| titleOfInvention | Sludge dewatering method |
| abstract | (57) [Abstract] [Problem] To form large agglomerated flocs with good filterability, Provided is a method for dehydrating sludge, which can obtain a good cake having a low water content by mechanical dehydration and can perform stable treatment. SOLUTION: An inorganic coagulant is added to surplus sludge generated in the treatment of activated sludge of organic waste water, and further 20 to 90 mol% of vinylamine salt unit, 5 to 75 mol% of N-vinylformamide unit and acrylic acid or the same. Salt unit 2 A sludge dewatering method comprising adding 40% by mol of an amphoteric polymer flocculant for dehydration. |
