Description
Technical field
The present invention relates to environmental technology field, be specifically related to a kind of high sulfate radical and high fluorion groundwater treatment
Device.
Background technology
Sulfate radical is widely present in subsoil water, and Crack cause has natural factor, also has man's activity, natural
Sulfate radical essentially from Gypsum Fibrosum, the air slaking of sulfate deposit and leaching in Rocks, Soils, it is also possible to from
The oxidation of metal sulfide.When sulfate radical content is too high, anaerobism sulfate growth of microorganism can be promoted, make sulfur
Acid group is reduced to H2S, water body abnormal smells from the patient fouls, affects water body and normally use；Soil salt can be caused during agricultural irrigation
Stain, suppresses plant growth.Additionally, the too high corrosion that also can cause pipeline or equipment of water body containing sulfate radicals amount.
The water of long-term drink high concentration sulphate will cause the symptoms such as diarrhoea, dyspepsia.Under natural endowment, contain
Fluorine mineral are through hydrogeochemistry and geology long term meetings such as long-term air slaking, dissolving, lixiviation, concentrations
The fluorine causing subsoil water is enriched with.Man's activity is primarily referred to as the pollutant such as industry fluoride waste, waste gas and waste residue
A large amount of discharges, under infilter in body of groundwater.Excess ingestion fluoride can cause dental fluorosis and gastrointestinal tract, kidney,
The pathological changes of nervous system etc., even results in the generation of cancer.
Substantial amounts of scientific research has been carried out containing high concentration sulphate and fluorion subsoil water both at home and abroad to how to process
Work.Each processing method has its merits and demerits.Chemical precipitation method processing method is simple, process side
Just, low cost, but process water can not up to standard or produce secondary pollution.Coagulation sedimentation is economical and practical, equipment
Simply, processing ease, but interference factor is many, can produce secondary pollution.Electrocoagulation is simple to operate, stable
Reliably, but interference factor is many, cost is high.Electroosmose process fluorine removing rate is high and stable, but there is investment
Greatly, operation is strict, can remove mineral useful in water body simultaneously.Additionally, electrode dissolution can substitute into new
Ion component, forms secondary pollution.Ion exchange resin method removal efficiency is higher, but exist expensive,
The problems such as regeneration difficulty, resin rupture, membrane separating method equipment is simple, aquifer yield big, but there is former water and need
Carrying out the problem such as pretreatment, Membrane cleaning, investment operating cost is higher.Absorption method is simple to operate, adsorption effect
Stable, but there is the adsorbent reactivation problem such as frequently.

Biochemical reaction, subsoil water is filtered by ascending zone filler (2-9) simultaneously, lower current area (2-1) and upstream
The mud that district (2-2) produces sinks to mud district (2-3), by the mud discharging valve (2-12) bottom mud district
Emitting, the water after baffling Aeration tank processes passes through baffling Aeration tank overfalling weir (2-11) and baffling aeration
Pond outlet pipe enters up flow type sand filter；
6. subsoil water passes through up flow type sand filter water inlet pipe (3-1) and up flow type sand filter water distributor (3-2)
Entering the bottom of up flow type sand filter, up flow type sand filter water distributor (3-2) realizes water distribution uniformity, subsoil water
Entering sand filtration district, the pollutant in subsoil water are further filtered, and then subsoil water passes sand filtration district, by sand
Filter district's overfalling weir (3-7) and up flow type sand filter outlet pipe flow out, and enter clear water reserviors；Up flow type sand filter drum
The air-flow that blower fan (3-4) produces drives the Sha Heshui in washed-out sand district to flow up, and is rinsed sand simultaneously,
Then sand and water enter sand water precipitation Disengagement zone, and owing to sand is different with the proportion of water, fine deposition goes down and leads to
Cross back sand passage (3-6) and flow into sand filtration district, it is achieved the movement the most from top to bottom of the fine sand in sand filtration district, sand
Water in water precipitation Disengagement zone enters baffling Aeration tank by washed-out sand district overfalling weir (3-5) and washed-out sand water discharge spout
Reprocess；
7. absorption and coagulation sedimentation tank (1) produces precipitate and the mud that baffling Aeration tank (2) is discharged are through dense
Transport outward after contracting, dehydration.
