The preposed filter element 11 can be used for pretreating raw water, is beneficial to protecting the booster pump 4 and the reverse osmosis filter element 5, and can also improve the purification effect of the raw water. The post-positioned filter element 12 can remove residual chlorine, peculiar smell, color and organic matters in the water again before purified water is provided for users to drink, thereby ensuring the quality of the drinking water finally provided for the users.
As shown in fig. 3, as another embodiment of the present invention, a water purification method convenient for TDS regulation is disclosed, which is applied to the water purification system, and comprises the following steps:
s100: the TDS meter detects a TDS value of purified water in the water storage device;
s200: according to the TDS value of the purified water in the water storage device, the waste water switch is regulated and controlled to control the drainage speed of the waste water pipeline.
According to the water purification method, the TDS value of the purified water is detected by the TDS meter 9, the waste water switch 8 is regulated to control the speed of the discharged waste water of the waste water pipeline 7, so that the TDS concentration of the water inlet side 51 of the reverse osmosis filter element 5 is controlled, the TDS concentration of the water outlet side 52 is regulated, and the TDS concentration of the purified water is regulated to a required value so as to meet the requirements of different regions or different people.
Specifically, the water purification method further comprises the following steps: and circulating the wastewater in the wastewater pipeline to the water inlet side of the reverse osmosis filter element through the wastewater pipeline.
Specifically, the water purification method further comprises the following steps: and completely starting a waste water switch to enhance the flushing of the reverse osmosis membrane by the water at the water inlet side of the reverse osmosis filter element. Open waste water switch 8 completely, improve the velocity of flow of waste water pipeline 7 discharge waste water, the inflow speed of the 51 former water of the side of intaking of reverse osmosis filter core 5 also can improve to it is bigger to reverse osmosis membrane's washing power, can effectually wash reverse osmosis membrane of reverse osmosis filter core 5, makes its life longer. More specifically, after the water purification system 2 produces water for a certain time, the waste water switch 8 is completely turned on. The specific time can be set according to the local water quality condition and the requirement of the user, and can be three days, five days, two weeks, one month and the like.
Specifically, the step S200 further includes: if the TDS value of the purified water in the water storage device is larger than a preset value, any one or any combination of the opening degree, the opening duration and the opening frequency of the waste water switch is increased so as to accelerate the drainage speed of the waste water pipeline; if the TDS value of the purified water in the water storage device is smaller than the preset value, any one or any combination of the opening degree, the opening time and the opening frequency of the waste water switch is adjusted to be small so as to slow down the drainage speed of the waste water pipeline. The preset value can be set according to the local water quality condition and the requirement of the user.
As shown in fig. 4, as another embodiment of the present invention, a water purifying apparatus is disclosed, the water purifying apparatus 1 includes the water purifying system 2 as described above.
