Method and apparatus for treating organic waste water and organic sludge |
| abstract |
Provided is a technique which makes it possible to recover fine MAP particles which cannot be separated by a physical means such as a liquid cyclone so as to significantly improve a phosphorus recovery rate from sludge. Proposed is a method for treating organic waste water or organic sludge comprising a phosphorus separation step in which by using MAP particles contained in anaerobically treated sludge obtained by anaerobically treating organic waste water or organic sludge as seed crystals, the MAP particles are grown by crystallizing, as MAP, a phosphorus component dissolved in solid-liquid separation water returned from the subsequent sludge amount reduction step, followed by separation into the grown MAP particles and MAP-depleted sludge, a pH adjustment step in which the pH of the MAP-depleted sludge obtained by the separation in the phosphorus separation step is decreased to dissolve the MAP particles remaining in the MAP-depleted sludge, thereby obtaining pH-adjusted sludge, and a sludge amount reduction step in which dehydrated cake is obtained by condensing and dehydrating the pH-adjusted sludge and a part or the whole of solid-liquid separation water obtained by the condensation and dehydration is returned to the phosphorus separation step. |
