WATER PURIFICATION APPARATUS AND METHODS USING HYBRID PROCESS OF ADVANCED OXIDATION PROCESS AND MICROFILTRATION MEMBRANE PROCESS

摘要

An apparatus and a method for water purification using a hybrid process of an advanced oxidation process and a microfiltration membrane process are provided to minimize an installation area of a water purification system by performing a water purification process in a single hybrid process tank through advanced oxidation and membrane filtration and obtain highly purified drinking water by primarily decomposing contaminants in raw water and secondly removing residual harmful substances. An apparatus for water purification by a hybrid process of an advanced oxidation process and a microfiltration membrane process comprises: a raw water storage tank(10); a raw water inflow pipe(20) for flowing raw water stored in the raw water storage tank into the hybrid process tank through a pump(25); a hybrid process tank(30) having an advanced oxidation equipment(32) which is a UV-O3 quartz tube lamp and a microfiltration membrane equipment(34) therein; a blower(40) for injecting air into the hybrid process tank; at least one diffuser(36) connected to the blower and installed on the bottom of the hybrid process tank; a treated water discharge pipe(50) connected to the microfiltration membrane equipment and a treated water storage tank(60); a suction pump(55) installed on the treated water discharge pipe; a hydrogen peroxide diluent supply equipment(42) for supplying a hydrogen peroxide diluent into the hybrid process tank; a pH probe(44) installed on an inner part of the hybrid process tank; and a temperature controller(46) installed on the hybrid process tank.
