Background
In modern life and industry, the sterilization and disinfection of water mainly rely on the introduction of a certain amount of oxidants, such as hydrogen peroxide, sodium hypochlorite and the like, and rely on the oxidative decomposition of organic dirt and the oxidation and sedimentation of partial ions.
In practical use, because the amount of the introduced oxidant is difficult to accurately control, or the oxidation-reduction reaction product is easy to dissolve in water, and the like, a certain amount of chemical substances which have adverse effects on human bodies or production and life are often left in water; or incomplete reaction caused by insufficient amount of introduced reactants, thereby reducing the sterilization effect, or leaving toxic and harmful organic matters which are not completely decomposed in the water body.
The electric field activated water module is used on the principle that a certain voltage is applied between electrodes to generate an electric field and a certain current is generated in a water body. Under the catalytic action of noble metal oxide, free hydroxyl group with strong oxidizing property, hydrogen ion and free electron are generated. The hydroxyl group acts as an oxidant in the water body to complete the purification of the water body.
After the voltage applied between the electrodes is released, the hydroxyl group is highly unstable in the water solution and rapidly reacts with hydrogen ions and free electrons to generate water, so that the residual effect of the water purifying agent or the disinfectant in the water body is eliminated.
