Description
Technical field
The utility model belongs to sewage treatment field, and the water quality being related in the reaction tank and horizontal sedimentation tank of water treatment plant is net
Change, and in particular to a kind of to handle the full-automatic control system to purify water in earth's surface water purifying plant reaction tank and horizontal sedimentation tank.
Background technology
The water treatment technology of present earth's surface water purifying plant is increasingly advanced, this also just requires the automation control of water treatment plant simultaneously
System is horizontal higher and higher.And the water source that earth's surface water factory introduces, generally have and contains part silt particle（Due to being its mud for containing of surface water
Sand amount changes with the variation in season）, but the feature that the organic pollution that contains is relatively low, therefore main treatment process is to remove
Suspended matter in raw water, generally without the advanced treating of water, common process process is using folded plate flocculation, advection sedimentation, V-type filter
Pond filtering, four processing stages of chlorination.It is the preceding part processing stage of flocculation and precipitation as earth's surface water purifying plant, main
Purpose is exactly so that medicament is adequately mixed with water by adding flocculant in mixed reaction pond, remove the electricity of colloid surface
Lotus creates hydraulics, so that colloidal solid is mutually collided cohesion, form big particle, in favor of sedimentation, realizes solid- liquid separation,
The part processing stage completes in prime mixed reaction pond, while the sludge quantity of the stage precipitation is maximum, and can drop significantly
Turbidity in low raw water, the sense index of the water quality such as coloration.Sedimentation basin is exactly to utilize shallow pool theory, increases desilting area, is shortened
Settling height improves sedimentation effect, and polyacrylamide is used usually as flocculation aid, plays absorption bridge beam action, further
Suspended particle in raw water is settled to form sludge removing, the clear water liquid on top is flowed out by water outlet.Due to treatment process
Different with the architectural design of processing pond, the sludge quantity that reaction tank is formed is from prime mixed reaction pond to the big of final stage mixed reaction pond
It is small to successively decrease distribution at step.Several sludge pipes are set in prime mixed reaction pond and horizontal sedimentation tank, on every sludge pipe
If dewatered sludge hole is distributed with, the sludge to settle down enters sludge pipe by the pressure of upper water by sludge hole, finally by
Waste water containing sludge is discharged for the unlatching of motor-driven valve.Since the sludge quantity of final stage mixed reaction pond is less, walking is generally taken
Suction dredge inhales mud in walking, and the sludge of the part bottom of pond can be discharged outside pond.
The spoil disposal motor-driven valve 3 on every sludge pipe arranged in prime mixed reaction pond configures 1 control cabinet, has above
Switch button, usually by operations staff to execute-in-place control cabinet come the artificial sludge discharge work for carrying out sludge pipe, such mode
Though sludge discharge work can be completed, have the disadvantages that：There is artificial spoil disposal randomness and randomness, operating personnel can arbitrarily control
It makes every sludge pipe and carries out spoil disposal, the phenomenon that sludge pipe repeats spoil disposal and omits in printing often occur；Secondly, when the spoil disposal of artificial spoil disposal
Between and the bad control of sludge discharging period, often result in water, medicament waste or influence sludge formation and sedimentation；
Final stage mixed reaction pond is due to using manual control walking suction dredge, it may have following disadvantage：Manual control row
The operation of the motor and dredge pump of formula suction dredge is walked, there is randomness, often results in water, the waste of medicament or influence sludge
It is formed and is settled；Secondly, movable motor and dredge pump are connected by sliding cable with control host, and not only use cost is high, and
And failure rate takes place frequently；
Horizontal sedimentation tank：Since flocculation and precipitate phase part carry, water treatment plant is main to remove suspended matter in raw water
Work, if cannot exclude to will have a direct impact on purifying water effect in time.And handle sludge pipe motor-driven valve and walking suction dredge well
Control becomes the key link of the phase process.
