Embodiment
As depicted in figs. 1 and 2, a kind of arsenic removal water purifying plant includes waterpipe 1, described water inlet pipe 1 is provided with line mixer 3, described line mixer 3 is provided with oxidizer filler 16 and flocculation agent filler 2 successively according to water (flow) direction, and potassium permanganate oxidant and Ferric Salt Flocculants inject described line mixer respectively by described oxidizer filler 16 and flocculation agent filler 2.Former water after described water inlet pipe 1 successively through flocculation basin 4, distribution reservoir 5, settling tank 6 and filtering basin 11.Described flocculation basin is provided with 9 flocculation wells, is provided with coagulant aids filler 17 in the water inlet according to the flocculation well of the 3rd in water (flow) direction.The middle part of described settling tank 6 is provided with inclined tube 8, and the top of described inclined tube 8 is provided with water leg 7.The bottom of described settling tank 6 is provided with several coherent V-shaped groove.The blow-off pipe 15 being positioned at described settling tank 6 is corresponding to the position bottom described V-shaped groove.Described filtering basin 11 top is provided with bypass channel 9, and described bypass channel 9 is with described water leg 7 by being positioned at the opening in communication above pool wall, and the bottom of described bypass channel 9 is provided with quartz sand filter media 12, is provided with normal sands filtrate 13 on the downside of described quartz sand filter media 12.Described filtering basin 11 are equipped with liquidometer 10 and blow-off pipe 16, and described blow-off pipe 16 is provided with wash water valve.Described flocculation basin and distribution reservoir are also provided with blow-off pipe 16, and described blow-off pipe 16 is provided with wash water valve.
Implementation process is as follows:
1, former water enters line mixer 3 through water inlet pipe 1, adds potassium permanganate oxidant, add Ferric Salt Flocculants at flocculation agent filler 2 at the oxidizer filler 16 of line mixer 3, after line mixer 3 fully mixing, enters flocculation basin 4.
2, potassium permanganate oxidant carries out pre-oxidation treatment to former water, rapidly the trivalent arsenic in water can be oxidized to pentavalent arsenic, the pentavalent arsenic in a large amount of ironic hydroxide alumen ustum planar water formed by Ferric Salt Flocculants.Flocculation basin 4 is provided with 9 flocculation wells, and eddy flow is effective, and mixed former water fully mixes in flocculation basin 4, react formation alumen ustum.Add coagulant aids at the coagulant aids filler 17 of flocculation basin 4, accelerate the formation of flco.Along with the carrying out of reaction, alumen ustum can be increasing, can well pentavalent arsenic in planar water.Large alumen ustum can be formed at flocculation basin 4 and enter distribution reservoir 5 below.
3, in distribution reservoir 5, abundant reacted water carries out uniform water distribution on the water inlet direction of settling tank 6.
4, after distribution reservoir 5 carries out uniform water distribution, water enters settling tank 6 by the bottom of settling tank 6, from bottom to top through inclined tube 8.The flowing of water in inclined tube 8 is more stable, and the alumen ustum of some macrobeads absorption pentavalent arsenic toward declining, is gathered in the bottom of settling tank 6, be discharged by blow-off pipe 16.Bottom due to settling tank 6 is provided with several coherent V-shaped groove, plays good congregational rate to the alumina blossom particles be deposited at the bottom of pond.The position being positioned at the blow-off pipe 16 of the sidewall bottom of settling tank 6 is corresponding to the position bottom described V-shaped groove, and filth-discharging effect is good.Clear water can be gathered in the top of settling tank 6, is catchmented by water leg 7, enters filtering basin 11.Water flow stationary near water leg 7, is conducive to alumina blossom particles and precipitates further.
5, after water enters filtering basin 11, through the evenly point water of bypass channel 9, some little cannot being removed after quartz sand filter media 12 filters by precipitation removal flco, the water after having filtered completes filtration through normal sands filtrate 13 again.The water filtered can meet daily water consumption standard.
After filtering basin 11 run for some time, quartz sand filter media 12 inside filtering basin 11 and normal sands filtrate 13 have retained the dirt in water, along with the dirt retained gets more and more, the filtration capacity of quartz sand filter media 12 and normal sands filtrate 13 declines, the liquid level in filter tank is caused to rise, when filter tank liquid level rises to certain altitude, liquidometer can trigger automatic control program, starts and carries out back flushing to quartz sand filter media 12.Back flushing is from clean water basin water intaking, has been come by backwashing pump.Oppositely intake by the rising pipe 14 in filter tank 11, rinse quartz sand filter media 12 and normal sands filtrate 13 bottom filter tank 11, sewage is discharged by blow-off pipe 16.
Owing to have employed technique scheme, by adding Permanganate, pre-oxidation treatment is carried out to former water, rapidly the trivalent arsenic in water can be oxidized to pentavalent arsenic, a large amount of ironic hydroxide alumen ustum that can be formed after adding Ferric Salt Flocculants, pentavalent arsenic in ironic hydroxide alumen ustum planar water, what formed contains the separated removal in follow-up settling tank and filter tank again of arsenic alumen ustum, reaches good effect of removing arsenic.In addition, Permanganate use cost low and be easy to control consumption, handled easily, can not produce harm to operator.Reaction tank is divided into nine flocculation wells, and eddy flow is effective, and reaction thoroughly.The use of liquidometer ensure that the accurate operation of water purifying plant, ensures water quality.V-shaped groove bottom settling tank plays congregation to the dirt being deposited on bottom, and blowdown is thorough.Settling tank top is provided with water leg, stationary flow, and particle-removing thing is effective.The utility model arsenic removal purifying water effect is good, easily implements.Instrument and supplies flow process is simple, easy handling, management and maintenance.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
