Treatment of wastewater from sebacic acid production by melting Halar high-parameter centrifugal extractor

Using melting Halar centrifugal extractor to treat wastewater from sebacic acid production, the structures, technical parameters and working principles of the said centrifugal extractor were introduced; furthermore, the improvement of centrifugal extractor structure for satisfying the specification of melting Halar process was introduced. The results of a project example showed that, through the extraction by the said extractor, the recovery rate of phenol in the wastewater from sebacic acid production reached above 99%, the mass concentration of phenol decreased to 35 ～ 40 mg/L, which could meet the requirement of influent water quality of the following biochemical system.
