| titleOfInvention | Sludge dewatering method |
| abstract | 【Task】 The general prescription for suppressing the increase in cost due to an increase in the amount of the polymer flocculant is to use an inorganic flocculant in combination, but using an inorganic flocculant increases the amount of dewatered sludge, as well as the environment and health. There are concerns. The subject of this invention is providing the prescription which does not increase the addition amount of a polymer flocculent, even if it does not use an inorganic flocculant together as a method of dehydrating sludge with few fiber content efficiently. [Solution] A method for dewatering sludge in which a water-soluble cationic polymer is added to a sludge having a pH value of 5 to 8, followed by addition of a water-soluble amphoteric polymer and then dewatering, wherein the water-soluble cationic polymer This can be achieved by using a water-soluble cationic polymer whose molecule has a charge inclusion rate expressed by definition of 50% or more and 90% or less. [Selection figure] None |
