Embodiment Construction

[0018] The present invention is described in further detail below by way of example: a kind of water treatment dechlorination sheet, contains sodium sulfite active ingredient 70~91% (percentage by weight), a kind of mixed solution of coloring water and aqueous syrup binder 0.5~4.2% (percentage by weight), 0.05-1% (percentage by weight) of a stearate dissolution rate controller, and 2-3.75% (percentage by weight) of an inert excipient, such as materials such as talcum powder. For the convenience of demoulding, the chlorine-removing sheet may further contain a stearate mold release agent in an amount of 0.05-1% (percentage by weight). The mixed liquid of described coloring water and aqueous syrup binding agent is the mixture of commonly used aqueous edible syrup and a small amount of food dye liquid, and aqueous edible syrup can be selected from such as malt syrup mixture, sucrose syrup mixture, milk syrup mixture, sugar beet One or a mixture of syrup mixtures, corn syrup mixtur...

Abstract

A dechlorination tablet for water and wastewater treatment contains 70 to 91 weight percent active sodium sulfite, 0.5 to 4.2 weight percent mixture solution of color liquid and liquid sugar binder, 0.05 to 1 weight percent one type of stearate salt used as dissolution rate control chemical, 0.05 to 1 weight percent another type of stearate salt used as mold release chemical, and 2 to 3.75 weight percent inert material, such as talc powder. The method of making the tablet comprises mixing the materials completely, pouring the mixture into a mold of a tabletting press, and pressing the mixture into a tablet at a pressure of between 7,000 kilograms and 25,000 kilograms. The density of the formed tablet is from 1.7 to 2.1 gram / cm3. Then, the formed tablet is dried between 70° C. and 130° C. for between one-half and three hours.

Description

technical field [0001] The present invention relates to improving the water quality of certain drinking water and industrial water by adding specific substances, or improving the water quality of treated waste water, more specifically, it relates to the removal of chlorine, oxygen and iodine in the process of water treatment. Reagents and their preparation methods. Background technique [0002] Halogen elements such as chlorine, Australia, and iodine in the water seriously affect the water quality. U.S. Patent No. 4,364,835 uses sulfur dioxide, or soluble sulfite, or bisulfite to reduce non-volatile residual chlorine in water. This type of non-volatile residual chlorine exists in chlorinated drinking water, domestic sewage and industrial in wastewater. Sulfites are effective in removing residual chlorine from water, or at least destroy most of the non-volatile residual chlorine. The further improved U.S. Patent No. 4,816,177 uses a protein organic jelly binder to produce ...
