Description
Technical field
This utility model belongs to environmental conservation and Water purification technical field, and in particular to it is saturating that one kind combines cation selective
The electrochemistry of film is crossed except hardness and sterilization water treatment facilities.
Technical background
Life of the hardness to people in water supply is caused with production and had a strong impact on.It is hard in tap water used in daily life
Spend height and cause serious with foulings such as hydroelectric generators, and it is healthy to have had a strong impact on people.In commercial production, feed-water hardness is too high
Easily dirt is formed in recirculating cooling water system and water equipment inner surface, cause the decline of heat-exchange apparatus efficiency, equipment clear
Wash maintenance frequent, cause higher equipment maintenance cost.
It is usually used in water with feedwater except the technology that hardness softens includes medicament method (lime-soda method), ion exchange
And membrane separation process etc., the device based on these methods using more complicated, and used relatively large pharmacy response, regenerative agent or
Antisludging agent etc., operating cost is high, and not environment friendly technology.Also often using antisludging agent and sterilization in industrial circulating cooling water operation
Agent etc. prevents fouling and bacteria growing inhibiting, can bring up to higher recirculated water cycles of concentration, but medicament is made using one side
It is high into operating cost, on the other hand cause with pollutant such as phosphorus in sewer, it is more serious to water pollution.
Using electrochemical appliance except hardness is paid close attention in recent years, its cardinal principle is：Under the function of current, negative electrode is obtained
There is reduction reaction (such as following formula 1-2) in electronics
O2+2H2O+4e-→4OH-Formula 1)
2H2O+2e-→H2+2OH-Formula 2)
Reaction above has been formed about alkaline environment in negative electrode, can cause calcium ion, magnesium ion and part heavy metal
Ion reacts (such as following formula 3-4) and crystallizes or Precipitation, and so as to reach the purpose that hardness produces softened water is removed.
Ca2++HCO3 -+OH-→CaCO3+H2O formulas 3)
Mg2++2OH-→Mg(OH)2Formula 4)
Meanwhile, under the function of current, anode loses the oxidation reaction that electronics occurs water or chloride ion, discharge oxidability compared with
Strong free radical or active chlorine and active oxygen etc., the effect with sterilization.
Using electrochemistry except hardness sterilization tool has great advantage, such device does not use chemical agent, while realizing except hard
Degree and bactericidal effect, belong to environmentally friendly device.But at present electrochemistry is except hardness sterilizing unit is in domestic water and industry
Also it is not used widely in feedwater, it main reason is that the electrochemical reactor that Conventional electrochemical is adopted except hardness device
It is interior, corresponding one or more groups of electrodes are only included, to intake from the electrochemical reactor one end and flow into, serial or parallel connection is flowed through respectively
Group electrode, then flows out from electrochemical reactor outlet.In electrochemical reactor between each group electrode, not by anode and cathode chamber
Effectively separate, therefore with following deficiency：1) because alkaline environment exists only in region very narrow near negative electrode, and by mass transfer
Process etc. affects, and except hardness reaction rate is slower, hardness ions removal efficiency is relatively low, needs polar plate area larger；2) hardness from
Son is easily deposited on cathode plate surface and forms dirt, causes resistance to increase, and reaction efficiency declines, and needs frequent disassembly, cleaning, is to set
Standby operation maintenance brings difficulty；3) crystalline deposit that reaction is formed is deposited under gravity reactor bottom, partial reaction
Device bottom arranges settling zone and bucket, periodically discharges the sludge that dirt is formed, but in actual motion, easily due to bucket with
Incrustation of pipe deposition etc. causes spoil disposal difficult, needs frequent demolition and maintenance.Therefore, it is necessary to development of new electrochemistry is killed except hardness
Bacterium device is applied with promoting its.
