METHOD AND APPARATUS FOR PURIFYING WASTE WATER

摘要

The present invention allows obtainment of filtered water having a superior water quality while requiring a short time for removing a plug, by disclosing a method for purifying waste water comprising: a plug formation step of forming the plug by inserting a material for forming a plug in waste water and mixing same in a mixing tub (100); a cyclone separation step of separating the waste water comprising the plug into waste water including a high-density plug and waste water including a low-density plug by means of a hydro cyclone (200); and a rising separation step of separating the waste water comprising the low-density plug into the low-density plug and filtered water by means of a rising separation tub (300).
