Aluminum is an important metal that is widely used in many fields such as construction, transportation and packaging. However, the wastewater discharge of aluminum has caused pollution to the environment, affecting the quality of water and ecological balance. Efficient extraction of aluminum by intelligent combined extraction centrifugal extractor is an important research direction of current environmental governance.

Environmental characteristics of aluminum

Aluminum is present in water mainly in the form of aluminum ions (Al³ +). Its excessive accumulation in water will lead to the deterioration of water quality and affect the growth and reproduction of aquatic organisms. The sediment formed by aluminum in water may also cause turbidity in the water and affect photosynthesis. Therefore, controlling the discharge of aluminum is an important task of water pollution control.

Separation principle of combined extraction centrifugal extractor

The combined extraction centrifugal extractor realizes the efficient separation of aluminum ions through the centrifugal force generated by high-speed rotation. Its main steps include:

1. Feeding stage: The wastewater containing aluminum is injected into the equipment.

2. Centrifugal separation: In the high-speed rotation of the equipment, aluminum ions are forced to settle to the bottom of the equipment because of their larger density.

3. Precipitation collection: The settled aluminum precipitation can be collected through the discharge system.

Optimized extraction conditions

The extraction efficiency of anchored aluminum has the following key parameters to be optimized:

1. Centrifugal speed: The appropriate speed can greatly improve the settling speed of aluminum, the recommended operating range is 4000-8000 rpm.

2. Processing time: Extending the processing time can usually improve the extraction efficiency, and the recommended time is 15-30 minutes.

3. pH adjustment: The separation effect of aluminum is better under acidic conditions (pH 4-6).

Follow-up treatment and reuse of aluminum

The extracted aluminum precipitate can be treated by roasting, recycling and other ways, and the reuse of aluminum can not only reduce environmental pollution, but also provide important raw materials for industrial production.

The application of intelligent combined extraction centrifugal extractor to extract aluminum from wastewater provides an efficient and environmentally friendly solution for environmental governance, promotes the development of water treatment technology, and has a good application prospect.
