Abstract: The present disclosure relates to the technical field of microbial electrochemical technology, in particular to a graphene-magnetite conductive skeleton electrode, a preparation method and application thereof, and a method for treating petrochemical wastewater. In the present disclosure, the surface roughness of the graphite rod electrode can be increased by the conductive skeleton modified on the surface of the graphite rod electrode, which is beneficial to the enrichment of microorganisms. The increase in the load of microorganisms will mean the amount of electroactive microorganisms will also increase, which will further improve the electron transfer ability, and because the material of the modified layer is a conductive material, it is also more conducive to the transfer of electrons; at the same time, the conductive skeleton modified on the surface of graphite rod electrode can also further enhance the transmission distance of electrons because of the skeleton constructed.

Abstract: The present invention provides an oxidative decontamination reagent for removal of the dense radioactive oxide layer on a metal surface, which comprises an oxidizing agent, a metal ion, and an inorganic acid. The oxidative decontamination reagent of the present invention is characteristically prepared by adding a metal ion to the conventional oxidative decontamination reagent containing an oxidizing agent and an inorganic acid. When the oxidative decontamination reagent of the present invention is used, electric potential of the metal parts of the primary system of the nuclear power plant can be regulated as passive potential owing to the added metal ion during the oxidative decontamination of the primary metal part of the nuclear power plant. Therefore, by maintaining electric potential of the metal part as passive potential, local corrosion can be inhibited and at the same time secondary waste can be significantly reduced.

Abstract: A method of preparing an oxidant stream comprising: burning a combustion mixture comprising (a) one or more fuel composition and (b) oxidant comprising a first oxygen content of about 10 mole % or more and a first carbon dioxide (CO2) gas content of about 68 mole % or more on a dry basis, the burning producing a flue gas comprising CO2 gas, water vapor, and unreacted oxygen; separating from the flue gas a recycle stream; mixing at least a portion of the recycle stream having a first pressure with a sufficient amount of an oxygen stream having a second pressure which is sufficiently higher than the first pressure to entrain at least a portion of the recycle stream in the oxidant stream and to produce the oxidant stream having a second oxygen content of 10 mole % or more and a second CO2 gas content of about 68 mole % or more on a dry basis.
