<p>PURPOSE: To reduce the use quantity of a flocculant to be used for flocculation treatment of solids following an aeration treatment by performing the aeration treatment. CONSTITUTION: In this waste water treatment in which the flocculant is added to the waste water containing solids dispersed in a colloid form, and the solids is flocculated and removed and then the waste water is treated by an activated sludge treatment, the waste water to be treated is subjected to the aeration treatment using the air with activated oxygen molecules activates by magnetic energy, before the solids are removed by adding the flocculant.</p> |
