In the production process of chemical plants, a lot of chemicals are needed, and the water washing section during product production will produce a large amount of organic wastewater, common ones include phenol-containing wastewater, DMF wastewater, DMAC wastewater, butyric acid wastewater, etc.

Today, we will introduce the chemical plant butyric acid wastewater treatment equipment and treatment process. Zhengzhou Tiei Extraction received a chemical wastewater treatment project from a customer, which mainly extracts butyric acid from chemical organic wastewater. The butyric acid concentration in the wastewater is 5000mg/l. It is hoped that the concentration can be reduced by extraction so that it can be processed in the subsequent biochemical stage.

Solvent extraction is a good method for extracting butyric acid from chemical organic wastewater. Solvent extraction is to select a suitable extractant according to the feed liquid system, mix the extractant with the feed liquid, transfer the organic matter into the extractant and separate it. In the extraction of chemical organic wastewater, the effect of solvent extraction is more significant.

In combination with customer needs, Zhengzhou Tiei Extraction selected CWL-M centrifugal extractor for butyric acid extraction. Specific operation process: inject organic wastewater and extractant into the centrifugal extractor according to a certain ratio, and quickly mix the two phases by the drum. The mixed liquid is quickly separated by the centrifugal force of the equipment, and then discharged from the machine through different outlets.

The organic phase after extraction is in the extractant. If the subsequent process is carried out directly, the extractant will be wasted. The centrifugal extractor can be used for back extraction to extract and recover the extractant in the organic phase for recycling. The raffinate after the organic matter is extracted has reached the biochemical standard and can be processed in the biochemical stage.

The operating process of centrifugal extractors in chemical organic wastewater treatment is very mature. We can formulate reasonable operating processes and equipment selection for customers based on the feed liquid conditions.
