Embodiment Construction
[0018] The present invention will be further described below in conjunction with specific examples.
[0019] The chemical name of dibromohydantoin of the present invention is 1,3-dibromo-5,5-dimethylhydantoin, referred to as: DBDMH, and its molecular formula is C 5 h 6 o 2 N 2 Br 2 , Dibromohydantin is light yellow crystalline powder, slightly soluble in water, soluble in chloroform, ethanol and other organic solvents, stable when dry, easy to decompose in strong acid or strong alkali, can be further processed into granules and tablets, and its disinfection is the most effective The optimal pH value is 5-7, and the residue after disinfection can be biodegraded in a short time without any pollution to the environment. Dibromohydantoin can continuously release Br in water - ions to form hypobromous acid, the reaction formula is: C 5 h 6 o 2 N 2 Br 2 +2H 2 O→C 5 h 8 N 2 o 2 +2HOBr. Hypobromous acid can oxidize and decompose the microcystins produced after the deat...
