The invention can be used for restoration of soil and vegetation land use neutralized sludge sludge treatment facilities, and water treatment for industrial-commercial activity, for example for irrigation of non-food crops.

A known method of purification of wastewater by electrocoagulation using AC, which include movable electrodes, and the process is conducted at a current density of not lower than 3.0 a/DM2(EN 2071449).

However, this method cannot provide high performance processing waste, because the use of two phase alternating current has the disadvantage of incomplete use of electricity electroreactive three-phase current, resulting in the cleaning process are observed unproductive electroputere reducing device performance due to incomplete use of the electrical supply. Also this method does not provide running clearance.

Known electrolysis of water, comprising a housing, two communicating through openings on the side surface of the tubular vessel, equipped with nozzles mounted on the bottom base chassis, and electrodes connected to the source of supply. Tubular non-current carrying capacity mounted coaxially and closed General the mi flanges, that fixed peripheral ties grounds housing. This device is intended to treat the water in the channel (EN 2165894).

However, it cannot be used to neutralize a wide spectrum of industrial waste.

Known cell-Converter dissociated contaminant containing tubular body of tokoprovodyascheho material and the electrodes mounted in the housing and connected to a source of multiphase alternating current (EN 2221754).

However, it cannot be used to neutralize a wide spectrum of industrial waste, because the materials of the electrode and insulator are selected based on the properties of the processed waste. And for this it is necessary to provide conditions for rapid replacement of the working parts. Another disadvantage is the inability to work on the channel.

The technical result provided by the invention, is to improve performance by running the cleanup of contamination, as well as to simplify the operations of replacement of the electrodes depending on the type neutralizing waste.

This technical result is ensured by the fact that the cell-Converter dissociated contaminant comprises a tubular body made tokoprovodyascheho material and the electrodes mounted in the housing and connected to AC mn is gianugo current. The body is made of segments that are adjacent to one another with the formation of the tubular element, the inner surface of the tubular element at the input is narrowing, and the output cone, the electrodes are mounted in the sectors or between sectors in the direction of movement of the purified stream and sectors tight end tapered sleeves.

The education corps of the individual segments provides high maintainability of the cell, as well as a quick replacement of the electrodes.

The shape of the inner surface of the housing provides high-speed driving waste and therefore increase performance.

The invention is illustrated by drawings, where shown on:

Fig.1 - cell, front view;

Fig.2 - cell, side view;

Fig.3 - cell, side view in section;

Fig.4 - cell, type in ISO;

Fig.5, 6 - cell, in the form of a pipe.

The proposed cell-Converter works by rearrangement of chemical complexes in a more durable connection, when exposed to an alternating current with variable field strength or the specified exposure time. The high efficiency is the stoichiometric balance of oxidants and reductants. The cell is distinguished by the use of alternating current with the changing intensity and exposure time.

Design the construction and principle of operation of the electrolyzer. Liquid industrial waste flowing through the cell, exposed to single-phase or polyphase alternating electric current passed through the electrode 1 located in the insulating segment 2. It should be noted that the material contacts and insulators are selected based on the properties of the treated fluid. In the segment electrolyzer all segments are held due to the taper crimping end sleeves 3, 4 and tightened the bolts 6. The electrodes are powered via pin 5. It is possible to provide the casing 8, the indicator 9, the necessary accession of 10 and an electric and/or erosion protection of piping and equipment installation earthed screens 11.

All items are sealed and connected in a single case.

The electrolyzer can be made in the form of a one-piece insulated pipe 7.

Does the cell in the usual way.
