With the rapid development of China's industrialization process, a large number of industrial wastewater has been produced, which has brought serious challenges to environmental protection. As the main technical method of wastewater treatment and resource utilization, solvent extraction is not only a key means to solve circular ecological pollution, but also an important way to help realize carbon neutrality.

In industrial production, wastewater with phenol concentration higher than 1000 mg/L is called high concentration phenol wastewater, and wastewater with less than 1000 mg/L is called low concentration phenol wastewater. In the treatment of phenol-containing wastewater, on the one hand, it is necessary to reduce the content of phenol-containing wastewater, so as to meet the discharge standards and reduce the pollution to the environment. On the other hand, we should try to recover the valuable substances in the wastewater, so that it can turn waste into treasure and achieve green governance.

At present, the commonly used industrial treatment methods of phenol-containing wastewater are biochemical, adsorption and solvent extraction. Among them, the centrifugal solvent extraction method has become a popular method in industry because of its high extraction efficiency, wide application of wastewater, low input and use cost, and small footprint. As the key equipment of this method, the combined extraction centrifugal extractor is particularly outstanding in the treatment of phenolic wastewater with its high efficiency centrifugal separation technology.

The combined extraction centrifugal extractor achieves efficient substance separation through its high-speed rotation and powerful centrifugal force, making the extraction process more rapid and accurate. The separation factor is large and the extraction rate is high, which ensures the efficient separation and purification of phenols in wastewater.

The low power consumption design and high solvent utilization of the combined extractor make the equipment not only efficient, but also more environmentally friendly. Through multistage countercurrent centrifugal extraction, the phenol content of wastewater can be generally reduced to 100 ppm, which greatly reduces the pollution to the environment.

The combined extraction centrifugal extractor can establish the phase balance in a short time to ensure the efficient and stable operation of the entire extraction process. Through multistage countercurrent operation, the separation efficiency and processing capacity are further improved.

In addition to its excellent performance in the treatment of phenol-containing wastewater, the combined extraction centrifugal extractor also shows a wide range of application potential in the treatment of other industrial wastewater:

The combined extraction centrifugal extractor can efficiently separate the heavy metal ions in the wastewater, reduce its concentration, and ensure the wastewater discharge standards.

In the process of chemical production, it is often necessary to recover organic solvents in wastewater. Combined extraction centrifugal extractor can recover organic solvent efficiently and reduce resource waste through high efficiency centrifugal separation technology.

The application of combined extraction centrifugal extractor not only improves the efficiency and effect of industrial wastewater treatment, but also promotes the green development of the entire environmental protection wastewater treatment industry. Its characteristics of high efficiency, energy saving and environmental protection make it an ideal choice for industrial wastewater treatment and provide strong support for the sustainable development of the industry.
