Abstract

The invention discloses an in-situ biological purification method of odorous gas, belonging to the field of purifying odorous gas by utilizing biological reaction in environmental engineering, in particular to a method for carrying out in-situ purification by utilizing the biological reaction in the diffusion process of odorous pollutants. In the method, a biological filter plate is manufactured by adopting ventilate and porous inert material as a carrier, and microorganisms adhere and grow on the surface and the holes of the carrier. The biological filter plate covers on the surface of an odorous gas smelling source; odorous matter in the gas passes through the biological filter plate in the manner of free diffusion and is removed after being in contact with the microorganisms. The in-situ biological deodorization method does not need a gas collecting system, which can simplify operation and effectively reduces the energy consumption of treating the odorous gas.

Description

technical field [0001] The invention belongs to the field of using biological reaction to purify odorous gas in environmental engineering, and particularly relates to a method for using microorganisms to purify in situ during the diffusion process of odorous pollutants. Background technique [0002] During the process of industrial and agricultural production, sewage treatment, garbage treatment and composting, there will be odorous substances escaping and polluting the surrounding environment. Odor pollutants refer to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment. It stimulates olfactory cells through odorous groups such as sulfur and carboxyl. Generally, the concentration is low, the composition is complex, the monitoring is difficult, and the treatment is difficult. As a typical environmental hazard, malodorous substances have been recognized by countries all over the world. Many developed c...
