Description
Technical field
The present invention relates to sewage treatment facility, especially a kind of integrated opel oxidation ditch built-up type aerating system that is used for municipal sewage treatment industry employing.
Background technology
At present, the treatment process that sewage work uses can be divided into activated sludge process and contact oxidation method two big classes, and aeration aerating is the core technology of all these technologies, and technological process is absolutely necessary.Simultaneously, aerator also is the highest equipment of energy consumption in the sewage aerobic biological treatment system, and its energy consumption accounts for 60～70% of activated sludge process Sewage Plant total energy consumption.The quality of aerator performance directly has influence on the effect of WWT, also has influence on the running expense of Sewage Plant.
The key that guarantees the aeration aerating effect depends on aerator.Aerator mainly contains two types of blast aeration and mechanical aerations.Blast aeration system equipment is very complicated, and power consumption is big, and occurs accident such as obstruction easily; When accident such as obstruction occurring to ME; Need halt system work, all take out the water in the aeration tank to the greatest extent then and just can carry out, this maintenance mode is wasted time and energy; Increase maintenance cost, made management and maintenance also very inconvenient.Surface aeration is claimed in mechanical aeration again; Brush aeration is a comparatively widely used aeration form in oxidation ditch in mechanical aeration system; It has advantages such as simple in structure, that installation and maintenance are comparatively convenient, mechanical means is simple; But the regulation range to oxygen requirement is less, occurs the dead angle in the pond easily, and deposited phenomenon is serious.
Summary of the invention
To the deficiency of above-mentioned prior art, technical problem to be solved by this invention is that a kind of integrated opel oxidation ditch built-up type aerating system energy-conservation and easy to maintenance is provided.
In order to solve the problems of the technologies described above; The present invention provides a kind of integrated opel oxidation ditch built-up type aerating system; Comprise the surperficial plugflow aeration machine that is used for sewage plug-flow and aeration; It is characterized in that also comprise being installed at least one water-bed aeration arranging device, this aeration arranging device all passes through pipeline and is connected with blower fan.
Said aeration arranging device (2) comprises induction pipe (4); Said induction pipe (4) is vertical to be provided with; The upper end of this induction pipe (4) is provided with bend pipe, at this bend pipe front end ring flange is installed, and horizontally disposed aeration row is installed in the lower end of said induction pipe (4); The arm of supplying gas (5) and several aeration tube that laterally arranges (6) are drawn together in this aeration package; The arm (5) of supplying gas welds with several aeration tubes (6) and is connected, and said aeration tube has at least one through hole on (6), on said aeration tube (6), is with the micro-pore aeration film.
Said aeration tube is symmetrically arranged 3～6 groups.
Also comprise a fixedly support frame of aeration tube, the box of said support frame for being welded with steel; Aeration tube one end links to each other with the arm of supplying gas, and the other end links to each other with support frame.
Positively effect of the present invention is:
1. blast aeration and surperficial plugflow aeration machine combination, blast aeration equipment are used for concentrating supplies gas, the bottom aeration, and aeration efficient is high, and oxidation effect is good, improves the sewage treatment capacity that oxygen animalcule is arranged; Surface plugflow aeration machine equipment plays the effect of plug-flow and adjustment aeration, rationally regulates the unlatching platform number of surperficial plugflow aeration machine equipment, the energy that avoids waste, saves energy according to practical situation.
2. the aeration arranging device in the blast aeration all independently is provided with, and each aeration arranging device can both disassemble and not influence the works better that other aerations are arranged, and installation, convenient disassembly are convenient to the maintenance of equipment, the time and labour saving.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an aeration arranging device structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description.
Embodiment 1: referring to Fig. 1; Integrated opel oxidation ditch built-up type aerating system; It is installed in the opel oxidation ditch of triple channel; Fluidised form between raceway groove and the raceway groove is a pulling flow type, and it comprises ten surperficial plugflow aeration machines 1 that are used for sewage plug-flow and aeration and is installed in 12 water-bed aeration arranging devices 2; Four aeration arranging devices 2 all evenly are installed in three raceway grooves; The place ahead of the aeration arranging device of in outer fissure and middle ditch, installing 2 respectively is equipped with a surperficial plugflow aeration machine 1; The place ahead of two aeration arranging devices 2 of in septal fossula, being separated by respectively is equipped with a surperficial plugflow aeration machine, and each aeration arranging device 2 all is connected in parallel on to be responsible on 8 pipelines.Blower fan 3 is a roots blower in this enforcement, blast aeration and 1 combination of surperficial plugflow aeration machine, and blower fan 3 is used for concentrating supplies gas; Surface plugflow aeration machine 1 is used for the sewage plug-flow, and each aeration arranging device 2 carries out the bottom aeration at the bottom of being installed in sewage lagoon, and aeration efficient is high; Oxidation effect is good, has improved aerobic microorganism active and the reproduction speed in the sewage lagoon, thereby improves its processing power to sewage; Only need the power of control blower fan 3 just can control aeration rate, the unlatching platform number of regulating and controlling surface plugflow aeration machine 1 carries out reasonable plug-flow according to demand; The energy that avoids waste, saves energy.
Referring to Fig. 2, aeration arranging device 2 comprises induction pipe 4, and said induction pipe 4 vertically is provided with; The upper end of this induction pipe 4 is provided with bend pipe, at this bend pipe front end ring flange is installed, and horizontally disposed aeration row is installed in the lower end of said induction pipe 4; The arm 5 of supplying gas, symmetrically arranged 5 groups of aeration tubes that laterally arrange 6 are drawn together in this aeration package; The arm 5 of supplying gas welds with aeration tube 6 and is connected, and has at least one through hole on the aeration tube 6, and the suit surface is provided with the micro-pore aeration film of a lot of micropores on aeration tube 6.Aeration arranging device 2 is simple in structure, and dismounting and maintenance are all very convenient.Aeration tube 6 be symmetrically arranged several groups all can, the micro-pore aeration film is full of air expansion during air-blowing because the micro-pore aeration film is covered with the aperture of giving vent to anger, a large amount of small bubbles that air-blowing is emerged, sewage and air contact area are big during aeration, the raising dissolved oxygen amount, oxygen utilization rate is higher.
