Description
Technical field
The utility model relates to waste disposal plant, is specifically related to a kind of efficient oxygenation drop urban wastewater treatment device.
Background technology
Along with the development of sewage disposal cause, the constantly progress of the sewage treatment process of China and equipment, the sewage disposal device in city is gradually improved, and existing waste disposal plant obtains application in municipal sewage plant of China.But the puzzlement of the problem such as difficult by technology and equipment type selecting, investment is large, running cost is high, the sewage pollution problem in cities and towns fails to solve very well for a long time.Particularly along with the fast development of Development of China's Urbanization, this problem is more aobvious outstanding.At present, 1500-1800 yuan/ton of water of the ratio of newly-built urban wastewater treatment firm investment, the ratio of the running cost of sewage work is 0.5-0.8 unit/1 ton of water, and its expense is too high, and cities and towns are difficult to accept.Therefore, explore, exploitation is applicable to cities and towns, and have that investment is little, running cost is low, less energy consumption, quality of sewage disposal are good, take up an area less, the simple sewage disposal device of good practical effect, Operation and Maintenance is necessary.
At present, although the technology for small-sized sanitary sewage disposals such as Urban Areas mainly contains septic tank, land treatment systems and stabilization pond, active sludge and biomembrance process three major types, septic tank significantly can reduce concentration of suspension, water outlet is still difficult to reach integrated wastewater discharge standard.Then civil engineering costs is higher for the unpowered sewage disposal device improved through septic tank, can not adapt to the fluctuation of water quality, the water yield in operational process, is difficult to ensure effluent quality.Land treatment systems has the various ways such as slow filter, fast filter, wetland, but its floor space is large; Stabilization pond is subject to weather effect again, is difficult to popularize.Although activated sludge process and biomembrance process can obtain good treatment effect, but can produce the variety of problems in that face of operational management.
Utility model content
For the problems of the prior art, the utility model provides that a kind for the treatment of effect is good, investment and working cost is low, it is simple to safeguard, provide a kind of efficient oxygenation drop urban wastewater treatment device.
For realizing above technical purpose, the technical solution of the utility model is: a kind of efficient oxygenation drop urban wastewater treatment device, comprise anaerobic pond, drop oxygenation and contact oxidation pond, artificial swamp and the Buffer Pool for carrying out denitrification process, described anaerobic pond, drop oxygenation and contact oxidation pond, artificial swamp connect successively, also comprise Buffer Pool, described Buffer Pool is connected with anaerobic pond and drop oxygenation and contact oxidation pond respectively, described anaerobic pond is provided with sanitary sewage water inlet place, and described artificial swamp is provided with sanitary sewage water outlet place.
As improvement, described anaerobic pond is provided with irrigation mouth.
As improvement, the physical features of the Buffer Pool of described denitrification process is lower than the physical features in drop oxygenation and contact oxidation pond.
As improvement, the physical features in described drop oxygenation and contact oxidation pond is lower than the physical features of anaerobic pond.
As improvement, between described drop oxygenation and contact oxidation pond and anaerobic pond, be also provided with independently backflow channel.
As can be seen from the above description, the utility model possesses following advantage: this technique is made up of anaerobic pond, drop oxygenation and contact oxidation pond and artificial swamp three processing units, drop oxygenation oxidation utilizes water pump lifting, fall nature oxygenation step by step, reducing organic while, remove the pollutent such as nitrogen, phosphorus, the process of water part, plunge pool backflow denitrification, part enters after Buffer Pool can remove the pollutent such as nitrogen, phosphorus further and passes back into anaerobic pond, such design improves the clearance of nitrogen, all the other flow into artificial swamp and carry out subsequent disposal, except denitrification phosphorus.Such design can realize that investment is less, but sanitary sewage disposal effect is higher, makes full use of physical features advantage simultaneously thus to reduce or without water pump lifting, thus realizing the lower effect of energy consumption.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of efficient oxygenation drop urban wastewater treatment device of the present utility model.
Reference numeral: 1, anaerobic pond, 2, drop oxygenation and contact oxidation pond, 3, artificial swamp, 4, Buffer Pool.
Embodiment
As shown in Figure 1, a kind of efficient oxygenation drop urban wastewater treatment device, it is characterized in that: comprise anaerobic pond 1, drop oxygenation and contact oxidation pond 2, artificial swamp 3 and the Buffer Pool 4 for carrying out denitrification process, described anaerobic pond 1, drop oxygenation and contact oxidation pond 2, artificial swamp 3 connect successively, also comprise Buffer Pool 4, described Buffer Pool is connected with anaerobic pond 1 and drop oxygenation and contact oxidation pond 2 respectively, described anaerobic pond 1 is provided with sanitary sewage water inlet place, and described artificial swamp is provided with sanitary sewage water outlet place.
Described anaerobic pond 1 is provided with irrigation mouth.
The physical features of the Buffer Pool 4 of described denitrification process is lower than the physical features in drop oxygenation and contact oxidation pond 2.
The physical features in described drop oxygenation and contact oxidation pond 2 is lower than the physical features of anaerobic pond 1.
Independently backflow channel is also provided with between described drop oxygenation and contact oxidation pond 2 and anaerobic pond 1.
This technique is made up of anaerobic pond, drop oxygenation and contact oxidation pond and artificial swamp three processing units.Drop oxygenation oxidation utilizes water pump lifting, fall nature oxygenation step by step, reducing organic while, remove the pollutent such as nitrogen, phosphorus, the process of water part, plunge pool backflow denitrification, part enters after Buffer Pool can remove the pollutent such as nitrogen, phosphorus further and passes back into anaerobic pond, and such design improves the clearance of nitrogen, all the other flow into artificial swamp and carry out subsequent disposal, except denitrification phosphorus.Such design can realize that investment is less, but sanitary sewage disposal effect is higher, makes full use of physical features advantage simultaneously thus to reduce or without water pump lifting, thus realizing the lower effect of energy consumption.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model.Those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
