Push flow mixing aerator integrated aeration equipment for sewage biochemical tank push flow aeration

Product basic parameters and core structure

1. Equipment model: The entire series of aerators includes multiple specifications such as LF-7.5, LF-11, LF-22, and LF-37. The main engine power ranges from 7.5kW to 37kW, and the supporting fan power ranges from 3kW to 7.6kW. It can be selected and matched according to the tank volume and sewage load.

2. Core structure: The whole machine consists of a drive motor, a matching fan, an intake duct, impeller components, a support frame, and a gas supply system. The frame structure is stable and easy to install and disassemble.

3. Impeller specifications: The diameter range of the impeller is 380mm~580mm. The large-diameter impeller enhances the water pushing ability and forms a long-distance directional water flow.

4. Working water depth: The LF-37 model is suitable for water depths ranging from 3m to 20m, and can adapt to deep water conditions ranging from 4m to 20m. The deep water environment still maintains stable flow and aeration effects.

5. Air intake capacity: The single unit has an air intake of 330m ³/h~702m ³/h, providing sufficient gas supply to ensure the supply of oxygen to microorganisms in the pool.

6. Pushing distance: The effective pushing range of a single unit is 10~70m, which can drive large-scale water circulation and eliminate dead corners of water flow in the pool.

7. Operating principle: The equipment is equipped with a fan to transport air, and the airflow and water are fully mixed in the impeller area. Under the rotating thrust of the impeller, the water gas mixture is directed into the water, and on the one hand, a large number of microbubbles diffuse to increase the dissolved oxygen in the water; On the other hand, relying on strong thrust to drive the continuous flow of water, achieving a circulation effect that promotes the circulation, rapidly increasing DO values, and degrading organic pollutants and ammonia nitrogen.

8. Material configuration: The frame can be treated with carbon steel anti-corrosion, and the impeller can be made of stainless steel material. For highly corrosive chemical wastewater scenarios, special anti-corrosion customization is supported.

9. Control mode: It can be combined with an electric control cabinet to achieve manual and automatic control, support linkage of multiple devices, can be connected to the factory DCS automatic control system, and is suitable for unmanned sewage stations.

10. Factory inspection: Before leaving the factory, each device shall undergo a complete no-load test run, air tightness test, vibration and noise detection, and be accompanied by a product certificate, installation drawings, and technical documentation.

Applicable industries and equipment operating conditions of the product

1. Municipal sewage treatment project: The AO process tank, oxidation ditch, and push flow aerobic tank of the urban sewage plant provide continuous oxygen supply and promote directional circulation of the water body to prevent sludge settling, ensure microbial activity, and efficiently degrade COD and ammonia nitrogen.

3. Water ecological restoration project: black and odorous river treatment, landscape water purification, artificial lake water quality improvement, breaking water stratification and improving water ecological environment through continuous aeration and flow pushing.

4. Upgrading and renovating old sewage treatment plants: For projects where the dissolved oxygen in the original biochemical tank is insufficient and sludge deposition is severe, a push flow mixing aerator can be installed without the need for large-scale civil engineering modifications to improve the system's treatment capacity.

5. Treatment of large rectangular tank bodies: Targeting the characteristics of long-distance directional flow in long corridor aeration tanks, the equipment perfectly adapts to the flow state requirements of the corridor. Compared with ordinary submersible aerators, the directional control effect of water flow is better.

There are significant differences in positioning between push flow mixing aerators and ordinary submersible mixing aerators. Ordinary submersible agitator aerators focus on global turbulent mixing, while push flow agitator aerators specialize in directional long-distance push flow and are more suitable for gallery and long strip aeration tanks. They have outstanding advantages in maintaining directional water flow and simulating the flow state of push flow biochemical processes.

Frequently Asked Questions (FAQ)

Q1: What is the working principle of the push flow mixing aerator?

A: The supporting fan transports compressed air, which mixes with water at the impeller position. With the rotation of the impeller, it generates strong thrust and directs the water vapor mixture into the water. While continuously increasing dissolved oxygen through aeration, a long-distance directional water flow is formed to promote the circulation of water in the tank, prevent sedimentation of activated sludge, degrade organic matter and ammonia nitrogen in the water, and build a stable biochemical treatment environment.

Q2: What is the difference between a push flow mixing aerator and a submersible mixing aerator?

A: The submersible agitator aerator focuses on turbulent mixing throughout the entire tank and is suitable for square and circular tank bodies; The push flow agitator aerator is mainly used for directional long-distance push flow, which is more suitable for long corridors and push flow AO biochemical tanks. It can form a continuous flow state, perfectly matching the push flow process, and has better performance in long tank projects.

Q3: Does equipment installation require civil engineering renovation of the pool body?

A: Under normal working conditions, there is no need for large-scale civil engineering renovation. It is fixed and installed using brackets. Old sewage tanks can be directly retrofitted, with a short construction period and quick improvement of the problems of insufficient dissolved oxygen and sludge deposition in the tank.

Q4: Can it be equipped with an automated control system?

A: Support. It can be paired with a fully automatic electrical control cabinet to achieve equipment timing start and stop, and can also be connected to the DCS system in the factory area to link start and stop according to dissolved oxygen probe signals, achieving intelligent unmanned operation.
