groups of vortex blades 301, and the diversion chamber 304 is connected to the feed pipe 303, and a through hole 305 is provided on the vortex blade 301, and the two ends of the through hole 305 are respectively connected to the diversion chamber 304 and the rotating chamber 205. When in use, the rotating chamber 205 can be divided into a plurality of chambers by the vortex blade 301, and the hydrogen peroxide solution enters the rotating chamber 205 through the through hole 305. When the sewage enters the rotating chamber 205 through the water inlet pipe 201, on the one hand, the rotating vortex blade 301 can mix the sewage and the hydrogen peroxide solution to improve the subsequent mixing efficiency. On the other hand, when the hydrogen peroxide solution reacts with the reducing substances (such as sulfide) in the sewage, a large amount of oxygen and heat will be generated, so that the rotation speed of the vortex blade 301 can be appropriately accelerated, so that the rotating shaft 3 reduces the consumption of the sewage inlet pressure and improves the use effect.

[0040] Reference Figure 2A lifting plate 6 is provided in the box body 1 for lifting and lowering, and a mesh 601 is opened on the lifting plate 6. A reciprocating screw 306 is fixedly provided at the bottom of the rotating shaft 3, and the lifting plate 6 is threadedly connected to the reciprocating screw 306, and a guide rod is fixedly provided in the box body 1. The guide rod can ensure that the lifting plate 6 can be lifted and lowered reliably to avoid deflection. The lifting plate 6 is slidably connected to the guide rod. When in use, the reciprocating screw 306 is rotated by the rotating shaft 3 to drive the lifting plate 6 to be lifted and lowered in the box body 1. During the lifting process, the lifting plate 6 can beat the sewage in the box body 1, and then the sewage passes through the mesh 601, and the sewage in the box body 1 is properly stirred, so that the sewage and the mixed solution are evenly mixed, thereby improving the use effect. A second bracket is fixedly arranged in the mesh 601, a rotating shaft is rotatably arranged on the second bracket, and a rotating blade is fixedly arranged at one end of the rotating shaft. When the sewage passes through the mesh 601, the rotating blade and the rotating shaft can be driven to rotate, which can improve the stirring effect on the one hand, and break up the sewage during the rotation process on the other hand, which helps to improve the mixing effect.

[0041] Reference Figure 2 , Figure 3 and Figure 6 A diffusion cover 203 with a trumpet-shaped structure is fixedly provided at the outlet of the drain pipe 202. By providing the diffusion cover 203, the diffusion range of the sewage into the box body 1 can be expanded, which helps to accelerate the mixing effect. In addition, a limiting ring is fixedly provided at the bottom of the diffusion cover 203. The cross-section of the limiting ring is a T-shaped structure. A connecting groove 501 is provided on the top of the distribution plate 5. The limiting ring is rotatably set in the connecting groove 501. When in use, the diffusion cover 203 is fixedly provided on the drain pipe 202, which facilitates the diffusion of sewage into the box body 1. In addition, a limiting ring is fixedly provided on the diffusion cover 203, and a connecting groove 501 is provided on the distribution plate 5, which can ensure that the distribution plate 5 can rotate reliably and improve the use effect.

[0042] Reference Figure 2 , Figure 3 and Figure 6 The driving part can use a motor to drive the distribution disc 5 to rotate. Here, we design the driving part as follows: a connecting rod 7 is fixedly provided on the lifting plate 6, and a screw 701 is fixedly provided on the top of the connecting rod 7. The screw 701 is threadedly connected to the distribution disc 5. When in use, the lifting plate 6 is used to slide the connecting rod 7 and the screw 701 up and down during the lifting process. The distribution disc 5 can be driven to rotate forward and reverse during the lifting process of the screw 701. During the forward and reverse rotation of the distribution disc 5, the sewage can be fully mixed in the distribution disc 5, which helps to improve the uniformity of subsequent mixing.

[0043] Reference Figure 2-Figure 4A piston chamber 204 is provided in the drain pipe 202, and the bottom of the piston chamber 204 is connected to the diffusion cover 203. A piston plate 703 is slidably arranged in the piston chamber 204. An air inlet pipe 8 connected to the piston chamber 204 is fixedly arranged in the box body 1, and a filter cover is fixedly arranged at the air inlet end of the air inlet pipe 8 to reduce dust from entering the piston chamber 204 and improve the use effect. In addition, an exhaust window is fixedly arranged at the bottom of the box body 1, and an air outlet pipe 801 connected to the piston chamber 204 is fixedly arranged in the lifting plate 6, and a one-way valve is fixedly arranged on the air inlet pipe 8 and the air outlet pipe 801. When in use, a piston chamber 204 is provided in the drain pipe 202, and a piston plate 703 is slidably arranged in the piston chamber 204. By driving the piston plate 703 to slide, air can be drawn from the outside through the air inlet pipe 8, and then transported to the sewage through the air outlet pipe 801, which has a certain aeration effect and improves the reaction between hydrogen peroxide and sewage. A pull rod 702 is fixedly provided on the top of the screw 701, and the end of the pull rod 702 away from the screw 701 is fixedly connected to the piston plate 703. When in use, the lifting plate 6 can slide up and down through the connecting rod 7 and the screw 701 during the lifting process. During the lifting process, the piston plate 703 can be used to evacuate and exhaust air to improve the aeration effect. Moreover, when the piston plate 703 rises, the material distribution plate 5 is in a forward and reverse switching state, which is close to a stopped state. The pressure in the diffusion cover 203 increases. In order to reduce the impact on the inlet pressure of the water inlet pipe 201, it is made as stable as possible. , part of the sewage in the drain pipe 202 will enter the bottom of the piston chamber 204, increasing the storage space in the drain pipe 202, which helps to appropriately reduce the internal pressure, and then when the piston plate 703 slides downward, the sewage at the bottom of the piston chamber 204 is pressed into the diffusion cover 203. At this time, the pressure in the diffusion cover 203 increases again. Since the distribution plate 5 has rotated, the pressure at this time can accelerate the outflow of sewage from the spiral hole 502 of the distribution plate 5, and under the action of the spiral hole 502, the rotation effect of the distribution plate 5 can be accelerated, thereby reducing the resistance of the screw 701 and the rotating shaft 3, and improving the use effect.

[0044] A method for controlling a control system of an energy-saving sewage treatment device, further comprising the following steps:

[0045] Step 1: The preliminarily purified sewage is introduced into the rotating disk 2 through the water inlet pipe 201, and the reagent and sewage are mixed in the rotating disk 2;

[0046] After the initial purification is to remove the particulate matter in the sewage, when in use, the sewage well water inlet pipe 201 after the initial purification is transported to the box body 1 through the pump body, and the sewage and hydrogen peroxide are initially mixed and reacted in the rotating disk 2, which is convenient for subsequent re-mixing and improves the use effect;

[0047] Step 2: The mixed sewage is sprinkled into the box 1 through the distribution plate 5;

[0048] When in use, the sewage can be thrown into the box 1 by the rotating material distribution plate 5, which speeds up the mixing speed of the sewage and improves the use effect.

[0049] Step 3: The lifting plate 6 moves up and down to beat and mix the sewage in the box 1;

[0050] When the sewage enters the rotating disk 2 and drives the rotating shaft 3 to rotate, the reciprocating screw 306 can drive the lifting plate 6 to move up and down, and then beat the sewage in the box 1. When the sewage passes through the mesh 601, it is dispersed, which helps to improve the reaction efficiency with hydrogen peroxide;

[0051] Step 4: The treated sewage is discharged through the discharge part;

[0052] After the sewage treatment is completed, the treated sewage in the box body 1 can be discharged through the discharge pipe 102, and the impurities such as sludge precipitated in the box body 1 can be discharged through the sewage pipe 101, thereby improving the use effect.
