Abstract
PURPOSE: To facilitate night soil disposal at a high efficiency in a simplified operational management, by desiccating sludge from a decontamination vessel, mixing the obtained liquid with stock night soil, and biologically denitrifying the mixture.
CONSTITUTION: Sludge from a decontamination vessel is separated to a liquid and a cake by a desiccator 5. The separated liquid is reserved in a vessel 6. The liquid is nitrified in the first aeration vessel 7, mixed with stock night soil, and nitrified and denitrified in the second aeration vessel 8 where both of nitrifying and denitrifying bacteria are growing. In this process, a part of the untreated night soil is used as an organic source for denitrification of NH4-N contained in the separated liquid. Consequently, night soil or the like sewage can be easily disposed in a simplified operational management, regardless of the charge ratio of sludge from a decontamination vessel to untreated night soil.
