Title:
APPRATUS AND METHOD FOR FILTRATING OIL-CONTAINING DRAINAGE WATER, AND METHOD AND APPARATUS FOR RESTORING FILTRATION MEMBRANE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/116005
Kind Code:
A1
Abstract:
Provided are: an oil-containing drainage water filtration apparatus which is compact in size and rarely undergoes the adhesion of an oil-containing solid matter; and an oil-containing drainage water filtration method. An oil-containing drainage water filtration apparatus 1 is provided with: a membrane immersion vessel 2 into which oil-containing drainage water is introduced; a filtration membrane device 3 which is immersed in the oil-containing drainage water introduced in the membrane immersion vessel 2 and can filtrate the oil-containing drainage water; and a stirrer 8 which is installed in the membrane immersion vessel 2 and can stir the oil-containing drainage water stored in the membrane immersion vessel 2. An oil-containing drainage water filtration method comprises: introducing oil-containing drainage water into a membrane immersion vessel 2 having a filtration membrane device 3 installed therein so as to immerse the filtration membrane device 3 in the oil-containing drainage water; and filtrating the oil-containing drainage water with the filtration membrane device 3 while stirring the oil-containing drainage water introduced into the membrane immersion vessel 2 with a stirrer 8 installed in the membrane immersion vessel 2.
