Below in conjunction with drawings and Examples, this utility model is described in detail.
Detailed description of the invention
Fig. 1-3 illustrates a kind of Multilevel A/O Technology biological tank scum silica frost removal device and application thereof, and described biological tank includes by solid
Determining anaerobic zone I, anoxic zone II and aerobic zone III that partition wall 7 separates, described anaerobic zone I, anoxic zone II are by being located at each self-retaining
Exhalant canal 6 on partition wall 7 is respectively communicated with aerobic zone III, and the Multilevel A/O Technology biological tank scum silica frost provided due to this utility model goes
Except the device application in biological tank anaerobic zone I, anoxic zone II is identical, therefore, Fig. 1, Fig. 2 have employed simple schematic diagram.
Of the present utility model be characterised by described stationary partition 7 be top along the not stationary partition under water in water, in construction,
This is less than corresponding anaerobic zone or anoxic zone liquid level 30-40cm in edge, stationary partition top under water.
The stationary partition under water of anaerobic zone I and side, anoxic zone II is arranged along the weir plate that stationary partition two ends are fixedly mounted with under water
Slide rail 5 adjustable weir plate 4 moving up and down, it is horizontal linear shape that waterside is crossed at the top of described adjustable weir plate, and adjustable weir plate 4 exists
The vertical downward formation in the position of the exhalant canal 6 of stationary partition 7 under water described in correspondence intercepts water plate 41, in practice of construction, adjustable
The area of the intercepter plate 41 of weir plate 4 accounts for the 20%-30% of described exhalant canal cross-sectional area.
Adjustable weir plate 4 two ends are hinged with vertical screw rod 2 lower end by connecting shaft 3 respectively, and described vertical screw rod 2 upper end is even
Connecing linear screw motor 1, two linear screw motors 1 are all connected to control its controller 10 synchronizing start and stop.See Fig. 3, this reality
Execute in example, 4 liang of vertex angle parts of adjustable weir plate and vertically screw rod 2 bottom be all connected mounting ring 11, connecting shaft 3 have employed bolt and passes
Two mounting ring 11 nut lockings, it is achieved adjustable weir plate 4 is hinged with vertical screw rod 2.It is articulated and connected and makes the upper of adjustable weir plate 4
Rise to decline and improve flexibility.Controller 10 can use PLC programmable controller, also can use based on the time relay
Control circuit realizes the synchronization on off control to two linear screw motors 1.Thus control adjustable weir plate 4 and steadily lift.Slagging-off
Adjustable weir plate 4 under state, it flushes along height with stationary partition under water；Adjustable weir plate under non-slagging-off state, edge on it
Exceeding anaerobic zone or the anoxic zone liquid level of correspondence, in actual application, the upper edge of the adjustable weir plate under non-slagging-off state exceeds correspondence
Anaerobic zone or anoxic zone liquid level 5-10cm.
Biological tank run time, treatment sewage enters biological tank anaerobic zone I, anoxic zone II from water inlet 8, due to scum silica frost,
Mud scum is as what AO process operation was gradually piled up, under non-slagging-off state, controls linear screw motor 1 by controller 10 inverse
Hour hands rotate, and the upper edge that vertical screw rod 2 is exercised adjustable weir plate 4 exceeds the liquid level 9 of anaerobic zone I or anoxic zone II, and being adjusted to can
The upper edge of weir transfer plate exceeds anaerobic zone or the anoxic zone liquid level 5-10cm of correspondence.At this moment, the function of adjustable weir plate 4 is equivalent to increase
The height of stationary partition under water, thus stop that the fluid of anaerobic zone I or anoxic zone II flows into aerobic zone III.Along with AO technique is transported
OK, scum silica frost, mud scum are piled up, and now start slagging-off operation, under controller 10 controls, control linear screw motor 1 dextrorotation
Turning, vertical screw rod is exercised for 2 times and is flushed with edge, the top of stationary partition 7 under water along height on adjustable weir plate 4, and now, liquid level is higher than under water
The edge, top of stationary partition, simultaneously as the descending water outlet section making exhalant canal 6 of the plate 41 that intercepts water diminishes, surface flow rate of water flow carries
Rising, scum silica frost progressively flows out to follow-up process section aerobic zone III, is ultimately discharged into sedimentation tank and carries out the separation removal of scum silica frost.
It can be seen that this utility model utilizes pulling flow type biological tank fluidised form principle to carry out dynamic baffle design, by detesting
Arrange on the stationary partition under water of oxygen district and side, anoxic zone along the weir plate slide rail 41 that stationary partition two ends are fixedly mounted with under water can on move down
Dynamic adjustable weir plate 4, makes the height of stationary partition under water become adjustable, thus solves biological tank in Multilevel A/O Technology and accumulate floating
The problem of slag.During work, the linear screw motor 1 at adjustable weir plate two ends control its height promoting and declining；According to scum silica frost
Accumulation time, set linear screw motor the interval time, thus can realize full-automatic unmanned control on duty.
This utility model, can carry out non-stop production reformation on existing Process ba-sis, simple for structure, is suitable to multistage
AO sewage treatment process field is promoted.
Any pro forma restriction not made by structure of the present utility model, shape and material by above content.Every foundation
Any simple modification, equivalent variations and the modification that above example is made by technical spirit of the present utility model, all still falls within this
In the range of utility model technical scheme.
