Portion.
Due to 100 unique structure design of bottom pyramidal flocculation sedimentation tank make its for meet precipitation need depth design compared with
Greatly, therefore bottom hydraulic pressure is larger, then inner tube 122 is sticked in the inner wall of heavy bucket 120 by the pressure that inner tube 122 is born with regard to larger
Inner tube 122 can be effectively avoided to bear high pressure for a long time and damage.
Further, the diameter of sludge pipe 121 is greater than or equal to 200mm.Sludge viscosity is higher, is bound to during spoil disposal
Understand the inner wall that some sludge is adhered to sludge pipe 121, sludge pipe is likely to result in if the diameter of sludge pipe 121 is too small
121 blocking can ensure that spoil disposal is unobstructed when the diameter of sludge pipe 121 is greater than or equal to 200mm.
Further, bottom pyramidal flocculation sedimentation tank 100 further includes sludge pump 170, the connection of 170 sludge pipe 121 of sludge pump.
Usual sludge is periodically discharged by influent pressure, since 100 unique structure design of bottom pyramidal flocculation sedimentation tank makes it
Projected depth is deeper, therefore spoil disposal is easy.If desired more rapidly spoil disposal then can carry out spoil disposal by starting sludge pump 170.
Further, bottom pyramidal flocculation sedimentation tank 100 further includes blender 160, and the bottom end of blender 160 is located at pond sheet
In body 110.It is had been added into water when workshop section of the flocculant before bottom pyramidal flocculation sedimentation tank 100, blender 160 is set
Be in order to ensure enter bottom pyramidal flocculation sedimentation tank 100 in water and flocculant it is more fully mixed.
As shown in Figure 1 and Figure 4, flocculation sedimentation system 10 includes straight arranging mixer 200,300 and of star fin flocculation basin
Multiple bottom pyramidal flocculation sedimentation tanks 100, straight arranging mixer 200 are connected to star fin flocculation basin 300, the flocculation of star fin
Pond 300 is connected to multiple bottom pyramidal flocculation sedimentation tanks 100, and partition board 311 and fin frame are provided in star fin flocculation basin 300
312, partition board 311 is arranged along water (flow) direction, is provided with fin 313 on fin frame 312, fin 313 is perpendicular to water (flow) direction.
During the work time, coagulant PAC is added from the dosing mouth of straight arranging mixer 200, due to straight arranging mixer
200 introduce the micro- principles of hydrodynamics of fluid to control mixing microprocess and Macroscopic Process, under identical head loss, greatly
Its mixed effect is improved greatly so that coagulant is more fully mixed with sewage.
Flocculation aid PAM is added into star fin flocculation basin 300, since the design of partition board 311 and fin 313 makes flow
High spectrum is generated when flowing through partition board 311 and fin 313 to be vortexed, increases particles collision number, improves effective collision rate, star fin
Flocculation basin 300 comes into full contact with the particle in water for medicament and provides good micro- hydrodynamic conditions, can be produced in flocculation basin end
The raw closely knit alumina blossom particles easily precipitated.Partition board 311 and fin 313 in star fin flocculation basin 300 it is easy for installation so that
Sewage flocculation effect is good, and low energy consumption, and flocculation time is short.
The Unique physical design of bottom pyramidal flocculation sedimentation tank 100 can weaken settling apparatus lower part one in sedimentation basin and position
The large eddy intensity in flow is set, the pulsation of settling zone flow is reduced.After flow is in entrance equipment, the particularity of this structure
It is inscribed in equipment to improve alumina blossom particles during constantly changing velocity flow pattern for the process that contact flocculation can further be controlled
The probability hit is touched, each other absorption connection, only scale and density are enough to overcome the alumen ustum of the correlative factors such as flow jacking force
Grain can just sink, and the alumina blossom particles of nominal particle size are constantly adsorbed during continuous sinking, until being detached from settling apparatus.Work as alum
When colored gravity maintains dynamic equilibrium with flow jacking force and dependent interaction power, contact flocculation and sedimentation effect is more enhanced, is being set
Standby interior certain position forms closely knit, strong shock resistance, automatically updated and short update cycle dynamic suspension slime layer, this
Sample makes the suspension slime layer moment keep very strong filtering, absorption, pollutant carrying capacity, sedimentation effect more preferable.
Flocculation sedimentation system 10 is due to including straight arranging mixer 200, star fin flocculation basin 300 and multiple bottom pyramidals
Flocculation sedimentation tank 100, above-mentioned three's mutual cooperation effect, enables to have preferable flocculation sediment through flocculation sedimentation system 10
Ability, the sewage effluent quality after being processed are more preferable.
Further, flocculation sedimentation system 10 further includes pH regulating reservoirs 400, pH regulating reservoirs 400 and straight arranging mixer 200
Connection.When handling sourer sewage, in order to make flocculating effect more preferably need sewage pH being adjusted to alkalinity, therefore can will be dirty
Water, which is adjusted to be passed through again in straight arranging mixer 200 after suitable pH in pH regulating reservoirs 400, adds flocculant.
Further, pH regulating reservoirs 400 are also equipped with blender 160.Setting blender 160 enables pH regulating agents more
It is sufficiently mixed soon with sewage so that the pH of sewage faster reaches in suitable range.
The utility model additionally provides a kind of sewage disposal system 1, which provides including the utility model
Flocculation sedimentation system 10 and filter press 2, filter press 2 be connected to sludge pipe 121, from sludge pipe 121 be discharged sludge through press filtration
