Combined processing device for malodorous gas and sewage

摘要

(57) [Abstract] [Purpose] The purpose of the present invention is to provide a new device that enables the rational and effective treatment of wastewater and malodorous gas at the same time by utilizing the wastewater treatment facility as a scavenger. An object of the present invention is to provide a combined treatment device for malodorous gas and sewage that does not require an alkaline agent for neutralization (pH adjustment) in the treatment. The present invention is, for example, an apparatus in which a packing layer 7 of granular material 6 is arranged on the upper side and a submerged filter bed 2 of granular filter medium 1 is arranged on the lower side with a gap 16 interposed therebetween. Clarified water 11 obtained by treating sewage in the submerged filter bed 2 is sprinkled from the upper part, and a malodorous gas is supplied to the packed bed 7 from the lower malodorous gas supply pipe 8 for deodorization. An apparatus for combined treatment of malodorous gas and sewage, characterized in that the sewage is made to flow from the gap between the sewage and the sewage, and oxygen-containing gas is supplied from the lower part to treat the sewage and the falling water of the sprinkling water.
