摘要

The present application refers to a method of treating an effluent containing sorbic acid and/or its salt which comprises a step of subjecting said effluent to membrane separation or to activated carbon treatment, and a step of subjecting the membrane downstream fluid or the activated carbon-treated effluent to biological treatment. Furthermore, the present application provides a device for effluent disposal comprising (1) a membrane separation means for separating an effluent containing sorbic acid and/or its salt or a means for treating said effluent with activated carbon, and (2) a biological means for treating the membrane downstream fluid or the activated carbon-treated effluent biologically.
