Abstract

The invention relates to water purification devices and can be used in water supply and sewage systems. The aim of the invention is to increase the efficiency of the device and increase the degree of water purification. The device comprises a housing with water supply and discharge connections located on its opposite sides. In the case there are inclined shelves, which are electrodes, in the set.

Description

The invention relates to water supply and sewage and can be used, for example, in the treatment of natural and waste waters.

The purpose of the invention is to increase the efficiency of the device and to determine the degree of water purification.

FIG. 1 shows a proposed water purification device, a slit; in fig. 2 - the same, the connection of plate partitions with shelves. The proposed device consists of a housing 1 made predominantly of a dielectric material.

provided with a water supply pipe 2 and a water removal pipe 3. Inside the housing 1 there are perforated partitions 4, between which are installed (Tanovlen set of parallel perforated shelves 5. The latter are inclined in the downward direction, corresponding to the direction of water movement, and are connected by current leads 6 to the source of direct current 7.

The inter-shelf distance between the shelves 5 increases from bottom to top. The shelves 5 have holes 8, the size of which increases from bottom to top.

The lower surfaces of the shelves 5 are provided with hinged conductive plate partitions 9 installed perpendicular to the water flow. In case 1, a perforated pipe 10 is located between the nozzle 2 and the set of shelves 5 to remove liquid and gas. The perforated distribution partitions 4 are provided with wheels 11 and a piston 12 for their movement together with the shelves 5 inside the housing 1 along its axis. The connection plate dividers 9 (Fig. 2) is made in the form of elastic rods 13, for example, of rubber, attached to the plates 5, with a groove 14, in which the partition 9, for example, an adhesive joint, is directly attached.

The device works as follows.

Coagulated water is fed through pipe 2 into the body 1, flows around the pipe 10 and through the partition wall 4 enters the inter-arbor space formed by the system of flat shelves 5 located in the lowest position at the initial moment. When voltage is applied to the shelves 5 and, consequently, the partition 9, electrolytic gas is released — hydrogen at the cathode and oxygen at the anode. The electrolytic gas bubbles are partially through, the perforation holes 8 of the shelves 5 move upwards from the bottom up, partially move along the bottom surface of the shelves 5, which leads to the formation of a layer of suspended sediment formed from the coagulant part and soils. Gas bubbles moving along the surface of the shelves 5 are distributed in the inter-shelf space with the help of lamellar partitions 9.

Under the action of the hydrodynamic pressure of the water, the partitions 8 are rotated, the angle of their rotation being determined by the value of the water pressure and, consequently, the productivity of the device, which governs the distribution of the electrolytic gas in the inter shelf space. With the help of the piston 12, the shelf system 5 suspended layer is formed and functions in the inter-shelf space and is affected by electr

chesky floor. Water purification occurs as it passes through a layer of suspended sediment. The excess sludge enters the cavity of the conduit 10, from where it is removed. The excess electrolytic gas also enters the pipe 10 and is removed from the housing 1. The purified water is removed through the pipe 3. Periodically the shelves 5 are rinsed with a stream of water through the pipe 3.

To determine the effectiveness of the proposed device and compare it with the known, experimental samples were tested. - Under the same conditions, with the same device performance equal to 18 l / h, the experimental data obtained in the table were obtained.

 Thus, the proposed device provides a higher water purification effect than the known one, according to the main indicators of water quality.

The advantages of the proposed device in comparison with the known ones are as follows. The design of the device, characterized by E1a with the location of the shelves - electrodes with a downward slope in the direction corresponding to the direction of water movement, ensures the purification of water in the layer of suspended sediment. The possibility of Moving the shelf system of electrodes in the housing creates conditions for applying an electric field to the layer of suspended sediment and activating it.

Making the perforated shelves and arranging them with increasing inter-shelf distance from the bottom up allows creating equally optimal conditions for water treatment with electrolytic gas in all inter-shelf shelves and at the same time reducing the total number of shelves - electrodes, which leads to a decrease in power consumption.

Articulated baffles - electrodes ensure the distribution of electrolytic gas in the inter-shelf gaps, which makes it possible to create optimal conditions for the formation of a layer of suspended sediment maintained continuously by removing excess sludge and electrolytic gas using a perforated pipeline.

Thus, the proposed device is more efficient compared to 516.

known and allows to significantly increase the degree of water purification.
