TREATMENT METHOD FOR EMULSION POLYMERIZATION-BASED POLYMER-CONTAINING WASTE LIQUID

摘要

PPROBLEM TO BE SOLVED: To provide a treatment method for emulsion polymerization-based polymer-containing waste liquid which can improve the collection efficiency of flocculation of emulsion polymerization based polymers by increasing the particle size of the flocculate and reduce the content of organic substances in the waste water to be discharged. PSOLUTION: In this treatment method for flocculating the emulsion polymerization based polymers and separating them from the emulsion polymerization based polymer-containing waste liquid, aluminum sulfate is added to the emulsion polymerization based polymer-containing waste liquid, a first polymer coagulant is added to the waste liquid to which the aluminum sulfate has been added, and a second polymer coagulant having an electric charge different from that of the first polymer coagulant is added to the waste liquid added with the first polymer coagulant.
