Oil and fat-containing wastewater treatment method and treatment equipment

摘要

PPROBLEM TO BE SOLVED: To provide an efficient and clean treatment method for treating waste water containing a fat and oil content. PSOLUTION: The waste water containing the fat and oil content is supplied from an inflow pipe 3 to a treatment tank 1. The waste water in the treatment tank 1 is allowed to flow into an inside tank 13 located on the inner part of the tank 1 by overflow. The waste water in the inside tank 13 is pumped up by means of a submerged pump 15 located on an inner part of the inside tank 13, and at least one part of the waste water which is pumped up is allowed to flow down toward the waste water in the treatment tank 1. Then, the waste water in the treatment tank 1 is taken out of a discharge pipe 5. Thereby, the waste water containing the fat and oil content is treated. PCOPYRIGHT: (C)2005,JPO&NCIPI
