Abstract
The embodiment of the invention discloses an aerating device for a biological sewage treatment tank. The aerating device is characterized in that a gas-guide tube A and a gas-guide tube B are arranged on the edge of a sewage tank and share a gas inlet, a plurality of aerating tubes sinking into the liquid surface of the sewage tank are arranged between the gas-guide tube A and the gas-guide tube B, two ends of each aerating tube are respectively connected with the gas-guide tube A and the gas-guide tube B through valves, and a plurality of aerating micropores are formed in the surfaces of the aerating tubes. According to the aerating device, the gas-guide tube A and the gas-guide tube B are connected with the aerating tubes through the valves, and the aeration is uniform and stable and is controllable in quantity in a sewage treatment process; when the aerating tubes malfunction, the corresponding malfunctioned aerating tubes can be closed to be repaired without influencing the working of the other aerating tubes, and thus the influence caused by the repairing to a microorganism growth environment can be minimized; by virtue of bidirectional regulating valves, the aeration of each aerating tube is regulated to be uniform, the impact, caused by local overmuch or excessive-low aeration, on microorganisms in the sewage tank is avoided, and thus the influence on the sewage treatment effect is eliminated.
Description
Technical field
The present invention relates to a kind of aerating apparatus, relate in particular to a kind of aerating apparatus of biological sewage treating pond.
Background technology
Aeration refers to forces by airborne oxygen the process shifted in liquid, its objective is and obtains enough dissolved oxygens.In addition, aeration prevents that pond inner suspension body from sinking, and strengthens the purpose that in pond, organism contacts with microorganism and dissolved oxygen in addition.Thereby in the assurance pond there be under the condition of sufficient dissolved oxygen microorganism, to organic oxygenolysis in sewage, aeration is a kind of important method of sewage disposal, whether even, stable, big or small controlled quality and the efficiency that directly has influence on sewage disposal of oxygenous bubble in aeration process.
In the prior art at present, generally to be provided with some aeration tubes on single airway, the easy like this aeration tube of close airway air feed port that causes is with different away from the aeration tube air demand of air feed port, the air demand of the tube head of another every aeration tube and pipe tail is different, make the aeration of whole aeration tank inhomogeneous, every aeration tube air demand size is also uncontrollable; In order in the water in the biological sewage treating pond, to provide enough dissolved oxygens, people use blower fan pressurized air to be inflated aeration by some aeration tubes of submerged, on the other hand when the faults such as certain root aeration tube appearance wearing and tearing or perforation, need closure systems to stop aeration and even drain Chi Zhongshui to be overhauled, within the repair time, can't be in time for the decomposing organism in biological treatment tank provides enough solubility oxygen, decomposing organism produces a minute mortality situation.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, a kind of aerating apparatus of biological sewage treating pond is provided.Can make the sewage treatment process aeration even, stable, big or small controlled, the aerating apparatus maintenance is convenient, and aeration tube can not shut down replacing.
In order to solve the problems of the technologies described above, the embodiment of the present invention provides a kind of aerating apparatus of biological sewage treating pond, be provided with A airway and B airway on the sewage lagoon edge, described A airway and B airway have common inlet mouth, be provided with some the aeration tubes that are arranged at described sewage lagoon bottom between described A airway and B airway, described every aeration tube two ends connect A airway and B airway by valve respectively, and described aeration tube surface has some aerating pores.
Further, described valve two ends are connected with described airway, aeration tube respectively by flange.
Further, described aeration tube middle part is provided with Bidirectional adjusting valve.
Further, described aerating pore surface is provided with the respiratory membrane of openable.
Further, respiratory membrane is a kind of in Ethylene Propylene Terpolymer, silica gel, fluorine glue or butyronitrile rubber film.
Further, the diameter of described aerating pore is below 1mm.
Further, described aeration tube is the plastic microporous aeration tube.
Further, described A airway end and B airway end were communicated with and are formed air circulation loop by communicating pipe.
Implement the embodiment of the present invention, have following beneficial effect: the present invention is connected the A airway by valve with the B airway with aeration tube, and the sewage treatment process aeration evenly, stable, size is controlled; When breaking down, aeration tube can close that corresponding out of order aeration tube is overhauled and the work that do not affect other aeration tubes, the impact that maintenance is produced the microbial growth environment is down to minimum, and aerating regulation that Bidirectional adjusting valve makes every aeration tube is set to evenly, avoid local excessive or too low aeration to impact the microorganisms of sewage lagoon, affect wastewater treatment efficiency.
The accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present invention;
Fig. 2 is the structural representation of Bidirectional adjusting valve;
Fig. 3 is the structural representation of aerating pore.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment 1:
With reference to the structural representation of the present invention shown in Fig. 1.
The aerating apparatus of biological sewage treating pond of the present invention, A airway 10a and B airway 10b are set on an opposite side of sewage lagoon, the end connection of A airway 10a and B10b also is provided with common inlet mouth 11 at middle part, be provided with some aeration tubes 20 between A airway 10a and B airway 10b, the air pressure that the quantity of aeration tube can be inputted with airway and the size for the treatment of tank are carried out actual set.
For the aeration of realizing aeration tube even, be provided with Bidirectional adjusting valve 22 on the middle part of aeration tube 20, structural representation as shown in Figure 2, Bidirectional adjusting valve 22 consists of an overhead door that can swing 221, when pressure imbalance appears in aeration tube 20 limits, left and right, can automatically adjust to Bidirectional adjusting valve 22, make aeration even, the impact of the biological respinse environment in treatment tank is reduced to minimum, is conducive to the biological processing to sewage, improve processing efficiency.
As the further improvement of the embodiment of the present invention, the other end of A airway 10a, B airway 10b was connected by communicating pipe 12, made the pipeline gas of A airway 10a, B airway 10b press further balanced.
