Abstract

The invention relates to a waste gas purification plant with integration of plasma and a biological method. The waste gas purification plant comprises a purification tower, a circulating water pump and a regulating tank, waste gas in the purification tower sequentially flows through a plasma generator, a biological treatment device and a spray thrower, the spray thrower is connected with the circulating water pump, a water outlet of the regulating tank is connected with the circulating water pump, a water return port of the regulating tank is connected with the bottom of the purification tower, and culture fluid for culturing microorganisms is filled in the regulating tank. Toxic, harmful and odor pollutant is directly in prophase treatment by large quantities of active particles in the plasma, is converted into simple compounds, then continues to be degraded by the biological method and finally turns into nontoxic, harmless and odorless gas, secondary pollution is prevented, and harmful byproducts are effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a waste gas purification device which integrates two single processes of plasma and biological method. Background technique [0002] The main working principle of plasma treatment of exhaust gas is: using high-voltage power supply to establish a streamer discharge plasma field with reasonable distribution in the reactor. In the plasma field, the gas is locally ionized, producing a high concentration of ions O, O 3 , OH and other free radicals, these free radicals directly participate in the reaction as active factors, and crack macromolecular organic compounds into simple small molecular compounds. The plasma reactor is an efficient cracking and oxidation reactor. The molecular bonds of the odorous compounds in the exhaust gas are easier to be opened or oxidized. Its characteristic is that it is not limited to the treatment of certain organic and inorganic substanc...
