Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device and method for ecological protection and river restoration. Background Technology

[0002] River sewage treatment refers to comprehensive management, source control, and ecological restoration of polluted rivers to ultimately purify water quality, restore the environment and ecology, and improve the quality of life. Ecological restoration of sewage requires improvement of water quality in order to protect the river ecosystem.

[0003] Currently, some river sewage treatment equipment is large in size and expensive, so it is often used for the treatment of large rivers. For the ecological treatment of small rivers, workers usually only use tools such as fishing nets to remove plankton and garbage from the river surface. This treatment method is difficult to improve the water quality quickly and does not fundamentally solve the water quality problem. Plankton can also easily regenerate. In addition, when using some river sewage treatment equipment, workers usually use flocculants to aggregate suspended solids or colloidal particles in the water into large clusters in order to improve the clarity of the water source. However, the treatment of flocculent matter in the water usually requires a long sedimentation time, which will affect the overall speed of river treatment. Summary of the Invention

[0004] The purpose of this invention is to provide an ecological protection and river restoration sewage treatment equipment and method. This equipment first filters plankton and other organisms from the sewage, then mixes flocculants with the sewage. Furthermore, the equipment can scrape the bottom of the inner wall of the mesh frame to ensure normal water flow. The pre-treated water can be further treated using solid filler, and the treated water can be directly discharged back into the river, reducing the possibility of re-polluted water due to a prolonged discharge process. This invention solves the problems of some current equipment being costly, unsuitable for small rivers, time-consuming and labor-intensive for plankton and garbage removal, and difficulty in quickly treating flocculent matter in sewage, thus affecting the overall efficiency of river management.

There are two belt pulleys 13, which are connected by belt drive. A moving ring 15 is provided on the surface of the auxiliary moving mechanism 14. A scraping mechanism 16 is installed below the surface of the moving ring 15. A mesh frame 18 is slidably fitted inside the water storage frame 17.

[0039] It should be noted that the quantity of solid filler 24 can be adjusted according to the actual situation to achieve the best treatment effect.

[0040] The support mechanism 2 includes a smooth rod 201, a first support plate 202, a bent rod 203, and a second support plate 204. The smooth rod 201 and the bent rod 203 are both fixedly connected to the top of the base plate 1. The first support plate 202 is fixedly connected to the top of the smooth rod 201, and the second support plate 204 is fixedly connected to the top of the bent rod 203. The surface of the mixing tank 3 is fixedly connected to the inner wall of the first support plate 202 and the bent rod 203. Through the setting of the support mechanism 2, the height of the mixing tank 3 can be supported and fixed for subsequent sewage treatment.

[0041] The water injection assembly 61 includes a support frame 611, a first water pump 612, and a water injection pipe 613. The support frame 611 is fixedly connected to the surface of one side of the mixing tank 3. The first water pump 612 is fixedly connected to the top of the support frame 611. One end of the water injection pipe 613 is connected to the outlet of the first water pump 612, and the other end of the water injection pipe 613 is connected to the mixing tank 3.

[0042] The filter assembly 64 includes a sleeve 641, a filter screen 642, and a baffle plate 643. The inner wall of the sleeve 641 is threadedly connected to the surface of the inlet cylinder 63. The filter screen 642 is fixedly connected to the inner wall of the sleeve 641, and the baffle plate 643 is fixedly connected to the inner wall of the sleeve 641. The baffle plate 643 is disposed inside the filter screen 642. The sealing disc 65 is fixedly connected to the surface of the filter screen 642. In this device, the inlet cylinder 63 is placed in the sewage, and the upper part of the inlet cylinder 63 floats on the water surface. When the operator starts the first water pump 612, the sewage can flow into the filter screen 642 through the baffle plate 643. At this time, the filter screen 642 can filter plankton and other organisms in the sewage. The filtered sewage is injected into the interior of the connecting pipe 62 through the inlet cylinder 63. Based on this, the sewage can be injected into the interior of the mixing tank 3 through the water injection pipe 613 for subsequent treatment.

[0043] The cleaning mechanism 7 includes a disc 71, a rotating shaft 72, a turbine 73, and cleaning rods 74. The disc 71 is rotatably connected to the surface of the sealing disc 65. One end of the rotating shaft 72 rotatably passes through the sealing disc 65 and is fixedly connected to the surface of the disc 71. The turbine 73 is fixedly connected to the other end of the rotating shaft 72. There are several cleaning rods 74, and one end of each cleaning rod 74 is fixedly connected to the surface of the disc 71. The surface of the cleaning rods 74 is in contact with the inner surface of the filter screen 642. When sewage flows into the connecting pipe 62 through the inlet pipe 63, the flow of water in the connecting pipe 62 can drive the turbine 73 to rotate. At this time, the rotating shaft 72 drives the disc 71 to rotate, and the inner surface of the filter screen 642 can be cleaned by the rotation of the cleaning rods 74 to ensure that the sewage can flow normally.

[0044] The barrier plate 643 can reduce the possibility of plankton flowing back into the river. The staff can remove the filter assembly 64 and the cleaning mechanism 7 by periodically rotating the sleeve 641, and then clean them.

[0045] The adjusting mechanism 12 includes a bevel gear disk 121, a vertical shaft 122, a bevel gear 123, and a cam 124. The bevel gear disk 121 is fixedly sleeved on the surface of the mixing rod 10. The vertical shaft 122 rotates through the extension plate 11. The bevel gear 123 is fixedly connected to the top of the vertical shaft 122. The cam 124 is fixedly connected to the bottom of the vertical shaft 122. The bevel gear 123 meshes with the bevel gear disk 121. The surface of the cam 124 contacts the inner surface of the arc plate 20. When the mixing rod 10 rotates, the bevel gear disk 121 rotates accordingly, which can drive the bevel gear 123 to rotate. At this time, the vertical shaft 122 can drive the cam 124 to rotate, so that the arc plate 20 can be squeezed and pushed by the cam 124.

[0046] The auxiliary moving mechanism 14 includes a fixed plate 141, a crossbar 142, a reciprocating screw 143, and a hollow ring 144. There are two fixed plates 141, which are fixedly connected to the underside of the surface of the pulley 13. One end of the crossbar 142 is rotatably connected to the surface of one side of the fixed plate 141, and the other end of the crossbar 142 rotatably passes through the other side of the fixed plate 141. The pulley 13 is fixedly sleeved on the surface of the crossbar 142. The reciprocating screw 143 is fixedly sleeved on the surface of the crossbar 142. The hollow ring 144 is rotatably sleeved on the surface of the crossbar 142. There are two hollow rings 144, which are fixedly connected to the two ends of the reciprocating screw 143. The hollow rings 144 can limit the movable range of the moving ring 15. When the mixing rod 10 rotates, the belt pulley 13 and the belt can drive the crossbar 142 to rotate, and the reciprocating screw 143 can rotate accordingly. The moving ring 15 is threaded onto the surface of the reciprocating screw 143. A thin rod 22 is fixedly connected to the inner wall of the mesh frame 18. The thin rod 22 slides through the moving ring 15. When the reciprocating screw 143 rotates, the position of the moving ring 15 can move.

[0047] The scraping mechanism 16 includes a connecting frame 161, a thin plate 162, and scrapers 163. The connecting frame 161 is fixedly connected to the lower surface of the moving ring 15, and the thin plate 162 is fixedly connected to the bottom of the connecting frame 161. There are several scrapers 163, and each scraper 163 is fixedly connected to the bottom of the thin plate 162. When the moving ring 15 moves, the connecting frame 161 can move and drive the scrapers 163 to move through the thin plate 162. In this way, the scrapers 163 scrape the flocculent material at the bottom of the mesh frame 18, so that the water can flow smoothly into the water storage frame 17 and the water flow rate can be guaranteed, thereby reducing the possibility of water spilling out when the mesh frame 18 shakes due to excessive water accumulation inside the mesh frame 18.

[0048] The reset mechanism 21 includes a reset plate 211, a guide rod 212, and a tension spring 213. The reset plate 211 is fixedly connected to the other side of the top of the mesh frame 18. The guide rod 212 is fixedly connected to the surface of the water storage frame 17 and slides through the reset plate 211. The tension spring 213 is sleeved on the surface of the guide rod 212. The two ends of the tension spring 213 are fixedly connected to the surface of the water storage frame 17 and the inner surface of the reset mechanism 21, respectively. When the cam 124 rotates and presses the arc plate 20, the slide plate 19 can drive the mesh frame 18 to move. Then, under the action of the elastic force of the tension spring 213, the reset plate 211 can drive the mesh frame 18 to move in the opposite direction. Accordingly, the shaking of the mesh frame 18 can accelerate the flow of water. During this process, if the scraping mechanism 16 is obstructed by the mesh frame 18 during movement, it can move in the opposite direction.

[0049] The water conveying mechanism 25 includes a second water pump 251, a pumping pipe 252, and a conveying pipe 253. The second water pump 251 is fixedly connected to the top of the water tank 23. One end of the pumping pipe 252 is connected to the surface of the water storage frame 17, and the other end of the pumping pipe 252 is connected to the water inlet of the second water pump 251. One end of the conveying pipe 253 is connected to the outlet of the pumping pipe 252, and the other end of the conveying pipe 253 is connected to the top of the water tank 23. When the operator starts the second water pump 251, the pre-treated water in the water storage frame 17 can be injected into the interior of the water tank 23 through the pumping pipe 252 and the conveying pipe 253, so that the solid packing material 24 can further treat the water. That is, the microorganisms in the water attach to the solid packing material 24 and form a biofilm, thereby removing dissolved and colloidal organic pollutants in the water through adsorption and biodegradation processes, thereby achieving the purpose of further treating the sewage.

[0050] Working principle: When using this equipment, the operator can first install the equipment on the side of the river through the base plate 1. At this time, the lower half of the water inlet cylinder 63 is placed in the sewage, while the upper half of the water inlet cylinder 63 floats on the surface. Then, the operator starts the first water pump 612, and the sewage can be injected into the mixing tank 3 through the water inlet cylinder 63, the connecting pipe 62, and the water injection pipe 613. During this process, the filter component 64 can filter planktonic organisms in the sewage. At the same time, the cleaning rod 74 rotates to scrape the inner surface of the filter screen 642 so that the water can flow normally.

[0051] During this process, the operator pours flocculant into the mixing tank 3 through the feed pipe 4 and seals the feed pipe 4 with a plug. The operator starts the motor 9, and the mixing rod 10 rotates to mix the sewage and flocculant inside the mixing tank 3, thus facilitating the aggregation of suspended solids or colloidal particles in the water into flocs. Afterward, the operator opens the first valve, and the sewage and flocs flow into the mesh frame 18. The adjusting mechanism 12, in conjunction with the arc plate 20, moves the sliding plate 19. Subsequently, with the cooperation of the reset mechanism 21, the mesh frame 18 shakes to accelerate the water flow. During this process, the mixing rod 10 continues to rotate, which can further process the flocs of the biological material inside the mixing tank 3. The scraper is moved, and the belt pulley 13 and belt work together to drive the crossbar 142 to rotate. The reciprocating screw 143 rotates, which drives the moving ring 15 to move back and forth. The connecting frame 161 drives the scraper 163 to move through the thin plate 162. The flocculent material is retained inside the mesh frame 18, and the water flows into the water storage frame 17. Then, the staff starts the second water pump 251, and the water source inside the water storage frame 17 can be injected into the water tank 23. The solid filler 24 can further remove dissolved and colloidal organic pollutants in the water. Finally, the staff opens the second valve, and the treated sewage can be discharged back into the river through the drain pipe 26. This process is repeated to treat the sewage in the river.
