Abstract

The invention discloses a zero-emission treatment system and method of epoxy ethane. The method comprises the following steps: firstly, a chemical combination treatment is carried out on an epoxy ethane waste gas in a chemical combination device; the epoxy ethane waste gas generates a sulfonation reaction with a sulfonation reaction agent in the chemical combination device; the epoxy ethane is oxidized to generate carbon dioxide and ethylene glycol; the generated carbon dioxide and the residual epoxy ethane waste gas are discharged into a turbulence ball tower; the residual epoxy ethane waste gas is output to the turbulence ball tower by a gas-liquid pump and is fully mixed and dissolved in hot water pumped by the gas-liquid pump in the turbulence ball tower; then, the epoxy ethane waste gas dissolved in the wastewater is treated on the basis of an aeration tank, a sedimentation tank and a filter tank, and meanwhile, organic matters in the wastewater can be treated as well, wherein micro-biological degradation is mainly used for carrying out oxygenation degradation on the epoxy ethane waste gas dissolved in the water through microbial communities forming flocculating constituents in the aeration tank; finally, CO2, H2O, NH3, SO42 and the like are generated and are discharged with the water, so that the epoxy ethane waste gas is treated.

Description

technical field [0001] The invention belongs to the technical field of ethylene oxide sterilization, and relates to an ethylene oxide zero-emission treatment system and method. Background technique [0002] Ethylene oxide, also known as ethylene oxide, is a colorless liquid at low temperature, with an aromatic ether smell, a boiling point of 10.8°C, and a density of 1.52; ethylene oxide is flammable and explosive, and its minimum burning concentration is 3%. Ethylene oxide gas has strong bactericidal power and wide bactericidal spectrum, and can kill various microorganisms including bacterial spores. It is a bactericidal agent. [0003] Ethylene oxide does not damage sterilized items and has strong penetrating power, so most items that are not suitable for sterilization by general methods can be sterilized and sterilized with ethylene oxide. For example, electronic instruments, optical instruments, medical equipment, books, documents, fur, cotton, chemical fiber, plastic pr...
