Cl-、HCO3 -、SO4 2-、NO3-Deng；Common trace element (μ g/L), such as Fe2+、Sr2+Deng；pH；TDS；Hardness etc..
(2) high rigidity underground water flow velocity in water inflow nozzle 21 gradually increases, and forms the water column of high-speed motion, the water column
Inject in suction chamber 22 at a high speed；
Because flow is constant, the cross-sectional area that high rigidity underground water is flowed through in water inflow nozzle 21 is tapered into, according to Q=S
× v, high rigidity underground water flow velocity in water inflow nozzle 21 gradually increases, meanwhile, according to the Bernoulli equation of preferable flow filament, water
Potential energy is converted into high speed kinetic energy, and water column is projected at a high speed from water inflow nozzle 21.
(3) air inlet 221 of suction chamber 22 is opened, air enters suction chamber 22, and the water column surface pressing of high-speed motion is low,
Air into suction chamber 22 is moved under suction function to water column, and air forms attached face under rubbing action on the surface of water column
Layer, and inject mixing chamber 23 with water column；
The bubble and current that air is produced under suction function are uneven, cause big bubble to be broken down into more smaller
Bubble, is presented the increased surface area of index multiple and creates condition for the mixing of air and water, meanwhile, according to Bernoulli's theorem,
If cross section is by S1To S2, correspondence hydrostatic pressureS1＞ ＞ S2When hydrostatic pressure p be substantially reduced,
The potential energy of water is converted into high speed kinetic energy, and water column surface pressing reduction, water column surface pressing is low, and the air into suction chamber 22 is negative
Moved under pressure effect to water column, air forms boundary-layer under rubbing action on the surface of water column, and injects mixing chamber with water column
23。
(4) effluxvelocity of the water column in mixing chamber 23 is first gradually reduced keeps constant afterwards, after pressure also first increases therewith
Keep constant, the air of water column and its boundary-layer is first vigorously mixed and emulsified, form foam stream, afterwards, foam stream is gradually homogenized,
And inject water outlet nozzle 24；
In the leading portion 231 of mixing chamber 23, because cross-sectional area gradually increases, the effluxvelocity of water column is gradually reduced, pressure
Power is gradually risen, and water column is acutely mixed and emulsified with the air with its boundary-layer, and energy transmission takes place and is transmitted with momentum, water
The kinetic energy of post is transmitted to bubble with momentum, and formation can be with the foam stream of high-speed motion.As the foam stream of high-speed motion is in mixing chamber
23 it is inner constantly move forward, energy transfer process proceeds, and finally reaches the energy of water and bubble in the back segment 232 of mixing chamber 23
Amount is homogenized with momentum.
(5) foam stream flow velocity in water outlet nozzle 24 gradually increases, and pressure is gradually reduced, and projects at a high speed；
Due to reducing between the cross-sectional area of water outlet nozzle 24, the flow velocity of foam stream gradually increases, due to the CO of air2Point
Pressure generally 10-3.5(*105Pa), CO in underground water2Partial pressure is general 10-2(*105Pa) left and right, therefore, by jet mixing
Foam stream CO2Partial pressure is obviously reduced.
(6) the foam stream projected is mixed with air, and pressure declines, and returns to cistern, after secondary mixing, processing water
CO2Partial pressure is further reduced, and according to Henry's law, returns to CO in the water of cistern2Concentration is reduced, according to gas-liquid in mixed process
There is reversible reaction in two-phase： Understand, pH increases, HCO3 -Content is reduced, OH-Concentration increase, generation Ca (OH)2、Mg(OH)2、Fe
(OH)3Precipitation forms suspension, makes Ca2+、Mg2+、Fe3+Ion is fixed in the form of colloid or suspension, and then is softened high
Hardness underground water.
High rigidity underground water, periodic monitoring sampling, the change of cistern reclaimed water after acquisition processing are persistently handled using this method
Parameter is learned, the chemical parameters of water before and after the processing are contrasted, you can analysis bating effect.
The present invention makes full use of CO2Partial pressure handles the control action of ground water hardness high rigidity underground water, passes through thing
Reason method, realizes the softening of essence, does not introduce secondary pollution, have the advantages that it is safe and stable, and technique is simple, energy consumption is low,
Effect is good, economic and practical, suitable for being extended to practical application, moreover, the present invention provides technical guarantee for the safe drinking water of resident, it is right
The solution for solving China's drinking-water health problem is significant.
