MODE FOR CARRYING OUT THE INVENTION

(3) The equipment for the disposal of cyanobacteria in stagnant waters comprises the supporting float 5, in the form of a closed hollow cylinder, containing the transversely positioned rib 4. Mounted on it is the device 9 for utilizing wind energy, which drives the water pump 2, placed in the delivery pipe 3 and the electric power supply—the alternator 10. The upper supporting part of the equipment—the upper float 7, copies the shape of the supporting float 5, it is made of a dielectric, light, floating material and serves for anchoring the grid electrode 6, as a system of radially distributed electrodes. Placed on the upper float 7, there are the photovoltaic cells 8, interconnected to the bipolar electrodes 1 and 6. The alternator 10. also supplies the bipolar electrodes 1 and 6 with direct current. Hanged on the rib 4, there is the suspended electrode 1, connected to the sources of photovoltaic cells 8 and alternator 10. The body of the supporting float 5 of the equipment for the disposal of the cyanobacteria is a float device, where at the bottom part there are the cascade steps serving for retaining the impurities slowly gathered by the water flow into the encircled interior of the supporting float 5, where they are settled. The accumulated sediment is then used as food for animals and partly it is disintegrating at the bottom. The body of the equipment is made of plastic material so that it may be as light and as firm as possible, and at the same time may be able to float on the water. The electrodes forming the suspended electrode) are mutually interconnected and they are powered by wind power via the supply source of electric current 10—the alternator. In the vicinity of the supporting float 5, serving for holding the two types of bipolar electrodes 1 and 6 under the surface of water, quatrolysis of water is produced by mutual rotation of the electrodes 1 and 6 horizontally, in a wide range around the supporting float 5, in distinct power circles; at this process oxygen and hydrogen bubbles arising due to quatrolysis of water carry away the destroyed cyanobacteria, on the principle of electroflotation, onto the water surface, where their natural environment is changed, as a result of which the cyanobacteria do not survive. The disposal of the cyanobacteria is caused by cations and anions produced by dissociation of nitrate and phosphate molecules, inasmuch as both types of ions are unsuitable for the life of the cyanobacteria. When transporting electrical power by the electrolyte, all ions of water-soluble substances are participating in the process.

(4) They are affected by equal forces in the electric field between the bipolar electrodes 1 and 6, they are moving and transferring the electric charge also on the cyanobacteria and thus they are paralysing them.

(5) For circulation of water through the grid electrode 6, the screw water pump 2 with holes in the delivery pipe 3 is used. The water pump 2 is connected directly to the axis 9 of the equipment for utilization of wind energy. The delivery pipe 3 is connected to the water pump 2 with holes and serves for directing the movement of water required for water circulation. The outlet of the delivery tube (pipe) 3 is situated directly over the suspended electrode 1. As the result of pressure and movement of water flowing out of the delivery pipe 3, the outgoing water is flowing around the suspended electrode 1 and enhances its movement around the bipolar electrodes 1 and 6. The bottom part of the supporting float 5 is a supporting component part and may have a diameter D=from 2 to 15 m. It is actually a hollow disc made of plastic, metal and wood, having the width, for example from 600 to 700 mm and height of 500 mm. The grid electrode 6 comprises plates of sheet metal, which are situated in the lower part of the supporting float 5. They are mounted in the upper float 7, distributed evenly around the entire perimeter and connected to the photovoltaic cells 8 and alternator 10. respectively, and thus they serve as electrodes. They are placed so that they may capture even very coarse impurities, which could damage the interior of the equipment for disposal of cyanobacteria. The upper float 7 serves for fixing and interconnecting the modules of the photovoltaic cells 8. Electric power is supplied from the photovoltaic cells 8, interconnected so that safe voltage up to 24 V may be generated between the bipolar electrodes 1 and 6.

INDUSTRIAL APPLICABILITY

(6) The method and the equipment for the disposal of cyanobacteria in stagnant waters can be advantageously used for the disposal of cyanobacteria in stagnant waters, which are intended for supplying drinking water or for swimming, fish farming and there where it is necessary to ensure the quality of microlife in water and to reduce the degree of water eutrophication.
