| titleOfInvention | Sludge dewatering method |
| abstract | (57) [Object] To provide a sludge dewatering method capable of stably and efficiently dewatering organic sludge including biologically treated sludge generated from sewage, night soil, industrial wastewater, and the like. SOLUTION: For organic sludge, general formula [1], It has structural units represented by [2] and [3], the number of structural units of general formula [1] is equal to or greater than the number of structural units of general formula [3], and the intrinsic viscosity measured at 30 ° C. 7 dL / g or more, the value of the gradient k ′ in the formula [4] is in the range of the formula [5], the spinning length of the 0.4% by weight aqueous solution at 30 ° C. is in the range of the formula [6], A sludge dewatering method in which an amphoteric polymer having an extrapolated viscosity of 1,500 to 3,500 mPa · s at 1 rpm of a 0.2% by weight aqueous solution at 30 ° C. is added and dewatered. η sp / c = [η] + k′c (dL / g) [4] k ′ = (15.8 × [η] -101.1) ± 10.0 (dL 2 / g 2 ) [5 ] Yarn length = (12.9 x [η]-74.4) ± 10.0 (mm) ...
