Description
Technical field
The present invention is the improvement to water treatment clarifying plant, particularly relate to a kind ofly can realize clarifying in same clarifying plant simultaneously, the water clarifying device of concentrated, precipitation, filtering function.
Background technology
Water treatment clarification is mainly used in as surface water, high turbidity raw sewage, and the sand water of sewage disposal and Treatment for Reuse etc. is separated and water clarification process, object be make silt particle, suspended substance is separated with water, makes process water obtain High-speed clarification.For realizing High-speed clarification, mixing, flocculation reaction and depositing technology are combined in the accelerator in a device or pond by the more employing of prior art, and basic structure as shown in Figure 1.Basic structure and working process are: separated by a loudspeaker toroidal membrane 1 in treating pond central region, it is mechanical stirring coagulating district 3 in the middle part of hydraucone, bottom is precipitate and separate, Gua Ni district 2, hydraucone upper periphery is that inclined tube/swash plate accelerates depositing separation area 7, centered by top, (inside depositing separation area) is current stabilization water distributing area 5, and is vertically disposed with two promoted stirrers that power drives respectively 8 and biased driving mud scraper 6.Clarifying treatment water inlet enters coagulating district 3 by middle part annular water distribution mouth, makes coagulating, increase and wad a quilt with cotton and macrobead silt particle is sunk down at the bottom of conical tank naturally, discharged by mud scraper 6 Gua Xiang center mud discharging mouth under whipping appts hoisting type blade 4 stirs; Lift at hoisting type paddle wheel through preliminary silt particle Separation of Water, after water rises and enters central upper portion current stabilization water distributing area 5 current stabilization in the middle part of impeller, again along under loudspeaker toroidal membrane 1 lateral, then upwelling enters inclined tube/swash plate disengaging zone 7, carry out muddy water secondary separation, clarification and effluent enters end face water leg and discharges, and secondary sedimentation silt particle is by entering at the bottom of conical tank bottom loudspeaker toroidal membrane 1.Paddle wheel (hoisting type blade 4) is promoted up and down by timing and effective coagulating effect precipitated is guaranteed in speed governing, but in actually operating, operator are for reducing workload, often adopt paddle wheel to customize and run in middle part constant speed, cause newly entering water inabundant through coagulating, just promote state impeller by half and enter current stabilization water distributing area, top 5, not only reduce the separation of the follow-up suspended substance of flocculation reaction influential effect, and make to enter silt particle in top water, suspended substance amount increases, affect equally later separation process and process outlet effect.In addition, adopt mechanical stirring to accelerate mixed flocculation, not only power consumption is comparatively large, and it is much bigger that usual mechanical stirring power will comparatively scrape mud power, uninterruptedly runs continuously, and power consumption is large, and mechanical loss is also large, also add and runs and maintenance cost;
And chemical feeding quantity is comparatively large, is more the increase in processing cost; Mechanical stirring must have enough areas, and precipitate and separate then needs water current stabilization geo-stationary, the buffering current stabilization district taking larger area must be set after vigorous stirring coagulating, take suitable pond and hold and be difficult to make full use of settling pond volume other functional zone are set.Besides, objectively clarifying treatment water retention time is short, meets the big yields such as the rain that exposes to the sun and impacts, for want of accelerate precipitate and separate ability, and process water outlet does not reach requirement.
In addition, prior art clarifying plant, only has the clarification being separated silt particle, suspended substance, can only for separating of silt particle and relatively large suspended substance, water outlet SS is required higher also to need through subsequent filter process, such as Chinese patent CN1990397 steel iron wastewater coagulating sedimentation and filtration treatment system, coagulation and pH regulator pond after setting up after the high dense settling pond of collection reaction, clarification, simmer down to one, be provided with filtering basin afterwards.Because clarification and effluent is without pressure, follow-up filtration is set separately, not only needs to set up intermediate pool, and pump need be increased promote, discharge muddy water after precipitation, clarification and need set up separately sludge thickener and concentrated mud scraper.Not only make treatment scheme elongated, floor space increases, and pipeline increases, and one-time investment expense is large, and run power consumption and increase, working cost is high.In addition, pump adherence pressure also causes in backwash process, and head loss is comparatively large, causes and processes water waste greatly.
For improving clarifying plant treatment effect and ability, people carry out multiple improvement to above-mentioned mechanical stirring clarifying plant, such as.
Chinese patent CN1715200 Circulation clarifying pool, by arranging reaction chamber inside and outside tube-in-tube structure in the middle part of clarification pool structure, and connect the ejector of interior reaction chamber, spraying to interior reaction chamber realizes Hydraulic Circulation coagulation at a high speed to suck body refuse by ejector, reach omission mechanical stirring, and provide coagulation to cushion by inside and outside sleeve interlayer, omit and current stabilization water distributing area is set separately, increase coagulating district.But still need configurating filtered process to requiring that high water outlet is follow-up.
Disclosed in Chinese patent CN2528764, water revolves clarification air flotation pool, by being provided with grid at hybrid reaction zone center cylinder water inlet pipe place, flow deflector is provided with outside hybrid reaction zone center cylinder, guiding region III is formed between flow deflector and central tube, and be separated out contact zone of dissolved air flotation and flotation separation zone on top, disengaging zone by air flotation pool base plate, thus by enhanced coagulation, clarification, air-float technology comprehensively in structures.Although can be separated wherein suspended substance further by air supporting, air supporting to remove minute impurities, namely do not reach filter effect, and therefore water outlet still needs to carry out filtration treatment; In addition, increase air supporting and be more the increase in operation power consumption.
Applicant's Chinese patent CN200820215488.X mechanical accelerating purifying pool, adopts and to be stirred by adjacent machine and flap reaction is composed in series rectangle coagulation reaction tank, and adjacently with square settling pond to be arranged in series.Applicant's Chinese patent CN200810242781.X quick-speed clarification tank, clarification pool wall top arrange around coagulating groove, the built-in coagulating room that vertical alternate waved plate is formed, settling pond middle and lower part alternate " people " word of employing or " W " structure eddy current flocculation reaction device of falling.Equally just improve clarifying effect, do not solve the filtration problem of clarification and effluent.
Thus, above-mentioned prior art mostly relates to be improved coagulation, omission mechanical stirring is improved, but basic function still uniquely only has precipitate and separate clarification, precipitation can only be reached and remove silt particle and larger suspended substance in water, but this is often still inadequate in clarification of water process, for requiring that follow-up still need of higher water outlet arranges filtering function separately, and the rearmounted deficiency arranging filtrating area separately still exists.Still have the place being worth improving.
