PURPOSE: Provided is an industrial wastewater reclamation system for preventing water pollution and stably obtaining water resource by using an air flotation process, a hollow fiber membrane process and an advanced oxidation process. CONSTITUTION: The system comprises a water tank(10) for storing domestic sewage and process water, a filter(20) for removing deleterious particles and suspended solids on sewage water using a screen, a flow equalization basin(30) for adjusting flow rate of the sewage water and load of pollutants in the sewage water, an air flotation separation basin(40) for generating bubbles using a mixer rotating at high speed and floating coagulated matter with the bubbles, thereby rapidly and effectively separating coagulated matter, a UV sterilizing device(50) for finally purifying and sterilizing the water by decomposing remained organic material and non-degradable substances using an advanced oxidation process, a hollow fiber UF membrane(60) for filtrating the sterilized and purified water, a treated water tank(70) for storing treated water, a drain tank(80) for storing sewage and wastewater containing overflown water of each basin and sludge, and a filter press(90) for compressing, filtrating and solid/liquid separating the sewage and wastewater.
