The present invention relates to chemical technology and engineering water treatment and water solutions.

The invention can be used in all branches of industry, energy, agriculture, medicine, municipal and aquaculture.

The specific implementation of the invention it is planned in the production of obtaining coloradoraising drinking water and beverages for the food industry, environmental technology and engineering.

Analysis of gas, vapor and liquid oxygen-containing mixtures synthesized by the known physico-chemical methods [1-3], shows that compounds are composed of the following sustainable elementary (atomic and molecular) compounds:

(H₂O)n↔ n(N₂O) - liquid-vapor; (H₂O₂)m↔ m(N₂O₂- liquid-vapor; O₂gas; H₂gas; O₃gas.

Energy saturation and physico-chemical properties (solubility in water and in aqueous solutions, boiling point and evaporation and other) oxygen-containing mixtures are determined by the depth of flow is reversible reactions of synthesis and degradation (1-4):

Oxygen-containing mixture (air, air + O₂air + O₃, an explosive mixture of N₂+O₂and others) with physico-chemical St is isthmi, certain reactions (1)-(4), and energy content E₁-E₄widely used in water treatment for saturation of water with oxygen in order conditioning, water purification and disinfection.

Known ejection method of saturation of water with oxygen and installation for its implementation [1, s-264]. In this way water flows into the ejector pressure in the pressure pipe. Due to the organized flow of water through the nozzle into the expansion chamber in the chamber of the vacuum ejector creates a vacuum, which is used to suck oxygen-containing gas mixture and mixing in the expansion chamber of the apparatus with the flow of the treated water.

Installation for the implementation of the ejection method includes discharge pipe treated water, the ejector, the node for connecting and adjusting the flow rate of treated water in the ejector, a pipe connecting the chamber of the vacuum ejector with a source of oxygen-containing gas (gas-vapor mixtures. Technical solution [1, s] used oxygenated mixture of air + O₃So the camera vacuum ejector in the installation of pipe connected to the valve for suction air flowing through (gas) tubular ozonizer connected to the source of high voltage.

The entrainment and mixing of keys is oradatabase mixture (air + O ₃) from the treated water in ejection installation occurs instantly (suction - fractions of a second, mixing seconds), the energy consumption for mixing gas with water is minimal.

Disadvantages ejection method of saturation of water with oxygen:

low oxygen saturation (oxygen-containing gas mixtures - not more than 8-9 mg O₂/ l H₂O under normal conditions);

- instability status of dissolved oxygen with maximum saturation processed under normal conditions water (9 mg O₂/l H₂O).

Disadvantages installation for the implementation of the ejection method:

- the high cost of oxygen-containing gas mixture and energy on the process of saturation of water with oxygen (9 mg O₂/l H₂O under normal conditions)related to the limited solubility of oxygen-containing gas mixture under normal conditions and the design of the facility.

There is a method of saturation of water with oxygen pressure flotation and system with recirculation water flow for its implementation [4, s], allowing to obtain high concentrations of dissolved in the treated water of oxygen and, as a consequence, high purity water.

Building a system known technical solutions [4] is the closest to the claimed solution of the hydraulic system in the installation.

When mixing in the lower part of the vessel supersaturated with oxygen water, under the cumulative pressure tank under minimal pressure from 1.5 to 2.0 MPa, with treated water and oxygen to pass into the treated water and the excess is excreted in the form of bubbles of oxygen-containing gas, which together with mixed with water up to the top of the container.

In the upper part of the flotation tank is selected processed (kislorodozawisimae and purified from particles of impurities) of water. Water purification from impurities produced in the upper part of the vessel by sucking the foam floating on the surface of the water.

Unlike ejection method of saturation of water with oxygen minimum time of transportation oxygen-containing gas mixture, dissolved under pressure in the treated water increased to 2 minutes, the minimum mixing time up to 10 minutes. The consumption of oxygen-containing gas mixture to the processing water is reduced relative to the ejection method in the order is not more than 5% of the volume of treated water).

The system for implementing the method of pressure flotation includes capacity (column)in the lower part is connected to the pressure pipe treated water and the pressure pipe of circulation the flow of water-gas circuit supersaturated with oxygen in the treated water, in the upper part of the treated water pipeline and the pipeline for the overflow of water and remove from the water surface foam with particles flotated impurities.

The circulation-flow water-gas circuit flotation system consists of series-connected pipeline: site selection of piping treated water, devices for suction oxygen-containing gas mixture that is installed on the suction line of the pump, the cumulative pressure tank installed on the discharge line of the pump, connected to the flotation tanks.

Unlike ejection installation [1, s] flotation system allows to obtain supersaturated oxygen water in relation to kislorodozawisimae water at normal storage conditions (9 mg O₂/l H₂O). However, the stability of supersaturated oxygen status of the treated water under normal conditions of storage of water is small and time saving supersaturated oxygen water conditions commensurate with the processing time of water in the system (maximum hours).

The disadvantages of the method of saturation of water with oxygen pressure flotation:

the low saturation of the treated water with oxygen associated with the unstable state of supersaturated oxygen water, under normal conditions in the flotation system;

- high costs is the power on the process of saturation of water with oxygen, associated with the need to maintain a positive pressure in the circulation-flow water-gas circuit flotation system.

Disadvantages of the system for implementing the method of pressure flotation:

- inability to use effective oxygen-containing gas mixtures (for example, explosive mixture of N₂+O₂produced by the electrolysis of aqueous solutions) due to constructive solutions in the building of the circulation-flow water-gas circuit system (for example, the use of cumulative pressure tank in communication with the explosive explosive mixture), high energy intensity.

Partially the above disadvantages of saturation of water with oxygen-containing gas is deprived of the modernized method of water treatment using both pressure and electrical flotation [5, p.32].

Improving the efficiency of the process of saturation of water with oxygen in this way and, as a consequence, increasing the depth of water purification from impurities is achieved by simultaneously mixing the treated water with a previously processed the same way supersaturated oxygen water and explosive mixture of N₂+O₂released from the electrodes in the form of charged gas bubbles in coloredpaneswindow processed and treated water flowing water electrolyzer installed between the circulation-FR is cnym water-gas circuit and flotation capacity (column).

Application in flotation tanks charged bubbles of the gas mixture of H₂+O₂allows to stabilize at atmospheric pressure and ambient temperature unstable supersaturated oxygen water (not less than on the order in relation to the way pressure flotation).

In supersaturated oxygen processed by the method [5] water oxygen concentration under normal conditions is maintained in the range of 9-15 mg O₂/l H₂O charge explosive mixture of gas bubbles H₂+O₂and increasing the partial pressure of oxygen in the explosive mixture in relation to its value in air of not less than 50%.

The main disadvantages of this method [5, S. 32]:

low oxygen saturation of the treated water;

- not high enough (for example, bottled drinking water level stable in time supersaturated oxygen status of the treated water under normal conditions;

- pollution oxygenated water harmful products of electrolysis (active chlorine, heavy metal ions), the use of electrode unit with a large surface electrodes, high consumption of electrode material on the process of saturation of water with oxygen.

The disadvantage of this method [5] part of the electrolytic cell and method for production of ecologically pure explosive mixture Hsub> 2+O₂eliminated in the electrochemical system [6]. Products pollution oxygen-containing gas mixture H₂+O₂this method and system are only water vapor and alkali.

This system can be applied in modernized facilities [5] when the ejection input explosive oxygen-containing mixture of N₂+O₂. Therefore, the construction stated in the installation plasmamembrane system was used in the construction of electrochemical systems [6].

Taking into account the conducted analysis of scientific-technical and patent information technical solution to the problem is to increase the efficiency of water treatment oxygen-containing gas by increasing the depth of saturation of water with oxygen and sustainable in time kislorodozavisimogo state of water under normal conditions, reducing energy consumption for the processing and consumption of the equipment in the process of mixing the gas with water.

The solution is achieved:

1. A sequential ejection pressure flotation mixing obtained plasmamembrane way oxygen-containing gas mixture H₂About₂+ O₂with treated water, allowing to increase the efficiency of water treatment oxygen-containing gas, to modernize the system pressure of the fleet the AI and to reduce the energy consumption for water treatment.

2. The use of anomalous physical-chemical properties of oxygenated steam-N₂About₂+O₂mixtures for deep saturation of the treated water oxygen and sustainable in time supersaturated oxygen status of the treated water under normal conditions.

3. The use of anomalous physical-chemical properties of oxygenated steam-N₂About₂+O₂mixes instantly (within seconds) will dissolve when mixed with the treated water for its ejection input pressure part of the upgraded flotation system between the pump and the column (capacity).

4. The use of anomalous physical-chemical properties of oxygenated steam-N₂About₂+O₂the mixture interact with remasterise materials and hydrocarbon polymers used in the water treatment system of oxygen-containing gas.

The possibility of using oxygen-containing gas mixture H₂About₂+O₂received plasmamembrane method [7], to achieve a technical result in the above task, theory predicts bipolar plasma electrode (abdominoperineal resection), the schematic construction of which is represented by figure 1.

Conducted by the applicants further development of theory abdominoperineal resection [7] shows that p and potentials in plasmamembrane from 140 to 220 volts film himatangi plasma, surrounding the cathode (acting as abdominoperineal resection), the formation of water-oxygen clusters, which should be stable in the gas mixture of H₂About₂+O₂and liquid water.

Their structure determine the physico-chemical reactions occurring in aqueous electrolyte solution of plasmamembrane between abdominoperineal resection and molecular oxygen released from the anode:

Anode:

Abdominoperineal resection: O₂+(G⁺+4H₂O+H₄O₄+4E

where: when driving in an electrochemical circuit plasmamembrane four electrons (n=4) abdominoperineal resection is respectively:

(4H₃O⁺+4H₂O)→ (R⁺+4H₂O) and (4H₂O+ON^-)→ (H₄O₄+4E
