Embodiment
As shown in Figure 1, high fluorinated water purifying treatment integrated apparatus of the present utility model, mainly comprise reaction tank, perforation water distributing pipe 1, flocculating chamber 2, sludge settling district 3, sloping plate deposition layer 4, Filtration Adsorption layer 5, effluent trough 6, perforated sludge discharge pipe 7, gas back-flushing pipe 8 and back flushing rising pipe 9.
As shown in Figure 1, high fluorinated water purifying treatment integrated apparatus of the present utility model, mainly comprises reaction tank, is disposed with sludge settling district 3, sloping plate deposition floor 4 and Filtration Adsorption floor 5 in reaction tank from the bottom to top.
Be provided with flocculating chamber 2 in sludge settling district 3, in flocculating chamber 2, be provided with water distributing pipe 1.Water distributing pipe 1 surrounds by flocculating chamber 2 along its length, is surrounded by top board and biside plate, leaves water outlet gap between top board and biside plate, and water outlet gap size is carried out calculating according to the process water yield and determined.Distance between the space size of flocculating chamber 2, biside plate and top board, to the distance of reaction tank bottom surface, carry out calculating according to the type of the process water yield, fluoro-containing concentration and flocculation agent and dosage and determine.Water distributing pipe 1 adopts perforation pvc pipe, carries out large resistance water distribution, and its pipe diameter size carries out calculating according to the process water yield and determines, piercing aperture is about 2mm, ensures water distribution uniformity along its length.
The bottom (namely the bottom of reaction tank) in sludge settling district 3 is provided with mud-collecting slot, is provided with shore pipe 7 in mud-collecting slot.The caliber of shore pipe 7 is about 100mm, pipe material selection PVC material, and piercing aperture can select 4-6mm.Sludge settling district 3, except regularly by the mud that shore pipe 7 is discharged, still accumulates a certain amount of mud, further flocculation reaction occurs, to improve flocculating effect with flocculating chamber 2 water.The size in sludge settling district 3 considers can ensure that mud fully flocculates, precipitation is determined.
The swash plate arranged in parallel that sloping plate deposition layer 4 is 80-100mm by spacing forms, and the level inclination of swash plate is 60 °, and swash plate plagioclase is 1.0-1.2m.The bottom of sloping plate deposition layer 4 is provided with gas back-flushing pipe 8, and the top (between sloping plate deposition layer 4 and Filtration Adsorption layer 5) of sloping plate deposition layer 4 is provided with back flushing rising pipe 9, to adopt air water back washing mode to rinse to swash plate.When ensureing to continue water inlet, carry out back flushing by the gas back-flushing pipe 8 be located at bottom swash plate, back flushing water outlet is discharged by back flushing rising pipe 9.
Be equipped with the filtering material particle of certain size grading in Filtration Adsorption layer 5, grain diameter 2-4mm, lay from lower to upper by order from big to small, the filtrate so laid, the main filtration of underclad portion, adsorption is played on upper strata.Filtrate is the activated alumina through modification, has filtration and adsorption function simultaneously.
The top of Filtration Adsorption layer 5 is provided with the water outlet gallery composition of water leg and device both sides.Water leg has 2-3 bar, is evenly arranged along reaction tank length direction.Reaction tank upper outside is provided with the effluent trough 6 be communicated with water leg, and the bottom surface gradient of effluent trough 6 is 1-2%, and the end of effluent trough 6 is connected with rising pipe.
The process of said apparatus purifying treatment height fluorinated water is as described below.
High fluorinated water is before entering reaction tank, and (precipitation agent can select calcium chloride, and flocculation agent can adopt PAM (polyacrylamide), then enters water distributing pipe 1 by inlet channel to add precipitation agent and flocculation agent by pipeline.The fluorinated water adding precipitation agent and flocculation agent is evenly injected in the flocculating chamber 2 for the treatment of unit along water distributor pipe range.Flocculating chamber 2 is made up of side plate and top board, surrounds distributing pipe line along pipe range, has good hydraulics for flocculation process, greatly increases the chance that mud granule collides mutually.In flocculating chamber 2, the abundant hybrid reaction of fluorine in the precipitation agent added and water, form deposit seeds, particle and particle appropriateness are collided simultaneously, under the effect of flocculation agent, the particle of formation can be made again constantly to become large, and the solidliquid mixture so formed leaves flocculating chamber 2, enters sludge settling district 3 from water outlet gap.
In sludge settling district 3, the mud of accumulation keeps certain degree of depth and concentration, forms high-density settling region, and sedimentation effect is good, and fluorine-containing particle completes overwhelming majority precipitation at this.Except maintaining sludge quantity, unnecessary precipitating sludge is by outside perforated sludge discharge pipe 7 regularly discharger, and the liquid after settling region mud-water separation upwards enters sloping plate deposition layer 4, thus completes mud-water separation.
According to shallow pond sedimentation theory, in the process that liquid is advanced at sloping plate deposition layer 4, portion of residual particulate matter wherein will along swash plate landing to mud district, and the clear water part containing a small amount of deposit seeds and fluorion then enters Filtration Adsorption layer 5.So, liquid furthermore achieved that solid-liquid separation at sloping plate deposition layer 4.
Sloping plate deposition layer 4 regularly need carry out back flushing.In the continuous situation of guarantee water inlet, open the gas back-flushing pipe 8 be located at bottom sloping plate deposition layer 4, open the back flushing water shoot 9 between sloping plate deposition layer 4 and Filtration Adsorption layer 5 simultaneously.Under the induced effect of bubble, the solid particulate be deposited on swash plate is taken out of sloping plate deposition layer 4, under the effect of current, outside discharger, completes the back flushing to sloping plate deposition layer 4.
Still containing a small amount of solid particulate and part fluorion in clear water after experience sloping plate deposition.Because the activated alumina of Filtration Adsorption layer 5 by good size grading forms, comparatively large at lower floor's particle, filtration procedure plays a major role, and efficiently can retain deposit seeds remaining in liquid; Upper strata grain diameter is less, and meanwhile, water is after filtering layer, and throw out is effectively removed, and this layer of adsorption is greater than filteration, and fluorion remaining in liquid can be adsorbed preferably and remove.
After filtrate uses certain hour, the method that alkali lye is resolved, molysite activates is adopted to regenerate.The effect of media regeneration is not only that the filtrate making absorption saturated carries out desorb, also cleans filtrate simultaneously, thus avoids the backwash process in operational process.
Process water after Filtration Adsorption layer 5, is collected into the effluent trough 6 of device both sides, is then discharged by rising pipe by the water leg being located at the water surface.So far, high fluorinated water purifying treatment is complete.High fluorine-containing former water is after the process of each links such as flocculating chamber in integrated apparatus 2, sludge settling district 3, sloping plate deposition floor 4, adsorption filtration floor 5, and Funing tablet can be reduced to below 1.5mg/l.
