The invention discloses an integrated waste water innocent treatment device which comprises a treatment bin (1). The treatment bin (1) is separated into an upper layer and a lower layer, the lower layer is separated into a
water storage bin (2) and a sterilization bin (3), the
water storage bin (2) and the sterilization bin (3) are abreast, and the upper layer is separated into an adjusting bin (4), a
biochemistry bin (5) and a
sedimentation bin (6), wherein the adjusting bin (4), the
biochemistry bin (5) and the
sedimentation bin (6) are abreast. A gas pump (7) and a water pump (8) are fixed to the upper portion of the treatment bin (1), the upper portion of the adjusting bin (4) is communicated with the
biochemistry bin (5), the biochemistry bin (5) is communicated with the
sedimentation bin (6) through a
siphon (9), and an opening, located on the biochemistry bin (5) side, of the
siphon (9) is formed in the bottom of the biochemistry bin (5). The sedimentation bin (6) is connected with the lower
water storage bin (2) through a communicating
pipe (10), and the water storage bin (2) is connected with the sterilization bin (3) through a second communicating
pipe (11). The adjusting bin (4) and the sterilization bin (3) are connected with a water inlet
pipe (12) and a water outlet pipe (13) respectively. The integrated waste water innocent treatment device is compact and simple in structure, few in external supporting facilities, high in
safe operation rate, low in operation cost and automatic and continuous in operation.
