In the field of environmental protection, the extraction tank is playing a more and more important role, and its application scope is constantly expanding, and the prospect is very broad. In terms of wastewater treatment, extraction tanks can be used to treat wastewater containing heavy metal ions, organic pollutants, etc.

For example, for wastewater containing heavy metals, such as copper, nickel, lead and other heavy metal ions, the extraction tank can be used to transfer heavy metal ions from the water phase to the organic phase by adding a suitable extraction agent, so as to achieve the separation and enrichment of heavy metals.

After extraction treatment, the heavy metal content of wastewater can be greatly reduced to meet the discharge standard. At the same time, the enriched heavy metals can be recycled through subsequent treatment such as reverse extraction, which not only reduces environmental pollution, but also realizes the recycling of resources.

The extraction tank is also widely used in the treatment of organic wastewater. For some difficult to degrade organic wastewater, such as phenol wastewater, benzene wastewater, extraction tank can effectively separate organic pollutants from wastewater.

By selecting extractants with high selectivity and extraction ability for target organic pollutants, the transfer of organic pollutants is realized in the extraction tank. The extracted organic phase can be treated by distillation and other methods to recover the extractant and organic pollutants, while the water phase can be further treated to achieve higher discharge standards.

In addition to wastewater treatment, extraction tanks also have potential applications in waste gas purification. Some industrial exhaust gases contain extractable pollutants, which can be absorbed and separated by passing the exhaust gas into an extraction tank containing a specific extractant.

Although the application in this area is still relatively small, with the continuous improvement of environmental protection requirements, the application of extraction tank in the field of waste gas purification is expected to be further expanded.

From the perspective of development, with the increasingly strict environmental protection regulations and the continuous improvement of people's environmental awareness, the treatment requirements for pollutants such as wastewater and waste gas are also getting higher and higher. The extraction tank will be more widely used in the field of environmental protection because of its advantages of simple operation and strong adaptability.

At the same time, with the development of new extractants and the continuous improvement of extraction technology, the performance of the extraction tank will continue to improve, and the treatment efficiency and effect will be further improved, making greater contributions to the cause of environmental protection.
