Abstract

Usage: for water purification in water treatment plants, preparing water for household and drinking and industrial needs. SUMMARY OF THE INVENTION: a filter comprises a filter loading housing, a hydraulic elevator, and a filtrate collecting means. A conical reflector and a funnel with a conical wash water distributor are installed in the loading washing chamber. Means for collecting the filtrate are made in the form of a porous truncated cone placed under the housing cover and a porous reverse truncated cone in the pipeline for supplying source water. 1 ill.

Description

FIELD OF THE INVENTION This invention relates to water purification devices and can be used in wastewater treatment plants that prepare water for potable and industrial needs.

The purpose of the invention is to improve the quality of water treatment and washing of the load. , The drawing shows a section of the filter - - - g. ;,. ,. y, - ;;.:: The filter consists of a cylindrical body 1 with a cone-shaped bottom filled with a filter load 2, a distribution system of source water 3, a drainage system for collecting the filtrate 4, there are washing chambers for the filter load 5, hydraulic elevator 6, as well as pipelines of the source water 7 , clarified water 8, supply of wash water 9 and drain of wash water 10. The distribution system consists of two sections. One section is located on the inner surface of the conical bottom above the distribution chamber of the source water 11, and secondly above the baffle plate 12 of the central distribution chamber 13. The distribution system is made in the form of: a louvre grille. Drainage system j; filtrate collection is located in the upper part of the filter and consists of porous elements 14, for example, polymer concrete, and collection chambers 15.

. The washing chamber of the filter load includes a slurry line 16, a conical shield: 17, a funnel 18 with a conical distributor of washing water 19 and a chute for collecting washing water 20.

The filter works as follows, v Processed water, after preliminary. After clarification or mixing with the reagents, it passes through a pipe 7 to the source water chambers 11 and 13, from which it goes through the distribution system 3 to the lower loading layer. At the same time, flushing water is supplied to the elevator

having beaten the washing chamber to the cone distributor 19. The clarified water, filtered, rises, is collected by the drainage system 4 and is discharged through the pipeline 7 to the second cleaning stage or to the clean water tank. The contaminated filter charge is taken from the bottom of the filter by the hydraulic elevator b and fed through the slurry line 16 to the washing chamber RU5-V: ..:, v ...-.;.,; : -; Ch. ;

A mixture of sand and water flows above. The bulk water is poured over the edges of the chamber into the chute 20 and is discharged through a pipe 10 to a drain. The sand, hitting the conical shield 17, slides along it and falls into the pre-flush funnel 18, into which flushing water is supplied through the cone distributor 19 to enhance the washing effect of the charge. The contaminant wash charge returns to the top of the filter.

The value of the pressure loss in the filter loading layer at a given filtration rate remains constant and depends on the load size, suspension in water and the rate of continuous selection of the filter load for washing. Thank you
