    摘要: A method for the generation of a supply of ozone containing process gas exhibiting high effective ozone content basically involves the steps of (a) providing a stream of an oxygen containing feed gas having a temperature not greater than about 50.degree. C. and an absolute pressure between about 1 and 3 bar, (b) subjecting the stream of feed gas to an electric discharge that transforms some of its oxygen content into ozone to produce a stream of ozone containing gas, and (c) compressing the ozone containing gas with simultaneous cooling thereof to produce a stream of ozone containing process gas having a temperature not greater than about the temperature of the feed gas, an absolute pressure greater than 3 bar and an absolute ozone partial pressure of at least 0.2 bar. Various systems for carrying out such methods are disclosed.

    摘要: Process for recovering and reusing effluent gas from an ozonization reactor in a plant for treating effluent, especially sewage, which includes a biological reactor, a clarifier and an ozonization reactor. The effluent gas from the ozonization reactor is brought, as a cocurrent, into contact with a stream of water containing compounds that can be oxidized by the ozone, so that the residual ozone is removed and efficiently consumed. The effluent gas thus stripped of the residual ozone is then, optionally, pressurized using a fluid taken from the plant so as to produce a gas/liquid mixture. The gas liquid mixture is converted into an emulsion of fine bubbles, and the emulsion is introduced into the biological reactor, preferably near the bottom of the latter.
