Mounting rod, the mounting rod is installed in the mounting seat, and the lower end of the inner cylinder portion of catchmenting passes through the end socket, described
The bottom of outer cylindrical portion is connected to the bottom plate of a horizontally disposed ring-type, and the madial wall of the bottom plate is connected to described catchment
The lateral wall of inner cylinder portion, the lateral wall of the bottom plate are withstood on the madial wall of the shell；Opened on the top of the outer cylindrical portion
Provided with some first water holes, set in the region catchmented in inner cylinder portion and between the bottom plate and the top plate portion
Some second water holes are equipped with, activated carbon filtering body are filled with the chamber between the outer cylindrical portion and the shell, in institute
Stating the volume on the outside of inner cylinder portion that catchments has membrane body to be overlapped mutually the NF membrane group to be formed with screen cloth, on the bottom plate and is located at institute
The region stated between outer cylindrical portion and the inner cylinder portion of catchmenting is provided with the 3rd water hole；Be provided with the housing water inlet with
And concentrated water outlet, the water inlet and concentrated water outlet are located above and below the bottom plate respectively.
The water inlet is located at close to the position of the bottom plate.
Sealing ring is provided between the top plate portion and the mounting seat.
Be provided with boss on the madial wall of the shell and positioned at the position close to the bottom plate, the bottom plate with
Sealing ring is provided between the boss.
Using above-mentioned technical proposal, NF membrane of the present utility model, current are after water inlet enters enclosure, upwards
It is mobile simultaneously to be filtered first by activated carbon filtering body, then by the first water hole enter outer cylindrical portion between inner cylinder portion of catchmenting from
And filtered by NF membrane group, the clear water after filtering is entered on the inside of inner cylinder portion of catchmenting and discharged by the second water hole, is filtered
Concentrated water afterwards is discharged by being exported again by concentrated water after the 3rd water hole.NF membrane of the present utility model, before nanofiltration is carried out
Primary filter is carried out by activated carbon filtering body first, then carries out nanofiltration again, so as to ensure that the water quality of nanofiltration process is higher,
Extend the service life of NF membrane group.
