WATER TREATMENT SYSTEM OF SILICON WASTEWATER AND METHOD OF THE SAME

摘要

PURPOSE: A water treatment system for silicon wastewater and a method for the same are provided to suppress the generation of water pollution due to silicon wastewater by removing foreign materials such as silicon, carbon, and silica from silicon wastewater. CONSTITUTION: A water treatment system for silicon wastewater comprises a water treatment bath (10), an immersed type separating membrane (30), a produced water storing bath (50), and a concentrated water pump (P3). The water treatment bath receives silicon wastewater generated from a semiconductor process which is supplied from a wastewater storage tank. The immersed type separating membrane is immersed in the wastewater of the water treatment bath and removes foreign materials from the wastewater. The produced water storing bath stores water which is produced by removing foreign materials from the wastewater through the separating membrane. The concentrated water pump discharges concentrated water in which solid materials from the water treatment bath are dispersed.
