Method for reducing the polymer content of effluent during the drainage of polymer/water mixtures |
摘要 |
The invention relates to a method for reducing the polymer content in the wastewater from dewatering of two-phase liquid mixtures comprising a thermoplastic plastic melt and an aqueous phase by coagulating the plastic melt and pressing the water out of the melt cake in an extruder system, characterized in that superheated steam with a temperature of at least 280° C. is injected immediately after introduction of the two-phase liquid mixture into the extruder system.
