Description

Technical Field

[0001] This utility model belongs to the field of biological contact oxidation tank technology, specifically relating to a carbon and oxygen conveying device for a biological contact oxidation tank in wastewater treatment. Background Technology

[0002] A biological contact oxidation tank is an oxidation tank consisting of a tank body, packing material, water distribution device, and aeration device. The packing material is set in the aeration tank to serve as a carrier for the biofilm. The wastewater to be treated flows through the packing material at a certain flow rate after being oxygenated, and comes into contact with the biofilm. The biofilm and the suspended activated sludge work together to purify the wastewater.

[0003] In response, Chinese patent application number CN 106554071 B discloses a biological contact oxidation tank, comprising a tank body, a biofilm packing material, an aeration device, a wastewater inlet, and a wastewater outlet channel. The tank body features a flow guide channel, which is separated from the biofilm packing material by a first flow guide wall. The aeration device and the wastewater inlet are located at the bottom of the flow guide channel, and a horizontal flow layer is located at the top of the flow guide channel, connecting the flow guide channel and the biofilm packing material. The tank body is equipped with a stirring device, and several stirring blades are fixed on the drive shaft of the stirring device and extend into the flow guide channel. This solution provides a biological contact oxidation tank that not only achieves good bubble diffusion, enabling uniform oxygen distribution within the tank, but also has low equipment modification costs and a low failure rate.

[0004] However, when this structure is used for the slow-release carbon source and oxygen transport in the biological contact oxidation tank, due to its own structural limitations, it cannot achieve a more uniform aeration and mixing operation of the slow-release carbon source and oxygen in the tank. It can only rely on the upward flow of air from the bottom, which easily leads to poor biological contact oxidation. At the same time, the equipment cannot perform more efficient internal exhaust operation for biological contact oxidation, which 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 invention is to provide a carbon and oxygen conveying device for a biological contact oxidation tank in wastewater treatment. This addresses the limitations of existing structures when conveying slow-release carbon and oxygen in biological contact oxidation tanks. Due to structural constraints, these devices cannot achieve more uniform aeration and mixing of the slow-release carbon and oxygen within the tank. They rely solely on upward airflow from the bottom, which can lead to poor biological contact oxidation. Furthermore, the devices cannot perform more efficient internal venting operations for biological contact oxidation, thus failing to meet daily usage requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a carbon and oxygen conveying device for a biological contact oxidation tank in sewage treatment, comprising a tank body, wherein a tank trough is provided inside the tank body, conveying components are provided at the upper and lower ends of the tank body, and an agitation component is provided at the top of the tank body;

[0007] The conveying assembly includes an air outlet top frame and an air inlet bottom frame. The top of the pool body is fixedly connected to the air outlet top frame, and the bottom of the pool body is fixedly connected to the air inlet bottom frame. Air distribution corner seats are provided at the four corners between the air outlet top frame and the air inlet bottom frame.

[0008] The agitation assembly includes a top cover, which is movably connected to the top of the pool body, and a drive motor is provided on the surface of the top cover.

[0009] Preferably, the bottom end of the top cover is equipped with an agitator roller via a drive motor, and the agitator roller is adapted to the center of the pool.

[0010] Preferably, a sealing ring is provided at the bottom edge of the top cover, and the air outlet top frame and the top cover are sealed together by the sealing ring.

[0011] Preferably, the inner wall of the uniform air angle seat is provided with aeration hole grooves.

[0012] Preferably, an air inlet seat is provided on the back of the air outlet top frame, and an air inlet pipe is fixedly connected to the bottom end of the air inlet seat.

[0013] Preferably, the inner wall of the air outlet top frame is provided with an air outlet mesh groove, and an air outlet seat is fixedly connected to the front of the air outlet top frame.

[0014] Preferably, the pool body and the top cover are adapted to each other.

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

[0016] 1. This carbon and oxygen conveying device for the biological contact oxidation tank in wastewater treatment, through the tank body, tank trough, air outlet top frame, air inlet bottom frame, air distribution corner seats, aeration hole slots, air inlet seats, and air inlet pipes, enables the equipment to perform a better, more uniform, and stable continuous delivery of slow-release carbon source and oxygen within the biological contact oxidation tank. In actual use, the operator first connects the pipes for conveying slow-release carbon source and oxygen to the air inlet seats inside the air outlet top frame. After the slow-release carbon source and oxygen are introduced into the air inlet seats, they can be conveyed downwards along the air inlet pipe at the bottom, then enter the air inlet bottom frame, and then be evenly conveyed from the air inlet bottom frame to the four corner air distribution corner seats. Finally, they are evenly output through the aeration hole slots on the inner wall of the air distribution corner seats, thus achieving uniform aeration operation in the four corners of the tank trough, thereby improving the contact effect of the biological contact oxidation tank and demonstrating the practicality of the equipment design.

[0017] 2. This wastewater treatment biological contact oxidation tank carbon and oxygen conveying device, through the tank body, tank trough, top cover, drive motor, stirring roller, sealing ring, air outlet mesh trough, and air outlet seat, further improves the overall performance of the equipment. During daily use, the operator can attach the entire top cover to the air outlet top frame at the top of the tank body. At this time, the air outlet top frame and the top cover can be sealed and positioned together by the sealing ring. Then, the drive motor on the surface of the top cover can be started to drive the stirring roller to stir inside the tank trough. At the same time, the air outlet pipe can be connected to the air outlet seat, which is connected to the air outlet mesh trough on the inner wall of the air outlet top frame, so that the gas discharged by the stirring roller can be evenly absorbed, demonstrating the comprehensiveness of the equipment design.

The unit is equipped with an air inlet seat 11, and an air inlet pipe 12 is fixedly connected to the bottom end of the air inlet seat 11. An air outlet mesh groove 13 is provided on the inner wall of the air outlet top frame 3. An air outlet seat 14 is fixedly connected to the front of the air outlet top frame 3. The pool body 1 and the top cover 6 are compatible. When the slow-release carbon source and oxygen are introduced into the air inlet seat 11 inside the air outlet top frame 3, they can be transported downward along the air inlet pipe 12 at the bottom end, and then enter the air inlet bottom frame 4. From the air inlet bottom frame 4, they are evenly transported to the four corner air distribution seats 5.

[0026] The agitation assembly includes a top cover 6, which is movably connected to the top of the tank body 1.
