Abstract
The present invention relates to a kind of flat wound membrane of automatic cleaning water (cloth) sedimentation basins, and the film rolling device including horizontal transport sludge desilts the scraper plate of function with the vertical partition for the parallel water (flow) direction for playing flow stabilizing function and self-cleaning.Device forms the area Liang Ge in sedimentation basin, and region locating for flat membrane (cloth) and vertical partition is mud-water separating area, sinks mud face for horizontal plane, i.e. scraper plate region is sludge secondary settlement area between pool wall on the outside of the roll shaft of both ends.Achieve the purpose that control on film sludge quantity and further control sludge movement speed and state by the translational velocity of controlled level film (cloth).The advantage of the invention is that deposition efficiency is high, water stabilization, production is simple, and construction cost is low, and maintenance is simple, is truly realized shallow pool theory target.
Description
Technical field
The present invention relates to a kind of sedimentation pond for water treatment more particularly to the heavy mud faces of sedimentation basin, mud-water separation path and anti-turbulent flow
Device.
Background technique
The current general inclined plate of water treatment field (pipe) is although the ponds type such as sedimentation basin, novel horizontal pipe sedimentation basin is heavy in advection
Have improvement on the basis of the pond of shallow lake, but still without really solving mud-water separation efficiency, be unable to control sludge collect state and
Speed, these designs have the following problems and disadvantage: sludge slides on heavy mud face before arrival bottom of pond fully relies on free gravity
Accelerate to slide, accumulates generation mud avalanche disturbance water body in the slideway later period or excessive velocities aggravate turbulent flow, lead to mud-water separation path
Interference effect effluent quality of sedimentation tank is stablized repeatedly；The heavy all inclined-planes in mud face, all with horizontal plane there are inclination angle, it is effectively heavy to reduce
Shallow lake area reduces deposition efficiency, and it is weak to adapt to water quality and quantity fluctuation ability；The easy blocking plate of long-play deposition (pipe) bottom,
The cycle of operation is shortened, operation and maintenance difficulty is increased；Processing and fabricating is complicated, and dismounting is not flexible, and local damage needs integral replacing,
Increase daily maintenance expense；Occupied area is larger, and capital cost is high；It needs periodically to be vented cleaning, self water consumption is big.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of flat wound membrane of automatic cleaning water (cloth) sedimentation basin, purpose exists
In providing a kind of manufacture and be easy, old cheap, and maintenance is simple, the device for effectively separating that mud, water are independent of each other after particle sedimentation.
To achieve the above object, the flat wound membrane of automatic cleaning water provided by the invention (cloth) sedimentation basin is achieved in that
Multiple-layer horizontal wound membrane (cloth) device is loaded in sedimentation basin, the heavy mud face formed on every layer of horizontal wound membrane (cloth) is horizontal plane, dress
It sets and space in pond is divided into two regions, the vertical direction of film is mud-water separating area, and the both ends of film are sludge secondary settlement area.It is logical
The periodic reverse motion of wound membrane in the horizontal direction is crossed, the sludge transfer deposited on this tunic is opposing stationary to device two sides
Vertical Settlement area, adjusting wound membrane speed can control sludge residence time on film, further controls and mud layer state and collects
Speed.In Disengagement zone, floccule body particle vertical sedimentation in flat membrane after it is horizontal at the uniform velocity slow on Transverse to the flow direction with film
Slow mobile, muddy water is not interfere with each other, and each interlayer sludge is uniformly distributed over time and space does not generate local retention accumulation.From point
Bottom of pond sludge discharging area is sunk to naturally in the static decanting zone of water flow relative closure from the sludge in area, and secondary disturb is not generated to interlayer clear water
It is dynamic.According to design, multilayer film rolling device is can be set in selected parameter, can be set along water (flow) direction and Transverse to the flow direction
The multiple groups film rolling device of different length different in width.Two sides roll shaft winds the film (cloth) of certain length in advance.The rotation of device is dynamic
Power can directly be provided by underwater motor can also by machine driving by being provided on the water surface, by acquisition control speed, position,
The signals such as period realize automatic operating.
In another aspect of the present invention, it is arranged below in the bracket of every tunic (cloth) along the equidistant flat of water (flow) direction
Row water conservancy diversion partition, can reduce hydraulic radius, substantially reduce Reynolds number, and disturbance rejection is strong, can preferably stabilizing water quality.
It is equipped with cleaning shoe in front of the both ends roll shaft of device, the blocked up mud film adhered on film can be removed, do not need to be vented
Whole pond water can be cleaned.
Since the present invention is using the multilayer wound membrane (cloth) moved horizontally and the structure of several partitions of parallel water (flow) direction, thus
It is available following the utility model has the advantages that 1, deposition efficiency is higher.At present water treatment field application inclined tube (plate), folded plate corrugated plating,
All with horizontal plane there are certain inclination angle, wound membrane of the invention (cloth) angle with horizontal plane is in the heavy mud face of horizontal tube sedimentation basin type
Zero, mud face is sunk for horizontal plane, and absolutely, according to water and water quality requirement difference, interfloor distance is any for desilting area utilization rate
Setting, spacing smaller sedimentation basin residence time are shorter.To be truly realized shallow pool theory target.2, water quality stabilizing after sinking.
Distribution of sludge is relatively uniform in each layer wound membrane, and each interlayer sludge is independent of each other.Single layer wound membrane Distribution of sludge along moving direction
Be it is uniform, can accurately control sludge quantity on film, sludge will not be generated with time duration local accumulation and then blocking device,
The cross-section of river is reduced, mud avalanche disturbance water body will not be more generated, sludge state peace shifting speed is controllable in Disengagement zone, and sludge state is steady
Calmly, mud-water separation is irreversible, and plant failure can realize automatic operating by the timely alarm treatment of monitoring system.From
And thoroughly avoid the landing of sludge present in the sedimentation basins such as the inclined tube (plate), lateral flow ripple inclined plate, horizontal tube of current application
The turbulence prediction generated in the process influences the problem of water quality and bottom of device region is easy blocking problem not easy to clean.3, it saves
About personal water.Water needs all emptyings when inclined plate (pipe) sedimentation basin periodic purge, and self water consumption is big, and increases at sludge
Reason system short term.The present invention need not be vented by the cleaning shoe of two sides can remove the sludge adhered on film, avoid
It periodically cleans impact to sludge treating system with water, saves self water consumption and can long-term continuous operation.4, processing and fabricating is simple,
It is easy to maintenance, it can be replaced with single layer, modular repair, maintenance expense is low.5, sedimentation basin can be increased substantially for reconstruction project
Effluent quality and water reduce self water consumption and update cost.6, space occupied, Economization on land can be reduced for new construction
Resource is reducingd the construction costs.
