NOVELTY - Organic waste sewage and biogas pool integrated treatment device comprises a biogas pool and an organic waste sewage treatment pool surrounding the biogas pool, specifically, the biogas pool includes a feed inlet, an outlet and a biogas outlet that are communicated with a fermentation pool during fermentation; the capacity of the organic waste sewage treatment pool is designed according to a required organic waste sewage treatment amount and the days of treatment in a local environment; and organic waste sewage input pipes are arranged on the treatment pool in a day order.    USE - The device is useful for organic waste sewage and biogas pool integrated treatment (claimed).    ADVANTAGE - The device does not cause adverse consequences of a variety of the same degree of secondary pollution; does not have large number of processing; and does not have shortcomings of the fermentation of organic waste.    DETAILED DESCRIPTION - Organic waste sewage and biogas pool integrated treatment device comprises a biogas pool and an organic waste sewage treatment pool surrounding the biogas pool, specifically, the biogas pool includes a feed inlet, an outlet and a biogas outlet that are communicated with a fermentation pool during fermentation; the capacity of the organic waste sewage treatment pool is designed according to a required organic waste sewage treatment amount and the days of treatment in a local environment; organic waste sewage input pipes are arranged on the treatment pool in a day order; the height of the input pipes is equal to that of a biogas pool feed pipe; the lower part of the organic waste sewage treatment pool is provided with overflow pipes that are communicated with the inside of the biogas pool; the overflow pipe outlets going deep into the biogas pool are higher than the material level in the biogas pool; the overflow pipe inlets in the organic waste sewage treatment pool are lower than the overflow pipe outlets in the biogas pool; and the inner cavity of the organic waste sewage treatment pool is an annular overall structure surrounding the biogas pool or a separated structure arranged around the biogas pool.
