摘要： 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.

摘要： Provided is a process for the environmental-friendly treatment of sulfate-containing wastewater. The acidic, sulfate-containing wastewater is treated in a sulfate reducing bioreactor with influent and effluent looped through to the cathode compartment of an electrochemical cell. The electrochemical cell stabilizes the pH in the bioreactor by the in-situ production of base in the cathode compartment. Additionally, hydrogen is produced which is used in the bioreactor as electron donor for the sulfate reduction. The middle compartment of the electrochemical cell contains a sulfide rich aqueous solution in which the extracted cations are displaced by protons from the anode compartment. This results in the acidification of the sulfide rich solution, which is beneficial for the extraction of sulfides as H2S. This H2S can be used for the precipitation of metals in the beginning of the process, forming another loop.

摘要： An iron containing bioreactor for treating explosive compounds and other organics in contaminated surface water is disclosed. The bioreactor can be located either on-ground or in-ground at a location across which contaminated surface water flows. In one configuration the reactor is made up of (i) indigenous microbes, (ii) acetate, (iii) a low density iron-containing bed, and contains anaerobic zones in at least one portion of the flowpath. The reactor reduces the concentration of explosive compounds to below 10 ppb and also maintains this explosive compound reduction level for a period of at least one year without replenishing the microbes or iron.

摘要： The disclosure relates to a staggered electrode bio-electro-Fenton groundwater circulation well system, including a groundwater circulation well, a water pumping and injecting assembly and an in-well bio-electro-Fenton assembly. The water pumping and injecting assembly is configured to realize water pumping and injection between different screening sections of the groundwater circulation well. The bio-electro-Fenton assembly arranged in a first screening section of the groundwater circulation well includes at least one electrode device. A cathode and an anode of the electrode device form a spatially staggered arrangement according to different distribution areas. According to the disclosure, the spatially staggered arrangement of the cathode and the anode, the influence of oxygen on an anaerobic environment of an anode chamber in the electrode device is greatly reduced while ensuring the cathode takes oxygen as an electron acceptor, and the constructed bio-electro-Fenton system can accelerate the decomposition of organic pollutants in the groundwater circulation well.

摘要： Provided is a biochar-anaerobic membrane biological treatment system and process. The system mainly includes a reaction tank, a membrane module, a macroporous gas distribution device, low-temperature pyrolysis biochar. The application of the process to sewage treatment shows that: under the conditions that the hydraulic retention time is 3.2-7.2 h, the membrane flux is 12.0-17.8 L/m2/h, and the sludge concentration of 7.2-15.6 g/L, multiple objectives of promoting organic micropollutants (OMPs) biotransformation, accelerating methane production and strengthening membrane fouling control were achieved. The system improved OMPs removal efficiency by more than 20%, decreased membrane fouling rate by 50%, and reaching an organic matter removal efficiency of more than 86% at low temperature. The system and process solve the problems of poor OMPs removal efficiency, serious membrane fouling, and low methane yield at low temperature in the anaerobic membrane biological treatment system.
