Vertical Turbine Agitator

Sewage treatment agitators are an indispensable key equipment in modern sewage treatment systems. Their function is to promote the full mixing of sewage, chemicals and microorganisms through mechanical agitation, thereby improving treatment efficiency. With increasingly stringent environmental protection requirements, the technological innovation and market application of agitators are also showing a diversified trend.

Description

Working principle and core functions
The core function of the sewage treatment agitator is to generate fluid power through the rotation of the impeller, break the solid-liquid stratification in the sewage, prevent sedimentation, and accelerate chemical or biological reactions. According to the principles of fluid mechanics, the agitator works in the following ways:
1. **Hydraulic shear**: The high-speed rotating impeller generates shear force to break up large particles of pollutants for subsequent treatment.
2. **Uniform mixing**: Promote the water flow to form a cycle to ensure uniform distribution of agents (such as flocculants) or oxygen (aerobic treatment process).
3. **Suspension maintenance**: In the activated sludge process, the agitator can keep the microorganisms in full contact with the sewage to avoid sludge deposition.

Main types and technical features
Currently, the sewage treatment agitators on the market can be divided into the following categories, each with its own advantages:
1. **Submersible agitator**
- **Features**: Directly immersed in sewage, compact structure, suitable for deep pools or closed treatment units (such as anaerobic pools).
- **Case**: After a municipal sewage treatment plant adopted a submersible agitator, the sludge mixing efficiency increased by 30% and the energy consumption decreased by 15% (refer to Baidu Encyclopedia data).

2. **Side-entry agitator**
- **Features**: Installed on the pool wall, it achieves large-scale mixing through horizontal push flow, suitable for large oxidation ditches or regulating tanks.
- **Advantages**: Easy maintenance, multiple units can be used in parallel to enhance the effect.

3. **Vertical turbine agitator**
- **Features**: Vertical axis design, strong turbulence generated by turbine blades, suitable for high-concentration sewage or process sections that require rapid response.
- **Innovation**: Some new products use variable frequency motors, which can adjust the speed in real time according to water quality, and have significant energy-saving effects (refer to Baidu Enterprise Service Platform case).

4. **Gas Agitator**
- **Principle**: It drives water flow by releasing compressed air, and has both aeration and stirring functions, suitable for aerobic biological treatment.
