FIG. /

The invention relates to devices for the purification of water by filtration and can be used in various fields of industry and agriculture, in particular, in the preparation of natural water for drinking and industrial water supply.

Known is D1: an air filter for cleaning natural and sewage waters, comprising a housing with falling and tapping branch pipes located in a housing in the upper russa granular. filter loading, the grain density of which is lower, the density of water, and in the bottom - a heavy granular load, between the dachas there is a device for collecting and discharging wash water l i

This filter with a small area has a significant height and the upper movable filtering granular layer.

Most; Close to the invention is a water purification filter comprising a body with a granular load, devices for supplying, collecting and draining a liquid, obliquely mounted partitions dividing the body into two expandable chambers, one of which is filled with a granular load whose density is less than density. cleaned liquid, and another granular load, the density of which is greater than the density of the cleaned liquid 2.

A disadvantage of the known filter is that there is a movable loading layer which, when the filtration rate increases or its earnings do not ensure the required quality of the filtrate. In addition, with a small height, the filter has a significant cross-sectional area.

The purpose of the invention is to improve the reliability of the filter in operation by preventing the mobility of the loading grains in the water purification process while at the same time increasing the compactness of the structure.

The goal is achieved by the fact that in a water purification filter comprising a housing divided by a waterproof partition into two chambers, one of which is filled with floating and the other with heavy granular loads, the partition is made zigzag and mounted horizontally, and the floating load is placed in the lower chamber .

Tsa FIG. 1 shows the device. for water purification, top view in FIG. 2 shows section A-A in FIG. one.

The device consists of a housing or tank 1, divided by a zigzag partition 2, filled with a heavy granular load 3 and floating polystyrene 4, on the Rus. In the recesses of the partition 2 there are drainage branches 5 connected to

 to a collector 6, to which the CONNECTIONS pipelines 7 for draining the filtrate and 8 washing water approaches, is located in the upper part of the tank 1 there is an upper drainage system 9,

О to which the pipelines 10 and 11 are connected to supply the source water and discharge the wash water, respectively. The lower part of the tank 1 is equipped with a bottom drainage system 12, to which is connected

pipelines 13 and 14 for supplying is. water flow and removal of wash water, respectively.

The device is working next

0 way

The source water through pipelines 10 and 13, respectively, flows into the upper and lower drainage systems 9 and 12, evenly distributed

5 through the area of the tank 1 and two oppositely directed flows rushes to the drainage branches m. 5. The descending stream from the drainage system 9 passes through a heavy load 3 and the upward flow from the drainage system 12 passes through the floating load 4. The filtered water is collected in another with waste connections 5B, the collector 6 and through the pipeline 7 are diverted to the consumer;

5 After contamination of loads 3 and 4, supply of source water through pipelines 10 and 13 is blocked, and filtrate is drained through pipeline 7. Pipe 8 is supplied with flushing of water to collector 6 and drainage branches 5, flushing of heavy and floating loads is carried out alternately. To do this, first open the valve on the pipe 11,

5, the flushing water from the drainage response of the 5 enters the heavy load 3, expands and launders it, rises upwards, where the draining system 9 collects and is withdrawn through the pipe 11. After flushing the quartz load, the valve on the pipeline 11 closes and opens valve on the pipeline 14. Flush. the water from the drainage branches 5 goes to the floating load 4, passes it from top to bottom, expands and launders the load, is collected by the drainage system 12 and is discharged through the pipeline 14. The flushing ends by flushing

0 on pipelines 8 and 14.

The advantage of the proposed filter in comparison with the known one is that the placement of a floating 5 and heavy granular loads in a zigzag-shaped, waterproof, horizontal partition allows. perform double stream filtering to provide filtering in the direction of increasing the loading size, thereby preventing the load from moving and increasing the filtering speed to 12-15 m / h. The arrangement of the floating and heavy granular loadings into the zigzag, waterproof waterproof partition provides, in comparison with the well-known filter, the reduction of the cross-sectional area of the filter.
