Electrolyzed water sterilization device and sterilization method

Abstract

The invention provides an electrolyzed water sterilization device, which comprises a shell, wherein an upper electrode and a lower electrode are arranged in the shell; an electrode isolating plate used for isolating a cathode and an anode of the electrodes and keeping a distance between the electrodes is arranged between the upper electrode and the lower electrode. After the device is electrified, the upper electrode and the lower electrode decompose a water molecule into an hydrogen ion (H+) and an oxygen ion (O-), the oxygen ion used as a negative ion is reacted with other peripheral water molecules to generate hydroxide radical (OH-), at the time, a small amount of sodium hypochlorite (HOCL) containing microamount chloride components existed in tap water is also decomposed into HCL+ and O-, and dissolved oxygen (O-, O3-) negative ions and hydrogen peroxide sterilization substances are produced, so that water is sterilized. The electrolyzed water sterilization device provided by the invention is applied in titanium electrode electrolysis, can achieve a sterilization effect without influencing water quality. The device has high design reliability, a long life, a good sterilization effect, low cost, no need for adding a sterilizing agent, and no secondary pollution.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection, in particular to an electrolyzed water sterilization device and a sterilization method. Background technique [0002] Water treatment sterilization is currently generally used to add chlorine or chloride to the water oxidation disinfection method. However, it was found that chlorination would lead to the production of "three causes" (carcinogenic, teratogenic, and mutagenic) substances in drinking water. Treatment methods such as ultraviolet rays, ozone, ultrasonic waves, magnetization, and electrostatics developed in recent years have not been widely used due to complex equipment, low flow rate of treated water, or high treatment costs. [0003] With the development of industry, water sources are increasingly polluted by various organic substances, and the traditional chlorination disinfection method of water supply system has been found to form harmful substances to huma...
