Abstract

The invention discloses a method for dealing with foul smell through atomization plasma oxidation-biomass adsorption, belonging to the field of purification technology for removing foul gases. The method adopts an atomization plasma oxidation-biomass adsorption device and comprises the following steps of: (1) feeding: breaking the plant waste and performing microwave irradiation modification, humidifying and feeding into a biomass adsorption tower; (2) atomization low-temperature plasma oxidation: continuously pumping water into a low-temperature plasma reactor by a water pump, and atomizing immediately; and leading out foul gases from a pollution source by a fan to enter an atomization low-temperature plasma device; and (3) adsorption by the adsorption tower: enabling the gas after strong oxidation of the low-temperature plasma device to enter the biomass adsorption tower for absorption and adsorption to remove residual foul gases and oxidation byproducts in the incoming gas. The method disclosed by the invention combines the advantages of a low-temperature plasma and adsorption method in removing foul gases, and avoids the problem of byproduct secondary pollution caused by the low-temperature plasma and the problems of the adsorbent production and regeneration cost and secondary pollution.

Description

technical field [0001] The invention relates to a purification technology for removing malodorous gas, in particular to a method for treating odor by atomization plasma oxidation-biomass adsorption. Background technique [0002] As one of the seven major public hazards (odor pollution, air pollution, water pollution, soil pollution, noise pollution, vibration pollution, and ground pollution), stench is harmful to people's health and the peace and comfort of life. It mainly affects the human body through the respiratory system. Violations can easily lead to disorders of the digestive system, endocrine system and nervous system. Slight odor pollution can easily cause irritability, irritability, insomnia, inability to concentrate, and memory loss, thereby affecting the quality of work and life. High concentrations of sudden odor pollution can even cause pulmonary edema to suffocate and die instantly. The sources of malodorous substances are extremely wide. On the one hand, the...
