The method comprises (1) discharging organic waste water into an anaerobic acidification treatment tank and carrying out preliminary pretreatment for 18 to 24 hours, (2) after the pretreatment, discharging the waste water into a photosynthetic bacterium (PSB) treatment tank and carrying out treatment for 10-15d, (3) carrying out reflux on the waste water discharged by the PSB tank according to a reflux ratio of 30-60%, (4) discharging the remaining reflux waste water discharged by the PSB tank into a sedimentation tank andcarrying out treatment for 12-24h, (5) introducing the waste water in the sedimentation tank into a Lemna aequinoctialis treatment tank and carrying out secondary treatment for 10-20d, (6) periodically feeding fresh bacteria into the PSB treatment tank during the treatment, and (7) periodically recovering and reusing the sludge and Lemna aequinoctialis in treatment. The method is simple and environmentally friendly, is low in cost and has high efficiency. The removal rates of BOD, ammonia nitrogen and total phosphorus are 90% or more.
