Abstract: A method for advanced nitrogen and phosphorus removal of domestic sewage based on DEAMOX in AOAO process with sludge double-reflux is disclosed. The method comprises allowing domestic sewage and returned sludge of the secondary sedimentation tank (3) to enter the anaerobic zone (2.1) of the AOAO reactor (2), firstly performing partial denitrification by the denitrifying bacteria, reducing nitrate-nitrogen in the returned sludge to nitrite-nitrogen, then converting ammonia-nitrogen and nitrite-nitrogen into nitrogen by anammox bacteria, and phosphate accumulating bacteria and denitrifying phosphate accumulating organisms performing anaerobic phosphate release and storing internal carbon source; then allowing part of the mixed liquid to enter the intermediate aerobic zone (2.2) of the AOAO bioreactor (2) to carry out phosphate uptake and nitrification reaction, allowing another part of the mixed liquid to enter the anoxic zone (2.3) of the AOAO bioreactor (2), at same time allowing all the mixed liquid of the intermediate aerobic zone (2.2) and part of returned sludge of the secondary sedimentation tank (3) to enter the anoxic zone (2.3), using the internal carbon source stored in the anaerobic compartment and the internal carbon source in the returned sludge to carry out partial denitrification, anammox, denitrifying dephosphatation, and then allowing the mixed liquid to enter the post aerobic zone (2.4) and subsequently enter the secondary sedimentation tank (3) for mud-water separation. An apparatus for advanced nitrogen and phosphorus removal of domestic sewage based on DEAMOX in AOAO process with sludge double-reflux is also disclosed.

Abstract: Methane is generated from animal waste by anaerobic digestion using bacteria. A screen separator removes suspended solids greater in size than a predetermined size ranging from about 50 µ to about 150 µ. An electrocoagulation unit electrochemically hydrolyses the waste, causing particles to settle out. A dissolved carbon air flotation has a CO2 bubbler for separating large particles from small particles by flotation. An anaerobic digester produces biogas. The digester has a biocurtain for growing the bacteria and a heat exchanger for heating the bacteria. The biocurtain surface is convoluted to retain the bacteria. A membrane module removes CO2. A knock out pot for removes droplets of water. A scrubber removes water vapor, particulates, and contaminant gas. A compressor boosts pressure. A gas chromatograph monitors the biogas composition. A flare skid lowers excess pressure for safety. Biogas is injected into a local pipeline system. A process control is used for controlling the anaerobic waste digestion system.

Abstract: An induced sludge bed anaerobic reactor includes a vessel in which a septum is positioned to maintain solids in wastewater being treated toward a lower portion of the reactor. The septum is configured to prevent or minimize rising bacteria from exiting the vessel and to minimize clogging of the vessel. A first example septum is disclosed that is based on a linear vane design. A second example septum is disclosed that is based on a concentric vane design. A third example septum is disclosed that is based on a radial vane design that may include one or more sections. Further, septums may be layered one atop another to further minimize rising bacteria from exiting the vessel and to further minimize clogging of the vessel. Finally, a septum is attached to the inside of the vessel so as to allow it to move allowing any clogging waste floating under the septum to exit the vessel.
