RU2453503C2 - Apparatus for purifying sewage water - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: sewage water is fed into an electrofloatation apparatus. The electrofloatation apparatus consists of a single-chamber housing 1 and insoluble electrodes 2. There is a magnet 5 at the bottom 4 of the housing 1. During electrofloatation, foam 13 and dirt 22 is formed and hydrogen 16 is released at the cathode. Foam 13 is sucked through a socket pipe 10 into a cyclone filter 12. Hydrogen 16 is removed through a pipe 15. Dirt is removed from the cyclone filter 12 by Archimedes' screw 18. The air mixture from the cyclone filter 12 is pumped by a pump 23 through a pipe 11 into the chamber 20 of the housing, in which carbon dioxide gas 24 is also fed.

EFFECT: invention enables to purify waste water and utilise electrofloatation products.

Description

The invention relates to treatment facilities and can be used for the treatment of sewage water on an industrial scale.

A device is known as an electroflotator in which an electroflotation process is carried out. http://www.ecologistika.ru/show.php?page=408. The designs of electroflotators are quite simple. There are single-chamber and two-chamber installations, horizontal and vertical type. Insoluble electrodes are used, located horizontally or vertically on the bottom of the apparatus. The essence of electroflotation is the formation of fine gas bubbles (hydrogen and oxygen) uniformly distributed in the volume of treated water when a constant electric current is passed through an aqueous solution. Gas bubbles, rising upward, collide with dispersed particles of contaminants, adhere to them and then float them on the surface of the water, forming a stable foam layer - flotation sludge. Separate soluble contaminants physically adsorbed on dispersed particles (prototype) are also taken here.

The disadvantage is the difficulty of disposal from the surface of the formed foam and its beneficial use.

A wastewater treatment plant, including two parallel tanks, at the bottom of which aerators are installed, a compressor unit, characterized in that the aerators are installed vertically and operate on the principle of an aerial lift.

The disadvantage is the low degree of wastewater treatment.

The aim of the invention is the treatment of wastewater in sumps with the removal of pollutants with the beneficial use of electroflotation products.

The technical result in a device for treating sewage water, consisting of a single-chamber housing of insoluble electrodes, is achieved by the fact that the housing is round in shape with a roof, a magnet (electromagnet) is located at the bottom of the housing, and a cathode is vertically located in the center, and the anode is located along the round walls of the housing moreover, above the surface of the water there is a suction socket connected in series using pipes with a filter cyclone for collecting foam, and a suction pipe for In order to exit the hydrogen electroflotation product, a collecting and removing device in the form of an Archimedean screw is located in the lower part of the cyclone, and there is an exhaust pipe on the cyclone, which is connected through the roof of the housing to a cavity above the level of sewage water.

Figure 1 shows a device for cleaning sewage water.

Statics.

A device for treating sewage water (Figure 1) consists of a single-chamber housing (1), insoluble electrodes (2), and the housing (1) is made round with a roof (3), and a magnet is located at the bottom (4) of the housing (1) (electromagnet) (5), the cathode (6) is vertically located in the center, and the anode (7) is located along the round walls (8) of the housing (1), and above the surface of the sewage water (9) there is a suction bell (10) connected in series using pipes (11) with the installation of a filter cyclone (12) for collecting foam (13), and in the upper part (14) of the cyclone (12) is installed a suction pipe (15) for the electroflotation product exit - hydrogen (16), and in the lower part (17) of the cyclone (12) there is a collecting and removing device in the form of an Archimedean screw (18), and on the cyclone (12) there is an exhaust pipe (19) ), which is connected through the roof (3) of the housing (1) to the cavity (20) above the surface of the sewer water (9).

Work.

During electroflotation, a foam (13) is formed at the cathode (6), consisting of hydrogen bubbles (16) and dirt (22). Due to the large area of the anode (7), the release of atomic oxygen practically does not occur. A magnet (electromagnet) located at the bottom (4) turns the contents of the housing (1) into a “Faraday engine” (http://www.skif.biz/index.php name = Pages & op = page & pid = 120. (Unipolar engine). "Fundamentals supporting and unsupported movement ”- VI Balabay, Ivanko Yu.V.) (21) and brings, in accordance with the“ gimlet ”rule, all foam (13) into rotation around the cathode (6). A fixed suction bell (10) sucks the foam (13) into the filter cyclone (12). There, foam (13) is smeared along the walls, and hydrogen (16) is released. It is very light and immediately rises to the upper part (14) of the cyclone (12), where it is pumped out for further useful use. Dirt from the foam flows down, and it is removed from the cyclone filter (12) with the Archimedes screw (18) (screw conveyor). And the remaining air mixture passes through the suction pump (23) and the roof (3) of the housing (1) into the cavity (20) above the level of sewage water (9) in the housing (1). Carbon dioxide (24) is constantly supplied to this cavity (20) to reduce the probability of ignition of hydrogen (16).

Technical and economic indicators exceed the performance of the prototype, because additionally obtained is a hydrogen gas suitable for useful use.
