Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；
Fig. 2 is the operation principle schematic diagram of the utility model.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
Embodiment:
Referring to Fig.1, A described in the present embodiment2O process integration sewage-treatment plant, including shell 14, the shell 14
Anaerobic Treatment workspace, anoxic treatment workspace and Aerobic Process for Treatment workspace are inside disposed with from top to bottom, at the anaerobism
Manage and be equipped with lower clapboard 5 between workspace and anoxic treatment workspace, the anoxic treatment workspace and Aerobic Process for Treatment workspace it
Between be equipped with upper spacer 8.The middle part of the shell 14 position corresponding with anoxic treatment workspace is equipped with observation panel 7.The shell
Sludge pipe 1 is installed on the lower end outer wall of body 14.
The bottom of the Anaerobic Treatment workspace is equipped with the water distribution supervisor 2 being connected with water inlet pipe, and top is equipped with gas collecting tube
4, the lower section of the gas collecting tube 4 is equipped with three phase separator 3；The bottom of the anoxic treatment workspace is equipped with nitrification liquid return pipe
16；High efficiency packing 11 is equipped in the Aerobic Process for Treatment workspace, the lower section of the high efficiency packing 11 is equipped with aerating system 9, efficiently
The top of filler 11 is equipped with water outlet water distribution system 12, and the water outlet water distribution system 12 is connected with outlet pipe 13；The Aerobic Process for Treatment
The corresponding shell 14 in workspace is equipped with nitrification liquid discharge pipe 15, between the nitrification liquid discharge pipe 15 and nitrification liquid return pipe 16
It is connected with reflux connecting tube 10, the position that the reflux connecting tube 10 connects with nitrification liquid return pipe 16 is equipped with nitrification liquid reflux
