PURPOSE:To purify waste water at high degrees with a device of a small size by areating primarily or secondary treated water by addition of an oxidation assistant or an oxidizing agent or feeding air, oxygen or ozone alone or a gaseous mixture under pressure. CONSTITUTION:The waste liquid subjected to pretreatments is fed through an intake port 1 for waste water into a purifying tank 2, where the liquid is mixed with an oxidizing agent or oxidizing assistant 3 such as chlorine, hydrogen peroxide or the like. Air, oxygen or ozone is forced under pressure from an air compressor through a sucking and receiving port 4 to make amt. of dissolved oxygen 100% and is blown through diffusion pipes 7 for areation into the tank 2. UV rays are irradiated from a UV lamp 9 projected into the tank 2 and the laser generated from a UV laser generator 10 is irradiated through laser angle changing lenses 11, 12 into the waste liquid in the tank 2 through the laser transmission window 14 provided to the top cover 13 of the tank 2. |
