PURPOSE: A bad smell reduction waste water treatment facility and a method thereof are provided to process the bad smell gas without separate culture tub and bio-reaction, thereby more effectively and economically reducing the bad smell of waste water. CONSTITUTION: A bad smell reduction waste water processing facility(200) includes a sludge detention/bad smell reduction tub(250), a bio-filter(260), a primary precipitation tub(220), a biological reaction tub(230), a secondary precipitation tub(240). The reduction tub makes the sludge and bad smell gas to flow in and detentions the sludge and primarily processes the bad smell by using the microorganism. The bio filter secondarily processes the bad smell gas by using the microorganism. The primary precipitation tub performs the primary reaction about the preprocessed flown out water in a preprocessing tub(210). The biological reaction tub removes at least on among the organic compounds, nutrient salt, nitrogen and phosphorus of the flown out water of the primary tub. The secondary precipitation tub performs a secondary precipitation reaction about the flown out water of the biological reaction tub. The primary precipitation tub and a secondary precipitation tub transmits the occurred sludge and bad smell gas to the sludge detention/bad smell reduction tub. |
