The invention is illustrated by drawings. In Fig.1 shows a block diagram of the system of water treatment and supply of feed mixture is water and feeding the mixture into the soil under drip irrigation.

Information confirming the possibility of carrying out the invention are as follows.

Water treatment system and feeding the mixture into the soil under drip irrigation (see Fig.1 and 2) includes hydraulically connected water source 1, a pumping station 2, a container 3 for the preparation of the nutrient solution, the filter 4, the pressure gauges 5, 6, 7, 8 and 9, the fixture in the form of valves 10, 11, 12, 13, 14, 15, 16 and 17, the pipeline 18, the network of distribution and irrigation pipes 19, 20, and individual and/or group dropper 21.

Water treatment and supply of feed of the mixture relative to the irrigation pipes 20 and the IV 21 geographically removed to a distance of not more than two or three kilometers. When reducing the length of the pipeline 18, the efficiency of the system increases dramatically.

Filter 4 for purification of water from source 1 (open water or well) made a three. The first cleaning stage is designed to remove mineral dust, vegetable matter and sediment with a minimum size of particles up to 0.5 mm and is made in the form of a hydrocyclone 22. The hydrocyclone 22 are provided with concentrically mounted in the cavity self-cleaning strainer 23 and sedimentary camera 24 Deena as filled with filtration material 25 is horizontally installed capacity 26. The container 26 is made of different size concentric set of thick-walled pipes 27 and 28. The ends of the tubes 27 and 28 are mated plugs 29 and 30 of sheet steel with a thickness of 16-20 mm

Filtration fabric 25 is presented in the form of calibrated sizes of sand with a diameter of grains 1-6 mm As an option to increase filter performance filter material 25 is presented in the form of layers placed in the vessel 26 the second stage of filtration coarse washed sand and gravel with a particle size of 0.5 to 2.0 mm, respectively. As a major substitute used crushed dolomite with grain size 5-20 mm bulk density is 1.3 t on m3. Volumetric mass of rubble 2,62 t/m3. Mark frost is F=200, strength 1000-1200 kg/cm2(100-120 MPa). As fine aggregate used quartz sand with fineness modulus of 2.5. The content of silt and clay impurities does not exceed 1%. The grain size of 1-5 mm In the tank 26 is properly placed upper slit pipe 31 and the lower drain pipe 32. Drainage pipes 32 are interconnected by a manifold 33 (see Fig.2). The manifold 33 with the upper slotted pipe 31 is connected by a strut 34 and the valve 16 (see Fig.1 and 2). Pipes 31 and 32 provide a supply of water from hydrocyclone has a network for drainage of product contamination. The upper slit pipe 31 with the lower drain pipe 32 is connected through the valve 16 to the riser 34. The third stage of water purification are presented in the form of a horizontally installed in the housing 45 slotted filter 36. Slotted filter 36 in the housing 35 of the third stage of water purification is installed with possibility of rapid disassembly.

Capacity 3 to prepare the nutrient solution hydraulically connected in parallel in the network between the first and second stages of the filter, i.e. in the pipe 37, a split valve 14. At the input and the output of gate 14 are mounted by means of nipples gauges 6 and 7 and the valves 12 and 13. The output ends of the valves 12 and 13 of the pipes 38 and 39 are connected with the hermetic container 3. Cavity capacity 3 periodically fill soluble mineral fertilizers, macro - and micronutrients, herbicides or other solutions for improving the nutritional mode of cultivated plants.

Filter 4 the second stage of filtration provided with a possibility to remove colmatage from the cavity horizontally installed an air-tight container 26. For this purpose, the riser 34 is equipped with a valve 15 and divided into parts by the second valve 16, which separates the upper slit pipe 31 and the drain pipe 32 when cleaning water in the tank 26.

ICI is eskay network is mounted on the nozzle housing 35 per slot filter 34 of the third stage of filtration of irrigation water before feeding into the pipeline 18. Mentioned the pipeline 18 is hydraulically connected to a distribution pipe 19 through a pressure regulator 41, provided with a pressure gauge 9. In the network between the counter 40 water flow and filter third stage (case 35) mounted pressure gauge 8.

In the network between the 2nd pump station and the hydrocyclone 22 installed valves 10 and 11 and the pressure gauge 5. Similarly in the hydraulic network between the hydrocyclone 22 of the first stage of cleaning and fine cleaning filter 4 of the second stage is mounted the valve 14, the inlet and outlet of which is placed a pair of pressure gauges 6 and 7 to control the water pressure in the vessel 3 to prepare the nutrient solution. Sequentially installed in the hydraulic network group pressure gauges 5, 6, 7, 8 and 9 if the pump 2 control the entire cycle of supply and purification of water.

Water treatment system and feeding the mixture into the soil under drip irrigation works in the following way.

The system will cover the three most typical cases of exploitation in the period of vegetation cultivated irrigated crops: 1) drip irrigation; 2) feeding macro - and microelements; 3) cleaning a filtration material and remove colmatage.

Volost hydrocyclone 22. Gauge 5 records operating inlet pressure in the hydraulic network of the filter 4. Under the action of gravitational and centrifugal forces in the cavity of the hydrocyclone 22 heavy and large mist, mineral Sora and vegetable impurities from the surface of the strainer 23 is deposited in the chamber 24 to collect food contamination. Water flowing through the cracks of the filter 23 is supplied to the pipe 37 and the open valve 14 is directed to a container 26 of the filter 4 through the upper perforated or slotted pipe 31. Submitted by the pipe 31, the water is evenly distributed over the surface of the filtration material 25 is placed in the vessel 26. Under the action of gravitational forces and excess pressure, the water molecules penetrate the pores between adjacent grains of sand and/or gravel, and move in the direction of the drain pipe 32. Suspensions with particle sizes of 0.1-0.5 mm are deposited in layers of sand and gravel. Purified water through the drain pipe 32 from a sealed container flows into the reservoir 33, and enters the body 35 of the third stage of purification. Slot filter 36 are received suspensions with particle sizes less than 0.1 mm after Passing through the cavity of the counter 40 flow rate (volume) of irrigation water, the latter under pressure through pipelines 18 direction of the water in the drip 21 through distribution and liquid piping 19, 20.

Each dropper 21 in a strictly dosed volume issues within 2-4 hours individually required irrigation water under the root of each plant.

When fertilizing irrigated agricultural plant macro - and micronutrients in the vessel 3 fall asleep soluble mineral fertilizers (urea, urea, Amorosa or other). Cover tightly close the container 3. Valve 14 reduces the living section of the pipe 37. Gradually open the valve 12 of the pipe 38. This vessel 3 create a mother solution of mineral fertilizers. Next, open the valve 13. Thus part of the pre-purified water filter 23 hydrocyclone 22 is directed into the container 3, and dissolved mineral fertilizer pipe 39 are carried in the upper pipe 31 of the filter 4. Sludge and other insoluble components from the composition of the fertilizer is deposited in the filter 4 in the layers of sand and gravel filter material 25.

Next, purified water with dissolved nutrients above technique is directed into the drip 21. Macro - and microelements together with water are carried in the root layer of soil and the shortest path sucking absorbed by the plants roots.

Similarly entered HUS and the emblem of tracing material 25. First block the flow of water into the housing 35 slotted filter 36. Then open the valve 16 to the riser 34. Keeping in mind that the water in hydraulic networks is moved along the path of least hydraulic resistance to the flow of water from the pipe 31 on shaft 34 through the valve 16 is directed into the reservoir 33, and into the drain pipe 32. In the cavity of the container 26 is created upward countercurrent. Starts washing the filtration material 25. Raised from the surface of the filtration material 25 sediment and suspended solids are routed through the cracks in the cavity 31. Colmatage from the tank 26 is displayed outside of the filter 4 at an open valve 15. Change the operating mode “cleaning the filter” - “remove colmatage” submission of pre-treated water contributes to the stable operation of all droppers during the entire irrigation period. Suspension from the chamber 24 is removed by opening the valve 17.
