Gas-liquid plasma and bioreactor system and method for remediation of liquids and gases

A reactor system, comprising:

• a continuously-flowing non-thermal plasma reactor comprising at least one internal wall, at least one electrically-conductive inlet electrode at one end of the internal wall, and at least one electrically-conductive outlet electrode at an opposing end of the plasma reactor, the electrically-conductive inlet electrode being configured to inject a mixture comprising a liquid, a gas and at least one organic compound into the plasma reactor, the injecting of the liquid and gas generating a continuously flowing liquid film region on the internal wall, and a gas stream flowing along the flowing liquid film region, the injecting further propagating a plasma discharge channel pattern along the interface between the flowing liquid film region and the flowing gas stream inside the plasma reactor;
• propagating the plasma discharge along the flowing liquid film region from the at least one electrically-conductive inlet electrode to the at least one electrically-conductive outlet electrode at an opposing end of the continuously-flowing plasma reactor;
• a pulse forming network and power supply for supplying a voltage to cause electrical breakdown across the at least one electrically-conductive inlet electrode and the at least one electrically-conductive outlet electrode;
• the reactor dissociating at least a portion of the liquid at the interface with the plasma discharge to form a plurality of dissociation products, and producing hydroxyl radicals, hydrogen peroxide and nitrogen oxides from the plurality of dissociation products, and contacting the hydroxyl radicals with the organic compounds present in the flowing liquid film region and in the flowing gas stream to produce organic compound dissociation products, and flowing the liquid, gas, plasma, dissociation products, and organic compound dissociation products to the electrically conductive outlet electrode;
• a bioreactor for receiving the dissociation products and organic compound dissociation products and converting the organic compound dissociation products to bioreactor products;
• a detector for detecting nitrogen oxide content in the bioreactor;
• a nitrogen oxide demand system for determining nitrogen oxide demand in the bioreactor;
• a feedback loop controller system for controlling the production of nitrogen oxides in the plasma reactor based upon the nitrogen oxide demand in the bioreactor and the nitrogen oxide content in the bioreactor.
