titleOfInvention | Dewatering agent for membrane-separated sludge and method for producing dewatering agent for membrane-separated sludge |
abstract | (57) [Problem] To provide a dehydrating agent exhibiting excellent coagulation dewatering performance for sludge mainly composed of excess sludge generated from a biological treatment apparatus of a membrane separation type, and a method for producing the same. SOLUTION: Reverse-phase emulsion polymerization of a water-soluble cationic vinyl monomer represented by a specific formula or a mixture thereof and a monomer containing a bifunctional monomer is carried out in the presence of a chain transfer agent. A mixture of the obtained polymer and a hydrophilic surfactant called a phase inversion agent, diluted with water to a concentration to be added to sludge, particles having a particle size of 30 μm or less are observed under a microscope, and the diluted solution Can be achieved by a dehydrating agent having a property of forming a continuous dried film when applied to a glass plate and dried at 105 ° C. |
