Problems solved by technology

The idea is to first generate chlorine dioxide gas, and then adsorb it in an inert carrier, use a release agent to release chlorine dioxide for disinfection, and its disadvantages are: the inert carrier is insoluble in water, polluting the disinfection object and the environment, Because inert substances will generate pollution, garbage
It is a multi-component product, which is inconvenient to carry and use
Chlorine dioxide content is low, which affects the disinfection effect
There is also a solid chlorine dioxide product in which the raw material and the activator are separately compressed into tablets. When used, it is mixed in water in proportion to use. This product is also a multi-component and two-component product, which is inconvenient to use.

Embodiment approach 1

[0006] Implementation Mode 1: The objects of disinfection are drinking water from urban waterworks and 121 rural rainwater harvesting projects. When in use, weigh 10 grams of powder chlorine dioxide disinfectant, dissolve it in 1 liter of water, and obtain a golden yellow clear and transparent solution within 5-10 minutes. The solution contains more than 800 mg of chlorine dioxide, and add it to 2.5 tons of tap water. Stir evenly, and the disinfection effect will be achieved after 30 minutes. At this time, the chlorine dioxide content in the drinking water is 0.3mg / L-0.1mg / L.

[0007] If it is the cellar water of the 121 rain collection project in rural areas, each cellar is calculated as 30 tons, weigh 120 grams of powdered chlorine dioxide disinfectant and dissolve it in 15 liters of water, and perform disinfection according to the above operation, and the disinfection effect will be achieved after 30-45 minutes. The chlorine dioxide content in its drinking water is 0.3mg / L...

Embodiment approach 2

[0008] Embodiment 2: The object of disinfection is hospital sewage. For every ton of sewage, 300 grams of powdered chlorine dioxide disinfectant should be weighed and dissolved in 30L of water. After 15 minutes, add the solution to hospital sewage. The chlorine dioxide content is 24mg / L. After 60 minutes, the water quality can reach GB48-83. Hospital sewage discharge standard and GB8978-88 national comprehensive sewage discharge standard.

Embodiment approach 3

[0009] Embodiment 3: Disinfection of hospital wards and environments. Take by weighing 1 gram of powdered chlorine dioxide disinfectant, dissolve it in 1 liter of water, add 160 liters of water to dilute (the chlorine dioxide content is 0.5mg / L) after 15 minutes, spray, scrub and disinfect after 10-20 minutes.

Abstract

A solid ClO2 disinfectant for the drinking water, food and medical apparatus is prepared through mixing oxalic acid with citric acid, grinding, adding dextrin, activating, mixing with sodium chlorite, aluminium chlorate, glucose and sodium chloride, and packing.

Description

technical field [0001] The invention relates to a production method of a solid chlorine dioxide disinfectant, which is a powder and a tablet made of oxalic acid, citric acid, sodium chlorite, glucose, dextrin, sodium chloride and aluminum chloride. Background technique [0002] At present, the existing solid chlorine dioxide on the market can be roughly divided into two types: the first one is to mix different solid reaction raw materials together in a certain proportion, so that a slow chemical reaction occurs directly to release chlorine dioxide gas, For example, the "indoor air purifier" developed by Mr. Zheng Yansong of Xiangyang Teachers College in Hubei; or directly generate stable solid chlorine dioxide with a concentration many times higher than that of the stable chlorine dioxide solution, and add water to prepare the required concentration of stable chlorine dioxide during use. Chlorine dioxide solution can also be directly added to water for u...
