Integrated sewage treatment device

The utility model discloses an integrated sewage treatment device. The integrated sewage treatment device comprises an adjustment tank, an anaerobic tank, an aerobiotic tank, a sedimentation tank, a grating tank and a disinfection tank, wherein a vertical partition is arranged in the adjustment tank; a water flow channel is formed in the vertical partition; the grating tank is arranged at the upper left part in the first frame of the adjustment tank; the last section of the adjustment tank is communicated with the anaerobic tank; the anaerobic tank is communicated with the aerobiotic tank; the aerobiotic tank is communicated with the lower part of the sedimentation tank; a water outlet in the upper part of the sedimentation tank is communicated with the disinfection tank; horizontal suspended fillers are arranged in the middle of the aerobiotic tank; the suspended fillers are also arranged at the upper part of the sedimentation tank. According to the integrated sewage treatment device, the grating tank, the adjustment tank, the disinfection tank, a biochemical treatment part and a sedimentation part are integrated together, and the construction cycle and the land utilization area are greatly reduced. A biochemical tank comprises the anaerobic tank and the aerobiotic tank provided with the suspended fillers and does not comprise an anoxia tank and a sewage internal reflux system, so that the process is simple. A secondary sedimentation tank is replaced with a suspended filler filter tank, operation is simple, and effluent quality is good.
