| titleOfInvention | Oil-containing wastewater treatment method |
| abstract | The present invention provides a polymer flocculant capable of improving the quality of treated water with superior flocculation performance than conventional polymer flocculants in the flocculation treatment of oil-containing wastewater. SOLUTION: A polyvinylamine water-soluble composition having a reduced viscosity at 25 ° C. in a 1 mol / L sodium chloride aqueous solution of 1.0 to 12.0 dL / g and an amination degree of 20 to 100 mol%. Polymer flocculant made of polymer. By adding the polymer flocculant to the oil-containing wastewater having an n-hexane extract amount of 100-10000 mg / L and an SS concentration of 200-3000 mg / L, high coagulation treatment performance is exhibited. As a result, a method for treating oil-containing wastewater that can separate the oil and improve the quality of the treated water. [Selection figure] None |
