Description

The invention relates to a technology for cleaning artificial man-made reservoirs located in any climatic zone, including the Arctic, and is intended for water purification both in the surface layer and in a layer of a certain thickness, at the point of water intake for technical needs without transporting it to water treatment facilities .

The currently existing methods and means are intended mainly for cleaning the surface, bottom and side surfaces of reservoirs, and devices for complex cleaning of the surface layer of water are extremely insufficient. From the prior art there are various technologies and equipment used for water purification in reservoirs, the diversity of which is due to various technological and economic factors.

A device is known for removing the surface layer of oil-containing liquids, containing a floating oil-collecting means in the form of a belt conveyor with an endless belt of oil-resistant material perforated on the sides, which can be used in water supply and sewerage treatment facilities, in the chemical and metalworking industries, when cleaning technological, lubricating and coolants from organic impurities, as well as to collect oil products from the surfaces of reservoirs of rivers, lakes, seas and oceans. The principle of operation of the device is that after the ascent of oil products to the surface, in particular the settling tank, or to the surface of reservoirs, the floating oil sump sinks to the surface of the liquid, the belt perforated on the sides is set in motion by means of a drive and sprockets, oil products stick to the surface of the belt , where the walls of the scrapers are removed and discharged into a tank for the accumulation of oil products (RF Patent No. 2712569 C1, priority date 03/04/2019, publication date 01/29/2020, authors: Karev E.A. et al., RU).

The disadvantages of the known device are: limited use, due only to the collection of oil products, difficult maintenance of the device and the problem of disposal of oil products from the surface of the tape.

There is a known method of removing organic film from the surface of a reservoir, which can be used when cleaning and maintaining the surfaces of open reservoirs, including rivers, lakes, seas and oceans, from oil spills from tankers or pipelines. The method consists in applying a sorbent in the form of particles to an organic film on the surface of a reservoir, and the sorbent used in the method is incandescent silica particles in the form of sand heated to a temperature of 100-1700°C (RF Patent No. 2487974 C2, priority date 20.07.2010 , publication date 20.07.2013, author Zhdanov V.I., RU).

The disadvantages of this method are high energy consumption for heating the sand, as well as inefficiency at low temperatures of the ambient air and treated water.

Known installation for cleaning the surface of the water, which can be used to remove oil and oil films from the surface of the water, including a platform, an electric motor, a gearbox, a rotating cylinder with pressure rollers, as well as containers for collecting oil or oil, and the pressure rollers are made of smaller diameter, than a hollow rotating cylinder, and pressed against it from the outer and inner sides, while the rotating cylinder is partially immersed in water at a small angle with the possibility of adjusting the immersion depth, and the installation is equipped with a windmill (RF Patent No. 2483164 C2, priority date 02.06.2010, date publications 05/27/2013, authors: Pimshtein P. G. et al., RU).

The disadvantage of this installation is its low performance, as well as limited functionality.

As a prototype, an oil-garbage vessel in the form of a catamaran with pontoons as floats is adopted, on which the supporting structure is fixed with a superstructure and cleaning equipment located on it, containing a control point for the movement and the cleaning process, cushioning bumpers, carriages for hoists, a container for collecting garbage, a container for oil recovery, outboard engine, propeller and propeller attachments. The operation of the device is carried out when the vessel is moving at a very low speed. In this case, the propeller is transferred to the working position for collecting oil, in which the nozzles on the propeller are closed around it. Contaminated water passes into the inter-float space and enters the treatment device. At the same time, contaminated water passes successively the stage of cleaning from debris and solid objects in the tank, due to filtration through a metal mesh, and the stage of cleaning from oil pollution in the threshold-type oil-gathering system by separating the surface layer into a separate tank (RF Patent No. 154468 U1, priority date 02/19/2015, publication date 08/27/2015, authors: Matsenko S.V. et al., RU, prototype).

The disadvantages of the prototype are: the limited functionality of the device due to the lack of the possibility of complex water purification in a man-made reservoir, as well as the low efficiency of water purification from oil products in a threshold-type oil gathering system.

The technical problem to be solved by the claimed invention is the creation of a mobile device for complex water purification in a man-made reservoir, which has the ability to carry out water treatment in the device itself for using water at the point of abstraction for technical needs and improving the water quality of the reservoir with purified water, as well as effectively operating, including in the Arctic region.

To solve the technical problem, a mobile device for complex water purification in a man-made reservoir is proposed, containing purification equipment installed on a catamaran-type watercraft and a control point for the movement of the watercraft and the purification process. What is new is that the craft is equipped with a carrier deck with sides, in the front part of which a sorption boom is fixed in front of the craft, which is a perforated pipe with Unisorb-BIO filler and is designed to collect oil products from the surface of the reservoir. On the deck there is equipment for the intake and sequential treatment of water, containing a water intake device with a protective grate and an ejector, installed with the ability to move into the depth of the reservoir and connected to a pump designed to lift and supply water to a vertical sump located in series on the deck with a built-in laminar module, block of clarification filters with loading of Unisorb-BIO sorbent, pump, block of sorption filters with loading of gliezh and purified water tank with ultraviolet lamps installed in it and outlet for consumer and discharge of purified water into the reservoir. In addition, the boat drive and battery are located on the deck.

According to the invention, the water intake device contains a flexible rubber-fabric pipe wound on a drum installed on the deck of the watercraft.

According to the invention, the device contains blocks of clarification and sorption filters in the form of replaceable block modules.

The essence of the invention is illustrated by drawings, where figure 1 schematically shows a mobile device for complex water treatment in a man-made reservoir, General view; figure 2 - the same, front view.

The inventive mobile device for complex water treatment in a man-made reservoir contains a catamaran-type watercraft 1 with a carrier deck 2, for example, a frame type and sides 3. A water treatment complex of interconnected treatment equipment is placed on the watercraft for the implementation of physical-chemical and biological water treatment, as well as the collection of purified water with the possibility of its withdrawal and use for technical needs and improvement of water quality indicators of a man-made reservoir. At the same time, a sorption boom 4 located in front of the floating craft is fixed in the front part of the deck, which is a perforated pipe with Unisorb-BIO filler and is designed to collect oil products from the surface of the reservoir. On the deck of the craft there is equipment for the intake and sequential treatment of water. The water intake device 5 contains a flexible rubber-fabric pipe with a nozzle in the form of a protective grid 6, installed with the possibility of moving into the depth of the reservoir with the help of a drum 7 installed on the deck of the watercraft. an ejector for lifting and supplying water to the cleaning devices arranged in series on the deck and interconnected by a pipeline: a vertical sump 10 with a built-in laminar module 11, a clarification filter unit 12 with loading of the Unisorb-BIO sorbent, a pump 13 supplying water to the sorption filter unit 14 with loading gliezh, and a tank of purified water 15 with ultraviolet lamps 16 installed in it and an outlet 17 for the consumer and the discharge of purified water into the reservoir. In addition, the drive 18 of the craft, the battery 19 and the control center 20 are located on the deck.

A mobile device prepared for operation for complex water purification in a man-caused reservoir, containing a catamaran-type watercraft 1 with a water treatment complex placed on it, is placed in a reservoir and begins to slowly move along the water surface. Attached to the side walls of the front part of the deck of the craft, the sorption boom 4, which is a perforated pipe filled with Unisorb-BIO sorbent, moves in front of the craft, collecting and sorbing oil products from the water surface. Simultaneously with the start of the movement of the device, the flexible rubber-fabric pipe of the water intake device 5, wound on the drum 7 with a nozzle in the form of a protective grid 6, is lowered into the reservoir by winding from the drum to a selected depth of not more than 2 m. Using the ejector 8 and the pump 9, water enters the vertical sump 10 with a laminar module 11 installed, designed for uniform distribution of water entering the device, where water is partially clarified and the content of suspended solids and the total microbiological number are reduced. After the sump, water flows by gravity to the block of clarification filters 12, where sorption purification of water takes place through the Unisorb-BIO sorbent from suspended solids, emulsified oil products, biopollutants and a decrease in the level of iron, turbidity and color of the purified water. After being cleaned on clarification filters, the water is pumped by pump 13 to the block of sorption filters 14 with a load of gliezh, where sorption cleaning takes place, providing a significant reduction in a whole range of water quality indicators, such as: color, oxidizability, hardness, total mineralization, iron content, oil products, suspended solids, nitrites, nitrates. After sorption purification, water enters the purified water tank 15, where it is exposed to ultraviolet radiation from ultraviolet lamps 16 and disinfected. From the tank 15, purified water, in the absence of water intake, is returned to the reservoir through the outlet device 17 to improve the water quality indicators. The control point 20 controls the movement of the craft and the cleaning process. The device provides for the possibility of periodic replacement of sorption loads and timely replacement of block modules 12, 14.

The advantages of a mobile device for complex water treatment in a man-made reservoir are as follows:

- in a simple structural diagram of the device and the configuration of the equipment included in it;

- in the use of sufficiently cheap sorbents;

- in the absence of the need to transport water to water treatment facilities, which is ensured by water purification inside the device;

- in versatility, since the mobile device has the ability to purify both the surface of a reservoir and a layer of water of a certain thickness, as well as to accumulate purified water inside the device in a reservoir of purified water or discharge purified water into a reservoir.

- in the possibility of using the device, including in the Arctic zone, due to the use of sorption materials Unisorb-BIO and Gliezh, which work effectively at low temperatures of the treated water.

The technical result achieved by the invention is to combine water purification in a man-made reservoir and water treatment for technical needs while reducing energy and labor costs.
