For chemical organic wastewater, a common treatment method is to use solvent extraction to extract and separate the organic matter in the organic wastewater to reduce the COD in the wastewater, so as to meet the subsequent standards for entering the biochemical section.

Solvent extraction is a commonly used method of wastewater treatment. The main method is to select suitable extractants, select centrifugal extractor equipment, inject the extractant and wastewater into the centrifugal extractor, and quickly mix and separate the two through centrifugal force. , The organic matter in the wastewater is removed and recycled, so as to achieve the purpose of reducing COD.

The reason why the processing equipment chooses the centrifugal extractor is mainly because the centrifugal extractor is a new and efficient liquid-liquid extraction equipment, which can extract organic matter with a larger processing capacity, and is more energy-saving and higher in extraction efficiency.

When a centrifugal extractor is used for treatment, first determine the wastewater system, select the appropriate extractant according to the specific components of the wastewater, determine the comparison and temperature through experiments, and after the preliminary work is ready, inject the wastewater and the extractant into the centrifugal extraction according to a certain ratio The machine enters the annulus-type mixing zone formed between the rotating drum and the shell. With the rotation of the rotating drum, the two-phase is quickly mixed and dispersed through the turbine disc and the impeller, and the two-phase solution is fully transferred. Under the action of centrifugal force, the mixed liquid undergoes two-phase separation, and the clarified two-phase liquid finally enters the collection chamber through the respective weir plates and is led out of the machine by the guide tube to complete the two-phase separation process.


Compared with traditional extraction equipment, centrifugal extraction machine has its unique performance advantages:

1. The structure of the centrifugal extraction machine is simple and stable. It adopts the structure of a single fulcrum suspended above, which prolongs the service life of the equipment and saves equipment maintenance costs.

2. This series of equipment has larger processing capacity, more energy saving, and high mixing and extraction efficiency, which can be applied to systems that are easy to emulsify.

3. The equipment can be made of perfluorinated polymer materials, which can resist the corrosion of strong acid (hydrochloric acid, mixed acid, etc.).

4. The equipment has a high degree of automation and can fully adapt to intermittent and continuous operation.
