Abstract
PURPOSE: To treat the organic waste liquid readily and effeciently by subjecting the same to biological treatment without separating the precipitate being formed then subjecting the same to solid-liquid separation in the treating method of the organic waste liquid containing ammonia and phosphoric acids which is executed by adding magnesium compounds, phosphoric acid, etc.
CONSTITUTION: Magnesium compounds such as magnesium hydroxide and/or phosphoric acid (salts) are added to the organic waste liquid containing ammonia and phosphoric acid such as human excreta and the waste liquid is subjected to biological treatment (e.g., biological digestive denitrifying treatment) without separating the precipitate being formed. After the precipitate formation reaction and aging of ammonium magnesium phosphate by the use of long stagnation time in the digestive denitrifying tank, the floc is subjected to solid-liquid separation in the final sedimentation basin and flotation plant and the excess sludge is dehydrated by a dehydrator. The dehydrated and separated liquid is recycled into the digestive denitrifying tank as defoaming water.
