Purified water is discharged in second water outlet；Second discharge outlet is communicated with flush cycle pipeline 5, the flush cycle pipeline 5
It is connected to the ultrafiltration membrane filter element component 1 and the concentrated water pressurized tank 6, and the flush cycle pipeline 5 and the ultrafiltration membrane filtration
First switch 71 is provided between core assembly 1.
Raw water is filtered by water inlet pipe 8 into ultrafiltration membrane filter element component 1, and filtered water is further across reverse osmosis diafiltration
Core assembly 3 filters.The concentrated water that reverse osmosis 3 filter process mesohigh side of element kit generates is expelled to by flush cycle pipeline 5
In concentrated water pressurized tank 6, it is collected by the water purification after reverse osmosis filter element filtering by the outflow of the second water outlet or continues to transmit.
The first switch 71 is opened, so that the concentrated water of the reverse osmosis element kit 3 discharge is by the flush cycle pipe
Road 5 flow to the ultrafiltration membrane filter element component 1, and to 1 back flush of ultrafiltration membrane filter element component, the concentrated water after flushing is by ultrafiltration membrane filter element
First discharge outlet of component 1 is discharged.
Since ultrafiltration membrane filter element component 1 can carry out primary filtration to raw water, bulky grain suspended matter, colloid etc. can be trapped in super
At filter membrane element kit 1, it is nothing that reverse osmosis element kit 3, which is filtered in the concentrated water of generation water, which has no bulky grain suspended matter,
The higher solution of machine salt ionic concentration, may be implemented the flush applications to ultrafiltration membrane filter element component 1.By with the ultrafiltration membrane filtration
