METHOD FOR DEODORIZING NIGHT SOIL SEWAGE TREATING APPARATUS

PURPOSE:To decompose odorous components in a rancidity-contg. gas into odorless nitrogen, sulfur, etc. by introducing a rancidity-contg. gas generated from a night soil receiving tank, a storage tank, etc. into the reaction vessel of the night soil treating apparatus, and bringing the gas into conta...

Zusammenfassung:	PURPOSE:To decompose odorous components in a rancidity-contg. gas into odorless nitrogen, sulfur, etc. by introducing a rancidity-contg. gas generated from a night soil receiving tank, a storage tank, etc. into the reaction vessel of the night soil treating apparatus, and bringing the gas into contact with a liq. mixture of powdery activated carbon and activated sludge. CONSTITUTION:Night soil sewage which is not diluted is biologically oxidized, nitrated, and denitrified by the addition of powdery activated carbon in a night soil sewage treating apparatus. A rancidity-contg. gas G generated from a night siol receiving tank 1, a storage tank 3, etc. is introduced into the reaction vessel 4 of the night soil sewage treating apparatus, and brought into contact with a liq. mixture of powdery activated carbon and activated sludge to decom pose odorous components in the rancidity-contg. gas into odorless nitrogen and sulfur. In the deodorizing method, the operating cost is reduced, the mainte nance and control of the operation are facilitated and further the cost of equip ment can be saved.
