Title: Method for preventing generation of spoilage and malodor in drain tank for building
Inventor: ITO HAJIME
IPC: C02F1/00
Filed: 1987-01-22
Abstract: PURPOSE:To prevent the generation of suspended scum, by a method wherein the drain water in a tank is stirred under the supply of air and the suspended scum is sucked and ground in an aeration apparatus while the water level in the tank is controlled by the operation of a pump. CONSTITUTION:When a submerged pump 4 is driven, a stirring blade 5 is revolved and the drain water in a tank is stirred to generate negative pressure in the water at the leading end part of the blade 5. Air is blown in the drain water from the atmosphere from an air blow pipe 11 by said negative pressure and mixed with the stirred stream of the drain water in a draft tube to be pushed out in the forward direction of the draft tube. The air blow port the air blow pipe is inserted in the stirring blade and a large amount of air is blown in the drain water by utilizing the negative pressure in the max. degree to allow scum 8 to flow in the draft tube and said scum 8 is ground by the stirring blade. By this method, cleaning cost can be reduced.
