Abstract

The invention relates to a preparation method of a sodium hypochlorite composite solution, raw materials comprise 73-83 parts by mass of a sodium hypochlorite solution, 1-5 parts by mass of starch, 15-18 parts by mass of crystalline dextrose, 1-5 parts by mass of diatomite and 10-20 parts by mass of water, and the preparation method comprises the following steps: (1) adding water into a sealed tank, and stirring uniformly; (4) adding a certain amount of a sodium hypochlorite solution into the sealed tank; (5) adding crystalline dextrose into the sealed tank; (6) adding the rest 1 / 3 of the sodium hypochlorite solution into the sealed tank and stirring; (7) adding diatomite into the stirred solution; according to the invention, a physical and chemical organic combination mode is adopted to purify the water body, so that the water quality purification treatment effect is relatively good.

Description

technical field [0001] The invention relates to the field of water purifying agents for environmental pollution treatment agents, in particular to a preparation method of a sodium hypochlorite composite solution. Background technique [0002] At present, most of the existing drinking water purifiers and flocculants use a single chemical component or a combination of a single chemical component and an inorganic flocculant to purify the water body. , will produce residues of harmful elements, and the reaction between inorganic flocculants and water bodies is slow, and it is easy to cause secondary pollution. Contents of the invention [0003] The object of the present invention is to provide a preparation method of a sodium hypochlorite composite solution, which uses a combination of physics and chemistry to treat water bodies, reducing the generation of secondary pollution. [0004] In order to achieve the above objectives, the following technical solutions are provided: ...
