[0031] Embodiment:

[0032] Referring to Figures 1-8 , an environment-friendly multifunctional wastewater treatment device for municipal engineering, including a treatment tank 1. A treatment trough 2 is provided inside the treatment tank 1. A water inlet pipe 21 is fixedly connected to the top of the treatment tank 1. The water inlet pipe 21 is inclined and communicates with the top inner cavity of the treatment trough 2. The other end of the water inlet pipe 21 is communicated with the wastewater source. The water-powered impeller 3 is driven to rotate by the potential energy and impact force of the water flow. A water outlet pipe 22 is fixedly connected to the bottom of the treatment tank 1. The water outlet pipe 22 communicates with the bottom inner cavity of the treatment trough 2. It also includes: a water-powered impeller 3 rotatably connected inside the treatment trough 2. A slag filtering part for filtering impurities in the wastewater is arranged in each impeller of the water-powered impeller 3. Among them, a sewage discharge box 4 is fixedly connected to the side wall of the treatment tank 1. A slag pumping part for discharging the impurities filtered by the slag filtering part is arranged inside the sewage discharge box 4; an aeration chamber 5 is opened inside the treatment tank 1. An air charging part for aeration and purification into the treatment trough 2 is arranged inside the aeration chamber 5.

[0033] Referring to Figures 3-5 , among which, the slag filtering part includes a water resistance plate 6. Slag filtering grooves 61 are opened on the inner concave arc side walls of the water-powered impeller 3. The water resistance plate 6 is rotatably connected to the top of the input end side wall of the slag filtering groove 61. A slag filtering net 62 is fixedly connected to the inner wall of the output end of the slag filtering groove 61. A first spring 63 is fixedly connected between the water resistance plate 6 and the slag filtering net 62. The rotating shaft of the water-powered impeller 3 is hollow. A slag discharging groove 64 is opened between each slag filtering groove 61 and the inner cavity of the rotating shaft of the water-powered impeller 3. A slag discharging plate 641 is rotatably connected to the slag discharging groove 64 through a torsion spring rotating shaft. The torsion spring rotating shaft adopts existing mature technology, and the specific model is KST289A, that is, when the slag discharging plate 641 is stressed, it will rotate, and when it is not stressed, the slag discharging plate 641 will reset under the action of the torsion spring, so as to realize the adaptive opening and closing of the slag discharging groove 64; a one-way baffle 642 is fixedly connected to the slag discharging groove 64, and the inner cavity of the rotating shaft of the water-powered impeller 3 communicates with the inner cavity of the sewage discharge box 4. A limiting sliding groove 611 is opened on the side wall of the slag filtering groove 61. The water resistance plate 6 rotates around its rotating shaft and along the inner wall of the limiting sliding groove 611. The limiting sliding groove 611 is used to guide and position the sliding track of the water resistance plate 6, so that it can only slide inside the inner cavity of the limiting sliding groove 611, improving the rationality of the design;

[0034] Through the above-mentioned structure, wastewater is introduced into the treatment tank 2 from the water inlet pipe 21. Under the action of the potential energy and impact of the wastewater, the hydraulic impeller 3 will be driven to rotate. When the wastewater enters the cavity between the hydraulic impeller 3 and the treatment tank 2, it will produce a gravity squeezing effect on the concave arc side wall of the hydraulic impeller 3, causing the water resistance plate 6 to rotate along its rotation axis toward the inside of the filter residue tank 61, thereby opening the input end of the filter residue tank 61 and allowing the wastewater to enter the filter residue tank 61. At this time, the water flow portion of the wastewater will pass through the filter residue net 62 at the bottom of the filter residue tank 61, while the impurities will be trapped in the filter residue tank 61. Moreover, as the hydraulic impeller 3 rotates, it will switch to the other cavity formed by the hydraulic impeller 3 and the treatment tank 2. After the filter residue tank 61 has collected the impurities, the first spring 63 inside it will cause the water resistance plate 6 to rotate and reset, thereby sealing the impurities in the filter residue tank 61, achieving filtration and collection of impurities in the wastewater, and completing the preliminary treatment of the wastewater.

[0035] Reference Figure 1 、 Figure 7 and Figure 8 , wherein, the slag extraction part includes a slag extraction blade 7, which is rotatably connected to the inner wall of the sewage discharge box 4, and an acceleration shaft 71 is rotatably connected inside the sewage discharge box 4. The rotating shaft of the hydraulic impeller 3 extends through the sewage discharge box 4, and the rotating shaft of the hydraulic impeller 3, the acceleration shaft 71 and the rotating shaft of the slag extraction blade 7 are meshed and connected through an acceleration gear set 72. The bottom of the sewage discharge box 4 is connected to a slag discharge pipe 73. The acceleration gear set 72 is two sets of gears that mesh with each other and of different sizes. The large gear drives the small gear to rotate to achieve acceleration;

[0036] Through the arrangement of the above structure, after a certain amount of impurities are collected in the filter residue trough 61, when the hydraulic impeller 3 rotates to the highest point of the processing tank 2, the gravity of the impurities will press open the slag discharge plate 641 in the slag discharge trough 64, so that the impurities enter the rotating shaft of the hydraulic impeller 3 along the slag discharge trough 64, and when the hydraulic impeller 3 rotates, the cooperation between the acceleration shaft 71 and the acceleration gear set 72 will make the slag extraction blade 7 rotate rapidly, thereby generating a suction effect at the rotating shaft near the hydraulic impeller 3 in the sewage box 4, so that the impurities entering the rotating shaft of the hydraulic impeller 3 are sucked in and fall into the sewage box 4, and finally discharged from the slag discharge pipe 73, thereby discharging impurities in the wastewater and realizing automatic cleaning of impurities, so that the hydraulic impeller 3 can continue to perform wastewater filtering operations without the need to clean impurities regularly, thereby improving the processing efficiency, and only utilizing the potential energy and impact of the wastewater, reducing energy consumption requirements, and being more energy-saving and environmentally friendly.

[0037] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8, wherein, the inflation part includes a piston plate 8. A partition plate 81 is fixedly connected inside the aeration chamber 5. The partition plate 81 divides the inner cavity of the piston plate 8 into an upper cavity and a lower cavity. The piston plate 8 is slidably connected to the inner wall of the upper cavity. A second spring 82 is fixedly connected between the side wall of the piston plate 8 and the inner wall of the upper cavity. The bottom of the lower cavity is communicated with an aeration pipe 83. The other end of the aeration pipe 83 is communicated with the inner cavity of the treatment tank 2. Three groups of aeration pipes 83 are arranged at equal intervals along the axis direction of the water-driven impeller 3. And a check valve is arranged in each aeration pipe 83. A magnetic plate 31 is fixedly connected to the end of each impeller of the water-driven impeller 3. The magnetic plate 31 and the piston plate 8 repel each other magnetically; A secondary drive box 84 is fixedly connected to the side wall of the treatment box 1. The rotating shaft of the water-driven impeller 3 penetrates and extends into the secondary drive box 84 and is fixedly connected with a secondary drive impeller 841. And the secondary drive box 84 is communicated with the inner cavity of the aeration chamber 5 through a guide pipe 842. And a check valve is arranged in the guide pipe 842. An air inlet groove 843 is formed in the side wall of the secondary drive box 84;

[0038] It should be noted that the check valve in the aeration pipe 83 only allows the air flow in the aeration chamber 5 to move into the treatment tank 2; The check valve in the guide pipe 842 only allows the air flow in the secondary drive box 84 to move into the aeration chamber 5;

[0039] Through the setting of the above structure, during the rotation of the water-driven impeller 3, the magnetic plates 31 at different positions will continuously repel the piston plate 8, pushing the piston plate 8 to slide along the upper cavity of the aeration chamber 5, so that the gas in the upper cavity is filled into the wastewater in the treatment tank 2 along the aeration pipe 83, thereby aerating the wastewater, increasing the oxygen content in the wastewater, accelerating the decomposition of organic matter in the wastewater, and improving the treatment effect of the wastewater; And when the magnetic plate 31 and the piston plate 8 are out of the magnetic area, under the rebounding action of the second spring 82, the air flow in the secondary drive box 84 will move into the aeration chamber 5, so as to serve as a gas source supplement to ensure continuous aeration in the follow-up, improving the treatment effect of the wastewater. And when the air flow in the secondary drive box 84 moves continuously, it will push the secondary drive impeller 841 to rotate to a certain extent, thereby assisting the water-driven impeller 3 to better realize the rotation function and ensuring the treatment efficiency.

[0040] Refer to Figure 3 、 Figure 6, wherein, a liquid medicine tank 9 is provided in the treatment tank 1, and a sterilizing and disinfecting agent is contained in the liquid medicine tank 9 for inactivating bacteria, viruses and other microorganisms in the wastewater. A medicine adding tank 91 is provided between the liquid medicine tank 9 and the treatment tank 2. A guiding slide bar 92 is fixedly connected to the bottom of the liquid medicine tank 9, and the guiding end of the guiding slide bar 92 extends into the medicine adding tank 91. A sealing plate 93 is slidably connected to the guiding slide bar 92, and the sealing plate 93 fits and slides along the inner wall of the medicine adding tank 91. A third spring 94 is sleeved on the guiding slide bar 92, and the magnetic plate 31 and the sealing plate 93 repel each other magnetically. The bottom of the liquid medicine tank 9 is semicircularly arranged, and the medicine adding tank 91 communicates with the bottommost part of the semicircle of the liquid medicine tank 9, so that the sterilizing and disinfecting agent in the liquid medicine tank 9 can flow into the medicine adding tank 91 better. A liquid adding hopper 95 is fixedly connected and communicated with the top of the liquid medicine tank 9, so as to facilitate adding the sterilizing and disinfecting agent into the liquid medicine tank 9;

[0041] Through the setting of the above structure, during the rotation of the water-driven impeller 3, the magnetic plates 31 at different positions will continuously repel the sealing plate 93, causing the sealing plate 93 to slide along the guiding slide bar 92 in the medicine adding tank 91, and making the liquid medicine tank 9 communicate with the medicine adding tank 91. At this time, the sterilizing and disinfecting agent in the liquid medicine tank 9 will flow into the treatment tank 2 along the medicine adding tank 91, and along with the rotation of the water-driven impeller 3, it will be mixed with the wastewater, realizing the killing of bacteria, viruses and other microorganisms in the wastewater and improving the treatment effect of the wastewater.

[0042] Refer to Figures 1-8, in the present invention, during use, wastewater is introduced into the treatment tank 2 from the water inlet pipe 21. Under the action of the potential energy and impact force of the wastewater, the water-driven impeller 3 will be pushed to rotate. When the wastewater enters the cavity between the water-driven impeller 3 and the treatment tank 2, a gravitational extrusion effect will be exerted on the concave arc side wall of the water-driven impeller 3, causing the water resistance plate 6 to rotate towards the inside of the slag filtering tank 61 along its axis, thereby opening the input end of the slag filtering tank 61 and allowing the wastewater to enter the slag filtering tank 61. At this time, the flowing water part of the wastewater will pass through the slag filtering net 62 at the bottom of the slag filtering tank 61, while the impurity part will be retained in the slag filtering tank 61. Along with the rotation of the water-driven impeller 3, it will switch to another cavity formed by the water-driven impeller 3 and the treatment tank 2. Under the rebound effect of the first spring 63 inside it, the slag filtering tank 61 that has collected impurities will cause the water resistance plate 6 to rotate back to its original position, thereby sealing the impurities in the slag filtering tank 61, realizing the filtration and collection of impurities in the wastewater, and completing the preliminary treatment of the wastewater; when a certain amount of impurities are collected in the slag filtering tank 61, when the water-driven impeller 3 rotates to the highest position of the treatment tank 2, under the action of the gravity of the impurities, the slag discharge plate 641 in the slag discharge tank 64 will be pressed open, allowing the impurities to flow into the rotating shaft of the water-driven impeller 3 along the slag discharge tank 64. And when the water-driven impeller 3 rotates, by using the cooperation between the acceleration shaft 71 and the acceleration gear set 72, the slag extraction blade 7 will be made to rotate rapidly, thereby generating a suction effect near the rotating shaft of the water-driven impeller 3 in the sewage discharge box 4, causing the impurities that enter the rotating shaft of the water-driven impeller 3 to be sucked over and fall into the sewage discharge box 4, and finally discharged through the slag discharge pipe 73, thereby discharging the impurities in the wastewater, realizing the automatic cleaning of the impurities, enabling the water-driven impeller 3 to continuously carry out the wastewater filtration operation, without the need to regularly clean the impurities, and improving the treatment efficiency;

[0043] Meanwhile, during the rotation of the water-driven impeller 3, the magnetic plates 31 at different positions will continuously repel the sealing plate 93, causing the sealing plate 93 to slide along the guiding slide rod 92 in the chemical dosing tank 91, and making the chemical liquid tank 9 communicate with the chemical dosing tank 91. At this time, the bactericidal and disinfectant in the chemical liquid tank 9 will flow into the treatment tank 2 along the chemical dosing tank 91, and along with the rotation of the water-driven impeller 3, it will be mixed with the wastewater, realizing the disinfection and killing of bacteria, viruses and other microorganisms in the wastewater, improving the treatment effect of the wastewater. When the magnetic plate 31 and the sealing plate 93 are separated from the repelling area, under the rebound effect of the third spring 94, the sealing plate 93 will reset, realizing the blocking of the chemical dosing tank 91, thereby being able to intermittently and quantitatively drip the bactericidal and disinfectant, avoiding the waste of the bactericidal and disinfectant while achieving better treatment efficiency;

[0044] Meanwhile, during the rotation of the water-driven impeller 3, the magnetic plates 31 at different positions will continuously repel the piston plate 8, pushing the piston plate 8 to slide along the upper cavity of the aeration chamber 5, thereby compressing the gas in the upper cavity and causing this part of the compressed gas to enter the aeration pipe 83 along the lower cavity. Under this pressure, the check valve in the aeration pipe 83 is opened, allowing the gas to be filled into the wastewater in the treatment tank 2, thereby aerating the wastewater, increasing the oxygen content in the wastewater, accelerating the decomposition of organic matter in the wastewater, and improving the treatment effect of the wastewater; and when the magnetic plate 31 disengages from the magnetic area of the piston plate 8, under the rebounding action of the second spring 82, the piston plate 8 will be reset, thereby generating a suction force in the aeration chamber 5, thus opening the check valve in the air guide pipe 842 and causing the air flow in the auxiliary box 84 to move into the aeration chamber 5, serving as a gas source supplement to ensure continuous aeration in the follow-up, improving the treatment effect of the wastewater, and when the air flow in the auxiliary box 84 continuously moves, it will push the auxiliary impeller 841 to rotate to a certain extent, thereby assisting the water-driven impeller 3 to better achieve the rotation effect and ensuring the treatment effect.
