Description

The invention relates to water supply and sewage and can be widely used in disinfection of drinking and waste water with ozone. A device for ozonating water is known, which is a contact column with a water layer of about 5 m, inside which an emulsifier (low) pump jet pump is located) and a vertical pipe for supplying ozone solution to the bottom of the contact column. The duration of ozone contact with water is 4-6 minutes with a gas-water volume ratio of not more than 1: 3. The disadvantage of this device is a low ozone utilization ratio (not more than 0.7) due to the fact that the emulsifier does not provide uniform mixing of ozone solution with all volume of the processed water. In addition, it is necessary to use an engine for pressing a perforated cylinder. The closest to the invention in terms of technical drying and the achieved result is a device for ozonization of water, consisting of an orthopedic casing separated by a filter ceramic plate with a pore size of 70-80 µm for the separation of the ozone-air mixture and water and a contact column. The device is provided with a pipeline to connect the separation chamber with the contact column. The separation chamber is equipped with a feed water and ozone mixture supply pipe, and the column contact is equipped with a treated water removal pipe 2. However, the known device has a small ozone utilization ratio due to the fact that it is not possible to ensure the height of the contact chamber sufficient for both the liver and the necessary contact time to rise. ozone bubbles with treated water for 7-10 minutes. The height of the contact chamber can not be taken more than 4-5 m. In addition, the use of filtering ceramic plates with holes up to 80 MKM S1 shifts the reliability of the device due to their rapid clogging with soil particles present in the treated and, to some extent, in treated water. It is not possible to regulate the process of water treatment depending on the quantity and quality of the treated water due to the fact that the calculation of the contact chamber is made for a certain water flow and a certain amount of it. The goal of isooret is to reduce its overall dimensions and increase the utilization rate of ozone. The goal is achieved by the fact that in a device for ozonization of water, consisting of a cylindrical body, separated by a filter plate on a p separation chamber and a contacting column, a pipeline and pipes of treated water and ozone PUZ1Noy mixture and removal of treated water, is additionally equipped with an anode and cathodes made in the form of perforated Baif Hbix plates and installed parallel to the filter plate, the anode being installed above the cathodes. The drawing shows a diagram of the proposed water ozonization device, a slit. The device consists of a housing 1, equipped with a ceramic plate 2, which separates the housing 1 into an ozone-air and water separation chamber 3 and a contact column 4. In the contact column 4, perforated plates-electrodes are installed using insulating spacers 5. The electrode 6 in the upper part of the contact column is the anode, and the plates, the electrodes 7, are cathodes. The separation chamber 3 is connected to the contact column 4 by means of a pipe 8. The separation chamber 3 is provided with a pipe for supplying treated water and an ozone-gas mixture 9. At the lower part of the contact column there is a branch pipe 10 for removing treated water. The device works as follows. Through the pipe 9, the treated water, which is pre-mixed with the ozone-air mixture, is fed into the housing 1 and enters the chamber 3 of the separation of the ozone-air mixture and water. Water through the outer conduit 8 enters the upper part of the contact column 4, then passes through a system of perforated electrodes 6 and 7 and is withdrawn from the device via a nozzle Ø to remove the treated water. Bubbles of the ozone-gas mixture from the separation chamber 3 through the filter plate 2 enter the bottom of the contact chamber 4, then, lifting up, pass through a system of perforated electrode plates consisting of cathodes 7 and anode 6, which are fixed on the housing 1 with insulators 5. Ozone-air mixture bubbles, which have a certain negative electric charge, which increase when the gas bubbles contact the negatively charged contaminant particles, are subjected to a force in the contact column. nonuniform electric field obrazovan3

noro anode 6 and cathodes 7, which leads to a slower rate of their rise. The water is ozonized in a counter flow of the treated water, moving downwards in the contact chamber 4 and ozone-air bubbles. upward moving mixture. The perforated plate electrodes 6 and 7 with respect to the water being treated are the distribution system, and with respect to the ozone mixture there are additional filter plates that allow maintaining the same size of gas bubbles in the entire volume of the contact column 4.

The advantage of the proposed device over the known one is the presence of a sietema of perforated plate-electrodes, due to which the rate of ascent of the bubbles of the ozone-air mixture is measured and uniform distribution occurs in the volume of the contact chamber.

The height of the contact column is significantly reduced by reducing the speed

lifting bubbles of ozone air mixture. A decrease in the rate of rise of gas bubbles provides an increase in the contact time of ozone with the treated water without reducing the performance of the device and increases the ozone utilization rate to 0.90-0.95.

It is possible to use filter ceramic plates with a bore diameter of holes, since in the device the speed of bubbling ascends with the help of plate electrodes. This leads to an increase in the reliability of the proposed device.

The treatment of water with ozone in the contact column is regulated by varying the voltage supplied to the plate electrodes, depending on the quantity and quality of the treated water, which allows the use of the proposed device for treating bauds of different composition at different device performance.
