DMF (N, N-dimethylformamide) is an important organic solvent, which is widely used in chemical production process. However, DMF wastewater treatment has always been one of the difficult problems faced by chemical enterprises. The traditional treatment methods often have the problems of high energy consumption and low efficiency. With its unique separation mechanism and high efficiency, the combined extraction centrifugal extractor provides a new solution for DMF wastewater treatment.

Status and challenges of DMF wastewater treatment

The content of organic matter and COD in DMF wastewater are high, and the biochemical treatment is difficult. The traditional treatment methods such as distillation and adsorption have the problems of high energy consumption and low efficiency. In addition, secondary pollution generated during the treatment process also has a serious impact on the environment.

Working principle and advantages of combined extraction centrifugal extractor

The combined extraction centrifugal extractor uses the principle of centrifugal force to realize the rapid mixing and separation of two phases (extractant and wastewater) through a high-speed rotating drum. Its advantages are:

Efficient separation: Under the action of centrifugal force, the DMF in the wastewater can be quickly transferred to the extractant to achieve efficient separation.

Energy saving and environmental protection: Low energy consumption design, reduce energy consumption, while reducing wastewater discharge.

High degree of automation: integrated control system, remote monitoring and automatic adjustment, improve processing efficiency.

Application of combined extraction centrifugal extractor in DMF wastewater treatment

In the treatment of DMF wastewater, the combined extraction centrifugal extractor realizes the efficient and stable treatment process by selecting the appropriate extractant and adjusting the extraction conditions (such as comparison, flow rate, speed, etc.). The experimental results show that the treatment efficiency of the combined extraction centrifugal extractor is increased by nearly 50% and the production cost is reduced by more than 30% compared with the traditional treatment method.

The combined extraction centrifugal extractor has shown remarkable innovation and economy in the treatment of DMF wastewater. In the future, with the continuous progress and optimization of technology, the combined extraction centrifugal extractor is expected to play a greater role in the field of chemical wastewater treatment and contribute to the sustainable development of chemical enterprises.
