Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a combined treatment device and treatment process for black and odorous water bodies. Background Art

[0002] With the acceleration of urbanization, urban water environment problems are becoming increasingly prominent. Black and smelly water bodies are usually caused by excessive discharge of organic pollutants. These pollutants consume oxygen in the water, causing hypoxia in the water, which in turn causes the black and smelly phenomenon of the water body. Treating black and smelly water bodies is an important part of urban water environment governance, which helps to improve the city's image and promote the sustainable development of the city.

[0003] In the prior art, in the treatment of black and odorous water bodies (hereinafter referred to as sewage), sewage is introduced into regulating tanks, anaerobic tanks, aerobic tanks, sedimentation tanks and disinfection tanks in sequence; regulating tanks are used to regulate water quality and water volume to ensure the stable operation of subsequent treatment processes; anaerobic tanks remove organic matter through the action of microorganisms under anaerobic conditions, and at the same time help reduce odor; aerobic tanks further degrade organic matter through the metabolic activities of microorganisms under aerobic conditions and promote the nitrification of ammonia nitrogen; sedimentation tanks are used to remove suspended matter in water and improve the clarity of water quality; disinfection tanks are used to add disinfectants (such as chlorine, ozone, etc.) to kill pathogenic microorganisms in water and ensure water safety. These tanks play their respective roles in the joint treatment of black and odorous water bodies. Through scientific and reasonable combination and configuration, they can effectively improve water quality and eliminate black and odorous phenomena.

[0004] However, when sewage is introduced into the regulating tank, it is usually pumped directly from the river into the regulating tank. The sewage contains a large amount of large solid particles, such as mud, packaging bags and other foreign matter. Directly introducing sewage containing such foreign matter into the regulating tank increases the processing burden of each tank and easily causes blockage of pipes and equipment, so further improvement is needed. Summary of the invention

[0006] In the first aspect, the combined treatment device for black and odorous water bodies provided in the present application adopts the following technical solution: A combined treatment device for black and odorous water bodies, comprising a filter kettle, a regulating tank, an anaerobic tank, an aerobic tank, a sedimentation tank and a disinfection tank arranged in sequence, wherein a first partition plate is provided in the filter kettle, and the first partition plate divides the interior of the filter kettle into a first chamber and a second chamber, and the filter kettle is respectively connected with an inlet pipe and a drain pipe, the outlet end of the inlet pipe is connected to the first chamber for introducing sewage, the inlet end of the drain pipe is connected to the second chamber, and the outlet end of the drain pipe is connected to the regulating tank; a second partition plate is provided in the second chamber, and the second partition plate divides the second chamber into two filter areas, each of the filter areas is provided with a filter plate, and a connecting port connected to the first chamber is opened on the top wall of each filter area; a switching component is provided in the first chamber, and the switching component is used to switch the flow direction of sewage so that sewage flows into the corresponding filter area through different connecting ports.

[0007] By adopting the above technical solution and setting up the filter kettle, before the sewage is introduced into the regulating tank, the water inlet pipe leads the sewage to the filter kettle for filtering foreign matter, thereby reducing the possibility of foreign matter such as mud, sand, packaging bags, etc. directly entering the regulating tank, thereby reducing the processing burden of each tank body, and further reducing the possibility of clogging of pipelines and equipment; after the sewage enters the first chamber, it enters the corresponding filter area through one of the connecting ports, and the corresponding filter plate in the filter area can filter the sewage. When the filter plate intercepts a certain amount of foreign matter and needs to be cleaned, the flow direction of the sewage is switched by switching the component, so that the sewage entering the first chamber can flow to the corresponding filter area through another connecting port. At this time, the filter plate that intercepts a certain amount of foreign matter can be cleaned without stopping the machine, so that the overall structure can continue to maintain a working state (that is, it can continue to filter the sewage), thereby improving the working efficiency of the overall structure.

[0008] Optionally, the switching assembly includes a rotating rod, a switching arc plate and a driving member, the rotating rod is rotatably installed in the first chamber, the switching arc plate is arranged on the rotating rod, and the switching arc plate is rotatably installed in the first chamber through the rotating rod; a switching zone is formed between the switching arc plate and the inner wall of the first chamber, and the switching arc plate is rotated to connect the switching zone to the outlet end of the water inlet pipe and to one of the connecting ports. When the switching zone is connected to one of the connecting ports, the switching arc plate isolates the other connecting port; the driving member is arranged on the rotating rod to drive the rotating rod to rotate.

[0009] By adopting the above-mentioned technical scheme, through the setting of the rotating rod, the switching arc plate and the driving member, under normal conditions, the switching arc plate is driven to rotate by the rotating rod, and the rotating angle of the switching arc plate is controlled, so that the switching area is connected to one of the connecting ports and connected to the outlet end of the water inlet pipe at the same time, and the sewage can flow to the corresponding filter area through this connecting port for filtration; when the filter plate corresponding to this filter area intercepts a certain amount of foreign matter, the rotating rod is driven to rotate a certain angle, so that the switching area is connected to the other connecting port and connected to the outlet end of the water inlet pipe at the same time, thereby switching between the two filter areas, which greatly improves the convenience of adjusting the sewage flow direction.

[0013] By adopting the above-mentioned technical solution, through the arrangement of the pushing plate, the connecting rod and the pushing member, the pushing plate and the cover plate are connected into a whole through the connecting rod. When cleaning foreign matter on the filter plate, the pushing plate is driven by the pushing member to move toward the side close to the sewage outlet, and the pushing plate can drive the cover plate to move synchronously to open the sewage outlet. As the pushing plate continues to move, the foreign matter on the filter plate is pushed out from the sewage outlet, thereby greatly improving the convenience of cleaning foreign matter.

[0014] Optionally, the pushing member includes a first gear and a first rack, the first gear is coaxially fixed to the peripheral wall of the rotating rod, the first rack is slidably installed on the first partition plate and connected to the pushing plate, the two ends of the first rack are extended along the moving direction of the pushing plate, and the first rack is meshed with the first gear for transmission.

[0015] By adopting the above-mentioned technical solution, through the setting of the first gear and the first rack, the switching arc plate is driven to rotate through the rotating rod to switch the flow direction of the sewage. The first gear is driven to rotate synchronously during the rotation of the rotating rod, and the first gear and the first rack are engaged and transmitted, thereby driving the push plate to move, thereby improving the convenience of moving the push plate and reducing the manufacturing cost of the overall structure.

[0017] By adopting the above technical solution, through the setting of the docking rod, after one of the filter plates intercepts a certain amount of foreign matter, the switching arc plate is driven to rotate a certain angle through the rotating rod to switch the flow direction of the sewage and make the sewage flow to another filter area; each push plate is connected to the first rack through the docking rod, so that when the rotating rod rotates, it can drive the two push plates to move at the same time; the push plate corresponding to the filter plate intercepting the foreign matter can move toward one side of the sewage outlet to push the foreign matter on the filter plate outward, while the other push plate moves into the filter area, and the cover plate corresponding to this push plate is closed at the corresponding sewage outlet, so that the corresponding filter area can receive sewage; such a setting makes it possible to switch the flow direction of the sewage and clean the foreign matter on the filter plate simultaneously, which greatly improves the working efficiency of the overall structure and improves the convenience of cleaning the foreign matter.

[0018] Optionally, both sides of the filter kettle are provided with collection pools for collecting foreign matter, the two collection pools are arranged corresponding to the two sewage outlets, and the top of the collection pool is open to form an inlet and outlet; the filter kettle is provided with a guide plate at the sewage outlet, and the guide plate has a guide slide, the inlet end of the guide slide is connected to the sewage outlet, and the outlet end of the guide slide is connected to the inlet and outlet of the collection pool.

[0019] By adopting the above-mentioned technical scheme, through the setting of the collection pool and the guide plate, the foreign matter on the filter plate can be pushed outward by the push plate and can slide along the guide slide of the guide plate into the collection pool to collect the foreign matter, thereby facilitating the subsequent transportation of the foreign matter and other work.

When the filter plate moves downward, the linkage drives the free end of the guide plate to swing downward to connect the inlet and outlet of the collection tank.

[0021] By adopting the above technical solution, under normal conditions, the linkage normally rotates the guide plate to a horizontal state. When the filter plate collects a certain amount of foreign matter and causes the filter plate to be blocked, the filter plate is pressed and moves downward. At this time, the linkage drives the free end of the guide plate to swing downward.

During the downward movement, the second rack drives the second gear to rotate through the third gear, so that the guide plate can rotate axially around the rotating shaft, so that the free end of the guide plate is connected to the inlet and outlet of the collection tank. At this time, the staff can switch the flow direction of the sewage; during the switching process of the sewage flow direction, the push bar pushes the foreign matter on the filter plate out of the sewage outlet, and slides it along the guide slide of the guide plate to the collection box, thereby improving the convenience of cleaning foreign matter.

[0024] In the second aspect, the combined treatment process of black and odorous water bodies provided in this application adopts the following technical scheme: A combined treatment process for black and odorous water bodies specifically comprises the following steps: S1, filtration: sewage is led to a filter kettle to filter foreign matter in the sewage; S2, water quality regulation: sewage is led to a regulating tank to regulate water quality; S3, biological reaction: sewage is led to an anaerobic tank and an aerobic tank in sequence to remove organic matter in the sewage; S4, removal of suspended matter: sewage is led to a sedimentation tank to remove suspended matter in the sewage; S5, water quality disinfection: sewage is led to a disinfection tank to kill pathogenic microorganisms in the sewage.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1.

When the filter plate intercepts a certain amount of foreign matter and needs to be cleaned, the flow direction of the sewage is switched by switching the component, so that the sewage entering the first chamber can flow to the corresponding filter area through another connecting port. At this time, the filter plate that intercepts a certain amount of foreign matter can be cleaned without stopping the machine for disposal, so that the overall structure can continue to maintain a working state (that is, it can continue to filter the sewage), thereby improving the working efficiency of the overall structure; 2. Through the arrangement of the push plate, the connecting rod and the push member, the push plate and the cover plate are connected as a whole through the connecting rod. When cleaning the foreign matter on the filter plate, the push member drives the push plate to move toward the side close to the sewage outlet, and the push plate can drive the cover plate to move synchronously to open the sewage outlet. With the continuous movement of the push plate, the foreign matter on the filter plate is pushed out from the sewage outlet, which greatly improves the convenience of cleaning the foreign matter; 3. Through the setting of the linkage, the linkage normally rotates the guide plate to a horizontal state. When the filter plate collects a certain amount of foreign matter and causes the filter plate to be blocked, the filter plate is pressed and moves downward. At this time, the linkage drives the free end of the guide plate to swing downward. The staff can observe the swing of the free end of the guide plate to judge the amount of foreign matter collected on the filter plate, so that the flow direction of the sewage can be switched in time to improve work efficiency.
