摘要： The present disclosure discloses a method for screening bacteria capable of tolerating and degrading ethylene oxide, comprising: preliminary screening, purification, ethylene oxide tolerance acclimatization, and ethylene oxide degradation acclimatization. The methods for screening and acclimatization provided by the present application is simple to operate, and the ability of the acclimatized strains to degrade ethylene oxide is significantly improved. Therefore, a series of ethylene oxide-degrading strains capable of tolerating and degrading ethylene oxide may be obtained, which have excellent treatment performance and is safe, environmentally friendly, and is of great significance for decontamination treatment of ethylene oxide.

摘要： The present disclosure provides a gas liquefaction separator, a gas liquefaction recovery system, and a method for separating and recovering ethylene oxide. The gas liquefaction separator includes a housing, a blocking plate, a gas baffle, and a liquid collector, the latter three being located inside the housing. The liquid collector—an outer edge of which is connected to an inner wall of the housing—is located below the gas baffle, which is located below the blocking plate. The liquid collector includes a first flow guide surface, on a bottom portion of which is disposed a first hole. The gas baffle—an upper surface of which forms a second flow guide surface and an outer edge of which has a protrusion(s)—is connected to the first flow guide surface through the protrusion(s), thereby forming a second hole between the outer edge of the gas baffle and the first flow guide surface.

摘要： The present disclosure discloses a device, system, and method for treating an ethylene oxide waste gas. The system includes a first pressure swing adsorption tower, a first thermostatic assembly, a gas storage tank, a first branch pipe, and a second branch pipe. The first pressure swing adsorption tower comprises a first accommodating chamber which accommodates an adsorption material. A first vent port and a first exhaust port are in communication with the first accommodating chamber. The first pressure swing adsorption tower is partially disposed in the first thermostatic assembly. The gas storage tank comprises a gas inlet/outlet port. The first branch pipe and the second branch pipe are in communication with the first vent port. The first branch pipe couples the first vent port with the gas inlet/outlet port and the second branch pipe introduces an ethylene oxide waste gas into the first pressure swing adsorption tower.

摘要： The present disclosure provides a microbiological treatment system including a hydration system and microbiological degradation systems. The hydration system may include a gas-liquid mixing chamber, a gas inlet, a gas outlet, a liquid inlet, and a liquid outlet, the latter four being fluidly coupled to the chamber. The gas inlet is configured to introduce an ethylene oxide exhaust gas into the chamber to mix with an aqueous solution to form an ethylene oxide exhaust liquor. The liquid outlet is configured to discharge the ethylene oxide exhaust liquor. Each microbiological degradation system may include a degradation chamber containing degradation bacteria including one of anaerobic bacteria, facultative bacteria, or aerobic bacteria. The degradation chambers of the microbiological degradation systems may be in fluid communication sequentially in a predetermined degradation sequence, with the most upstream in the degradation sequence having a liquid inlet in fluid communication with the liquid outlet.
