In one embodiment of the present invention, there is provided a moveable ventilation system comprising a supporting frame having at least one plenum, and at least one biofilter module mounted on the plenum for allowing air to flow through the biofilter module from an air inlet to an air outlet via a growth medium and a vegetation. The plenum is rotatably connected to the supporting frame.

Waste gas mixtures produced and used in industry may contain harmful sulphurous compounds. The present disclosure provides a method for treatment of gas mixtures contaminated with harmful sulphurous compounds by using microorganisms capable of degrading said harmful sulphurous compounds which involves controlling nitrate levels in the medium in which microbiological conversion of harmful sulphurous compounds takes place at high levels.

A process and apparatus for removing hydrogen sulphide from a gas is disclosed. The process comprises the steps of: providing a gas comprising hydrogen sulphide; supplying oxygen for the process if the gas does not comprise oxygen, or does not comprise sufficient oxygen for converting hydrogen sulphide to elementary sulphur; leading the mixture of gas and, if supplied, oxygen to a tank comprising i) a foam forming liquid, such as a scrubber liquid and ii) a foam layer made from said foam forming liquid on the top of the foam forming liquid where the hydrogen sulphide in the gas is oxidized to elementary sulphur to form a cleaned gas removed from hydrogen sulphide.

The present invention provides an exhaust gas purification system. In the exhaust gas purification system, a shower nozzle 20 disperses liquid toward exhaust gas 11 from an upper portion of the exhaust gas 11. The dispersed liquid is mixed with the exhaust gas 11 and thereafter, the liquid accumulates in a tank 30, and odor and oil content are dissolved by action of microorganism included in the liquid in the tank 30. The shower nozzle 20 is connected to an opening 24 horizontally provided in a nozzle pipe 23 connected to a liquid-supply pipe conduit 22. The exhaust gas purification system includes a nozzle 20N directed to a downward dispersing direction of the liquid. The nozzle 20N is placed in the nozzle pipe 23 such that a lower end 20L of the nozzle 20N is located higher than a bottom 25 of an inner wall of a pipe conduit of the nozzle pipe 23. According to this, exhaust gas including odor and oil content is purified.

A Kurthia gibsonii strain EO-06 with Deposit Number of CGMCC No. 18436, a Clostridium kogasensis strain EO-08 with Deposit Number of CGMCC No. 18438 and a Clostridium acidisoli strain EO-09 with Deposit Number of CGMCC No. 18439 are provided. The above strains can be used to treat pollution, for example, to treat industrial gas or wastewater containing ethylene oxide, which greatly improves the decontamination disposal capacity of ethylene oxide in industrial production. The present disclosure also provides a degradation agent for degrading ethylene oxide and a method for biodegrading ethylene oxide.

Provided is a carbon monoxide (CO) dehydrogenase with increased oxygen resistance and/or enzyme activity, specifically, a mutant CO dehydrogenase with increased oxygen resistance and/or enzyme activity by mutating amino acid residues. The CO dehydrogenase may detoxify toxic carbon monoxide at room temperature and pressure by easily oxidizing carbon monoxide and converting the same into carbon dioxide, and may effectively oxidize carbon monoxide even in gas including oxygen. Furthermore, since it is possible to remove carbon monoxide, which is emitted in large quantities in industries such as petrochemical and steel industries, cigarette burning, household cooking, various boilers, and combustion, through cigarette filters, air purifiers, intake filters in household cooking equipment, gas boilers, etc. the CO dehydrogenase may be utilized in various ways.
