A method of treating sludge and a method of treating organic waste water comprising the same

摘要

A novel method for treating organic waste water is provided, which is capable of separating and recovering phosphorous components in a liquid or solid form. According to the method of the present invention, reuse of phosphorous components can be facilitated, while the content of phosphorous components contained in a large quantity of a primary treated liquid can be reduced. A method of treating sludge or organic waste water is provided comprising the step of heating the sludge at 60°C to 90°C for 10 min. to 120 min, to release the phosphorous components from the sludge to a liquid phase.
