Description

Technical Field

[0001] This utility model belongs to the technical field of aquaculture wastewater ditch technology, specifically relating to a ditch structure for treating aquaculture wastewater biofilm. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Biofilm methods are mainly used to remove dissolved and colloidal organic pollutants from wastewater.

[0003] In response, Chinese patent application number CN 206767747 U discloses a biofilm backwashing structure for wastewater treatment, comprising a wastewater treatment tank and a biofilm turntable. The top and bottom of the wastewater treatment tank are connected to an inlet pipe and an outlet pipe, respectively. A sewage discharge pipe is connected to one side of the wastewater treatment tank. An air-filled layer and a biofilm turntable are fixedly installed inside the wastewater treatment tank. The air-filled layer is connected to an external air source via an air pipe and is installed on top of the biofilm turntable. The outer side of the biofilm turntable is connected to a turntable frame via a rotating shaft, and a rotary shaft is connected to the bottom of the turntable frame. This utility model has a simple structure and is easy to use. The biofilm turntable can be flipped using a rotating motor, and the biofilm is then cleaned using the inlet pipe. This solves the problem of existing methods where the biofilm is fixed, and the filtered water is backwashed from bottom to top via an outlet pipe and a backwash pump, which is complex, difficult, and costly.

[0004] However, when this structure is used in actual aquaculture wastewater biofilm treatment ditches, due to its own structural limitations, it can usually only completely block the water flow inside the ditch before the aquaculture wastewater biofilm treatment can proceed. After a period of biofilm treatment, blockage occurs inside, which affects the water flow speed inside the ditch, making it impossible to continuously and stably complete the aquaculture wastewater biofilm treatment operation. At the same time, it is impossible to carry out more efficient equipment replacement and use operations, and it cannot meet the daily use needs. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a ditch structure for treating aquaculture wastewater biofilm, in order to solve the problem that existing structures, due to their own structural limitations, can only completely block the water flow inside the ditch before treating the aquaculture wastewater biofilm. After a period of biofilm treatment, blockage occurs inside, which affects the water flow speed inside the ditch, making it impossible to continuously and stably complete the aquaculture wastewater biofilm treatment operation. At the same time, it is impossible to carry out more efficient equipment replacement and use operations, and it cannot meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ditch structure for treating aquaculture wastewater biofilm, including a conveying ditch, assembly components are provided on both sides of the conveying ditch, and a treatment component is offset on one side of the inner wall of the assembly components;

[0007] The assembly component includes a first ditch and a second ditch, with the first ditch movably connected to one side of the conveying ditch and the second ditch movably connected to the other side of the conveying ditch;

[0008] The processing assembly includes a first processing frame and a second processing frame. The first processing frame is fixedly connected to one side of the inner wall of the first ditch, and the second processing frame is fixedly connected to one side of the inner wall of the second ditch. The first processing frame and the second processing frame are designed to be staggered in position, and the first processing frame and the second processing frame have the same structure but opposite directions.

[0009] Preferably, the first processing rack is internally connected to a pull-out rack, and the bottom of the pull-out rack is provided with a biofilm body.

[0010] Preferably, a sealing ring is provided between the first processing frame and the pull-out frame, and a discharge chute is provided on one side of the first processing frame.

[0011] Preferably, a discharge rack is fixedly connected to one side of the first processing rack, and the discharge rack is provided with flow-dividing baffles evenly arranged inside, with guide plates arranged between the flow-dividing baffles.

[0012] Preferably, a plug-in plate is fixedly connected to one side of the conveying ditch, and a plug-in groove is provided on the other side of the conveying ditch.

[0013] Preferably, sealing rings are provided on both sides of the conveying ditch.

[0014] Preferably, the conveying ditch, the first ditch, and the second ditch are adapted to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This ditch structure for treating aquaculture wastewater using biofilm, through its set of conveying ditch, first ditch, second ditch, first treatment frame, second treatment frame, pull-out frame, biofilm body, connecting plates, connecting grooves, and sealing rings, ensures that the water flow inside the ditch remains at a high speed during the aquaculture wastewater biofilm treatment operation. In actual use, operators can first connect multiple sets of conveying ditch, first ditch, and second ditch by connecting the connecting plates and connecting grooves on both sides, and with the sealing rings providing a tight seal, ensure the final connection and stability of the ditch for water delivery. Then, the aquaculture wastewater is circulated. During the flow, the wastewater can flow back and forth between the first and second ditches, while the first and second treatment racks act as barriers. In conjunction with the pull-out racks and biofilm bodies inside the first and second treatment racks, the wastewater is continuously filtered. On the other side of the first and second treatment racks inside the first and second ditches, the water flow remains efficient. Multiple sets of first and second treatment racks work together to complete the continuous and efficient biofilm treatment of the aquaculture wastewater, demonstrating the practicality of the equipment design.

[0017] 2. The ditch structure for treating aquaculture wastewater using biofilm further improves the overall performance of the equipment by incorporating a first treatment frame, a second treatment frame, a pull-out frame, the biofilm body, a sealing ring, a discharge trough, a discharge rack, a diversion baffle, and a guide ramp. During daily use, operators can pull out multiple sets of pull-out frames from the top of the first or second treatment frame. After the biofilm body inside the pull-out frame has been used for a period of time, it can be pulled out from the top of the pull-out frame, and a new pull-out frame with a fresh biofilm body can be inserted back into the first or second treatment frame. At this time, the sealing ring is installed and connected. Simultaneously, the discharge rack can process the aquaculture wastewater at the discharge trough on one side of the first and second treatment frames, thus accelerating the flow of the wastewater in the conveying ditch, the first ditch, and the second ditch, demonstrating the comprehensiveness of the equipment design.

[0025] This utility model provides a ditch structure for treating aquaculture wastewater using a biofilm, as shown in the figure. It includes a conveying ditch 1, with assembly components on both sides of the conveying ditch 1. A treatment component is offset from one side of the inner wall of each assembly component. A connector plate 13 is fixedly connected to one side of the conveying ditch 1, and a connector groove 14 is provided on the other side. Sealing rings 15 are provided on both sides of the conveying ditch 1. The conveying ditch 1, the first ditch 2, and the second ditch 3 are compatible. Multiple sets of conveying ditches 1, the first ditch 2, and the second ditch 3 are connected by the connector plates 13 and the connector grooves 14 on both sides. With the sealing fit of the sealing rings 15, the sealing stability of the final water transport connection of the ditch is ensured, and then the flow operation of the aquaculture wastewater is carried out.

[0026] The assembly includes a first channel 2 and a second channel 3. The first channel 2 is movably connected to one side of the conveying channel 1, and the second channel 3 is movably connected to the other side of the conveying channel 1. The processing assembly includes a first processing frame 4 and a second processing frame 5. The first processing frame 4 is fixedly connected to one side of the inner wall of the first channel 2, and the second processing frame 5 is fixedly connected to one side of the inner wall of the second channel 3. The first processing frame 4 and the second processing frame 5 are designed with staggered positions. The first processing frame 4 and the second processing frame 5 have the same structure but opposite orientations. A pull-out frame 6 is movably connected inside the first processing frame 4, and a biofilm body 7 is provided at the bottom of the pull-out frame 6. A sealing ring 8 is provided between the first processing frame 4 and the pull-out frame 6. A discharge trough 9 is provided on one side of the first processing frame 4.
