Abstract:
1. A system for treating wastewater containing organic compounds, comprising: an anaerobic bioreactor capable of removing organic pollutants in wastewater through anaerobic treatment process, and said bioreactor containing methanogens; an aerobic bioreactor disposed rearwardly of said anaerobic bioreactor and capable of removing residual organic pollutants in the effluent of said anaerobic bioreactor through aerobic treatment process; a membrane separation reactor disposed rearwardly of said aerobic bioreactor and capable of separating solids from liquids in the effluent of said aerobic bioreactor; and a gas sparging device which is comprised in said membrane separation reactor for scouring membrane; wherein said aerobic bioreactor is further used as a stripper to strip carbon dioxide, where the pH value of wastewater is increased and crystals or solids suspended therein are inserted in the floc matrix of aerobes through bioflocculation to prevent scaling and fouling on the surface of said membrane.
