得ないのが実情である。 It is difficult to separate a water-soluble polymeric substance from an aqueous solution in which the water-soluble polymeric substance is dissolved. For example, even if wastewater containing water-soluble polymeric substances dissolved therein is treated with an activated sludge treatment method or a flocculant, almost no polymeric substances can be removed. Therefore,
Conventionally, wastewater containing these water-soluble polymer substances with high COD values (chemical oxygen demand) and BOD values (biochemical oxygen demand) has been processed by evaporating the water, concentrating it, and then burning it, which is a very complicated process. The reality is that we have no choice but to take appropriate measures.

もよい。 Examples of water-soluble polymeric substances that can be separated from aqueous solutions by the method of the present invention include water, alcohol, phenol, organic carboxylic acids, amines, amides, etc., and compounds having active hydrogen such as ethylene oxide or ethylene oxide and propylene oxide, butylene oxide, etc. Polyoxyalkylene compounds produced by adding both (random or block) with higher alkylene oxide, polyvinyl alcohol, partially saponified products of ethylene-vinyl acetate copolymer, partially saponified products of polyvinyl acetate , polyacrylamide, gelatin, etc. Examples of polyoxyalkylene compounds include polyethylene glycol, block or random copolymers of ethylene oxide and propylene oxide, block or random copolymers of ethylene oxide and butylene oxide, and the like. The higher the molecular weight, the easier the removal, and preferably those having about 5 or more monomer units, particularly about 10 or more monomer units. These aqueous solutions of water-soluble polymeric substances can be treated either with a high concentration of the polymeric substance, for example, an aqueous solution with a concentration of about 50% by weight, or with aqueous solution with a low concentration, such as an aqueous solution with a concentration of several ppm to several hundred ppm (by weight). . It is easier to remove polymeric substances with a highly concentrated aqueous solution. The aqueous solution may also have other substances dissolved or suspended in addition to the water-soluble polymeric substance.

ぎてもむだとなる。 The viscoelastic substance to be kneaded with the water-soluble polymeric substance aqueous solution is a water-insoluble or lipophilic substance that exhibits high viscoelasticity within a certain temperature range. Examples include tars or pitches, petroleum asphalt, petroleum distillation residue oil, wax, atactic polypropylene, atactic polyethylene, polyvinyl acetate, and ethylene-vinyl acetate copolymer. In the present invention, high viscoelasticity refers to a material that exhibits sufficient stringiness when shearing force is applied.
The amount of the viscoelastic substance to be used is sufficient as long as it can be sufficiently kneaded with the polymeric substance in the aqueous solution, and is usually about 1/5 times or more by weight, preferably about 1/2 to 2 times the weight of the aqueous solution. If the amount of viscoelastic substance used is too small, the polymeric substance cannot be effectively separated, and if the amount used is too large, it will be wasteful.

The kneading temperature may be within a range where the viscoelastic substance exhibits high viscoelasticity, and is usually room temperature. The kneading time can be determined by measuring the concentration of the polymer substance in the aqueous solution, but it is usually about 1
~30 minutes.
