Abstract:
1. A method for treating wastewater containing organic compounds, comprising the steps of: (a) feeding wastewater containing organic pollutants into an anaerobic bioreactor where the anaerobes therein decompose the organic pollutants in the wastewater; (b) feeding effluent of anaerobic bioreactor in step (a) into an aerobic bioreactor where the aerobes therein decompose the residual organic in wastewater and carbon dioxide dissolved in water is stripped through air stripping so that the pH value of water is increased, whereby the crystals of metal carbonate, struvite and inorganic solids are produced and inserted in the floc matrix of aerobes through bioflocculation; and (c) feeding effluent of aerobic bioreactor in step (b) into a membrane separation reaction where solids in the water are separated to obtain effluents free of organic pollutants.
