Description
Technical field
The present invention relates to a kind of aerating apparatus, particularly relate to a kind of aerating apparatus of biological sewage treating pond.
Background technology
Aeration refers to the process being forced by the oxygen in air to shift in liquid, its objective is and obtains enough dissolved oxygens.In addition, aeration prevents pond inner suspension body from sinking in addition, strengthens the object that in pond, organism contacts with microorganism and dissolved oxygen.Thus in guarantee pond microorganism under the condition having sufficient dissolved oxygen, to oxygenolysis organic in sewage, aeration is a kind of important method of sewage disposal, in aeration process oxygenous bubble whether evenly, stable, controlled quality and the efficiency directly having influence on sewage disposal of size.
In the prior art at present, generally be provided with some aeration tubes on single airway, the easy like this aeration tube of close airway air feed port that causes is different with the aeration tube air demand away from air feed port, the tube head of another every root aeration tube and the air demand of pipe tail different, make the aeration of whole aeration tank uneven, every root aeration tube air demand size is also uncontrollable; In order to provide enough dissolved oxygens in the water in biological sewage treating pond, people use blower fan pressurized air to carry out inflation aeration by some aeration tubes of submerged, when there is the faults such as wearing and tearing or perforation on the other hand when certain root aeration tube, closure systems is needed to stop aeration even draining Chi Zhongshui to overhaul, within the repair time, cannot in time for the decomposing organism in biological treatment tank provide enough solubility oxygen, decomposing organism produces a point mortality situation.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, provides a kind of aerating apparatus of biological sewage treating pond.Can make sewage treatment process aeration evenly, stable, size is controlled, aerating apparatus maintenance is convenient, and aeration tube can not shut down replacing.
In order to solve the problems of the technologies described above, embodiments provide a kind of aerating apparatus of biological sewage treating pond, sewage lagoon edge is provided with A airway and B airway, described A airway and B airway have common inlet mouth, some the aeration tubes be arranged at bottom described sewage lagoon are provided with between described A airway and B airway, described every bar aeration tube two ends connect A airway and B airway respectively by valve, 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, Bidirectional adjusting valve is provided with in the middle part of described aeration tube.
Further, described aerating pore surface is provided with the respiratory membrane of openable.
Further, respiratory membrane is the one 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 plastic microporous aeration tube.
Further, described A airway end and B airway end are communicated with by communicating pipe and form air circulation loop.
Implement the embodiment of the present invention, have following beneficial effect: A airway is connected with aeration tube by valve with B airway by the present invention, sewage treatment process aeration evenly, stable, size is controlled; Corresponding out of order aeration tube can be closed carry out overhauling and the work not affecting other aeration tubes when aeration tube breaks down, maintenance is made to be down to minimum on the impact that microbial growth environment produces, and Bidirectional adjusting valve is set makes the aerating regulation of every root aeration tube to evenly, avoid local excessive or too low aeration to produce the microorganism of sewage lagoon to impact, affect wastewater treatment efficiency.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, 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, an opposite side of sewage lagoon arranges A airway 10a and B airway 10b, one end of A airway 10a with B10b is communicated with and is provided with common inlet mouth 11 at middle part, between A airway 10a and B airway 10b, be provided with some aeration tubes 20, the size of the air pressure that the quantity of aeration tube can input with airway and treatment tank carries out actual set.
Aeration tube 20 two ends are connected with A airway 10a and B airway 10b respectively, aeration tube 20 is arranged at the bottom for the treatment of tank in up concave type, aeration tube 20 is connected A airway 10a and B airway 10b by valve 21a with 21b, and valve 21a, the two ends of 21b are respectively by flange and aeration tube 20 and A airway 10a, B airway 10b is connected, valve 21a, 21b is except the air demand of adjustable aeration tube 20, also can realize not overhauling aeration tube 20 with shutting down, valve-off 21a can be selected when needs are retrieved, 21b, aeration tube 20 is therebetween taken out and keeps in repair, and do not affect the work that other are connected to the evident aeration tube of airway, to be down to minimum on the impact of biological sewage treating pond because aeration tube fault produces.
In order to the aeration realizing aeration tube is even, the middle part of aeration tube 20 is provided with Bidirectional adjusting valve 22, structural representation as shown in Figure 2, Bidirectional adjusting valve 22 is made up of an overhead door that can swing 221, when pressure imbalance appears in aeration tube about 20 limit, can be able to automatically adjust to Bidirectional adjusting valve 22, make aeration even, be reduced to minimum to the impact of the biological respinse environment in treatment tank, be conducive to the biological process 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 pressure of A airway 10a, B airway 10b balanced further.
Aeration tube 20 has some aerating pores 30, the diameter of aerating pore is at below 1mm, and prevent aerating pore from being blocked by dirt further, as shown in Figure 3, the respiratory membrane 31 of openable is provided with on aerating pore surface, respiratory membrane 31 can be made into by a kind of material in Ethylene Propylene Terpolymer, silica gel, fluorine glue or butyronitrile rubber film, is preferably silica gel in the present embodiment and makes respiratory membrane.
Fig. 3 is the structural representation of aerating pore, be arranged on the respiratory membrane 31 on aerating pore surface, offer three cracks, road 32, in aeration process, aeration tube 20 internal pressure is greater than pond hydraulic pressure, three cracks, road 32 of respiratory membrane 31 are in diastole open mode, and aerating pore is exhausted, when aeration stops, three cracks, road 32 of respiratory membrane 31, in closing condition, prevent sewage and dirt from being entered in aeration tube by aerating pore.
Embodiment 2:
In the present embodiment, the sewage lower to turbidity, aeration tube 20 selects plastic microporous aeration tube, not only can make aeration tube 20 durable, and the bubble fine and even more that plastic microporous is disengaged, all the other structures of the embodiment of the present invention 2 and effect are with embodiment 1, and the present embodiment is in this not repeat specification.
