Description
Technical field
The present invention relates to a kind of in sewage treatment plant, the new technology of precipitation pool with peripheral, new technology relates in particular to a kind of periphery-transmission double-layer scraping and sucking machine of novel technique, in the application of precipitation pool with peripheral.
Background technology
Precipitation pool with peripheral uses the principle of the technical matters precipitation pool with peripheral operation of center transmission single-tube suction dredge to be usually:
From the mixed liquor of biochemical reaction tank, go out to precipitate the pool side point from Zhou Jinzhou and enter along the intake chamber of the continuous variation of pool side setting, apopore flows out through the intake chamber bottom.Current are by dash skirtboard water conservancy diversion, to the pond center position water outlet weir plate of evenly flowing through lentamente, enter effluent trough with the state of density current, flow out sedimentation basin.Sewage is able to separate with solid and purify.
Biologically active mud that biochemistry pool generated and the inorganic mud of coming in sewage are along journey sedimentation under the gravity effect.The inorganic inertia sludge settling speed that severe is big is fast, is deposited at the bottom of the pond in advance.The biochemical activity sludge settling speed that severe is little is slow, is deposited to inorganic inertia mud top.Biochemical activity mud enters dredging tube at the dredging tube of revolution operation under the effect of static-elevation difference, flow into the activated sludge tank of rotating cage bottom lock, by opening/shutting valve control, flows in the returned sludge groove.
Sink to the inorganic inertia mud at the bottom of the pond, under the effect of the cleaning shoe of revolution operation, scraped the inorganic inertia sludge sump at the bottom of the pond, enter sludge-tank, send into dehydration machine room dehydration and drying again as excess sludge.
Pond face scum silica frost casts aside the scum silica frost groove under the skimming plate effect of revolution running, flow into the scum silica frost pond, flows into sludge-tank through opening/shutting valve.
Old technical matters, the existing problems of single tube scraping and sucking machine are rotated at the center:
The center is rotated the single tube scraping and sucking machine and is adopted centre-driven, and rotating cage drives scraper arm, dredging tube rotates.Structurally there is following shortcoming:
I: the base bearing of rotating cage is worked in sludge water for a long time, inclement condition, easily water inlet.
Ii: the movable sealing that rotating cage bottom activated sludge tank and sedimentation basin bottom exist, in inertia mud environment, turn round for a long time, it is very fast to wear and tear, and easily loses efficacy, and the time out of service is long, and maintenance capacity is big.
Iii: the size of mud-suction hole on the dredging tube, pitch-row are calculated by hydraulic formula and there is gap in actual current, must have residual mud to exist, and the time one is long, and anaerobism clod come-up can cause water outlet SS to increase.
Iv: the single tube scraping and sucking machine adopts centre-driven, and torque is big, and power set require high, and the internal gear volume is big, and bearing requires sealing strict under water, device manufacturing process complexity, sedimentation basin input cost height.
V: waterborne parts are many in addition under water, and are strict by its underwater sealing, maintenance rate height after 2 or three years.
Invention new technology new technology content
Rotate the shortcoming of single tube scraping and sucking machine and the advantage of precipitation pool with peripheral at the center, invented the matching used new technology new technology of periphery-transmission double-layer scraping and sucking machine and precipitation pool with peripheral.The periphery-transmission double-layer scraping and sucking machine has the function of double layer separation mud, can give full play to the superiority of precipitation pool with peripheral; The capacity utilization height; Sedimentation effect is good; Spoil disposal concentration is big; Mud is fresh; Active strong.
The periphery-transmission double-layer scraping and sucking machine, full bridge structure; Be the suction mud mouth of inhaling activated sludge on one side; Dredging tube; Activated sludge tank; Be inertia mud cleaning shoe on one side.
Activated sludge enters activated sludge tank under the water-head effect, enter the top activated sludge tank again, is discharged outside the pond by center activated sludge pipe; Inertia mud concentrates on the inertia sludge-tank at center, pond under the effect of mud scraper plate, bury outside the sludge pipe discharge pond by giving.
Novel technique of the present invention has the following advantages:
The advantage of periphery-transmission double-layer scraping and sucking machine technology and technology:
I: dynamical system is at Chi Ding, under water without any device.
Ii: activated sludge tank moves to top and maintains static, and does not relate to underwater sealing.
Iii: dredging tube is inhaled the adjusting of mud mouth single valve, makes suction mud thorough.
Iv: the peripheral transmission arm of force is big, and torque is little.Power set require low.
V: rotate the single-tube suction dredge parts than the center and lack 30%, guaranteeing under equipment performance and the prerequisite of service life; The periphery-transmission double-layer scraping and sucking machine rotates single tube scraping and sucking machine cost than the center and descends more than 30%.
The characteristics of novel technique:
(1), after sedimentation basin circumferential water feed, peripheral effluent technical matters change; Stablized water flow; Surface loading is big; The volumetric efficiency height; Water outlet SS concentration is low.
(2), pool bottom sludge is stirred few, extract that sludge quantity is big, sludge concentration is high, improved the efficient of subsequent treatment.
3., the cross section of dredging tube and pipe are apart from the size of, Guan Jing, more meet the distribution of pool bottom sludge and the proterties of pool bottom sludge.
4., the activating plate of band activated sludge.
(5), energy-conservation, Operation and Maintenance is simple, process debugging is convenient.
(6), has electric current and cross to turn round and refuse duplicate protection.
(7), can reduce the whole investment of this equipment more than 30%.
