Further, described filler plate layer structure is polypropylene material, and filler plate inner core is TPO material；Ceramic corrugated filler is a kind of Novel standardized packing, and the filler unit body that it is had same geometry by many forms；Due to the structure that pottery is unique, there is good hydrophilicity, the tiled serpentine passage of turbulence and air-flow that its surface can form very thin liquid film can promote air-flow but not stop that air-flow makes ceramic packing can be equal to mutually with metal packing, and it is corrosion-resistant, resistance to elevated temperatures metal packing cannot be compared；Surface texture has good wet performance, can make that liquid accelerates flowing, to make filler dispersed phase holdup be down to minimum, thus reduces overheated, polymerization and the chance of coking.
Further, described sloping plate deposition district is provided with mud mouth；Mud is discharged by mud mouth.
Further, being provided with sludge pump in described sloping plate deposition district, sludge pump connects with mud mouth.
Further, described cell body outer wall bottom is provided with sludge pipe, and sludge pipe connects with sludge pump；By sludge pump by the mud in sloping plate deposition district from mud mouth detach then by sludge pipe discharge process.
Further, described cell body bottom is provided with aeration tube, and cell body outer wall is provided with aerator, and aerator connects with aeration tube, and aeration tube is provided with aerating pore；By aerator, external air is forced in press-in aeration tube, then there is the air of certain blast by carrying out aeration operation in aerating pore entrance cell body, the diameter reducing air bubble can increase the contact area of gas-liquid two-phase, and then improve aeration efficiency, increase oxygen in water, also improve the organic speed of microbial decomposition.
Further；Described cell body bottom is provided with water inlet pipe, and cell body top is provided with outlet pipe；Water inlet pipe is arranged on cell body bottom so that water body flow direction is from bottom to up, reduces water body flow speed, adds biomembrane and waste water time, improves clean-up effect.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) biological contact oxidation process and activated sludge aeration method are combined by this device, add the biomembranous time of staying and hang modulus, improve the efficiency of purifying organic；
(2) this apparatus structure is compact, and floor space is little；
(3) single flow path that this device utilizes multiple field filler plate to be formed makes sewage and biomembrane uniform contact, improves space availability ratio, adds the treatment effeciency of device.
