Meanwhile, the negatively charged bacteria in the water are forcibly discharged and killed by the positive electrode; excess OH of calcium and magnesium ions in the cathode region^-Under the action of (1), the generated magnesium hydroxide precipitate is filtered and removed; heavy metals, residual pesticides and bleaching powder are adsorbed and removed by a flocculating constituent with strong adsorption capacity; cu²⁺、Zn²⁺The electric field between the polar plates kills the algae. Thereby achieving the purification purposes of turbidity reduction, sterilization, softening, algae removal, heavy metal removal, pesticide residue removal, bleaching powder and the like. Because the aluminum, iron, copper, zinc and other ions are filtered and removed together with the polymerized dirt, the salt content of water is not increased. In addition, a large amount of active oxygen atoms generated by the reaction on the inert polar plate have strong oxidizability, bacteria, pesticides, pigments, ammonia, nitrite and the like in water can be oxidized and decomposed, and redundant oxygen atoms are combined into oxygen molecules to be dissolved in the water to play a role in increasing oxygen. The hydrogen atoms generated on the cathode have reducing properties, which can decompose the nitrate. The hydrogen ions and the hydroxide ions participate in the reaction, and when one of the ions is excessive, the one is absorbed by the reaction first, so that the PH of the water is always neutral.

Because theelectric controller of the water purifying device adopts protective measures such as an isolation transformer and the like, the use is safe and reliable; the clamping circuit can automatically adjust the output pulse width of the time-base integrated circuit according to the conductivity of the treated water, when the conductivity of the water is strong and the current is large, the output pulse width automatically narrows, otherwise, the output pulse width automatically widens, therefore, the water purifying device has reliable performance and stable treatment effect no matter in the water with a large salt content; meanwhile, the problem of reduced processing capability caused by passivation of the polar plate can be solved. Because the electric controller adopts an intelligent automatic control technology, the operation is simple and convenient; the circuit has reasonable design and low power consumption, and has good economical efficiency.
