Biodegradation-based epoxy ethane waste gas treatment method and system

Abstract

The invention discloses a biodegradation-based epoxy ethane waste gas treatment method and system. According to the method and the system, epoxy ethane waste gas dissolved in wastewater is treated based on an aeration tank, a sedimentation tank and a filtering tank, and meanwhile, the treatment of organic matters in the wastewater is further realized; micro-biological degradation mainly comprises the following step of carrying out oxygenation degradation on the epoxy ethane waste gas dissolved in the water based on a microbial community generating flocculating constituents in the aeration tank; when the oxygenation degradation is carried out through the microbial community, aerobic biological treatment is carried out, the conversion of the organic matters including the epoxy ethane comprises the steps of carrying out assimilation synthesis and alienation decomposition on the organic matters by virtue of microorganisms under a sufficient oxygen condition, so as to finally generate CO2, H2O, NH3, SO2 and the like; as the CO2, the H2O, the NH3 and the SO2 are exhausted along with the water, the epoxy ethane waste gas treatment is realized.

Description

technical field [0001] The invention belongs to the technical field of ethylene oxide sterilization, and relates to a method and system for treating ethylene oxide waste gas based on biodegradation. 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, chem...

AI Technical Summary

Problems solved by technology

[0004] Due to the flammability, explosion and carcinogenicity of ethylene oxide, the control of ethylene oxide gas sterilization is still relatively difficult, especially the harmless treatment of ethylene oxide waste gas is a current problem

It should also be pointed out that the waste gas of the currently used ethylene oxide sterilization technology is basically discharged directly into the air without any treatment, so there are great environmental hazards and safety pressures, which need to be solved urgently. The problem
