Description
Technical field
The present invention relates to the structures of turbidity and temporary hardness in a kind of collaboration removal surface water.
Technical background
China has a vast territory, and landforms are varied, and the water quality for flowing through surface water at different landforms is different.Karst
Looks refer to the flowing water erosion, again to solublerock (carbonate rock, sulfuric acid rock salt, halogen rock etc.) based on chemical corrosion
Geologic process supplemented by the effects that power collapses is formed by special geomorphology.The distribution of Karst In China landforms is wide, area is big, Zhan Zong states
About the 13% of native area, wherein maximum with Guangxi, Guizhou and Eastern Yunnan occupied area, the soil that Guizhou Province is more than 70% is noise made in coughing or vomiting
This specially looks.
With China equally there is a large amount of undissolved suspended materials, colloid in other regional surface water with karst surface water
Substance and microorganism.Meanwhile the hardness for flowing through karst surface water is higher, hardness formation mechenism is the carbon of indissoluble
Carbonate Rocks generate soluble bicarbonate ion and free metal ion (mainly calcium under water and carbon dioxide effect
Ion and magnesium ion) it is moved in water by rock, flow itself, which has, washes away corrosion, they often add blocking rock
Work accelerates the corrosion of rock at particle, to increase the hardness of water.In karst due to carbonate rock and river
Area largely exists so that the corrosion phenomenon of rock occurs extensively, this is also the high main original of karst river hardness content
Cause.Incrustation scale is formed by temporary hardness during boiling water, i.e. carbonate hardness, is a part for total hardness, is equivalent to
Calcium, the magnesium combined with heavy carbonate in water and a small amount of carbonate is formed by hardness, when boiling is boiled, calcium, magnesium heavy carbonate
It decomposes and generates precipitation to reduce the hardness of water, part hardness can be removed with the method boiled.If calcium and magnesium in hard water
Mainly exist in the form of sulfate, nitrate and chloride etc., as permanent hardness.
Incrustation scale leads to the aesthetic difference of drinking water more, and to resident living and health, there are potential impacts.Although China
《Standards for drinking water quality》The total hardness of middle regulation water must not exceed 450mg/L, but there is no limit regulations to temporary hardness.
A large amount of existing HCO in the surface water of karst3 -And CO3 2-There is a large amount of precipitations and floating material in water after boiled in ion,
Turbidity is caused to increase, part water turbidity is more than 5NTU, this about turbidity and there must not be visible regulation contradiction with Drinking Water in China.
China《Standards for drinking water quality》It is formulated with reference to WHO and western developed country relevant criterion, formulates foundation
It is to drink unboiled water, and often differ greatly to boil water to drink with China resident, the former mainly drinks the calcium and magnesium ion of dissolving, I
What state resident drank is that part ion is converted into calcium carbonate, and long-term drinking high carbon acid calcium water influences normal person unknown.Do not pass through
Once often people's long-term drinking hard water of reference hard water, then will appear malaise symptoms, cause diarrhea and functions of intestines and stomach disorderly, i.e., it is so-called
" not acclimatized "；It is done washing with hard water, soap foams less, causes to waste；The flesh of fish, vegetables are cooked with hard water, it can be because being not easy to be cooked
And reduce the nutritive value of food；It is washed hair with hard water, hair can be made to cohere, embrittlement etc..
The technology of processing high hardness water mainly has medicament tenderizer, ion-exchange and film tenderizer at present.Medicament softens
Method is suitable for the small situation of water consumption, and high expensive is run when water consumption is big, makes answering for water due to adding chemical substance
With being greatly limited.Ion exchange softening method complex process equipment needs to consume a large amount of acid or salt is cooked regenerative agent, cost
It is relatively high.Power consumption is larger in film tenderizer operational process, and water producing cost is higher.Ion-exchange and film tenderizer all need
Relatively complicated preprocessing process is wanted, to mitigate the pollution that resin or membrane material are subject in main process, ion exchange makes water
The increases such as middle sodium ion.
Existing softening technology processing cost is high, is badly in need of a kind of economic removal karst surface water incrustation scale technique.I
The common earth surface water source total hardness of state meets《Standards for drinking water quality》, but the dissatisfied complaint of the masses caused by incrustation scale is more
See, existing treatment technology, complicated and huge processing system need to be built in water factory, and processing cost is high.And from existing research
Achievement shows that dissolving calcium magnesium ion does not make significant difference to human body, seeks the skill for economically handling karst surface water incrustation scale
Art, for improving this area's drinking water sense organ and elimination, to drink calcium carbonate potential problems extremely important, up to the present domestic
Outside about water hardness treatment research is drunk, focusing primarily upon total hardness reduces in technique, and not to incrustation scale, that is, temporary hardness research
It is common, no maturation process and equipment.Therefore the present invention, which is put forth effort on, seeks a kind of simple and practicable, and the place that cost is quite cheap
Reason method removes temporary hardness, while can cooperate with turbidity in water removal.
