METHOD FOR THE DISPOSAL OF SINCINES IN STANDING WATERS AND THE EQUIPMENT FOR ITS ACTIVITY

Technical field

The technical solution relates to a method for the disposal of sine in stagnant waters of lakes and dams by the quatrolytic method and to equipment intended for their disposal.

BACKGROUND OF THE INVENTION

The proliferation of sine and algae in stagnant waters, called eutrophication of waters, is a global problem, primarily because sinium vegetation secretions are toxic.

Currently, biological-mechanical float construction devices designed for biological reduction of phosphorus and nitrogen content in water by cultivation of special aquatic plants are used for the disposal of sine in still waters of lakes and dams. The disadvantage of these devices is low efficiency, care for plant growth and limitations to the vegetation period of plants - E 10822, WO2009030977 (A2) _.

Also known are devices for sine destruction by mechanical means, on the principle of dredging of the bottom of reservoirs from shores, or by boat dredges. This technology is expensive and has only a short efficiency since sine reproduction is dependent on the phosphorus and nitrogen content of the water, which these devices do not remove - FR20000000046, FR2791947 (A3).

Also technologies based on chemical or biological principles using dispenser principle devices - WO9938810 (A1) are used. However, sinium destruction by water chemistry destroys biological life in its entirety, thus also affecting macro-life. The most common way of limiting the growth of cyanobacteria in reservoirs is by applying toxic substances to cyanobacteria and algae - using algicidal or algistatic substances. Although the advantage of this method is the relatively simple application, time-consuming nature, it is not possible to determine in advance whether such intervention will be effective, environmentally friendly and economically advantageous.

Eating sinus with natural predators is rare and is limited, for example, to the use of cyanophage viruses, as well as bacteria such as actinomycetes, flexibacterium, which disrupt the cyanobacterial cell wall, prevent photosynthesis, but the secondary effects of which are unexplored. The use of algae, fungi and protozoa also distorts the overall biodiversity of water and is not effective - DE19731309 (A1).

Also known is the cavitation method for the disposal of sine from the bottom of tanks.

SUMMARY OF THE INVENTION

The above-mentioned deficiencies are eliminated by a technical solution which is based on a combination of the method of disposal of sine in still waters and equipment for its implementation.

The device consists of a float construction that serves to keep two types of electrodes below the surface of the water. The electrodes are placed in the water above each other and are bipolar. The top electrode is a system of anodes and cathodes, and the bottom electrode is also. The lower electrode multiplies the effect of electrolysis, resulting in quatrolysis - similar to the electron tube grid, affecting the electron flow. Between the electrodes, quatrolysis occurs in a wide circle around the float in distinct ring circles, thereby multiplying the effect of the electrovoltaic flotation effect on sinus depletion. By transferring an electric charge to water, the flux rings create a malignant environment for cyanobacteria.

In the lower part of the device body there are cascade steps, which are used to collect impurities that slowly settle in the device by water flow. The sediment then serves as animal feed and partially decomposes on the bottom.

The sine disposal device comprises at the same time a power generating device, a rotary source and photovoltaic cells for supplying electrodes with direct current through the alternator. It also includes a device for the use of wind energy, which may be e.g. in the form of a wind propeller, motor, impeller or air turbine, and which drives a rotary DC power source, as well as a screw pump that accelerates the movement of water within the circular float, and drives a rotary DC power source

The quatrolytic sine disposal method is a multiple-effect electrovoltaic electroflotation method, i. water purification by accelerating the natural self-cleaning effects of different electrical potentials in the water and flotation, that is to say, by carrying out oxygen and hydrogen bubbles generated by water electrolysis. Water molecules are decomposed, hydrogen is excreted at the cathode, oxygen at the anode. The oxygen and hydrogen bubbles formed by quatrolysis of water carry the destroyed cyanobacteria also on the principle of electroflotation to the surface of the water surface where they change their natural environment and the cyanobacteria do not survive. Moreover, water contaminated by cyanobacteria, algae and bacteria in the wide range of quatrolysis prevents intermembrane nutrient exchange by a single cell organism and also increases the gas content of cyanobacteria, which brings them to the surface.

During quatrolysis, mineral salts dissolved in natural lake water decompose into positively charged metal ions - cations of calcium, magnesium, potassium, sodium, heavy and other metals, and acid residues with a negative charge of chlorine, sulfur, phosphorus, partly nitrogen, etc. - anions. The water around the device, produced by the quatrolysis process, acquires new features, especially when the special equipment of two types of electrodes - pendant and grid electrode - is used. The two waters produced, both alkaline and acidic, thus acquire completely different properties, which are able to maintain for a certain period of time and are unsuitable for the life of sinus.

Cations and anions formed by dissociation of soluble substance molecules, nitrates and phosphates are unsatisfactory for sine life. Both types of ions are subject to the same forces between the electrodes in the electric field, moving and transmitting electric charge to cyanobacteria, thereby paralyzing them. Electrolyte transport involves all of the lake water ions as an electrolyte, so they carry part of the current over a wide circuit, and the method is therefore effective both inside and outside the electrodes.

DETAILED DESCRIPTION OF THE INVENTION

The stagnant sine disposal device consists of a carrier float 5 in the form of a hollow closed cylinder in which a rib 4 is guided transversely. On it is mounted a wind energy recovery device 9 which drives the water pump 2 housed in the discharge tube 3 and the electric power source. The upper carrier part of the device floats the shape of the carrier float 5, is of dielectric, light, floating material and serves to anchor the grid electrode 6 as a set of electrodes radially spaced. Photovoltaic cells 8, interconnected with bipolar electrodes 1 and 6, are disposed on the upper float 7. The alternator 10 also supplies the bipolar electrodes 1 and 6 with direct current. A suspension electrode 1 is suspended on the device web 4, connected to electrical power sources 8 and 10. The carrier float body 5 of the sine disposal device is a float device where cascading stages are located at the bottom to collect impurities that flow through the water in they slowly collect into the inner enclosed space of the carrier float 5 and later settle. The deposited sediment then serves as animal feed and partially decomposes at the bottom. The body is made of plastic to make it as light, rigid as possible and at the same time to float in water. The electrodes forming the suspension electrode 1 are interconnected and are supplied with wind power through the alternator 10. In the vicinity of the carrier float 5, which serves to keep the two types of bipolar electrodes 1 and 6 below the surface of the water, water is quatrolyzed in a wide circle around the carrier float 5 in distinct ring circles, the oxygen and hydrogen bubbles formed to the surface of a water surface where their natural environment and cyanobacteria do not survive. Sulfur destruction is caused by cations and anions formed by dissociation of nitrate and phosphate molecules, both of which are unsuitable for sinus life. In electrolyte transport, all the water-soluble ions that are subject to the same forces in the electric field between the bipolar electrodes 1 and 6 move and transmit the electric charge to the cyanobacteria, thereby paralyzing them.

A screw water pump 2 with openings in the discharge tube 3 is used to circulate the water circulation through the grid electrode 6. The water pump 2 is connected directly to the axis of the wind energy recovery device 9. The discharge tube 3 is connected to the water pump 2 through the openings and serves to guide the movement of the water required to circulate the water. The outlet of the discharge tube 3 is directly above the suspension electrode L The pressure and movement of water exiting the discharge tube 3 causes the outgoing water to flow around the suspension electrode 1 and improve its movement around the bipolar electrodes of the rope. D = 2 to 15 meters. It is actually a hollow disc of plastic, sheet, wood, for example 600 to 700 mm wide, 500 mm high. The grid electrode 6 consists of sheet metal plates which are embedded in the lower part of the carrier float 5. They are fixed in the upper float T, uniformly distributed over the entire circumference, connected to the power sources 8 and 10 and thus serve as electrodes. They are stored so as to retain very coarse dirt that could damage the interior of the sine disposal facility. The top float 7 serves to fasten and interconnect the modules of the photovoltaic cells 8. Electricity is drawn from the photovoltaic cells 8, connected so as to create a safe voltage between the bipolar electrodes 1 and 6, up to 24 V.
