The invention discloses a novel antiscalant and bactericide for water treatment and a preparation method thereof, which is characterized in that it consists of the following raw materials (by weight): 14-18 parts of sulfoacetic acid, 7-9 parts of sodium hypochlorite, and 15-21 parts of urea , 18~21 parts of liquid caustic soda, 40~50 parts of bromine, 3~5 parts of hydrochloric acid, 5~12 parts of deionized water, through the halogenation of sulfoacetic acid and sodium hypochlorite to synthesize sulfoglycolic acid, alcoholization of halogenated sulfoacetic acid and Back-acidification, synthesis of sulfohydantoin from sulfoglycolic acid and urea, synthesis of dibromosulfohydantoin from sulfohydantoin bromination and other process steps to prepare scale inhibitors and fungicides. Scale and corrosion inhibition effect; keep the circulating water quality stable, and greatly reduce the sewage caused by the sudden sterilization of algae; with the long-term stable addition of chemicals, the dosage of bactericide and algaecide will be significantly reduced. |
