WASTEWATER TREATMENT DEVICE AND METHOD BY MULTI ANAEROBIC AND AEROBIC METHOD USING YAKURUT EMPTY BOTTLE

摘要

The present invention is an anaerobic filtration tank for decomposing sedimentation solution and removing nitrogen by an anaerobic microorganism attached to a sedimentation separation chamber (3) and an anaerobic microorganism attached to the plate-like filter (9). 4) and the aeration tank (5) in which multiple waste aerobic bottles (12a) are arranged in multiple columns to form multiple anaerobic aerobic conditions, and a spherical filter (21) having a biofilm for filtering the treated water precipitated in the final settling tank (6). The present invention relates to a wastewater treatment system and method using a multiple anaerobic exhalation method using waste yakult vaccum bottles continuously installed according to the treatment procedure.;According to the present invention, the biochemical oxygen demand and the suspended solids of the final treatment water were 10,15 mg / L, respectively, and showed better characteristics than the treatment water of the co-treatment plant. The total nitrogen and total phosphorus were 8.2, 5.3 mg / L, 89.5, A high removal efficiency of 56.7% was achieved. In addition, by using waste yogurt bottles as a main material, the production cost of the treatment apparatus was lowered and an appropriate means of recycling waste resources was provided.
