Title:
WATER TREATMENT INSTALLATION AND WATER TREATMENT METHOD
Document Type and Number:
Japanese Patent JP2021104489
Kind Code:
A
Abstract:
To provide a water treatment installation capable of further efficiently achieving the dominance of specific microbial groups.SOLUTION: A water treatment installation 10 includes a biological treatment tank 11 for biological treatment of organic wastewater by microorganisms, a solid-liquid separation tank 12 for solid-liquid separation of the organic wastewater treated in the biological treatment tank 11, and a dewatering mechanism 16 for dehydration treatment of the sludge separated in the solid-liquid separation tank 12. The water treatment installation has an air diffusing mechanism, a sludge conditioning tank 13 in which a part of the sludge separated in the solid-liquid separation tank 12 is introduced and conditioned, a reactor 14 filled with a biological treatment aid which makes a specific group of microorganisms dominant among the microorganisms, a sludge circulation path which circulates the sludge introduced in the sludge conditioning tank 13 through the reactor 14, and a sludge supply channel which exclusively supplies the sludge conditioned in the sludge conditioning tank 13 to the biological treatment tank 11.SELECTED DRAWING: Figure 1
