Description
Technical field
The utility model relates to a kind of sewage disposal station-service aerated grit chamber, particularly a kind of at setting pot leading portion aeration in, the aerated grit chamber of back segment not aeration.
Background technology
Setting pot is for removing sand grains contained in the former water of sewage treatment plant, and to prevent sand grains from entering follow-up structures blocking pipe duct, wearing and tearing pump, occupy basin's effective volume, aerated grit chamber is one of principal mode of setting pot.
The major constituents of aerated grit chamber comprises an elongated rectangular shape pond, is called setting pot, has a sand catcher to pass through total length at the bottom of pond, and pond, both sides base slope is to sand catcher; Water inlet is located at the side wall upper part of setting pot one end, or is located at end wall top near sidewall locations; Water inlet homonymy, has aeration tube near the certain depth of water of side wall, and aeration tube generally passes through setting pot total length to be arranged, but is uniform air distribution and be divided into some sections of air feed, whole pond is arranged one inhales sand purlin car.
During operation, enter setting pot containing sand sewage from water inlet, flow to the setting pot other end and enter pipe duct below and structures; Pressure-air from air compressor leads in pond by aeration tube, forms the mixing wastewater with air stream risen near pool wall, thus drives the pool inner water bodily form transversely circulation; Water flows to water side from water inlet end on the other hand, certainly exists the longitudinal flow along setting pot length direction, then longitudinally stream superposes with cross current, constitutes the helical flow in pond; Sand grains is sedimentation under gravity, drops down onto after at the bottom of pond and enters sand catcher along pond bottom sloping; Inhale sand purlin car back and forth to walk along setting pot length direction, by sand setting sucking-off in sand catcher.
The object of aeration is disturbance water body and forms spiral flow field, thus wash-out sticks to the organic matter of sand grain surface as far as possible, for sand sedimentation and subsequent treatment create favorable conditions.
Research and a large amount of operative practice show: the little then soil washing of aeration rate is poor, and sand setting content of organics is high, is also unfavorable for adhering to organic small particle diameter sand fallout; Aeration rate is large then both consumed the energy more, in turn enhanced disturbance, was unfavorable for the sedimentation of sand grains.Aeration is disturbance, and precipitation then must disturbance cancelling, and a lot of aerated grit chamber operational effect is undesirable, its basic reason be disturbance and precipitation this to the contradiction being difficult to be in harmonious proportion.Therefore, need to improve existing aerated grit chamber.
Utility model content
For solving the contradiction between the disturbance of existing aerated grit chamber wash-out and sedimentation, the utility model devises the aerated grit chamber that a kind of leading portion concentrates aeration, near the water inlet of this setting pot and below in one section of flow process, concentrate enhanced aeration, abundant disturbance water body and entrained sand grains thereof, reach wash-out object; Back segment on stream, water body turbulence intensity decays because not having aeration, for sand fallout in water creates favourable mechanical condition.Thus improving sand grains clearance, aeration rate is easy to control, and shortens the running distance inhaling sand purlin car, is conducive to energy-conservation and reduces machine loss.
The utility model is achieved through the following technical solutions.
Leading portion concentrates the aerated grit chamber of aeration, is provided with the pond body of long cuboid, and be provided with the sand catcher that passes through total length at the bottom of pond, pond base slope is to sand catcher; Water inlet is located at the side wall upper part of body one end, pond, and water inlet homonymy pool wall bottom is provided with aeration tube, arranges a suction sand purlin car above the body of pond; It is characterized in that: described aeration tube is three row aeration tubes, arrange along setting pot length direction from setting pot water inlet end, aeration tube laterally or longitudinally arrangement, account for not whole pond body bottom lengths first three/1/1 to two between, Chi Tizhong, back segment do not establish aeration tube.
The utility model improves further and the additional project of enforcement is:
Described aeration tube is Collapsible structure, and the aeration head that aeration tube is arranged is for convenience of the spiral rotary access node structure of dismounting.
Be provided with online dissolved oxygen detection probe before, during and after in the body of pond, this probe carries out signal with the PLC controlling aeration air pump switch amount and is connected.
Described suction sand purlin car is provided with timer, and this timer carries out timing open and close controlling with the run switch of purlin car and is connected.
Described suction sand purlin car is provided with camera, and is provided with Wireless video-signal transmission apparatus, this device carries out Signal transmissions with far-end wireless video signal receiver and is connected.
The operation principle of this setting pot is, near water inlet and below in one section of flow process, concentrate enhanced aeration, abundant disturbance water body and entrained sand grains thereof, reach wash-out object; Back segment on stream, water body turbulence intensity decays because not having aeration, for sand fallout in water creates favourable mechanical condition.When setting pot runs, aerate flux is identical with existing setting pot aerate flux, then the twice that the aerate flux in leading portion unit setting pot length brings up to traditional setting pot is even larger.
Advantage of the present utility model: 1, improve sand grains clearance; 2, aeration rate is easy to control; 3, through optimal design, the running distance inhaling sand purlin car can be shortened, be conducive to energy-conservation and reduce machine loss.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment: see accompanying drawing, leading portion concentrates the aerated grit chamber of aeration, is provided with the pond body 1 of long cuboid, and be provided with the sand catcher 5 that passes through total length at the bottom of pond, pond base slope is to sand catcher; Water inlet 3 is located at the side wall upper part of body one end, pond, and water inlet homonymy pool wall 2 bottom is provided with aeration tube 4, arranges a suction sand purlin car above the body of pond; It is characterized in that: described aeration tube is two row or multiple row aeration tube, arrange along setting pot length direction from setting pot water inlet end, aeration tube laterally or longitudinally arrangement, account for 6 length bottom the body of whole pond first three/mono-, Chi Tizhong, back segment do not establish aeration tube.Described aeration tube is Collapsible structure, and the aeration head that aeration tube is arranged is for convenience of the spiral rotary access node structure of dismounting.Be provided with online dissolved oxygen detection probe before, during and after in the body of pond, this probe carries out signal with the PLC controlling aeration air pump switch amount and is connected.Described suction sand purlin car is provided with timer, and this timer carries out timing open and close controlling with the run switch of purlin car and is connected.Camera established by described suction sand purlin car, and is provided with Wireless video-signal transmission apparatus, this device carries out Signal transmissions with far-end wireless video signal receiver and is connected.
