Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, specifically a water ecological restoration system based on watershed water management. Background Technology

[0002] With the increasing development and utilization of environmental resources, large amounts of pollutants containing nitrogen and phosphorus nutrients are continuously discharged into lakes, reservoirs and rivers, causing the nutrient load on water bodies to increase continuously. On the other hand, in order to increase crop yields, the application of chemical fertilizers and livestock manure in farmland has been increasing year by year. After being washed away and infiltrated by rainwater, more and more nutrients enter the water bodies. Due to these human factors, the problems of water pollution and eutrophication are becoming increasingly serious.

[0003] The effective management of eutrophic water bodies has become a critical environmental issue that urgently needs to be addressed. In eutrophic water bodies, blue-green algae proliferate in large quantities, deteriorating water quality, losing its aesthetic value, worsening the quality of water supply sources, harming the physical and mental health of residents in lake areas, damaging the lake's ecosystem, reducing the stability and diversity of aquatic organisms, causing the disappearance of some precious fish species, and significantly reducing the economic benefits of aquaculture.

[0004] According to CN112723544B, a water ecological restoration system based on watershed water management includes a wastewater purification filter and a flood storage and irrigation wetland. The wastewater purification filter is equipped with an aerobic treatment chamber, an anoxic treatment chamber, and a baffled anaerobic chamber, achieving a spatial sequence of reciprocating cycles between anoxic, anaerobic, and aerobic processes. However, this device directly places the wastewater purification filter at the river discharge outlet, allowing wastewater to be discharged into the filter for purification. While this existing device allows direct discharge of river wastewater for treatment, the surface of the discharged wastewater often contains large amounts of leaves and other large debris. Direct discharge into the wastewater purification filter can easily cause blockages at the filter inlet due to these large particles, slowing down the discharge process, severely impacting wastewater treatment efficiency, reducing the filter's lifespan, and hindering ecological restoration. Therefore, we propose a water ecological restoration system based on watershed water management. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention includes a filtration mechanism. The first filter screen on the filtration mechanism enables primary filtration of sewage, filtering large-volume contaminants from river sewage onto the surface of the first filter screen. When the drive motor drives the rotating shaft to rotate, the cleaning brush outside the rotating shaft can scrub the surface of the first filter screen, preventing it from becoming clogged. At the same time, the rotation of the rotating shaft drives two pulverizing blades outside the cleaning brush to rotate, quickly pulverizing large-volume contaminants on the surface of the first filter screen, thus facilitating the discharge of contaminants and ensuring the long-term filtration effect of the filtration mechanism.

[0017] 2. This invention enables secondary filtration of river sewage by setting two secondary filtration boxes outside the primary filtration box. The two secondary filtration boxes can be used alternately, which facilitates the cleaning of dirt on the second filter screen inside the secondary filtration box.

[0018] 3. This invention can remove large-volume pollutants from river sewage through a filtration mechanism, reducing the burden of the water treatment tank on river sewage treatment. The sewage entering the anaerobic chamber does not contain large-volume pollutants, allowing the sludge filling material in the anaerobic chamber to better degrade the organic matter in the sewage, greatly improving water treatment efficiency.

[0019] 4. In this invention, the water treated in the anaerobic chamber flows into the aerobic chamber through a connecting pipe. At the same time, the fan blows air through the air outlet, and the water in the connecting pipe splashes against the air outlet through the water outlet. The air outlet blows air towards the water. The impact of the two causes the water to splash and come into contact with the air to a greater extent, which greatly increases the oxygen content in the water compared with traditional devices. The treated water is then adsorbed by the activated carbon layer to remove particles in the water, resulting in better water treatment effect. Attached Figure Description

[0024] 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 only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-3 The present invention provides a technical solution: a water ecological restoration system based on watershed water conservancy allocation, including a filtration mechanism 1 and a water treatment tank 2. The filtration mechanism 1 and the water treatment tank 2 are connected. A filtration mechanism 1 is set before water treatment. The filtration mechanism 1 can remove large-volume pollutants mixed in river sewage, so that the filtered water can be further treated by the water treatment tank 2, which greatly improves the water treatment efficiency.

[0026] The filtration mechanism 1 includes a primary filter box 3, with an inlet pipe 4 connected to the top of the primary filter box 3. A sludge storage tank 5 is provided at the bottom of the primary filter box 3, and a rotating shaft 6 is rotatably connected to the inner wall of the sludge storage tank 5 in the horizontal direction via a bearing. A spiral blade 7 is provided on the outer side of the rotating shaft 6. A drive motor 8 is fixedly installed on the side wall of the primary filter box 3. The drive motor 8 is controlled by the control system of the device to rotate the rotating shaft 6. The spiral blade 7 on the outside of the rotating shaft 6 can transport out the sludge.

[0027] The output shaft of the drive motor 8 extends into the primary filter box 3 and is fixedly connected to the rotating shaft 6. A first filter screen 9 is installed at the bottom of the sludge storage tank 5. Water entering the primary filter box 3 is filtered through the first filter screen 9, allowing large-volume dirt to be filtered off its surface. Cleaning brushes 10 are fixedly mounted at equal intervals on the outer side of the rotating shaft 6 above the first filter screen 9, with the ends of the cleaning brushes 10 contacting the first filter screen 9. Crusher blades 11 are symmetrically fixedly connected to the outer side of the rotating shaft 6 outside the cleaning brushes 10. The primary filter box 3 is located away from the drive motor 8. A drain port 12 is provided at the bottom of the side, and an installation cover 13 is fixedly installed at the end of the drain port 12. The ends of the rotating shaft 6 and the spiral blade 7 are both located inside the drain port 12. During the rotation of the rotating shaft 6, the cleaning brush 10 installed outside the rotating shaft 6 brushes the surface of the first filter screen 9, avoiding the clogging of the first filter screen 9 and ensuring the filtration effect. While the cleaning brush 10 brushes the surface of the first filter screen 9, the pulverizing blade 11 outside the rotating shaft 6 can pulverize larger dirt. The pulverized dirt is transported and discharged under the action of 7, ensuring the normal operation of the filter.

[0028] It should be noted that, in use, river sewage is discharged into the primary filter box 3 through the inlet pipe 4. The sewage is filtered through the first filter screen 9, causing the sludge to accumulate in the storage tank 5. When a large amount of sludge accumulates in the storage tank 5, the control system can control the drive motor 8 to rotate the rotating shaft 6. Under the action of the spiral blades 7, the sludge is transported to the discharge port 12. Opening the mounting cover 13 allows the sludge to be discharged. During the rotation of the rotating shaft 6, the cleaning brush 10 installed on the outside of the rotating shaft 6 brushes the surface of the first filter screen 9, preventing clogging of the first filter screen 9 and ensuring the filtration effect. While the surface of the first filter screen 9 is being brushed, larger impurities are pulverized by the external shredder 11 of the rotating shaft 6. The pulverized impurities are then transported and discharged under the action of 7, ensuring the normal operation of the filter. The control valve 16 on one branch pipe 15 is closed, and the water pump 22 operates to draw water from the primary filter box 3 into the secondary filter box 17. The water undergoes secondary filtration through the second filter screen 18 inside the secondary filter box 17, removing most of the impurities from the wastewater. When a large amount of impurities accumulates on the second filter screen 18 in one of the secondary filter boxes 17, the control valve 16 on the currently flowing branch pipe 15 is closed, and the control valve 16 on the other branch pipe is opened. A control valve 16 on a branch pipe 15 causes another secondary filter box 17 to filter, while the connecting cover 19 on the secondary filter box 17 with more accumulated dirt is opened. During the removal of the connecting cover 19, the second filter screen 18 is removed, facilitating cleaning of the second filter screen 18. Water entering the bottom of the anaerobic chamber 23 is discharged through the drain outlets 28 on multiple installation branch pipes 27. The installation branch pipes 27 are evenly installed at the bottom of the inner wall of the anaerobic chamber 23, so that the water is evenly distributed and discharged inside the anaerobic chamber 23. The dirt in the water is filtered through the grid layer 30 and the filter brick layer 31, and then enters the packing layer 32, which is filled with... The sludge degrades the organic matter in the wastewater through the packing layer 32. As the water level rises, the water flows into the aerobic chamber 24 through the connecting pipe 34. At the same time, the outlet 35 blows air through the air outlet 38, and the water in the connecting pipe 34 splashes onto the air outlet 38 through the outlet 35. The air outlet blows air towards the water, greatly increasing the oxygen content in the water. The treated water passes through the activated carbon layer 41 to adsorb the particles in the water. Then, the water enters the purification chamber 25 through the overflow outlet 43. Ozone is added to the water through the ozone pipe 45. Then, it passes through the filter element 46 for adsorption again. Finally, the treated water flows into the buffer chamber 47 and is discharged through the drain pipe 48.

[0029] The water treatment tank 2 is equipped with an anaerobic chamber 23, an aerobic chamber 24, and a purification chamber 25. The anaerobic chamber 23 is located at one end of the primary filtration tank 3 inside the water treatment tank 2, and the aerobic chamber 24 is located outside the anaerobic chamber 23 inside the water treatment tank 2. River sewage is treated separately through the anaerobic chamber 23 and the aerobic chamber 24, which can effectively remove harmful microorganisms from the river sewage. The purification chamber 25 is located at the end of the filtration mechanism 1 away from the anaerobic chamber 23, and the water can be purified through the purification chamber 25.

[0030] The bottom of the primary filter box 3 is connected to a water pipe 14, and the end of the water pipe 14 forms two branch pipes 15. A control valve 16 is installed on the outside of the branch pipes 15, and the ends of the two branch pipes 15 are connected to a secondary filter box 17. A connecting cover 19 is installed on the top of the secondary filter box 17. A second filter screen 18 is slidably arranged inside the secondary filter box 17. A connecting rod 20 is fixedly connected between the connecting cover 19 and the second filter screen 18. The connection point between the branch pipes 15 and the secondary filter box 17 is located above the second filter screen 18. A connecting pipe 21 is connected to the bottom of the second filter screen 18. By setting two secondary filter boxes 17 outside the primary filter box 3, secondary filtration of river sewage can be achieved. The two secondary filter boxes 17 can be used alternately for filtration, which facilitates the cleaning of dirt on the second filter screen 18 inside the secondary filter box 17.

[0031] A water pump 22 is fixedly installed at the bottom of the water treatment tank 2. The ends of the two connecting pipes 21 are connected to the inlet of the water pump 22. An installation pipe 26 is installed at the outlet of the water pump 22, and the end of the installation pipe 26 is wrapped around the bottom of the inner wall of the anaerobic chamber 23. An installation branch pipe 27 is installed at equal intervals on a section of the installation pipe 26 inside the anaerobic chamber 23, and a drain outlet 28 is opened at equal intervals on the outer side of the installation branch pipe 27. The port of the drain outlet 28 is set facing directly upward. The water pump 22 can pump the filtered water into the anaerobic chamber 23. The even arrangement of multiple installation branch pipes 27 in the anaerobic chamber 23 can make the water inside the anaerobic chamber 23 evenly distributed, ensuring the removal of anaerobic organisms from the sewage.

A section of the connecting pipe 34 inside the aerobic chamber 24 is provided with outlets 35 at equal intervals. The pollutants in the water are filtered through the grid layer 30 and the filter brick layer 31, and then enter the packing layer 32. The packing layer 32 is filled with sludge, so that the packing layer 32 degrades the organic matter in the sewage.

The water treated in the anaerobic chamber 23 flows into the aerobic chamber 24 through the connecting pipe 34. At the same time, the fan 36 blows air through the air outlet 38, and the water in the connecting pipe 34 splashes onto the air outlet 38 through the water outlet 35. The air outlet 38 blows air towards the water. The impact of the two causes the water to splash and come into contact with the air to a greater extent, which greatly increases the oxygen content in the water compared with traditional devices. The treated water is then adsorbed by the activated carbon layer 41 to remove particles in the water, resulting in better water treatment effect.

[0034] The connecting pipe 34 and the ventilation pipe 37 are both arranged in a U-shape inside the aerobic chamber 24. The air outlet 38 is located directly below the water outlet 35. The water treated in the anaerobic chamber 23 flows into the aerobic chamber 24 through the connecting pipe 34. At the same time, the fan 36 blows air through the air outlet 38. The water in the connecting pipe 34 splashes onto the air outlet 38 through the water outlet 35, and the air outlet 38 blows air towards the water. The impact of the two causes the water to splash and come into contact with the air to a greater extent, which greatly increases the oxygen content in the water compared with traditional devices.
