Device and process for treating odorous waste gas based on plasma technology in cooperation with biodegradation

Abstract

The invention relates to a device and a process for treating odorous waste gas based on a plasma technology in cooperation with biodegradation. The device comprises a low-temperature plasma waste gastreatment complete device; a collecting system is arranged at the upstream of the low-temperature plasma waste gas treatment complete device, an induced draft fan is arranged at the downstream of thelow-temperature plasma waste gas treatment complete device and is connected with a biological soil treatment system through a connecting pipeline, a discharge system is arranged at the downstream of the biological soil treatment system, and a de-fogging system is arranged between the low-temperature plasma waste gas treatment complete device and the collecting system; the low-temperature plasma generation adopts a double dielectric barrier generation technology; a gas collecting hood performs accurate collection on an odorous source, the control over air volume is realized by an adjusting valve, odorous waste gas is deeply treated by the biodegradation technology after being treated by the low-temperature plasma treatment technology, the treated odorous waste gas can be directly dischargedfrom a lawn above biological soil, and the standard requirements for unorganized discharge can be met.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment equipment, in particular to a device and process for controlling malodorous waste gas based on plasma technology for collaborative biodegradation. Background technique [0002] Now freshwater lakes have very high environmental requirements, and their water quality is closely related to the production and life of tens of millions of residents in the basin around the lake. It is an important water source for industrial and agricultural production and people's lives in the area along the lake. However, in recent years, due to the fertilizer residues from the farmland around the lake and domestic sewage and industrial wastewater from cities around the Chaohu Lake Basin flowing into the lake, the eutrophication of many large rivers and lakes has continued to intensify, leading to large-scale outbreaks of blue-green algae and greatly destroying freshwater. Ecology of the lake. In order to s...

Problems solved by technology

The lakeside is generally a scenic spot, and erecting a separate exhaust duct will greatly affect the appearance. A device and process with higher processing efficiency is needed to change the status quo and prevent odorous exhaust gas from directly entering the air, causing air pollution.
