WATER PURIFICATION SYSTEM HAVING ELECTRICAL DISCHARGING EQUIPMENT WITH FILTERING SYSTEM AND WATER PURIFICATION METHOD USING THEREOF

摘要

A system and a method for water treatment are provided to treat sewage and wastewater efficiently at a low cost, simultaneously make it not necessary to replace or maintain and manage a membrane frequently and enable a membrane with relatively large pores to be used by reducing membrane fouling to the maximum, and reduce the generation of sludge by reducing the consumption of a flocculant. A water treatment system comprises: front filtration equipment(10); a micro-bubble generating unit(20) installed in rear of the front filtration equipment; a gas injection unit(30) for supplying gas to the micro-bubble generating unit; a reaction tank(40) which is installed in rear of the micro-bubble generating unit, and on which a DBD(Dielectric Barrier Discharge) part is installed; a high voltage pulse power generator(50) connected to the reaction tank; and rear filtration equipment(60) installed on the reaction tank. The micro-bubble generating unit includes a filter housing(21), a gas inlet(22) formed on an outer portion of the filter housing, and a micro-filter disposed within the filter housing. The gas injection unit is a device for supplying gas at a predetermined pressure using a compressor, a venturi tube and the like to control the amount of gas supplied through a gas amount control valve(31).
