Treatment device of sludge-containing small-molecule volatile organic gas

Abstract

The invention belongs to the sludge-containing small-molecule technical field and discloses a treatment device of sludge-containing small-molecule volatile organic gas. The device comprises a reactiontower body, a filler absorption structure, an aeration structure, a biological bacterium suspending liquid bin, a circulating pump, a spray structure and a rotational flow sub-separator; the filler absorption structure is arranged in the reaction tower body and is internally provided with a biological absorption material; the aeration structure is arranged below the filler adsorption structure and connected with an air inlet pipeline; the biological bacterium suspending liquid bin is arranged at the bottom end of the reaction tower body; a liquid inlet of the circulating pump is arranged in the biological bacterium suspending liquid bin, an output end of the circulating pump is respectively communicated with the spray structure through a spray pipeline so as to pump biological bacterium suspending liquid to the spray structure and spray downwards from a position which is above the filler adsorption structure; the rotational flow sub-separator is arranged at a lower part of the reaction tower body and positioned below the aeration structure and at an upper part of the biological bacterium suspending liquid bin, thereby enabling falling mixed liquid to be subjected to solid-liquid separation.

Description

technical field [0001] The invention relates to the technical field of small-molecule treatment of sludge, in particular to a treatment device for small-molecule volatile organic gas containing sludge. Background technique [0002] Sewage treatment in petroleum processing will produce a certain amount of wastewater treatment sludge. Sewage sludge is solid waste produced in the process of sewage treatment in sewage treatment plants, and it is also one of the problems faced by modern sewage treatment. If it is not handled properly, it will cause secondary pollution of sludge and "white sewage treatment" . Hydrolysis and carbonization of excess sludge, as the main sludge reduction and stabilization treatment process, has the advantages of reducing sludge volume, killing pathogenic microorganisms, improving sludge performance, and producing small molecular organic compounds, so it has always attracted the attention of researchers. Sludge treatment can destroy the particle comp...
