NOVELTY - A waste water containing phenol is treated by dipping sawdust to 5-20% sodium sulfite at 60-100 degrees C for 24-64 hours, regulating pH to 2-4, neutralizing with 10-30% sodium hydroxide solution, bathing, and drying; cultivating Alcaligenes faecalis, dipping sawdust to bacterium fluid at 25-35 degrees C with pH 6-8, aerating without waste water, fixing strain for 48-120 hours, and removing bacterium fluid to obtain Alcaligenes faecalis immobilized by sawdust; and feeding fresh culture solution, and activating for 12-72 hours.    USE - Method of treating waste water containing phenol (claimed).    ADVANTAGE - The method provides immobilized Alcaligenes faecalis that is easy to cultivate, where immobilization process is simple; treats waste water containing phenol with high concentration of 3000 mg/L; improves treatment efficiency, where Alcaligenes faecalis has perfect elasticity and strong tolerance to temperature and pH value; and has good catalysis degradation effect and stable degradation property, long half life, simple treatment process, low cost, mild condition, friendly environment, uneasy to drain bacterium, high microorganism concentration, fast degradation speed and high degradation efficiency, and no secondary pollution which can continuously degrade waste water containing phenol industrially.    DETAILED DESCRIPTION - Treatment of waste water containing phenol involves: (1) dipping 20-100 meshes sawdust to 5-20% sodium sulfite at 60-100 degrees C for 24-64 hours, regulating pH to 2-4, neutralizing with 10-30% sodium hydroxide solution, bathing, and drying; (2) cultivating Alcaligenes faecalis (JH 1013 CCTCC M208006), dipping sawdust to bacterium fluid at 25-35 degrees C with pH 6-8, aerating without waste water, fixing strain for 48-120 hours, and removing bacterium fluid to obtain Alcaligenes faecalis immobilized by sawdust; (3) feeding fresh culture solution, activating for 12-72 hours, bathing to remove residual culture solution, and feeding waste water containing phenol at 20-40 degrees C with pH 5-10; and (4) aerating and biologically treating, and sampling water to measure treatment effect.
