The present invention relates to systems and methods for removing and recovering precious metals, such as platinum-group metals (PGMs), including palladium, from wastewater and waste streams. The invention also relates to systems and methods for recycling the recovered precious metals for catalytic applications.
摘要:
A hybrid activated iron-biological treatment system and method for treating wastewater. The treatment system includes a combination of zero valent iron, ferrous iron, an iron oxide, and a denitrification microorganism. The present invention provides hybrid activated iron-biological systems and methods for treating a contaminated fluid to remove or reduce the concentration of the contaminant in the fluid. In one aspect, the invention provides a treatment system for removing or reducing the concentration of a contaminant in a fluid. In one embodiment, the system includes an activated iron (abiotic) component comprising a reactive solid comprising (a) zero-valent iron and one or more iron oxide minerals in contact therewith, and (b) ferrous iron, in combination with a biological (biotic) component comprising one or more denitrification microorganisms.

摘要:
Processes and compositions for removal nitrogen, and organic and inorganic contaminants from wastewater using Feammox bacterium are provided. The composition includes Feammox bacteria and at least one of soil, wastewater, or a carrier. The Feammox bacterium are capable of oxidizing ammonium coupled with reduction of Fe(lll) to Fe(ll) and a carrier. The system includes a reactor and a composition that includes a Feammox bacterium and at least one of soil, wastewater or a carrier. The process includes mixing the wastewater with Feammox bacterium. The process includes adding Feammox bacterium to the soil or groundwater system.
摘要:
An anaerobic electrochemical membrane bioreactor (AnEMBR) can include a vessel into which wastewater can be introduced, an anode electrode in the vessel suitable for supporting electrochemically active microorganisms (EAB, also can be referred to as anode reducing bacteria, exoelectrogens, or electricigens) that oxidize organic compounds in the wastewater, and a cathode membrane electrode in the vessel, which is configured to pass a treated liquid through the membrane while retaining the electrochemically active microorganisms and the hydrogenotrophic methanogens (for example, the key functional microbial communities, including EAB, methanogens and possible synergistic fermenters) in the vessel. The cathode membrane electrode can be suitable for catalyzing the hydrogen evolution reaction to generate hydro en.
