Combined waste water and gas treatment system for efficiently decarbonizing and removing nitrogen

A combined waste water and gas treatment system for efficiently decarbonizing and removing nitrogen, the system comprising:

• a water feeding pump;
• a carbon capture device;
• an intermediate water tank;
• and
• an anaerobic ammonium oxidation reactor connected in sequence through pipelines;
• wherein the carbon capture device is of a fully enclosed structure and comprises an anode chamber fluidly communicated with the water feeding pump through a water inlet pipe, and a cathode chamber fluidly communicated with the intermediate water tank through a first water outlet pipe;
• the anode chamber is separated from the cathode chamber through an ion exchange resin layer;
• an anode plate electrically connected to a positive electrode of a power supply is arranged in the anode chamber;
• a cathode plate electrically connected to a negative electrode of the power supply is arranged in the cathode chamber;
• a gas inlet pipe is further arranged at a bottom of the cathode chamber;
• an air compressor is connected with the gas inlet pipe;
• a gas outlet pipe is arranged at a top of the carbon capture device;
• a water outlet in a bottom of the intermediate water tank is fluidly communicated with a bottom end of the anaerobic ammonium oxidation reactor through a second water inlet pipe;
• the gas outlet pipe is fluidly communicated with the second water inlet pipe;
• the anaerobic ammonium oxidation reactor is an upflow anaerobic sludge bed;
• a three-phase separator is arranged at a top end of the anaerobic ammonium oxidation reactor.
