Problems solved by technology

[0004] The existing residual chlorine removal product is mainly based on sodium sulfite as an active ingredient. As the Chinese patent authorization announcement number CN1331771 discloses a water treatment chlorine removal tablet and a preparation method thereof, it aims at adopting a protein organic jelly adhesive that is easy to dissolve in the tablet. The shortcomings of foam and white floating objects in the water, choose to use water syrup binder to avoid secondary pollution
However, the remaining chlorine removal effect has not been studied

Embodiment Construction

[0041] A kind of chlorine removal material in water treatment, described chlorine removal material takes compound (I) as active ingredient, is mixed by compound (I), binder and vitamin H, and preparation method comprises the following steps:

[0042] Step 1: Dissolve 50% of the total amount of sodium carboxymethyl cellulose (CMC) in 15% of the total amount of ethanol solution containing 75% water and stir at 30°C to dissolve the sodium carboxymethyl cellulose into a gelatinous liquid;

[0043] Step 2: Slowly add compound (I) accounting for 30% of the total amount and vitamin H accounting for 5% of the total amount into the colloidal liquid and stir evenly to form a flour-like material;

[0044] Step 3: Use a granulator to granulate or manually knead granules with a mesh sieve to make wet tablets with a diameter of 3-5mm and a thickness of 3mm;

[0045] Step 4: Put the wet granules in an oven at 45-50°C, dry them for 0.5-1 hour, remove the solvent, and make a chlorine removal ...

Abstract

The invention relates to a dechlorination material in water treatment as well as preparation and use methods thereof. The dechlorination material is formed by mixing a compound (I), an adhesive and vitamin H together, the compound (I) is shown as the formula above. The preparation method comprises the following steps of: dissolving the adhesive into solvent to form colloidal fluid; adding the compound and vitamin H slowly into the colloidal fluid and stirring evenly for forming floury materials; granulating with a granulator or granulating by manually rubbing with a mesh sieve to make wet particles; and placing the wet particles into an oven for drying to make the dechlorination material. The invention has the advantages that the dechlorination material is a redox system of disordered non crystalline structure, has large void ratio, strong exchanging ability and long releasing period, can be used for specially treating residual chlorine in water with residual chlorine removing efficiency above 99 percent, and can be used for removing residual chlorine, iodine in tap water as well as other halogen elements, thereby achieving the aim of purification.

Description

technical field [0001] The invention relates to a chlorine removal material in water treatment and a preparation and use method thereof. Water quality is improved by making water flow through the chlorine removal material, especially for the removal of residual chlorine in domestic water. Background technique [0002] As we all know, liquid chlorine in tap water is the culprit of carcinogens. It is a time bomb lurking next to the human body, and the incidence of tumors in the digestive system is mostly related to it. Therefore, residual chlorine, chloroform, carbon tetrachloride, methyl iodide, and methyl bromide contained in water are all listed as carcinogenic, teratogenic, and mutagenic substances. [0003] In addition to the chlorine in drinking water, the capillaries on the skin surface are in a dilated state during bathing. At this time, the free chlorine in hot water or water vapor will be absorbed through the skin, causing skin itching, cracking, aging and dryness. ...
