Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a denitrification filtration mechanism for treating domestic wastewater. Background Technology

[0002] Domestic sewage refers to various types of wastewater generated in people's daily lives. The organic matter in domestic sewage mainly comes from food scraps, human excrement, and detergents. These organic substances consume dissolved oxygen in the water, and under the decomposition of microorganisms, they can lead to oxygen deficiency in the water, affecting the survival of aquatic organisms.

[0003] For the treatment of domestic sewage, chemical reactions are required. The denitrification filtration system used for domestic sewage treatment is a combination of equipment used to treat domestic sewage, specifically to remove nitrates from the sewage and filter and purify the sewage. It mainly works based on the principles of physical filtration and chemical reduction reaction.

[0004] Existing technologies for denitrification filtration in domestic sewage treatment utilize substances with reducing properties to chemically react with nitrates in sewage, converting the nitrogen in nitrates into harmless gases such as nitrogen gas, thereby reducing the nitrogen content in sewage. However, when sewage enters the first treatment zone of the filtration tank, the location of the water injection pipe and the water flow velocity cause uneven distribution of sewage within the first treatment zone. Existing technologies have improved the design of the water injection pipe by adopting a multi-point distributed water injection method to solve the problem of uneven distribution of sewage in the first treatment zone. However, when the water flow is low, uneven water flow still occurs, resulting in significant differences in denitrification and filtration effects in different areas, affecting the overall treatment quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a denitrification and filtration mechanism for domestic sewage treatment, aiming to improve the problem in the prior art where uneven water flow leads to significant differences in denitrification and filtration effects in different areas, affecting the overall treatment quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a denitrification filtration mechanism for treating domestic sewage, comprising a filtration tank, an organic body fixedly connected to the top right side of the filtration tank, an organic box fixedly connected to the outer wall of the organic body, a base fixedly connected to the rear end of the organic box, a motor fixedly connected to the top of the base, a rotating shaft fixedly connected to the output end of the motor, a plurality of rotating gears fixedly connected to the outer wall of the rotating shaft, a gate slidably connected to the middle of the organic body, serrated strips fixedly connected to both the front and rear ends of the gate, the rotating gears meshing with the serrated strips, and a delayed feeding mechanism fixedly connected to the top rear side of the filtration tank, the delayed feeding mechanism being used to periodically add reducing agent to the domestic sewage in the treatment area.

[0007] As a further description of the above technical solution:

[0008] The delayed feeding mechanism includes a housing, which is fixedly connected to the top rear side of the filter tank. A second motor is fixedly connected to the left end of the housing, and a second rotating shaft is fixedly connected to the output end of the second motor. A second rotating gear is fixedly connected to the other end of the second rotating shaft.

A fourth rotating shaft is rotatably connected to the bottom of the housing, and a fourth rotating gear is fixedly connected to the top end of the fourth rotating shaft. The toggle bar meshes with the fourth rotating gear. A toggle block is fixedly connected to the outer wall of the fourth rotating shaft. A storage box is fixedly connected to the right end of the housing, and a baffle is rotatably connected to the front end of the storage box.

[0009] As a further description of the above technical solution:

[0010] A water passage trough is provided at the left end of the filter pool, and multiple railings are fixedly connected inside the water passage trough.

[0011] As a further description of the above technical solution:

[0012] Multiple filter screens are fixedly connected to the right end of the filter pool, and multiple filter grooves are opened on the outer side of the multiple filter screens.

[0013] As a further description of the above technical solution:

[0014] Multiple hinges are fixedly connected to the top right side of the housing, and a mechanical door is fixedly connected to the right end of each hinge.

[0015] As a further description of the above technical solution:

[0016] A support column is fixedly connected to the top of the mechanical door, and a handle is fixedly connected to the top of the support column.

[0017] As a further description of the above technical solution:

[0018] Multiple fixed platforms are provided at the right end of the filtration tank, and sewage pipes are fixedly connected to the upper end of the fixed platforms.

[0019] As a further description of the above technical solution:

[0020] The rear end of the sewage pipe is fixedly connected to a connecting plate, and the outer wall of the connecting plate is threaded with multiple screws.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the output end of motor one drives shaft one to rotate, and the rotating gear one on shaft one drives the sawtooth strip, causing the gate to move up and down. This realizes the control of the gate height to adjust the water flow, and solves the problem that uneven water flow leads to large differences in denitrification and filtration effects in different areas, affecting the overall treatment quality.

[0023] 2. In this utility model, the output end of motor two rotates, causing gear two to drive gear three via a connecting belt, which in turn drives gear four via a toggle bar, thus opening the baffle and enabling the periodic addition of reducing agent to the domestic sewage in the treatment area. This solves the problems of wasted time and low efficiency caused by adding reducing agent to domestic sewage multiple times. Attached Figure Description
