State controls first scouring electromagnetic valve 5 and closes, and second scouring electromagnetic valve 6 is closed, and the first reflux branch 3 closes
It closes, the second reflux branch 4 is closed, at this point, first check valve 31 is in close state, at the second one-way valve 41
In closed state, the third scouring electromagnetic valve 9 is closed.
Before raw water to be processed is through second on filter element 12 and second branch 2 before first in the first branch 1
After 22 primary filter of filter element, filtered again into the rear filter element 51.Filter element 12 and institute before described first
When filter element 22 was in using the later period before stating second, filter element 22 before the filter membrane and second before first in filter element 12
In filtering membrane flux reduce, certainly will be by filter element after reduction if continuing to intake only with the first branch 1 or second branch 2
51 water yield, at this point, by raw water to be processed through the first branch 1 and second branch 2 enter simultaneously it is described after filter element 51,
It can effectively avoid the problem that rear 51 water yield of filter element reduces.
When the flux of the preceding filter core is greater than or equal to predetermined value, the water treatment system alternate run the is controlled
One mode first time period, the second mode second time period, to increase the service life of the filter core in the preceding filter element, when
When the flux of the preceding filter core is reduced to predetermined value, the water treatment system operation the third mode is controlled, is used with alleviating
The problem of later period flux reduces.
Those skilled in the art will readily recognize that above-mentioned each preferred embodiment can be free under the premise of not conflicting
Ground combination, superposition.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field
