The invention relates to devices for the purification of water by filtration and can be used in all areas of industry where it requires water purification. A filter is known that includes a housing with a bottom, a granular charge, an intermediate bottom and nozzles for supplying initial wash water and draining filtrate and wash water C11. The disadvantage of this filter is the low quality of regeneration, since the design of the filter does not allow for efficient mixing of the layers of granular load with the rational consumption of wash water. The closest to the invention to the technical essence and the achieved result is a filter for purifying oil-containing water, comprising a housing with a crush and bottom, a granular charge, separated from a statically suspended water fraction of the polymer with a density of no more g / cm, intermediate bottom and supply of initial and flush water. The top layer of the filtering charge, saturated with oil during the water purification process, floats to the upper part of the filter. When the supply of oily water resumes, the floating granules of the granular load begin to move under the action of the flow, resulting in the oil products accumulated between them separating and pouring into the C2 oil collection chamber. The disadvantage of this filter is the implementation of flushing the oil-saturated layer of a granular load in the process of purifying oily water, as a result of which a part of the oil products, VYMYTB1X from this layer, carries the water into the bottom, without floating up the layers of the load, which reduces the quality of regeneration. The purpose of the invention is to improve the quality of regeneration of the load. The goal is achieved by the fact that a water purification filter comprising a body with a cap and bottom, a granular load made of a polymer fraction statically suspended in the polymer with a density of not more than 1.3 g / cm, an intermediate bottom and a cutting head water, drainage filtrate and flush water, provided with a vertical;: waterproof partition, attached to the bottom surface of the intermediate bottom, with a pipe for air supply, one end of which is located inside the casing between its wall and vertical hydrochloric baffle and conduit for supplying wash water to the housing diagonally opposite the pipe for supplying air. In addition, the lower edge of the vertical partition is located at a distance from the bottom of the housing. In this case, the nozzles for supplying source water and draining the filtrate are attached respectively to the lid. and the bottom of the case. The drawing shows a filter, a longitudinal section. The water purification filter consists of a housing 1 with a lid and a bottom, in which a loading grain 3 is placed on the intermediate bottom 2, made of a polymer statically suspended in water with a density of not more than 1.3 g / cm. A vertical watertight partition 4 is attached to the bottom surface of the daily bottom 2, located at a distance from the bottom of the tower 1 and forming the chamber 5, which is open at the bottom. The housing 1 is equipped with nozzles for supplying the water to be purified 6, for withdrawing the filtrate 7 dp of supplying the washing water 8 and for supplying the air 9. The filter works as follows. The nozzles 8 and 9 are arranged vertically and diagonally opposite, the nozzles 6 and 7 are along the axis of the housing 1. During the cleaning process, the water enters through the nozzle 6, passes the granular load 3 and is cleaned of contaminants. The filtrate is removed through pipe 7. As a result of the fact that the partition 4 is located at a distance from the bottom of the housing 1, it does not prevent the water from being evenly distributed over the entire cross section of the filter. When flushing the filter, industrial flush enters in a vertical direction from top to bottom through pipe 8, air from bottom to top at the firewall through pipe 9. Due to vertical watertight partition 4, air cannot be distributed over the entire cross section of the filter and passes through

granular loading only in the area separated by partition A, as a result of which large air bubbles pass through this section, causing rapid removal of discharge load 3 and water upwards.

At the same time, the downward flow of water flows through the nozzle 8, as a result of which water is circulated and loaded in the filter in the direction indicated by the arrow in the drawing, which moves it through the entire filter volume and improves the quality of regeneration. Wash water through port 7 is removed from the filter. Thus, in the proposed filter, a directed air flow is created at one wall of the filter, which displaces the granular load.

upward, causing its circulation and improving the quality of regeneration,

Attaching the nozzle for washing water to the casing diagonally opposed to the air supply nozzle facilitates the movement of the granular load from the bottom of the flushing water, which creates a directional circulation of the whole granular load inside the filter and improves the quality of regeneration. The location of the lower edge of the vertical partition at a distance from the bottom of the case eliminates the division of the cavity located under the intermediate bottom into two separate chambers, which helps to increase the quality of regeneration without complicating the automation scheme and the conditions for the discharge of purified water.
