| 摘要 |
The invention relates to a drink water filtering system which comprises an ozone generator, an active carbon groove, and a hollow filament membrane filtering device. The hollow filament filtering device is provided with hollow filament with average aperture diameter of 0.001 mu m to 1 mu m for filtering the raw drink water, and is positioned at the upstream of the ozone generator or at the downstream of the active carbon groove. The hollow filament membrane filtering device comprises a pair of hollow filament membrane filtering components, wherein a raw water feeding path is connected to the raw water feeding header respectively through a switch valve, a filtered water discharge path is respectively connected with a common filtered water discharge header, the switch valve is disposed on the filtered water discharge header, and the raw water return path is respectively connected to the common raw water return header through the switch valve; the hollow filament filtering device is configured to be a switch operation through a switch valve and can carry out reverse washing between a pair of hollow filament filtering membrane components. |
