| titleOfInvention | Composition, amphoteric polymer flocculant and method for dewatering sludge |
| abstract | (57) [Summary] [Problem] To provide a composition, a polymer flocculant, and a method for dewatering sludge having excellent coagulation and dewatering performance with respect to various sludges, and particularly with respect to sludge having a large surplus ratio. . The amphoteric polymer includes two types of amphoteric polymers (hereinafter, referred to as amphoteric polymers 1 and 2) having a cationic monomer, an anionic monomer, and a nonionic monomer as essential units. Of the monomer units satisfy the following formulas (1) to (3), In addition, a composition in which the nonionic monomer units constituting all amphoteric polymers in the composition are 60 mol% or more, an amphoteric polymer flocculant containing the composition, and a method of dewatering sludge using the flocculant . Ca 1 / An 1 ≧ 1 ・ ・ ・ (1), Ca 2 / An 2 ≧ 1 ・ ・ ・ (2), │ (Ca 1 -An 1 )-(C a 2 -An 2 ) │ ≧ 1.5 (3) [In the above formulas (1) to (3), Ca 1 and An 1 are each a total of all the constituent monomers in the amphoteric polymer 1. Quantity 10 It represents the number of moles of all cationic monomer units and all anionic monomer units when converted to 0 mol, and Ca 2 And An 2 each represent the same mole number in the amphoteric polymer 2 as described above. ] |
