Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model sewage multi-stage filtration systems.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of sewage multi-stage filtration systems of the utility model, it includes cesspool 1, reaction tank 2 and filtering
Pond 3, specifically, the cesspool 1 are located at 2 top of reaction tank；Cesspool 1 is equipped with blow-off pipe 11, and 4 He of water wheels is equipped in reaction tank 2
Biological rotating disk 5；Water wheels 4 are located at the underface of blow-off pipe 11；In order to ensure that the water excluded in blow-off pipe 11 can drive 4 turns of water wheels
Dynamic, blow-off pipe 11 is located at right over water wheels at 3-6 meters；It can certainly be increased and decreased according to topography；4 central part of water wheels and biology
The shaft of turntable 5 is fixedly connected；The other end of 5 shaft of biological rotating disk is fixed on 2 inner wall of reaction tank by bearing；The utility model
In biological rotating disk 5 may be used in background technology, its disc 51 be by n angle be 360 °/n fan-shaped sheet body combine and
At full circle body, wherein n be even number；Reaction tank 2 is equipped with overflow port 21；Overflow port 21 connects filtering ponds 3 by overflow pipe 22
Bottom；It is equipped with quartz sand layer 31, activated carbon fiber layers 32, softening resin layer 33 and filter in filtering ponds 3 successively from bottom to up
Layer 34；Filtering ponds 3 are equipped with drainpipe 6.
Whether the water for the ease of exclusion in detection drainpipe 6 is up to standard, and water quality testing meter 61 is equipped at drainpipe 6；When
So in order to avoid below standard water emits, solenoid valve 62 is additionally provided in drainpipe 6；Drainpipe 6 connects return duct 7；Reflux
