<p>PURPOSE:To save the cost of equipment and the consumption of electric power by aerating waste water introduced into a regulation tank while forcing the water into a settling tank. CONSTITUTION:Waste water is introduced into a regulation tank 1 and forcibly sent by an aeration water passage 3 into a settling tank 2 provided on the downstream side of the regulation tank 1 while being aerated. Consequently the efficiency of the waste water treatment can be increased and the equipment of the waste water treatment can be reduced, since an aeration tank, an oxidation vessel, a blowing device, etc., can be dispensed with. Accordingly, the cost of equipment can be reduced and the consumption of electric power can be saved.</p> |
