Recycling device and method for treating wastewater produced during extraction of ginkgo flavonoids from ginkgo leaves
PendingCN110002616AEliminate odorImprove cleanlinessTreatment involving filtrationMultistage water/sewage treatmentFixed frameWastewater
The invention discloses a recycling device and method for treating wastewater produced during extraction of ginkgo flavonoids from ginkgo leaves and relates to the technical field of wastewater utilization. The device comprises a bottom plate, a precipitation tank and a fixed frame, wherein the bottom of the precipitation tank is fixedly connected with one side of the top of the bottom plate, thebottom of the fixed frame is fixedly connected with the other side of the top of the bottom plate through support legs, the top of the bottom plate is fixedly connected with a support plate through asupport rod, the top and the bottom of one side of the precipitation tank are communicated with a water inlet pipe and a blow-off pipe respectively, a partition plate is fixedly connected between topsof two sides of the inner wall of the precipitation tank, and round holes are formed in one side of the top of the partition plate. The recycling device for treating wastewater produced during extraction of ginkgo flavonoids from the ginkgo leaves can precipitate and filter impurities in the wastewater, has better effects than traditional tretament manners and can prevent filter difficulty causedby blockage due to impurity accumulation, so that the practicability of the wastewater treatment device is greatly improved.
