Description

The proposed technical solution relates to water purification techniques and can be used to purify and provide high-quality drinking water to small settlements and industrial facilities located away from transport highways, as well as residential facilities of social institutions, public catering establishments.

A known installation for water treatment, comprising a housing, the end walls of which are equipped with inlet and outlet pipes of water and sediment. A thin-layer sedimentation tank, a conical sediment collector combined with a camera of a weighted layer of flocculation and a filter with a floating charge are placed in the housing (RF patent No. 2032630, publ. 1995).

A disadvantage of the known installation is the insufficient efficiency of water purification, for the reason that the flocculation process takes place in one zone of a thin-layer sump, there is a large removal of a finer and lighter suspension to the filter.

The closest in technical essence and the achieved result is a water purification unit comprising an electrochemical cell having coaxially located external and internal electrodes with holders mounted at opposite ends of these electrodes, devices for supplying and discharging water, and also a sorption cell installed after the electrochemical cell ( RF patent 2133224, published on July 20, 1999)

The reasons that impede the achievement of the specified technical result of the known unit include the fact that it does not provide for the effective removal of contaminants, such as suspended solids, hydrogen sulfide, ammonia, oil products, iron, heavy metals, manganese, silicic acids.

The task to which the claimed technical solution is directed, and the technical result achieved is to increase the efficiency of water treatment, i.e. effective removal of the above contaminants: suspended particles, hydrogen sulfide, acid, organic compounds, manganese, colloidal iron, ammonia and microorganisms, increasing the life of the system.

The solution of the problem and the technical result are achieved by the fact that the water treatment system including the electrochemical oxidation unit, the filter with carbon sorbent, according to the utility model, additionally contains an automated control unit, and installed in series: mechanical filter, deferrization filter, sorption filter, reverse osmosis installation, tank clean water, pump, ultraviolet sterilizer. For the operation of the electrochemical oxidation unit, a 48 volt power supply is used. The electrochemical oxidation unit is complemented by a magnetic water transducer and an acid regeneration unit, which is a separate portable unit with flexible hoses. The length of the water supply pipeline between the electrochemical oxidation unit and the filters is 6 meters. The deferrization and sorption filters are equipped with autonomous control units. The carbon sorbent filter includes molded plastic covers connected to each other and rolled into the cartridge housing.

Between the distinguishing features and the achieved technical result, there is the following causal relationship.

Supplementing the system with a mechanical filter, a deferrization filter, a sorption filter, a reverse osmosis unit, and an ultraviolet sterilizer, as well as upgrading the electrochemical oxidation unit, increases the life of the system and allows you to effectively purify water from silicic acid, organic compounds, manganese, colloidal iron, hydrogen sulfide, ammonia, and microorganisms.

The drawing shows a diagram of the proposed water treatment system.

The system includes sequentially installed: a mechanical filter for water purification 1, an electrochemical oxidation unit 2, a deferrization filter 3, a sorption filter 4, a reverse osmosis unit 5, a clean water tank 6, a pump 7, a main filter 8, which is a filter with a carbon sorbent, an ultraviolet sterilizer 9, automated control unit 10. The electrochemical oxidation unit 2 is equipped with taps 11,12 for connecting a portable acid regeneration unit (not shown). The pipe 13 between the electrochemical oxidation unit 2 and the filters 3 and 4 has a length of 6 meters. Filters 3 and 4 are equipped with autonomous control units 14 and 15, respectively. The areas of the outer and inner electrodes of the electrochemical oxidation unit 2 are increased 2.5 times in comparison with the known ones and comprise: the outer area - 1648.5 cm ² and the inner - 942 cm ² . For the operation of the electrochemical oxidation unit 2, a power source of increased power (not shown) with a voltage of 48 volts is used, instead of 24 volts of the prototype. The composition of the electrochemical oxidation unit includes a magnetic water transducer (not shown), which allows to reduce the formation of scale on the electrodes of the unit. To flush the electrochemical oxidation unit 2, an acid regeneration unit (not shown) is connected to it through taps 11, 12, which is a portable unit with flexible hoses.

The system operates as follows.

Water supply is carried out, as a rule, from sources of artesian or surface water located near shift camps, settlements, enterprises, houses, recreation centers, etc.

Source water, before entering the system, undergoes a laboratory analysis according to the following indicators:

1. Total mineralization, mg / l

2. Turbidity, EMF

3. pH

4. The content of free chlorine, ozone, mg / l

5. Petroleum products, mg / l

6. Total hardness, mEq. / L

7. Iron content, mg / l

8. The manganese content, mg / l

9. The silicon content, mg / l

10. Color, in degrees

11. Permanganate oxidation, mg / DM ³

12. The total hardness, mol / DM ³

13. Ammonia, mg / dm ³ l

Depending on the values of indicators, the qualitative and quantitative composition of the technological equipment of the system is adjusted.

Water enters the mechanical filter 1, where it is cleaned of mechanical impurities, then enters the electrochemical oxidation unit 2. Changing the design of the electrochemical oxidation unit 2 allows for the efficient oxidation of ferric iron, even with low salinity of the water. By increasing the length of the pipe 13 increases the time of the oxidative reaction, which entails a decrease in organic compounds. The use of a deferrization filter 3 in the system with a Sorbent MS Super Ferox charge allows efficient removal of manganese, with the use of Ecoferox to purify water from ferrous iron, and with a Zeolite charge of ammonia. Sorption filter 4, loaded with activated carbon, improves the organoleptic characteristics of water. Supplementing the installation with a reverse osmosis unit 5 allows you to effectively purify water from a high content of hardness salts, organic compounds of silicon, colloidal iron, and microorganisms. Water after filter cleaning enters the clean water tank 6, from where, after additional cleaning with the main filter 8, through the ultraviolet sterilizer 9 is pumped to the consumer by pump 7.

The table shows the indicators of water quality before and after cleaning the proposed system.

No. p / p The determined indicator unit of measurement ND at MVI MPC ^1.2 results Before cleaning After cleaning one Iron is common mg / dm ³ GOST 4011-72, clause 2 0.3 ² 3.73 0.335 2 Permanganate oxidation mgO ₂ / dm ³ PNDF 14.1: 2: 4.154-99 5 ² 2.92 0.383 3 Turbidity mg / dm ³ GOST 3351-74, clause 5 1.5 ² 3.60 <0.5 four Manganese mg / dm ³ GOST 4974-72, clause 3 0,1 ² 0.46 0.17 5 Hydrogen Index (pH) units pH PNDF 4.1: 2: 3: 4.121-97 6-9 ² 7.2 6.3 6 Color color degree GOST R 52769-2007, clause 5 20 ² 42.5 6.9

As can be seen from the table, the obtained indicators confirm the quality of the purified claimed water treatment system.

The system is equipped with an automated control unit 10, which controls the operation of the entire system, while the system can autonomously operate in several modes: filtration mode, hydraulic flushing mode and standby mode.

In filtration mode, the unit continuously purifies water.

In the hydraulic flushing mode, the pump 7 continues to work and supply water to the consumer from the tank 6, while the filters of the blocks 1, 3, 4, 5 automatically switch to the hydraulic flushing mode.

The proposed system has a high resource and the ability to effectively purify water from a large number of contaminants.
