Machine industrial wastewater.
6, after using the utility model, effluent quality can directly reach country's " regeneration of urban sewage benefit of Treated sewage reusing
With urban reclaimed water water quality " (GB/T18920-2002) standard requirements, it can satisfy resource utilization and the country of sanitary sewage
Emission request etc..Its sewage load >=300m3/ d, operating cost reduce by 50%, and processing cost is generally all in 0.35 yuan/m3With
Under.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the system diagram of the utility model.
In figure: 1-grid；2-conditioning tanks；31-large apertures are wandered about as a refugee balloon borne body fixed bed；32-cobblestone carriers are fixed
Bed；4-sterilizing equipment decontaminating apparatus；5-Aeration fans；6-middle ponds.
Specific embodiment
As shown in Figure 1, a kind of large aperture mixed carrier biochemical sewage treatment system, including the grid being connected in turn
1, conditioning tank 2, biochemistry pool and middle pond 6.The side of grid 1 is connected with cesspool sewage pipe；Aeration fan is connected in biochemistry pool
5；Sterilizing equipment decontaminating apparatus 4 is connected on water pipe between biochemistry pool and middle pond 6；Middle pond 6 is equipped with outlet pipe.
Biochemistry pool wanders about as a refugee balloon borne body fixed bed 31 by the large aperture being connected respectively with Aeration fan 5 and cobblestone carrier is fixed
Bed 32 is constituted；The wander about as a refugee side of balloon borne body fixed bed 31 of large aperture is connected with conditioning tank 2, and the other side is fixed with cobblestone carrier
Bed 32 is connected；Cobblestone carrier fixed bed 32 is connected through water pipe with middle pond 6.
Large aperture balloon borne body fixed bed 31 of wandering about as a refugee refers to as diameter to be that wandering about as a refugee for 50 ~ 350mm is long by 6.00 made of ball filling
Rice, 2.00 meters wide, high 1.80 meters of fixed bed；The interior baton round filler of different sizes equipped with diameter 10mm ~ 60mm of ball of wandering about as a refugee.
Cobblestone carrier fixed bed 32 refers to 6.00 meters long, wide as made of the cobblestone filling that diameter is 10 ~ 380mm
2.00 meters, high 1.80 meters of fixed bed form the gap of different-diameter, can control water velocity, when increasing hydraulic retention
Between.
Contain disinfection agent of chlorine dioxide in water pipe.
When work, the sanitary sewage in cesspool sewage pipe is after grid 1 enters conditioning tank 2, in 2 homogeneous of conditioning tank, so
After be introduced into wander about as a refugee balloon borne body fixed bed 31 of large aperture and carry out coagulation, sewage forms biomembrane in ball filler surface of wandering about as a refugee,
To form effect of wandering about as a refugee；It enters back into cobblestone carrier fixed bed 32 and carries out two stage treatment, form life in cobblestone carrier surface
Object film improves biochemical effects.Due to different with cobblestone interstitial different in flow rate inside and outside ball, keep solid pollutant and colloid dirty
Dye object separation is deposited in ball, generates solid-liquid separation effect；Simultaneously because the collective effect of several wander about as a refugee ball and cobblestones, makes liquid
Body residence time and solid retention time separate.Hydraulic detention time is 7 hours, and solid retention time was up to 20 days as long as.
Additionally, due in ball and the spontaneous a large amount of biomembranes of cobblestone and different types of microorganism are in several grades of aerobic/anaerobic biochemical actions
Under, so that dirty water pollutant is degraded, solids and colloid are all resolved, until generating without activated sludge.It finally will be dirty
Water further purifies reach middle water quality standard after disinfection warp in pond 6 enter outlet pipe.
