PROBLEM TO BE SOLVED: To provide an organic coagulant excellent in coagulation and decoloring effect, and a polymer coagulant excellent in characteristics such as floc coarsening, floc strength increase, low water content of dehydrated cake, filtrate decolorization and COD reduction. I will provide a. A monomer represented by general formula (1) or a salt thereof (a), or a monomer represented by (a) and general formula (2) or a salt thereof (b) is an essential constituent unit (co-polymer). ) An organic coagulant characterized by comprising the polymer (A), (CH 2 = CR 1 -CH 2 ) 2 R 2 N (1) (CH 2 = CR 3 -CH 2 ) 2 R 4 N (2) [Wherein, R 1 and R 3 represent H or a methyl group, R 2 represents an arylalkyl or alkylaryl group, and R 4 represents H or an alkyl group having 1 to 16 carbon atoms. ] And a polymer flocculant comprising a combination of the organic coagulant and another water-soluble (co) polymer.
