RU216051U1 - FAST FILTER WITH AERATOR FOR WATER CLEANING - Google Patents

Abstract

A quick filter with an aerator for water purification is designed to purify natural and waste water from suspended solids, in particular in water supply systems of settlements and industrial enterprises, in industrial wastewater systems. The device consists of a hollow body equipped with purified water outlet and wash water outlet, inside the hollow body a supporting layer is filled, in which a drainage system is installed, connected to the water outlet pipe, and an aerator, which is located under the drainage system, two bipolar electrodes, between which the filter load is filled. The device makes it possible to provide an environment for aerobic biodegradation of pollutant components.

Description

The utility model is intended for the purification of natural and waste waters from suspended solids, in particular in water supply systems of settlements and industrial enterprises, in wastewater systems of industrial enterprises.

A device for wastewater treatment (A.S. USSR 835971) is known, containing a housing with aeration and clarification pockets, an aeration unit and technological pipelines, and above the water level in the housing, a water distributor and a grate made of separate removable blocks are located one above the other.

The disadvantage of this device is that it does not have a filter load.

Known for Quick Filter Pat. RU 128510 U1 RF, Quick filter B01D 24/00 (2006.01), / Aleshin V.C., Aleshin A.V., Onishchenko A.A.; applicant and patentee Aleshin VS, Aleshin A.V., Onishchenko A.A., Federal State Budgetary Educational Institution of Higher Professional Education "Rostov State Construction University" (RU). - No. 2012141858/05; dec. 01.10.2012; publ. 05/27/2013], containing a housing with a filter bed made of crushed porcelain and a layer of polymer concrete supporting it. The body is equipped with a pocket with an inlet pipeline, an outlet pipeline and gutters. In the lower part of the housing there is a drainage device with an outlet pipeline for filtrate removal and an inlet pipeline for supplying wash water.

The disadvantage of this device is that it does not provide an environment for aerobic biodegradation of pollutant components.

The closest analogue is the Rapid filter for water purification [US Pat. RU 88346 U1 RF, Quick filter for water purification C02F 1/465 (2006.01), / Nazarov V.D. Nazarov M.V.; applicant and patent holder State educational institution of higher professional education "Ufa Petroleum Technical University" (RU). - No. 2009119169/22; dec. May 20, 2009; publ. November 10, 2009] containing a housing, water inlet and outlet pipes, wash water inlet and outlet pipes, a lower drainage system, a chute for collecting wash water, a filter load and a supporting layer. In the filter media, rod electrodes made of electronegative and electropositive materials are placed vertically in the form of alternating rows, the electrodes being placed in a checkerboard pattern.

The disadvantage of this device is that it does not provide an environment for aerobic biodegradation of pollutant components.

The technical result of the proposed device is to provide an environment for aerobic biodegradation of pollutant components.

The technical result is achieved by the fact that the device consists of a hollow body, equipped with pipes for the removal of purified water and the removal of wash water, a supporting layer is filled inside the hollow body, in the volume of which a drainage system is installed, connected to the water outlet pipe and an aerator, which is located under the drainage system, in In the hollow body, two electrodes of different polarity are fixed, between which the filtering load is filled.

In FIG. 1 shows a general view of the device.

The device consists of a hollow body 1, to which a purified water outlet pipe 5 and a wash water outlet pipe 6 are connected. A support layer 8 is filled inside the hollow body 1, in the volume of which a drainage system 3 is installed, connected to the water outlet pipe 5, and an aerator 4, which is located under the drainage system 3. In the hollow body 1, two electrodes of different polarity are fixed, between which the filter load 7 is filled (see Fig. 1).

The device works as follows. The purified water is supplied to the hollow housing 1 of the rapid filter with an aerator on top. A potential difference arises between the electrodes of opposite polarity 2, due to which an electric field is created and the coagulation process begins. Particles of pollutants are retained in the filter media 7, the aerator 4 saturates the water with oxygen and provides an environment for the aerobic biodegradation of pollutants, and the water, passing further through the supporting layer 8, is additionally purified, clarified and discharged through the purified water outlet pipe 5. For washing the quick filter with an aerator include a reverse flow of water. Water is supplied through the purified water outlet pipe 5 and, rising up, entrains particles of pollutants and is discharged through the wash water outlet pipe 6.

Claims (1)

A quick filter with an aerator for water purification, consisting of a hollow body equipped with pipes for discharging purified water and discharging wash water, a supporting layer is filled inside the hollow body, in which a drainage system is installed, connected to the water outlet pipe, and an aerator, which is located under the drainage system, two bipolar electrodes are fixed in the hollow body, between which the filtering load is filled.
