▎ 摘　　要

NOVELTY - Water treatment device based on visible light catalytic forward osmosis separation membrane, comprises a raw water storage chamber with a liquid inlet on the side wall of the first layer, and a light-transmitting quartz glass on the upper end, and a visible light lamp fixed by a partition at the center above the glass and a membrane filter unit. The extraction tank and its interior are equipped with a temperature control system. The second layer is the pure water storage room, which is composed of an automatic replenishment device for the extraction agent and a liquid outlet. The filter unit is provided with a nitrogen-doped titanium dioxide/reduced graphene oxide (N-/regenerated graphene oxide/polyvinylidene fluoride) new photocatalytic composite membrane for purifying and separating polluted water. USE - The water treatment device is useful for separating the photo-catalysis and the forward osmosis membrane separation technology separately to process the water, where the water is waste water treatment, seawater and brackish water desalting, sludge digestive juice and garbage percolate processing, food concentration and drug release and remote exploration and field emergency rescue. ADVANTAGE - The device combines the photo-catalysis technology and the positive osmosis membrane separation technology in the same device and application, using visible light after decontamination and sterilizing effect are obviously improved, avoiding or reducing the membrane pollution, at the same time, reducing the manufacturing cost and floor area of the device. The device has high water treatment efficiency, simple structure, good water purifying effect, and combined with wide application prospect. DESCRIPTION OF DRAWING(S) - The drawing shows a view of a visible light device of a water treatment device based on visible light catalysis and forward osmosis separation membrane.
