Description
Technical field
This utility model relates to a kind of vertical sedimentation basin, belongs to sewage-treatment plant technical field.
Background technology
Vertical sedimentation basin, also known as vertical sedimentation basin, is the sedimentation tank that in pond, waste water vertically flows.Cell body planar graph is circular or square, water is entered (in pipe, flow velocity should be less than 30mm/s) in pond from top to bottom by the water inlet pipe being located at center, pond, pipe is divided into umbrella-shaped baffle and is made waste water be uniformly distributed the whole cross-section of river of tailing edge in pond slowly to rise and (be generally 0.5-0.7mm/s for sanitary sewage, sedimentation time uses 1-1.5h), suspended substance sedimentation enters pond base cone shape and sinks in bucket, and primary water flows out from pond surrounding peripherally downflow weir.
In vertical sedimentation basin, water (flow) direction is in opposite direction with granule precipitation, its speed of damming is equal with the current rate of climb, the rate of climb will be suspended in mixed liquor one layer of superposed layer of formation equal to the granule of sedimentation velocity, above-mentioned granule is intercepted and filters, thus the efficiency of vertical sedimentation basin is higher than rectangular sedimentation tank.Tradition vertical sedimentation basin is big, uneven due to Chi Nei center water distribution flow velocity, directly affects sedimentation effect, makes actual motion effect have a greatly reduced quality, particularly the biggest when footpath, pond, affects the most obvious.This is to limit tradition footpath, vertical sedimentation basin pond to do big main cause, and for making even water distribution in pond, footpath, pond is unsuitable excessive, typically can only accomplish 4～7m, and volume is little, the sewage disposal that the scale that may be only available for is less.
Along with socioeconomic high speed development, people's living standard improves constantly, and town and country water consumption is gradually increased, and pollutes increasingly severe, and what discharging standards required in addition improves constantly, and the advanced treating of sewage and recycling increasingly come into one's own.Original vertical sedimentation basin only has 30m3/ h treating capacity, along with the expansion of coke oven production capacity, biochemical system water yield has reached 50 m3/ h, original vertical sedimentation basin is less than normal due to diameter, and the float in system water outlet, due to sedimentation time and the deficiency of settling height, can not get effectively removing, and the float causing system water outlet is higher, affects COD index.
Utility model content
This utility model technical issues that need to address are to provide a kind of vertical sedimentation basin, improve sedimentation time and settling height, the effective float removed in system water outlet, make COD discharge index meet demand.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of vertical sedimentation basin, including cell body, the middle and upper part of cell body be formed around some V-type inclined tube fillers, intilted angle r of V-type inclined tube filler is 45～75 °, distance between adjacent V-type inclined tube filler is 50～100mm, bottom and the top of V-type inclined tube filler are equipped with the inclined-tube support being fixed on cell body inner surface, and the inner surface of cell body and the outer surface of inclined-tube support are equipped with anti-corrosion layer, and the bottom of cell body is provided with sludge stirring device.
Further improvement is that of technical solutions of the utility model: cell body uses stainless steel, and cell body is circular or square.
Further improvement is that of technical solutions of the utility model: cell body outer surface is additionally provided with the transparent height displaying instrument that connect internal with cell body.
Further improvement is that of technical solutions of the utility model: anti-corrosion layer is zinc-containing alloy coating or corrosion-resistant carbon fibre cloth layer or epoxy coal tar coating, and anti-corrosion layer thickness is 5～15mm.
Further improvement is that of technical solutions of the utility model: each V-type inclined tube filler is connected the end of with by the equicrural ladder plate of two same specifications setting up and down and forms.
Further improvement is that of technical solutions of the utility model: V-type inclined tube filler material is polypropylene, polrvinyl chloride or fiberglass.
Further improvement is that of technical solutions of the utility model: sludge stirring device includes drive rod and the stirring vane being fixed on drive rod, and drive rod is connected with the driving motor at cell body top.
Owing to have employed technique scheme, the technological progress that this utility model obtains is: water distribution uniformity and tube settling one, takes up an area few, and sedimentation effect is good.The pond utilizing original vertical sedimentation basin holds and structure, inclined tube filler is installed additional in the middle and upper part in pond, mixed reaction pond water outlet containing float is by entering to below filler in the middle part of sedimentation tank, float bulky grain part sedimentation under gravity, part settles more difficult float and is intercepted by inclined tube filler, extends the sedimentation time and has obtained further precipitation, and water outlet is through the filtration of filler, make float be efficiently separated, increase the treating capacity of original sedimentation tank.
Simultaneously it is additionally arranged at the bottom sludge stirring device at sedimentation tank, makes pool bottom sludge be assembled and be evacuated to sludge concentration tank filter pressing, effectively prevent pool bottom sludge anaerobism and float, it is ensured that the COD index of system water outlet.
This utility model wetted perimeter is big, hydraulic radius is little, laminar condition is good, granule sedimentation is not drained off by wadding and disturbs, safe operation can process in the high concentrtion of 50～100 kilogram/cubic metre silt contents, disposal ability is 2～3 times of 3～5 times of rectangular sedimentation tank, accelerating purifying pool and plusator, and effluent quality is good.
This utility model reasonable in design, even water distribution, streamflow regime is stable, sedimentation effect is good, does not has short circuit and dies, and the capacity utilization of sedimentation tank is high, and there is higher surface loading, breach the restriction that tradition footpath, vertical sedimentation basin pond is little, can make, the colleague ensureing that sedimentation effect is good, the sedimentation tank being relatively large in diameter.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
As shown in Figure 1, a kind of vertical sedimentation basin, including the cell body 1 that stainless steel is rounded or square, the V-type inclined tube filler 2 being formed around some polypropylene, polrvinyl chloride or glass steel material of the middle and upper part of cell body 1, each V-type inclined tube filler 2 by the equicrural ladder plate ibid end of two same specifications setting up and down or forms with going to the bottom to connect.Intilted angle r of V-type inclined tube filler 2 is 45～75 °, preferably 50 °, and the distance between adjacent V-type inclined tube filler 2 is 50～100mm, preferably 80mm.Each V-type inclined tube filler 2 longitudinal length is 1～2m, preferably 1.5m.
The bottom of V-type inclined tube filler 2 and top are equipped with the inclined-tube support 3 being fixed on cell body 1 inner surface, are used for supporting V-type inclined tube filler 2.The inner surface of cell body 1 and the outer surface of inclined-tube support 3 are equipped with anti-corrosion layer 4, strengthen cell body 1 and the service life of inclined-tube support 3, the anti-corrosion layer 4 of cell body 1 and inclined-tube support 3 is zinc-containing alloy coating or corrosion-resistant carbon fibre cloth layer or epoxy coal tar coating, and the anti-corrosion layer material of the two may be the same or different；Anti-corrosion layer 4 thickness is 5～15mm, and inner surface anti-corrosion layer 4 thickness such as cell body 1 is 5 mm, and anti-corrosion layer 4 thickness of the outer surface of inclined-tube support 3 is 15 mm, and the two thickness can be identical certainly.
