Description
Technical field
The present invention relates to a kind of septum type overflowing weir shaped water discharging device, belong to the water outlet equipment technical field of sewage disposal.
Background technology
At present, along with the extensive use at home of sequencing batch active sludge (hereinafter to be referred as SBR) sewage treatment process, constantly applying of position, particularly improved on its basis various Continuous Flow Hengshui sequencing batch active sludge proposed by the intermittently requirement (stopping water outlet during aerated reaction) of water outlet of the cycle of operation traditional effluent weir.In order to satisfy this requirement, foreign vendor releases a kind of air outlet weir through research, its structure as shown in Figure 1, among Fig. 1, the 2nd, intake valve, the 6th, go out water channel, the 7th, outlet pipe, the 8th, air bleeding valve, the 9th, distribution pipeline, the 10th, water outlet, the 11st, airhood.There is a hydrolock airhood this effluent weir top, and is main by the air pressure in the control effluent weir, and the outer liquid level of regulating weir is come effluent functions sexual refractoriness performance period.This device is after sewage treatment plant puts into operation at home, repeatedly excessive because of pressurizeing, reasons such as water flow is unstable, race mud have had a strong impact on effluent quality, and owing to its effluent weir is sealed by airhood fully, cause in servicely being difficult in time to find and to solve whether effluent weir weir plate height is consistent, whether weir plate has hung with problems such as suspension, if and the untimely solution of these problems will cause the end result-effluent quality of sewage disposal to have a strong impact on.This device is since putting into operation, though several times improve, it is little still to produce effects so far; Particularly the sewage disposal plant effluent requirements in water quality is improved constantly, fundamentally address the above problem and become to restrict one of principal element that this technology further promoted along with domestic.
Summary of the invention
The objective of the invention is deficiency and defective at the prior art existence, a kind of septum type overflowing weir shaped water discharging device is proposed, with solve the pressurization that air outlet weir exists excessive, run problem such as mud, and make operating personnel can observe directly the ruuning situation of discharging device, be convenient in time find and deal with problems, make the equipment operation more reliable.
The septum type overflowing weir shaped water discharging device that the present invention proposes comprises the water stream channel that constitutes between air chamber, water outlet downflow weir and the air chamber of a C font and the water outlet downflow weir.Air chamber is connected with the distribution pipeline by pipeline.Water outlet downflow weir and air chamber are integrated and form a water outlet module and place cesspool to go out the outer periphery of water channel, and water stream channel of formation is fixed with a plurality of air bags between the air chamber in the water outlet module and the water outlet downflow weir in the water stream channel, and air bag is connected with air chamber.
The septum type overflowing weir shaped water discharging device that the present invention proposes compared with prior art, has following characteristics and advantage:
1, discharging device of the present invention is by charging and discharging gas and control out the water outlet of water channel cycle being located at the air bag that overflows between water channel and the scum board, need not to resemble the air outlet weir shown in Figure 1 airhood of cover on the water outlet channel, thereby just can fundamentally avoid malfunctioning because of detecting in the airhood, make the airhood internal pressure too high, the water seal that a large amount of air overcome around the airhood is overflowed in airhood, it is moving that cover body is swung sideward, the problem that shortens the service life of airhood.Simultaneously, also overcome because of in precipitation and the air agitation of overflowing from airhood during water outlet water body adverse effect that mud-water separation is brought on every side;
2, because this discharging device need not to establish airhood, make the operation personnel can observe directly the operational effect of effluent weir, in time adjust and safeguard effluent weir according to ruuning situation, provide reliable assurance improving effluent quality thereby be convenient to the operations staff;
3, because this discharging device is not to control water outlet by establishing airhood, therefore, avoided since airhood pressure relief pipe restriction and the time form negative pressure when being everlasting big water flow, the race mud problem that the serious disturbance of pool inner water body is caused that causes water yield sharply to increase causing has improved effluent quality;
4, this device need not to establish heavy airhood on effluent weir, has both reduced construction investment, has significantly reduced the construction and installation difficulty again; Control element is few, and is easy and simple to handle, is convenient to safeguard.
5, this device is a modularized equipment, can carry out scene assembling according to water outlet channel length, applied widely than existing air outlet weir.

The specific embodiment
The septum type overflowing weir shaped water discharging device that the present invention proposes, its structure comprise the water stream channel that constitutes between air chamber 3, water outlet downflow weir 5 and the air chamber of a C font and the water outlet downflow weir as shown in Figure 2.Air chamber is connected with distribution pipeline 9 by pipeline respectively.Water outlet downflow weir 5 and air chamber 3 are integrated and form a water outlet module and place cesspool to go out the outer periphery of water channel 6, constitute a water stream channel between air chamber in the water outlet module and the water outlet downflow weir, be fixed with a plurality of air bags 4 in the water stream channel, air bag 4 is connected with air chamber 3.
Apparatus of the present invention are provided with fixing air bag between the scum board in the water outlet channel that has the water outlet downflow weir and the outside thereof, periodically air bag is charged and discharged gas, block or open wide out the water stream channel of water channel, to realize out the purpose of water channel periodic intermittent overflow water outlet.
Introduce the course of work of apparatus of the present invention in detail below in conjunction with accompanying drawing:
From Fig. 3 and Fig. 5 as can be seen, water outlet module of the present invention is made up of a C font air chamber 3 and water outlet downflow weir 5, this module is fixed on out the outer periphery of water channel 6.When the needs water outlet, as shown in Figure 2, intake valve 2 cuts out, and air bleeding valve 8 is opened when arranging simultaneously, the air in the air bag 4 of each module, under the synergy of inside and outside differential pressure and hydraulic pressure, enter atmosphere through coupled logical air chamber 3 and air pipe line thereof, the volume of air bag 4 sharply dwindles, thereby the water stream channel between the air bag is opened wide rapidly, treated water outlet flows into out water channel 6 by this passage through water outlet downflow weir 5, and enters outlet pipe 7 after confluxing.When needs stop water outlet, as shown in Figure 4, intake valve 2 is opened, air bleeding valve 8 is closed simultaneously, pressure-air from air blast is pressed in the air bag 4 by air chamber 3 through distribution pipeline 9, and the volume of each air bag is expanded rapidly, thereby has blocked the water stream channel between the air bag, water outlet can't be flowed into out in the water channel through water outlet downflow weir 5, reach the purpose that stops water outlet.
