Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated.
A kind of efficiently multiplication integrated sewage treating apparatus, including anaerobic zone, anoxic zone, aerobic zone, settling zone and select mud
Area, the anoxic zone side are equipped with the first aerobic zone；It is equipped with anaerobic zone in anoxic zone lower end, it is aerobic that anaerobic zone side is equipped with second
Area, the second aerobic area are located at the first aerobic zone lower end；First aerobic zone side is equipped with settling zone, and settling zone bottom end is to incline
Tiltedly setting in the second aerobic zone side and is located at settling zone lower end equipped with the area Ze Ni, equipped with row between settling zone and the area Ze Ni
Mud pipe, anaerobic zone, anoxic zone are equipped with the baffle plate for preventing deposition, and baffle plate setting is multiple, are staggered up and down, so that
Intake tunnel becomes " S " type；Air lift unit is equipped between the anoxic zone and the first aerobic zone, in the air lift unit
Lower end is equipped with air photohead, and the sewage and gas mixing, gas in air-lift device are attached on sewage, the dirt adhered to by gas
Water rises with gas, Lai Shixian sewage lifting to aerobic tank；First aerobic zone is equipped with multiple react with the second aerobic zone
Device photohead, reactor aeration head provide enough oxygen for activated sludge come the pollutant in water of degrading；And make activated sludge
Rolling, does not form dead zone, activated sludge is adequately contacted with sewage, to achieve the effect that processing.
A kind of efficiently multiplication integrated sewage treating apparatus and its technique, this technique is by anaerobic zone, anoxic zone, gas device
Area, aerobic zone and settling zone composition, the following steps are included:
Step 1, sewage enters from anaerobic zone, hydraulic detention time 2h；
Step 2, anaerobic zone water outlet overflows across partition and flows automatically to anoxic zone, anoxic zone lower end by anoxic zone, anaerobic zone water inlet
Equipped with air-lift device, sewage is mentioned aerobic zone, thus realize the circulation of entire technique, hydraulic detention time 2h；
Step 3, anoxic zone water outlet enters gas device area, by movable aeration plate come sewage lifting to aerobic zone,
Aerobic zone hydraulic detention time is 8h；
Step 4, aerobic zone is connected to settling zone and anaerobic zone, is partially handled water up to standard and is discharged by settling zone, precipitating
Area's hydraulic detention time is 2.2h；
Step 5, part of contaminated water flow to anaerobic zone and carries out internal circulation, and aerobic zone part of contaminated water is scarce as anaerobic zone flows automatically to
, to be thus lifted to aerobic zone, internal circulation is realized into air-lift device area in oxygen area.
Because this technique itself just has interior circulation, without separately setting interior circulation in terms of denitrogenation, and because intaking from anoxic pond
Water inlet, provides enough carbon sources for digestion reaction, without additional supplementary carbon source.Sewage treatment unit compact arrangement takes up an area face
Accumulating small, small investment, saving operating cost and facilitate later period operation maintenance is a spotlight of this technique.The either investment of early period
Or the cost of the operation maintenance in later period all falls below minimum point, in sewage treatment circle there is very strong practicability and generalization to anticipate
Justice.It is not necessarily to that other mechanical equipments are installed in pond body to realize interior circulation using gas method, saves operating cost and facilitate the later period
Operation maintenance is the another spotlight of this technique.
Efficiently multiplication integrated sewage disposal technique anaerobic unit, anoxic unit are equipped with the phenomenon that baffle plate prevents deposition hair
It is raw, it can reach without installing any equipment and meet the requirements, the unit later maintenance of equipment is not simple, at low cost.Efficiently again
Increasing integrated sewage disposal technique anaerobic unit, anoxic unit are equipped with the phenomenon that baffle plate prevents deposition generation, appoint without installation
What equipment, which can reach, meets the requirements, and the unit later maintenance of equipment is not simple, at low cost.
Be partially under settling zone it is tilted, unique structure configuration in this way can flow to automatically guaranteeing the sludge of settling zone
Aerobic zone, and sedimentation effect will not be influenced because of aerobic zone water flow fluctuation two, it is ensured that water outlet is limpid.
This technique in circulate in by aerobic unit, anaerobic unit, anoxic unit processing after can be realized denitrogenation and
Except phosphorus reaction.Because this technique itself just has interior circulation, without separately setting interior circulation in terms of denitrogenation, and because intaking from anoxic pond
Water inlet, provides enough carbon sources for digestion reaction, without additional supplementary carbon source.This process activity sludge aeration pond is in fluidised form
Belong to the formula of being thoroughly mixed, anti impulsion load is temporal plug-flow in terms of organic matter degradation, and organic pollutant is along the time
Passage and degrade；The total residence time of entire technique only has 2/3 of traditional handicraft or so, greatly save floor occupying area and
Cost of investment.
