Description
Technical field
It the utility model is related to technical field of sewage, and in particular to municipal wastewater industry constant water level sequencing batch system is arranged
Mud system prevents the improvement system of siphon.
Background technology
Dalian Xia Jiahe sewage treatment plants use CWSBR techniques (Constant Waterlevel Sequencing
Batch Reactors), i.e. constant water level sequencing batch reactor.Its core technology has two：First, utilize water sail
(Hydrosail) reciprocating motion runs the change water level of conventional SBR to be changed to the operation of permanent water level, i.e., in single pond continuously into
Water, continuous effluent, periodically water-filling/stirring of completion SBR techniques, aeration, the overall process for precipitating, straining water.Second, permanent water level
The use of water decanter, reduces hydraulic loss, reduces energy consumption.It overcomes tradition on the basis of original SBR advantages are remained
SBR techniques intermittent water inflow, intermittent drainage, become the shortcomings that water level, permanent water level, continuous operation in whole sewage disposal process.I
The sewage treatment industry of state can not keep up with the fast development of economic situation all the time due to being developed slowly by financial strain,
Such case is especially prominent during China's city-building.And CWSBR techniques have that reduced investment, operating cost be low, water outlet water
The advantages that matter is good.
In CWSBR techniques, use residual sludge pump that unnecessary sludge is discharged into sludge for the sludge drainage system of capital equipment
In reservoir, original technique is conveyed by wired hose, and one end is connected in residual sludge pump, and one end is inserted into sludge storage pool
In.But find in actual operation, spoil disposal when sort run after, positioned at biological tank bottom of pond residual sludge pump stop work
Make, and one end that wired hose extend into sludge storage pool is highly higher than the one end being connected at biological tank bottom with residual sludge pump,
Due to liquid level difference, siphonage can be produced under the action of liquid pressure and atmospheric pressure, by the sludge in sludge storage pool
It is sucked back into biological tank.Thus, sludge drainage system is improved by research, adds a sewage treatment process spoil disposal and prevent
Siphonic system, and then avoid such case.
Utility model content
Traditional constant water level sequencing batch system, its sludge drainage system are run when straining water, dirty by residual sludge pump, wired hose
Mud reservoir forms.Follow-up Treatment of Sludge be by the sludge in sludge storage pool by sludge pump get to adjacent Treatment of Sludge factory into
Row processing.
It is to solve after spoil disposal process, since sludge is flow backwards caused by siphon the problem of, the utility model design is a kind of
The new anti-siphonic system of sewage treatment process spoil disposal, by sludge conveying assembly, sludge storage is emitted into by sludge from biological tank
Pond；The system comprises baffle-box and sludge conveying assembly；
The baffle-box includes the square pond body of inclined bottom surface, and the nearly biological tank side in baffle-box bottom surface is higher than another
Side；Above the side wall of the nearly biological tank one end of pond body, some side windows are offered, the baffle-box sidewall bottom opposite with side window, if
It is equipped with the sludge discharge pipe for being passed through sludge storage pool；
Sludge conveying assembly is connected by residual sludge pump with wired hose；The other end of the wired hose is led to by side window
Enter to buffer in box main body.
In the case of preferable, the buffering box wall, the lower section of side window, is provided with fixing bracket.
For side window described above, it can set multiple along the nearly biological tank side of baffle-box or be arranged to same with side wall
It is long.
In the case of preferable, the wired hose is passed through in baffle-box pond body and is supported by fixing bracket and fixed.
In the case of preferable, the wired hose outside diameter is less than side window opening.
In the case of preferable, the buffering box main body is stainless steel.
In the case of preferable, the baffle-box inclined bottom surface angle is horizontal by 5~30 °；Preferable angle is 15 °,
Such angle may advantageously facilitate flowing of the biological tank base sludge to sludge storage pool.
The diameter of the wired hose is less than the sidewall thickness of the sludge discharge pipe.
A diameter of 0.25m of the wired hose.
The sidewall thickness of the sludge discharge pipe is 0.5m.
Beneficial effect：
After the completion of improvement, sludge discharge pipeline is no longer extend under liquid level, but is directly exposed in air, coordinates baffle-box
Setting, effectively destroy the necessary condition of siphon generation, the siphonage after spoil disposal sequential occurs never again, can be with
By observing spoil disposal situation of the wired hose in the anti-siphonic system of sewage treatment process spoil disposal, whole sludge drainage system is got information about
Operation conditions.
Brief description of the drawings
The structure diagram of Fig. 1 anti-siphonic systems of sewage treatment process spoil disposal described in the utility model；
Wherein, 1. biological tank；11 liquid levels；2. sludge conveying assembly；21 residual sludge pumps；22 wired hoses；3. baffle-box；
31 baffle-box pond bodies；32 side windows；33 fixing brackets；34 sludge drains；4. sludge storage pool.
Embodiment
Following nonlimiting examples can make those of ordinary skill in the art that the utility model be more fully understood, but
The utility model is not limited in any way.
Embodiment 1
The sludge drainage system research of items selection Dalian Xia Jiahe sewage treatment plants constant water level sequencing batch system.Traditional perseverance water level
Batch-type system has many merits：Since the loss of flood peak reduces, energy consumption reduces, and operating cost is low；It is stable, reliable；Go out
Water excellent；Can denitrogenation, dephosphorization；Lness ratio of plant is low；With stronger capacity of resisting impact load；Sludge continued compression, sinks
