Description

A kind of instant siphon sludge drainage system for water treatment system
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of sludge drainage system of giving in water treatment, sewage disposal, relate in particular to siphon sludge drainage system.
Background technology
In water purification treatment system, the quality of sludge discharge effects directly has influence on the effluent quality of sedimentation basin (depositing reservoir).In sludge discharge way, mainly contain the modes such as perforation spoil disposal and siphon spoil disposal, although its middle punch sludge discharge way is cheap, but there is poor, the frequent obstruction of sludge discharge effects, need the shortcomings such as backwash, siphon spoil disposal is used widely because spoil disposal efficiency is high, inhale the advantages such as the heavy mud layer of not disturbance of mud, but has the shortcomings such as spoil disposal region is little, water consumption is large.Along with the appearance of rectangular sedimentation tank, researcher has been researched and developed siphon spoil disposal purlin car, but their keying operation is normally controlled with the time.These spoil disposal forms, owing to can not adapting to the variation of water turbidity, consequently occur that effluent quality deterioration, consumable dilutional hyponatremia, equipment move the phenomenons such as bad.Zhang Hongzhong in 2006 publishes an article on < < China water supply and drainage > >, and the transformation that adopts PLC to carry out automatic control to siphon spoil disposal purlin car has realized the automatic operating of siphon spoil disposal; 5 new policies in 2011 are published an article on < < water supply and drainage > >, employing is optimized transformation to positions such as sedimentation basin Inlet and outlet water end, water legs, in mud discharge car scraper plate bottom, set up film sealing, improving siphon suction inlet is flat suction inlet, optimize the modes such as operating condition of mud discharge car, eliminate the deposition in sedimentation basin, avoided the problem of sludge bulking floating.Improved system, in the situation that not increasing throwing alum amount, has reached the object that improves effluent quality of sedimentation tank.Above-mentioned improvement is for the rectangular sedimentation tank type of sleeve configuration, but for single sedimentation basin, as radical sedimentation basin or depositing reservoir, if adopt siphon sludge drainage system to carry out spoil disposal, generally be difficult to the mud in sludge bucket clear clean (depositing reservoir bottom A and B region as shown in Figure 1), the local siphon that reason is to approach pool wall less than and cause in pond spoil disposal not thorough, thereby easily deposition in pond, and then affect effluent quality.
Summary of the invention
The object of the present invention is to provide the instant siphon sludge drainage system for water treatment system that a kind of spoil disposal is thorough, water consumption is less.
The instant siphon sludge drainage system that the present invention proposes, to carry out Real-Time Monitoring by the sludge quantity at the bottom of the sedimentation basin of water treatment system or depositing reservoir pond, under the spoil disposal condition of setting, by siphon sludge drainage system, deposition in pond is discharged immediately, to ensure the normal operation of sedimentation basin or depositing reservoir.
Instant siphon sludge drainage system provided by the invention, is comprised of control device, sludge concentration meter, siphon mud discharging device; Wherein, siphon mud discharging device is comprised of siphon pipe, siphon accessory system, deflection cone; Siphon accessory system is comprised of pressure water source feedway, water sprayer, penstocks, exhaust tube and air admission valve; As shown in Figure 1, depositing reservoir (or sedimentation basin) 1 internal cause particles settling is divided into clarified supernatant 2 and slime layer 3, and depositing reservoir 1 exterior bottom is provided with water seal overflow launder 5; Described siphon pipe 4 one end are connected in depositing reservoir 1 bottom, and the other end is positioned at the water seal overflow launder 5 in depositing reservoir 1 outside, contain water siphon pipe 4 is formed to water seal in water seal overflow launder 5; Described deflection cone 14 is located at the place, bottom that siphon pipe 4 is positioned at depositing reservoir; Described sludge concentration meter 6 is arranged at the intersection of slime layer in depositing reservoir 13 and supernatant 2, for the concentration of at-once monitor slime layer; In described siphon accessory system, pressure water source feedway 8 is connected with water sprayer 9 by penstocks 11, auxiliary tube 10 upper end water receiving emitters 9, lower end passes in water seal overflow launder 5, exhaust tube 12 one end are connected with siphon pipe, another termination air admission valve 13, and air admission valve 13 is also connected with penstocks 11, and siphon accessory system is used to form siphon or stops siphon; 7 pairs of above-mentioned spoil disposal processes of control device are carried out Comprehensive Control.
The flow process of the instant siphon method based on above-mentioned instant siphonic system is: in depositing reservoir (sedimentation basin) 1, by sludge concentration meter (interface instrument) 6 Real-Time Monitoring slime layer concentration, when the sludge concentration of monitoring surpasses setting value C0, control device 7 is opened pressure water source feedway 8, make to be full of press water in penstocks 11, press water is through water sprayer 9 jet generation negative pressure, and the air in exhaust tube 12 suction siphon pipes 4, to form siphon; When siphon forms, 4 pairs of pool bottom sludges of siphon pipe produce swabbing action, guide functions because of deflection cone 14, syphonic water flow in depositing reservoir 4 bottoms and pool wall bottom (as A and B place) produce the volume effect of sweeping and the mud of precipitation siphoned away, the mud of depositing reservoir (sedimentation basin) 1 inner bottom part is expelled in water seal overflow launder 5; When bottom mud is after siphon pipe 4 is discharged, slime layer 3 concentration of sludge concentration meter (interface instrument) 6 Real-Time Monitorings reduce, when the sludge concentration of sludge concentration meter (interface instrument) 6 monitorings is less than setting value C1, control device 7 is opened air admission valve 13, air is entered in siphon pipe 4, thereby destruction siphon, siphon stops; After siphon stops, control device 7 cuts out 13, one spoil disposal operation processes of air admission valve and finishes.So instant siphon sludge drainage system continuously-running.
In the present invention, described sludge concentration meter (interface instrument) 6 can adopt ultrasonic wave densimeter or photoelectricity sludge interface instrument.
In the present invention, described pressure water source feedway 8 can adopt immersible pump or penstocks valve; Described air admission valve 13 can substitute with siphon timing bucket.
Compare with traditional siphon sludge drainage system, a kind of in good time siphon sludge drainage system provided by the invention, the mud (depositing reservoir bottom A and B region mud as shown in Figure 1) that depositing reservoir (sedimentation basin) bottom can be difficult for discharging is discharged, thereby spoil disposal is more thorough.The siphon spoil disposal time is controlled automatically by the online concentration feedback of slime layer, and the siphon spoil disposal time has been got rid of artificial disturbance, thereby spoil disposal water consumption is low, thereby has saved water resource.Meanwhile, siphon sludge drainage system of the present invention can keep mud, the water balance relation in water treatment building automatically, has greatly reduced the phenomenon that affects the disadvantage of water quality and spoil disposal obstruction because spoil disposal is improper.
