Further, the thickness of described filter material layer (2) is 3-4m.
Further, the thickness of described packing layer (10) is 0.5-1.5m.
Further, described submersible agitator (12) rises chain and carries out elevating control by hanging.
Further, the particle diameter of described filter material layer (2) and packing layer (10) is 0.5-2mm.
Further, described submersible agitator (12) is Leaf of banana shape.
Further, described packing layer (10) is gac biologic packing material.
The beneficial effects of the utility model are:
1, the aerating system in biological filter, left side adopts the porous piping of small aperture, and gas distribution is even, and tolerance can regulate control, thereby guarantees the irregular movement of biologic packing material in reactor, strengthens the dirty filter of receiving of filtrate, is conducive to transmission and the utilization of oxygen.
2, in biological filter, right side, adopt the submersible agitator of Leaf of banana shape, under even, low rate mixing, biologic packing material and water body produce convolution streamflow regime, improve oxygen transfer efficiency, and have solved the problem that aeration head stops up.
3, one-piece construction of the present utility model has guaranteed that sewage disposal is stable, the specific surface area of filter material layer and packing layer is large, make biological filter volumetric loading high, sludge settling property is good, be easy to solid-liquid separation, biological filter buffer capacity is large, can automatically regulate concentration peak that microorganism is normally worked all the time, and the ability of anti impulsion load is strong.
4, biomembrane activity of the present utility model has double effect, and coefficient of oxygen utilization is 1.5 times of ordinary biofilter, and the water quality that goes out after processing is issued to middle water reuse in the another prerequisite of plus depth treatment facility and equipment, and sewage treating efficiency is high.
