Embodiment 1

[0011] In the filter container, there is a composite filter medium layer consisting of an ordinary neutral and fast filter paper on the upper layer and an inorganic microporous filter membrane (0.45 μm in aperture) on the lower layer, and then the zedoary oil is put into production After the previous pretreatment, the remaining discarded liquid is placed in it for filtration, and the clarified filtrate is collected, which can be used for production and reuse, and the filtered precipitate is discarded.

Embodiment 2

[0013] The filter container is provided with a composite form filter medium layer consisting of an upper layer of ordinary filter paper and a lower layer of an organic microporous membrane (pore size 0.22 μm), and then the remaining The discarded liquid is placed in it for filtration, and the clarified filtrate is collected, which can be used for production and reuse, and the filtered precipitate is discarded.

Abstract

A process for recovering the waste liquid generated by pre-treating zedoary oil features that said waste liquid containing deposits is filtered by the filter whose pore diameter is greater than 0.65 m and then by another filter whose pore diameter is 0.2-0.65 m. Its advantage is high effect.

Description

technical field [0001] The invention relates to a method for recycling the remaining waste liquid after pretreatment of zedoary oil, which can be used as the active ingredient of antiviral and anticancer drugs. Background technique [0002] Zedoary oil is an active ingredient that can be used in pharmaceuticals as an antiviral and anticancer drug. In the current production process, zedoary oil generally needs to be pretreated at 0°C to 4°C before it is put into production, so that the low-temperature insoluble impurities with black and / or white color will settle at the bottom, and then Take the supernatant and put it into the next step of production to ensure and improve the clarity of products such as zedoary oil and glucose injection, and prevent suspension and / or sediment such as small black spots during storage. After the pretreated supernatant is taken away, most of the remaining black turbidity still contains part of the residual zedoary oil component, which is genera...
