Method for treating sewage |
| abstract |
Realization of a treatment method of wastewater which can effectively suppress odor of hydrogen sulfide and methyl mercaptan generated from sludge produced in the treatment process of wastewater. A step of precipitating and separating the second sludge from the wastewater in the first settling basin 12, a step of separating the excess sludge by performing a biological treatment on the wastewater after the separation of the second sludge, the step of concentrating the second sludge, A step of mixing the second sludge and the excess sludge after concentration and a step of dewatering the mixed second sludge and excess sludge, wherein the first sludge precipitate is separated from the first sludge precipitate The nitrite is added to the second sludge and / or the surplus sludge in the step after the metal salt is added to the wastewater and the second sludge and the excess sludge are separated from the wastewater. |
