Abstract

The invention discloses a water treatment agent for recovering reclaimed water and a preparation method thereof. The water treatment agent comprises the following raw materials in parts by weight: 2-4 parts of dodecyldimethylbenzyl ammonium chloride, 1-3 parts of isothiazolinone, 2-4 parts of anhydrous citric acid, 2-4 parts of sodium hexametaphosphate, 5-7 parts of zinc sulfate, 12-14 parts of copper sulfate, 6-8 parts of quicklime, 6-8 parts of sulfur, 10-12 parts of ferrous sulfate, 5-7 parts of activated silica, 2-4 parts of isoleucine, 2-4 parts of polyepoxysuccinic acid, 1-3 parts of calcium hydroxide, 8-10 parts of polyacrylamide, 2-4 parts of sodium hypochlorite, 5-7 parts of ethylenediamine tetra(methylenephosphonic acid), 2-4 parts of poloxamer, 5-7 parts of polyvinylpyrrolidone, 3-5 parts of sodium bicarbonate and 1-3 parts of dipotassium glycyrrhetate. The water treatment agent for recovering reclaimed water has excellent purifying capacity and sterilization capacity.

Description

technical field [0001] The invention relates to a water treatment agent for reuse of middle water and a preparation method thereof. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. Sewage treatment: The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] However, the current sewage treatment agents are inconvenient to use, and usually do not have the ability t...
