| titleOfInvention | Sludge dewatering agent and sludge dewatering method |
| abstract | PROBLEM TO BE SOLVED: To develop a dehydrating agent which can realize a coagulated state having good drainage and filter cloth releasability when dewatering sludge by a belt press or a filter press. Provided is an amphoteric polymer obtained by polymerizing a monomer mixture containing an acrylate-based quaternary ammonium base-containing monomer and a methacrylate-based quaternary ammonium base-containing monomer. Further, the present invention provides a method for efficiently dehydrating organic sludge using the amphoteric polymer. The acrylate-based quaternary ammonium base-containing monomer unit, the methacrylate-based quaternary ammonium base-containing monomer unit, the (meth) acrylic acid unit, the acrylamide unit, and the crosslinking agent unit are each in a specific ratio. This can be achieved by a sludge dehydrating agent comprising an amphoteric polymer contained in the above. After adjusting the pH of the sludge to 3 or more and less than 5, dehydration is performed using the amphoteric polymer, whereby an efficient dehydration method can be achieved. |
