Detailed description of the invention
Fig. 1 is a kind of specific embodiment structural schematic diagram of opel oxidation ditch described in the utility model,
Fig. 2 is a specific embodiment schematic diagram of corundum aerator;
The entitled 1- outer fissure of appended drawing reference in figure, ditch in 2-, 3- septal fossula, 4- Center Island, 5- impeller, 6- aerator.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in further detail.
Opel oxidation ditch described in the utility model, the annular gallery including three around the distribution of 4 annular concentric of Center Island,
It is from outside to inside respectively outer fissure 1, middle ditch 2 and septal fossula 3, multiple groups aerator 6 and more is distributed in septal fossula for the outer fissure, middle ditch
A real-time dissolution oxygen detection, the dissolution oxygen detection are connect with controller signals, the controller and the aerator
Control connection.
The aeration head quantity that every group of aerator includes is different, is generally arranged according to the area of outer fissure, middle ditch, septal fossula, face
Aeration head sum is more in the biggish ditch of product, as shown in Figure 1, can be in the straight way part of ditch and racetrack portion arrangement aeration dress
It sets, and can be control effectively simultaneously by aeration quantity of the valve body on aerating pipelines to every group of aerator.
In the course of work of opel oxidation ditch, the dirt containing different densities and kind quasi-microorganism is added in each ditch pond
Mud, sewage are circulated in Gou Chizhong, wherein the harmful substance contained is decomposed by microbiological treatment, sewage treatment is sequentially from outer layer
Gallery successively flows into internal layer gallery.Typically, the microorganism total amount highest of outer oxide ditch, middle layer are taken second place, and internal layer is minimum, this
In the sludge of each gallery bottom, the Process operating parameters of each gallery of oxidation ditch determine microorganism for the main existence of biology slightly
Quantity and activity, while also determining the impact resistance and final outflow water effect of the process system.
When oxidation ditch operates normally, air enters surface impeller by blower, since high-speed rotating helical axis makes axis
Certain negative pressure is formd in vivo, and air enters water body under the collective effect of blower and negative pressure, high-speed rotating at the same time to push away
It flows device blade and air bubble is cut into short grained bubble, preferably uniformly mixed with sewage, in order to improve work
Property sludge reaches better clean-up effect to the utilization efficiency of oxygen.
The oxidation ditch it is outer, in, septal fossula be respectively set dissolved oxygen on-line measuring device, each gallery of real-time detection it is molten
Oxygen concentration is solved, to pass through according to the valve body on the dissolved oxygen concentration and each air pipe line for flowing into the pollution level of sewage, each ditch
Controller controls the aeration power of aerator, such as can be adjusted to the operating parameter of blower and then control aeration function
Rate achieves energy-saving and emission reduction purposes.
Aerator preferably uses corundum aerator, as shown in Fig. 2, corundum aerator, which is called, does micro-hole aerator, corundum
Aerator is a kind of economical and effective processing method in the biochemical treatment of sewage, and there are many factor for improving Biochemical Treatment
Wherein main factor first is that there is sufficient dissolved oxygen in water, microporous ceramic aerator, can make oxygen in air by
Air blower compression is uniformly spread in water through micro-pore ceramic aerator, since bubble is tiny, compared with traditional aerator, and effect
Rate improves 5 times, and operation energy consumption reduces by 3 times, and ceramic micropore aerator not only has efficient technical performance, with more anti-
The particular advantages that burn into is ageing-resistant, the service life is long, are ideal one of oxygenate apparatus.
So that air is entered sewage from bottom of pond using corundum aerator, compared with original surface aeration equipment, greatly increases
Stroke of the gas in entire process system to increase air in the residence time of entire process system improves sky
The utilization rate of gas；The aerating system of dispersed placement avoids air and excessively intensively enters sewage body, causes local dissolution oxygen mistake
It is surplus, the too low phenomenon of utilization rate；Meanwhile from oxidation ditch bottom when concentration of wastewater changes, need to adjust dissolution in each ditch gallery
Oxygen concentration maintains life condition, quantity and the type of each ditch gallery dominant bacteria, thus avoid in sewage disposal process due to
Sewage composition and microorganism collocation are not suitable for causing the mortality of microorganism, influence sludge quality, Austria after being adjusted
Bell's oxidation ditch impact resistance is enhanced.
More impellers 5 can be set in oxidation ditch, and impeller cooperates the operation of distributing multiple spot bottom aerator, oxygen
The medium changed in ditch mixes more evenly, and air utilization efficiency is higher, and treatment effect is more preferable.The position of aerator installation is usually set
It sets except 5m immediately ahead of impeller.The depth of usual septal fossula is deeper than outer fissure and middle ditch, wide convenient for drawing water direct outlet from bottom
Degree mutually should be less than outer fissure and middle ditch, and septal fossula water velocity can be improved, and be conducive to circulation, while keeping three bar ditch flows equal.
Using opel oxidation ditch described in the utility model, make air from pond using distributing bottom multiple spot aerator
Bottom enters sewage, compared with original surface aeration equipment, stroke of the gas in entire process system is considerably increased, to increase
Add air in the residence time of entire process system, improves the utilization rate of air；The aerating system of dispersed placement avoids
Air excessively intensively enters sewage body, causes local dissolution oxygen excess, the too low phenomenon of utilization rate；The aerator makes to aoxidize
Ditch is outer, in, interior each gallery have the characteristics that the technological parameter of suitable self-operating, tame out an advantage for suitable a gallery technological parameter
Strain improves the utilization efficiency and impact resistance of air in oxidation ditch with this, and being finally reached is not influencing outlet effect
Meanwhile reducing the purpose of water process specific energy consumption.
The oxidation ditch it is outer, in, interior each gallery dissolved oxygen on-line measuring device, each gallery of real-time detection is respectively set
Dissolved oxygen concentration, thus according to the valve on the dissolved oxygen concentration and each air pipe line for flowing into the pollution level of sewage, each gallery
Body is adjusted the operating parameter of blower, is finally reached the purpose of energy-saving and emission-reduction.
Previously described each preferred embodiment for the utility model, the preferred embodiment in each preferred embodiment
If not obvious contradictory or premised on a certain preferred embodiment, each preferred embodiment can be arbitrarily superimposed
It is applied in combination, the design parameter in the embodiment and embodiment is merely to clearly state the utility model of utility model people
Verification process, not to limit the scope of patent protection of the utility model, the scope of patent protection of the utility model still with
Subject to its claims, the variation of equivalent structure made by all specifications and accompanying drawing content with the utility model, similarly
It should be included in the protection scope of the utility model.
