Description
Technical field
The invention belongs to environmental project technical field of sewage, the specially treatment technology of domestic sewage in rural areas.
Background technology
China's villages and small towns territorial scope is wide, and urban residents are sparsely populated, and the difference such as economic level, habits and customs is larger, rural area
The source of sanitary sewage, water quality, water complexity are various, thus determine that the selection of rural domestic sewage treatment process, engineering are built
If with many complexity such as investment, operation and management mode.In the more dispersed rural area of resident, large area, length are built
The sewage collecting pipe network system of distance is not only invested greatly, and the sewage transport of long range be present, sewage
Collection rate is not high, therefore should not be processed using the method for focusing on.
The existing technology suitable for domestic sewage in rural areas decentralized processing can be divided into two classes according to the difference of processing mode：One
Class is traditional biological treatment mode, and including aeration tank, biofilter, oxidation ditch, sbr reactor device etc., this kind of handling process goes out
Water quality stabilizing, capital cost are low, floor space is small, but complex management and operating cost is higher；Equations of The Second Kind is land treatment systems side
Method, such as stabilization pond, artificial swamp etc., this kind of handling process pollutants removal rate is high, management is simple, operating cost is low, but accounts for
Ground area is big, and capital cost is of a relatively high.
The content of the invention
It is an object of the invention to provide a kind of integrated form biological bed and the method for the treatment of rural scattered domestic sewage.
A kind of method that the present invention is integrated form biological bed and treatment rural scattered domestic sewage, integrated form biological bed,
Including water inlet pipe 1, anaerobic zone 2, control room 3, air blower 4, intake pump 5, reflux pump 6, the first weir divider 7, baffle plate 8, aerobic
Area 9, the second weir divider 10, filtering area 11, aeration tube 12, polyurethane foam filler 13, quartz sand layer 14, haydite floor 15, hold
Support layer 16, outlet pipe 17, the integrated form biological bed is made up of anaerobic zone 2, aerobic zone 9, filtering area 11 and control room 3, described
Control room 3 is located at the top of anaerobic zone 2, is internally provided with air blower 4, intake pump 5, reflux pump 6, the anaerobic zone 2 and aerobic zone 9
Internal filled polyurethane foam stuffing 13, the filtering area 11 is from the bottom to top successively by supporting layer 16, haydite layer 15, quartz sand layer
14 compositions.
Using above-described integrated form biological bed, the method for processing rural scattered domestic sewage, its step is：
（1）Sewage flows into anaerobic zone 2 by intake pump 5 through water inlet pipe 1；
（2）Sewage runs from bottom to top in anaerobic zone 2, and pollutant is attached to the anaerobe on polyurethane foam filler
Decompose；
（3）Entered into aerobic zone 9 through the sewage after anaerobic fermentation, pollutant is further divided in the presence of aerobic microbiological
Solution；
（4）A water outlet part for aerobic zone 9 is back to anaerobic zone 2 by reflux pump, and a part flow to filtering area 11 certainly, through filtering
The clear water obtained after layer filtering can be used as reclaimed water, that is, complete the treatment of rural scattered domestic sewage.
The present invention has advantages below compared with prior art：1. in the present invention, control room is arranged on anaerobic zone top, one
Aspect can make anaerobic zone form a closing space, there is provided more preferable anaerobism service condition, on the other hand, can make equipment knot
Structure is compact, reduces floor space.2. in the present invention, using polyurethane foam filler as the carrier of growth of microorganism, compared to normal
The carriers such as haydite, zeolite, the material proportion is small, porosity big, and load of microorganisms amount is big, and microbial film is difficult for drop-off,
It is more beneficial for microbial growth.3. in the present invention, anaerobic zone filler natural packing, in turbulent fluctuation shape in situ under flow action
State, can mitigate the suspended solid in sewage and block filler to the loss of flood peak and the influence of clearance, therefore required backwash frequency
It is very low；Aerobic zone filler under aeration gas flow effect, in fluidized state, without clogging, without backwash.Entered using batch (-type)
Water mode, is conducive to the endogenous digestion of microorganism in biological bed, reduces the yield of sludge, base in biological bed anaerobism and aerobic zone
This not spoil disposal.4. in the present invention, filter layer can further retain suspension, colloidal particles and microorganism for removing in water etc., make
Water outlet reaches reclaimed water matter standard, and alleviate rural area water-deficient area uses aqueous condition.
