Embodiment 1

[0061] Such as figure 1shown.

[0062] An intelligent chlorine-free disinfection and sterilization system for tap water, which includes:

[0063] One reaction box 5, this reaction box 5 is used for generating the required peroxyformic acid of sterilization, temperature sensor and liquid level sensor are installed in the reaction solution, when the reaction temperature in the reaction box is higher than the set value (as 4 degrees centigrade and ), the sensor immediately notifies the intelligent control device to start the compressor for refrigeration, and when the amount of peroxyformic acid in the reaction tank 5 exceeds the set liquid level, the liquid level sensor immediately notifies the intelligent control device to close the formic acid delivery pump and the hydrogen peroxide delivery pump Stop supplying the raw material formic acid and hydrogen peroxide needed for reaction in the reaction box;

[0064] One dosing metering pump 6, this dosing metering pump 6 is used to...

Embodiment 2

[0078] Such as figure 1 shown.

[0079] An intelligent high-efficiency chlorine-free disinfection and sterilization method for sewage. Take 0.1-3 liters of sulfuric acid with a concentration of more than 95% and add 100 liters of formic acid with a concentration of 30% to stir evenly and send it into the reaction box 5. 50 liters or 200 liters) hydrogen peroxide with a concentration of 30% reacts in the range of 0-4°C to generate peroxyformic acid (reaction efficiency is 90% according to calculation), and add peroxyformic acid to the sewage at a dose of 5-20PPM , quickly dissolves in water within 60 seconds and decomposes into carbon dioxide and water, completes disinfection and sterilization during the decomposition process, and realizes the cleaning of tap water.

[0080] When the concentration of formic acid, hydrogen peroxide and sulfuric acid changes during specific implementation, adaptive adjustment should be made according to the ratio of this embodiment.

[0081] Co...

Abstract

The invention discloses an intelligent disinfection and sterilization system and method for chloride-free tap water. The system is characterized by comprising a formic acid storage box (1), a hydrogen peroxide storage box (2), a reaction box (5), an addition metering pump (6), a cooling device and an intelligent control device, wherein the input end of the addition metering pump (6) is connected with the output end of the reaction box (5), the output end of the addition metering pump (6) extends into a water outlet of a tap water plant through a water pipe, performic acid with low dosage is rapidly dissolved into water, achieves disinfection and sterilization within 60 s and rapidly decomposed into water and carbon dioxide, and the input end of the reaction box (5) is connected with the output end of the formic acid storage box (1) and the output end of the hydrogen peroxide storage box (2). The intelligent disinfection and sterilization system is high in disinfection and sterilization efficiency, has no residue, and is low in running cost and convenient to maintain.

Description

technical field [0001] The invention relates to a water treatment technology, in particular to a tap water treatment technology, in particular to an intelligent chlorine-free disinfection and sterilization system for tap water. Background technique [0002] Disinfection and sterilization technology is widely used in the field of water treatment and is one of the important means of water treatment process. The existing disinfection and sterilization technologies mainly include the following categories: [0003] 1. Chlorine disinfection and sterilization. Such as: chlorine gas, sodium hypochlorite, chlorine dioxide, etc. [0004] 2. Ultraviolet disinfection and sterilization. [0005] 3. Ozone disinfection [0006] 4. Disinfect and sterilize with hydrogen peroxide. [0007] 5. Other disinfection methods: photocatalytic technology, electric field disinfection technology, (copper-silver) alloy disinfection technology, etc. [0008] The main problem that above-mentioned ste...
