Many chemical companies produce a large amount of phenol wastewater during the production and processing process. Such wastewater is prohibited from being discharged directly. If it is sent to a sewage treatment plant for biochemical treatment, the biochemical cost will be quite high due to the high phenol content and high COD value. In response to this problem, Zhengzhou Tiei Extraction Technology uses the centrifugal extractor to pre-treat the wastewater by solvent extraction, extract and recover phenol, and then biochemically treat the wastewater, achieving the best of both worlds!
The phenol content in phenol wastewater is generally high. It is first pretreated, phenol is extracted and reused, and COD is reduced to the standard for biochemical treatment. This can not only recycle resources, but also effectively reduce biochemical costs. It is the method currently chosen by enterprises.
CWL-M Centrifugal Extractor is a liquid-liquid extraction and separation equipment, mainly used for the extraction, separation, washing, stripping and other operations of two-phase liquids. The reason why CWL-M centrifugal extractor is selected for operation is that centrifugal extractors have been widely used in the field of environmental protection. A large amount of experimental data and related cases prove the utilization rate of centrifugal extractors in the environmental protection industry.
The process method used with the centrifugal extractor is solvent extraction. Solvent extraction is the process of extracting phenol from wastewater using an extractant for recovery and treatment. The operation is simple and convenient, the extractant is cheap and easy to obtain, and the extraction efficiency is high. The treated wastewater can be directly treated in the biochemical section.
Before customers purchase centrifugal extractor, we usually use a small amount of feed liquid and the laboratory centrifugal extractor to test. The feed liquid and the selected extractant are injected into the centrifugal extractor through different feed ports according to a certain ratio. The organic components in the feed liquid are transferred to the extractant through the mixed mass transfer of the equipment. Then the light and heavy phases of the liquid are separated by the centrifugal force of the equipment and discharged from the body to realize the extraction process.
Compared with other traditional extraction equipment, the working principle of CWL-M centrifugal extractor is fundamentally different. Centrifugal extractor relies on centrifugal force to quickly mix and separate two phases. It has fast mixing and mass transfer speed and high extraction efficiency. It is widely used in many fields.
