Device for purification of sewage


FIELD: devices for purification of household and industrial sewage.

SUBSTANCE: the invention is dealt with devices for purification of household and industrial sewage and intended for electrical and cavitational treatment of sewage containing a large quantity of organic compounds. The device for purification of sewage consists of a body made out of a dielectric material partitioned by diaphragms for two electrode chambers and one working chamber, that contains a filtering material. The electrode chambers have cavitational field sources installed and the working chamber is supplied with a the bubbler installed in it. The technical result consists in an increase of recuperation of the filtering material at the expense of application of a cavitational field to it, decrease of the microbiological semination, and an increase of cavitational effect on particles.

EFFECT: the invention ensures an increase of the filtering material recuperation, decreased microbiological semination and increased the cavitational effect on particles.

The invention relates to a device for treating domestic and industrial wastewater and is designed for power and cavitation treatment of wastewater containing large amounts of organic compounds.

A device for electrodrive microorganisms /captain M.S. Microbiology of water purification. Kiev: “Naukova Dumka”, 1978, pages 207-210/, selected as a prototype, made of dielectric material and consisting of three cameras: two electrode and the average working, and as membranes serves as cellophane.

The disadvantage of this device is the low regeneration of the filtering material, the colonization of microorganisms in the environment, washable filter material when washing because imprisioning cells and the natural resistance of the filter material.

The technical result of the invention is to increase the regeneration of the filter material due to the imposition of a cavitation field, reducing microbiological contamination, as well as increasing the cavitation effect on the particles.

This technical result is achieved in that in a device for the treatment of sewage comprising a body of dielectric material separated by a membrane into two electrode and one working chamber in the electrode chamber to ascertain what s the source of the cavitation field, as well as in the working chamber is installed bubbler.

The drawing shows a diagram of the device for wastewater treatment.

Device for wastewater treatment includes a cover 1, a housing 2 made of a dielectric material, two electrode chambers 3, one working chamber 4, two electrodes: the anode 5 and the cathode 6, the two membranes made of cellophane 7, input 8 and output pipes 9 for supply and discharge of wastewater, the input 10 and output 11 connections for supply and discharge of electrolyte bubbler 12, the filter material 13, the two sources of the cavitation field 14.

Device for sewage treatment works in the following way.

Before you begin the installation for sewage treatment electrode chamber 3 is filled with electrolyte through the inlet pipe 10. Then the waste water is directed into the working chamber 4 through the inlet 8. After filling of the working chamber 4 to the electrodes 5,6 electrical current is applied, under the influence of the polarization filter material 13, resulting in several orders of magnitude increases its adsorption capacity. Under the influence of an electric field occurs immbolization colloidal and biological systems and their adsorption to the filter material 13, thus the complete purification of wastewater containing a large amount of organic ve the EU ETS. The purified waste water is directed into the pipe 9 for removal and re-use of treated water.

For continuous operation of the installation in the filter material 13 is held so many cells that they turn into a pasty mass, clogging the channels and pores, and the hydraulic resistance of the system increases to such an extent that hinders the flow of the suspension. When disconnecting the supply of electric current to the electrodes 5,6 microbial cells are released and the flow of water washed away in the form of a dense mass through pipe 9. Immbolization cells may not be able to overcome the natural obstacles of the filter material 13, so for the destruction of these complexes is the handling of the cavitation field. When switching sources cavitation field 14 outgoing ultrasonic waves passing through contaminants, the detainees to the filter material 13, under the action of surface tension forces create gaps, taking the form of bubbles. At the time of collapse of a cavitation bubble arises powerful hydraulic shock wave, which has a devastating effect on organic compounds and microorganisms. Under the action of cavitation rupture of membranes microbial cells and the destruction of its structure, as well as total loss of p is laczkovich bacteria. To enhance the process of destruction of the complexes in the working chamber placed bubbler 12, through which is supplied compressed air. Bubbler 12 is included in the time of deactivation of the electrodes 5,6 and include cavitation field 14. After completion of the regeneration process of the filter material 13 sources cavitation field 14 are disabled in the bubbler 12 stops the air supply to the electrodes 5,6 electrical current is applied, and the sewage treatment process is again repeated.

The use of this device for wastewater treatment in comparison with the prototype leads to a more complete regeneration of the filter material after use, and also to apirogennost retention of contaminants by the filter material. This device solves the problem of treatment and disposal of liquid wastes containing large amounts of organic substances.

Device for the treatment of sewage comprising a body of dielectric material separated by a membrane into two electrode and one working chamber in which is placed the filter material, characterized in that the electrode chambers installed the sources of the cavitation field, and in the working chamber is installed bubbler.
