[0002] The traditional disinfection methods in hospitals are to purchase disinfectants and disinfectants from outside. The residual liquid of this disinfectant may pollute the environment and greatly increase the operating cost of the hospital. If the hospital can produce disinfectants by itself, it will greatly reduce the cost of the hospital Operating costs can also reduce patient medical expenses

Abstract
The invention discloses a preparation method of acidic water and alkaline water, which includes the steps of: 1) preparation of soft water: preparing soft water through a water softening machine; 2) preparation of a NaCl solution: adding NaCl to the soft water to prepare the NaCl solution; 3) electrolysis: electrolyzing the NaCl solution, wherein the acidic water and alkaline water are formed respectively on a positive pole and a negative pole. In the method, through the electrolysis, H<+> and chlorine gas, which has strong activity, are formed on the positive pole, wherein the chlorine gas can be dissolved in water to form the strong acidic water, which is a colorless and transparent liquid, has a slight chlorine smell, is free of irritation on skin and mucosas and can kill various bacterial vegetative forms. The acidic water can be gradually reduced into common water during contact with air, light and organic substance, so that the acidic water is an excellent green disinfectant.
Description
technical field [0001] The invention relates to a preparation method of acidic water and alkaline water, belonging to the technical field of reagent preparation. Background technique [0002] The traditional disinfection methods in hospitals are to purchase disinfectants and disinfectants from outside. The residual liquid of this disinfectant may pollute the environment and greatly increase the operating cost of the hospital. If the hospital can produce disinfectants by itself, it will greatly reduce the cost of the hospital The operating cost can also reduce the patient's medical expenses. Acidified water is a new type of environmentally friendly disinfectant, which is widely used in the disinfection of endoscopes, oral cavity, and operating rooms. Acidified water is produced by processing ordinary tap water. Acidified water is gradually reduced to ordinary water in the process of contact with air, light, and organic matter. It is an ideal green disinfectant, and its envi...
