Abstract:
The present invention provides a method for reducing or controlling wastewater and pollutant from emulsion polymerization resin production, comprising the following steps: (1) optimizing an emulsion polymerization reactor to lengthen a cleaning interval of the reactor so as to reduce the volumes of reactor cleaning wastewater and pollutant discharge; (2) demulsifying latex filter cleaning wastewater and removing a latex material so as to reduce the volume of the pollutant discharge; (3) demulsifying the highly concentrated reactor cleaning wastewater, then performing flotation recovery; (4) mixing graft polymerization wastewater and 1,3-diene polymerization wastewater, then performing demulsification; (5) mixing the demulsified latex wastewater and condensation and drying wastewater, then performing a coagulation and dissolved air flotation treatment; and (6) implementing a biological treatment process on the effluent from the coagulation and dissolved air flotation treatment to remove an organic material, nitrogen and phosphorus. The method of the present invention has the characteristics of reducing pollutants at a source, increasing product yield, saving resources, using different treatment according to wastewater property, and lowering treatment cost.

Claim (Index 26):
