In an embodiment, the household water purifying apparatus further includes a Total Dissolved Solids (TDS) detecting component disposed on the first pipeline 210 for detecting a current TDS value of the tap water in the first pipeline 210. Wherein the electrically driven desalination assembly 100 comprises any one of an electrically driven single-channel desalination assembly and an electrically driven dual-channel desalination assembly; the electrically driven single-channel desalination assembly comprises at least one of a capacitive desalination cartridge, a membrane capacitive desalination cartridge, and a bipolar membrane (Biopolar, BP) electrodeionization cartridge, and the electrically driven dual-channel desalination assembly comprises at least one of an electrodialysis unit and a reverse-electrode electrodialysis unit.

It is understood that the electrically driven single-channel desalination module only uses one water inlet and one water outlet when purifying the water flowing through, and needs to be powered by the power supply module, and thus can be referred to as an electrically driven single-channel desalination module.
Specifically, as shown in fig. 2 and 3, the bipolar membrane electrodeionization filter cartridge 900 comprises one or more pairs of electrodes 910, and at least one pair of electrodes 910 has one bipolar membrane 920 or a plurality of spaced bipolar membranes 920 disposed therebetween. Wherein, bipolar membrane 920 includes cation exchange membrane 921 and anion exchange membrane 922, and cation exchange membrane 921 and anion exchange membrane 922 set up relatively, compound together. For example, the bipolar membrane 920 can be produced by a hot press molding method, a bonding molding method, a casting molding method, an anion and cation exchange radical method, an electrodeposition molding method, or the like. Specifically, there is no space between the cation exchange membrane 921 and the anion exchange membrane 922 on one bipolar membrane 920, for example, water does not pass between the cation exchange membrane 921 and the anion exchange membrane 922 on the same bipolar membrane 920 when flowing through the bipolar membrane electrodeionization filter cartridge 900.

Fig. 2 is a schematic diagram showing the operation principle of the bipolar membrane electrodeionization filter element 900 in the process of purifying water. Here, the potential of the first electrode 911 is higher than that of the second electrode 912, that is, a voltage in a forward direction is applied between the first electrode 911 and the second electrode 912. At this time, anions such as chloride ions in the raw water to be purified move towards the first electrode 911, and replace OH < - > in the anion exchange membrane 922 in the direction of the first electrode 911, and the OH < - > enters the flow channel between the adjacent bipolar membranes 920; meanwhile, cations such as Na + in the raw water move towards the second electrode 912 to replace H + in the cation exchange membrane 921 in the direction of the second electrode 912, and the H + enters the flow channel; h + and OH-are subjected to neutralization reaction in the flow channel to generate water, so that the salt in the raw water is removed, and purified pure water flows out from the tail end of the flow channel.
As shown in fig. 3, when a voltage in the opposite direction is applied between the first electrode 911 and the second electrode 912, so that the potential of the first electrode 911 is lower than that of the second electrode 912, OH "and H + ions are generated on the surfaces of the cation exchange membrane 921 and the anion exchange membrane 922 of the bipolar membrane 920 under the action of an electric field, cations such as Na + inside the cation exchange membrane 921 are replaced by H + ions and move toward the first electrode 911 at a low potential, anions such as chloride ions in the anion exchange membrane 922 are replaced by OH" and move toward the second electrode 912 at a high potential, and the cations such as Na + and the anions such as chloride ions enter the flow channel and can be washed out by water flowing through the bipolar membrane electrodeionization filter 900. Therefore, when the power is off or reverse voltage is applied to the desalting filter cores such as the bipolar membrane electrodeionization filter core 900 and the like, cations such as Na < + > and the like and anions such as chloride ions and the like adsorbed on the bipolar membrane 920 can be released, so that salt substances of the bipolar membrane electrodeionization filter core can be washed out by water, and regeneration is realized; water carrying cations such as Na + and anions such as chloride ions can be called concentrated water.
