Description

Technical Field

[0001] This utility model relates to the field of phosphorus removal equipment for fishery wastewater, specifically to a phosphorus removal device with an electrochemical device for use in fishery wastewater. Background Technology

[0002] Fishery wastewater is highly polluted organic wastewater generated during aquaculture and fishery processing. Its main components are uneaten feed, feces, processing debris, and chemical drugs. Direct discharge of this wastewater can lead to serious environmental problems such as eutrophication, hypoxia, and disease transmission. Therefore, it must be effectively treated before discharge to achieve green and sustainable development of fisheries.

[0003] Existing fishery wastewater needs to be treated by filtration, biological denitrification, biological phosphorus removal, and chemical phosphorus removal. When chemically removing phosphorus from fishery wastewater, phosphorus removal equipment is required.

[0004] Existing phosphorus removal equipment cannot accelerate the filtration speed of insoluble precipitates when chemically removing phosphorus from aquatic wastewater. It cannot prevent insoluble precipitates from hindering the rapid and complete passage of filtrate, nor can it prevent insoluble precipitates from accumulating on the filter plates. It is also inconvenient to collect insoluble precipitates and cannot maintain the filtration efficiency and quality of the filter plates.

[0015] Furthermore, the output device is an output pipe with a solenoid valve, and the drainage device is a drainage pipe with a solenoid valve.

[0016] Furthermore, the processing tank and the sedimentation tank are connected by a connecting frame.

[0017] Furthermore, the live connection device includes an annular base disposed on the inner bottom surface of the treatment tank and located below the hemispherical filter plate. The top surface of the annular base is provided with an annular movable groove. The bottom surface of the hemispherical filter plate and located within the annular movable groove is provided with an annular movable plate. An elastic element is provided between the bottom surface of the annular movable plate and the annular base and located within the annular movable groove.

[0018] Furthermore, the elastic element includes several springs, which are equidistantly arranged around the annular base. The springs are located between the bottom end face of the annular movable plate and the annular base and within the annular movable groove.

[0021] Furthermore, an electrochemical device is provided on the inner wall of the precipitation cylinder, which is a set of electrodes disposed on the inner wall of the precipitation cylinder.

[0022] Therefore, this utility model provides the following effects and / or advantages:

[0023] 1) The wastewater storage and conveying device is used to store treated fishery wastewater, which includes treatments such as filtration, biological denitrification, biological phosphorus removal, and pH adjustment. The wastewater storage and conveying device is used to periodically convey fishery wastewater to the sedimentation tank at a predetermined flow rate. The chemical storage and conveying device is used to store metal salt coagulant, which is one of aluminum sulfate, ferric chloride, ferrous sulfate, and polyaluminum chloride. The chemical storage and conveying device is used to convey a predetermined amount of metal salt coagulant to the sedimentation tank during the conveying of fishery wastewater from the wastewater storage and conveying device to the sedimentation tank.

[0024] The sedimentation tank is used to receive fishery wastewater from the wastewater storage and transportation device and metal salt coagulant from the chemical storage and transportation device. The sedimentation tank is used to allow the fishery wastewater to react with the metal salt coagulant to form insoluble precipitates. The output device is used to periodically transport the mixture in the sedimentation tank to the dispersion plate at a predetermined flow rate after all the fishery wastewater in the sedimentation tank has reacted with the metal salt coagulant to form insoluble precipitates. The dispersion plate is used to receive the mixture from the output device and to disperse the mixture when receiving it, so that the mixture is dispersed and flows toward the hemispherical filter plate.

[0025] The hemispherical filter plate is used to filter the mixture dispersed by the dispersion plate. The dispersed mixture moves downward along the surface of the hemispherical filter plate. The live-connected device is used to drive the hemispherical filter plate to move continuously while the output device is conveying the mixture into the sedimentation tank of the dispersion plate. This allows the filtrate in the mixture to quickly enter the interior of the hemispherical filter plate and fall off the hemispherical filter plate into the bottom surface of the processing tank while the mixture moves downward along the surface of the hemispherical filter plate. This ensures that the mixture is filtered quickly and completely without hindering the subsequent entry of filtrate into the hemispherical filter plate, thus ensuring the filtration efficiency and quality of the hemispherical filter plate. Furthermore, this device allows all insoluble precipitates in the mixture to move downward along the surface of the hemispherical filter plate to the bottom surface of the processing tank. The insoluble precipitates in the mixture do not accumulate on the hemispherical filter plate but are concentrated at the bottom surface of the processing tank, facilitating the collection of insoluble precipitates and maintaining the filtration efficiency and quality of the hemispherical filter plate.

[0026] The draining device is used to discharge the filtrate that has entered the interior of the hemispherical filter plate and fallen into the bottom surface of the treatment tank. The cleaning door is used to open when driven to clean the insoluble precipitate inside the bottom surface of the treatment tank and outside the hemispherical filter plate out of the treatment tank.

[0027] In summary, chemical phosphorus removal of aquatic wastewater can accelerate the filtration rate of insoluble precipitates, prevent insoluble precipitates from hindering the rapid and complete passage of filtrate, prevent insoluble precipitates from accumulating on the filter plates, facilitate the collection of insoluble precipitates, and maintain the filtration efficiency and quality of the filter plates.

[0028] 2) The quick-reaction anti-sinking frame is driven to rotate continuously before the output device conveys the mixture in the sedimentation cylinder to the dispersion plate, so as to allow the fishery wastewater and metal salt coagulant to react quickly to generate insoluble precipitates, thereby preventing the insoluble precipitates from settling on the bottom surface of the sedimentation cylinder; the quick-reaction anti-sinking drive device is used to drive the quick-reaction anti-sinking frame to move.

[0029] 3) The electrochemical device is used to be continuously energized before the output device delivers the mixture in the precipitation cylinder to the dispersion plate, so as to make the insoluble precipitate already generated in the precipitation cylinder larger and denser, so as to sterilize and decolorize the mixture in the precipitation cylinder.

[0048] The active device is used to drive the hemispherical filter plate 5 to move continuously during the process of the output device 4 conveying the mixture in the sedimentation cylinder 3 to the dispersion plate 7. This allows the filtrate in the mixture to quickly enter the interior of the hemispherical filter plate 5 and fall off the hemispherical filter plate 5 into the bottom surface of the processing tank 2 while the mixture moves downward along the surface of the hemispherical filter plate 5. This ensures that the mixture is filtered quickly and completely without hindering the subsequent filtrate from entering the hemispherical filter plate 5, thus ensuring the filtration efficiency and quality of the hemispherical filter plate 5. During the process of the mixture moving downward along the surface of the hemispherical filter plate 5, all insoluble precipitates in the mixture move along the surface of the hemispherical filter plate 5 to the bottom surface of the processing tank 2. The insoluble precipitates in the mixture do not accumulate on the hemispherical filter plate 5 and can be concentrated on the bottom surface of the processing tank 2, which facilitates the collection of insoluble precipitates and maintains the filtration efficiency and quality of the hemispherical filter plate 5.
