Known, selected as a prototype, "Mobile installation for wastewater treatment" [RF Patent No. 161970 U1 C02F 9/08; declared 06/02/2015; publ. 05/20/2016. Bull. No. 14], including a chamber with a reactor, sedimentation tank, electrolyzer, and filtration, sorption, and anionization units placed in it.

The disadvantage of this installation is the low degree of wastewater treatment from calcium and magnesium cations, which determine the hardness of the water.

The technical problem and the result to which the claimed device is directed is to treat wastewater: softening (purification of calcium and magnesium cations) along with purification of suspended solids, emulsified oil products, dissolved and dispersed organic compounds, non-ferrous and heavy metal compounds, surface-active substances, solids, salt anions, surfactants.

The technical result is achieved by the fact that a mobile device for treating wastewater includes: a chamber with a reactor, a sump, an electrolyzer placed therein, a filtration unit, an anionizing unit; sorption block. New, according to the proposed utility model, is that the device further comprises a water softener located in front of the reactor. Moreover, all these parts of the device are mounted on a mobile trolley and are in a functional-structural unity.

The proposed utility model is illustrated by figures of drawings. In FIG. 1 shows a General view of the proposed mobile device, FIG. 2 - in the plan.

The mobile device consists of a chamber 16, with a reactor placed in it, consisting of mixing sections 7 and mixing 9, an electrolyzer 11 and a settling tank 35, while insoluble electrodes 12 are placed in the sections of the reactor and electrolyzer, and the lower 2 and upper 4 level gauges are in the mixing section level, in the sump - level gauges of the lower 22 and upper 23 levels, and in the upper part of the chamber - foam collecting device 13; tanks 27 and 28 for the preparation, storage and distribution of reagent solutions; pumps 1 and 24 for the supply of wastewater; metering pumps 30 and 32 for dispensing reagent solutions; DC power source 26; water softener 40: filtration unit 20; anionizing unit 34; sorption block 36; equipped at the inlet to the filtration unit and at the outlet of the sorption unit with monometers 17 and 21, respectively; collection of sludge 3; control panel 29; pipelines. All elements are mounted on a mobile trolley 25, equipped with two 37 non-swivel and two 38 swivel wheels and a handle 39 for moving it. Control of the movement of the device is achieved with manual pull of the handle in the right direction due to the muscular strength of the operator. The use of a mobile device will eliminate the need for laying utilities of sewage from the source of their formation (storage tanks, process baths and reservoirs, etc.) on the territory of production departments, sections and workshops of industrial enterprises to stationary treatment facilities located at a considerable distance from each other distance, and to prevent and eliminate emergencies.

A mobile device for treating wastewater works as follows. Before starting work, the device is moved to the source of formation or accumulation of wastewater. Further, wastewater containing various contaminants (table) is pumped through a water softening unit 40, which is a fitting made of polypropylene, inside of which spiral-shaped permanent magnets are placed, which help to clean calcium and magnesium cations by reducing their concentration as a result the formation of poorly soluble compounds (dispersed phase) of calcium and magnesium in the water stream into the mixing section 7 of the reactor, where a solution of a chemical reagent from the 27 n tank is dosed simultaneously through pipeline 31 asosome metering device 30 for changing the pH value of the medium as a result of a chemical reaction during which the formation of sparingly soluble compounds of heavy and non-ferrous metals, dispersed organic compounds. The intensification of the mixing of wastewater with a solution of a chemical reagent is carried out by gas bubbles of hydrogen and oxygen generated by insoluble electrodes 12.

Next, the wastewater, overflowing through the upper edge of the overflow partition 8, enters the mixing section 9, formed by the space between the overflow partition 8 and the immersion partition 10. In the mixing section 9 of the reactor, simultaneously with the flow of wastewater, flocculant solution from the tank 28 is dosed through the pipe 33 metering pump 32. A mixture of wastewater with a flocculant solution provides coarsening of suspended particles, sparingly soluble compounds of heavy and non-ferrous metals, dispersed organic compounds, coalescence of em lgirovannyh oil and surfactants. The intensification of the wastewater mixing with the flocculant solution is carried out by gas bubbles of hydrogen and oxygen generated by insoluble electrodes 12.

From the mixing section 9 of the reactor, the wastewater through the gap between the bottom of the chamber and the lower edge of the immersion wall 10 enters the electrolyzer 11, where there is a partial (more than 95%) extraction of suspended solids, emulsified oil products, dispersed organic compounds, surfactants, poorly soluble calcium compounds and magnesium, non-ferrous and heavy metals on the surface of the water mirror in the form of a sludge under the action of gas bubbles of hydrogen and oxygen generated by insoluble electrodes 12.

Further, the wastewater, overflowing through the overflow partition 14, enters through the collection pocket 15 into the sump 35, which collects mechanical impurities, as well as pollution particles, the density of which is greater than the density of water.

Wastewater from the sump through the pipe 19 is pumped by a pump 24 through the fitting 41 to the filtration unit 20 for deep cleaning of mechanical impurities, suspended solids, emulsified oil products, dispersed organic compounds, sparingly soluble non-ferrous and heavy metals, and then through the fitting 42 to the anionizing unit 34 for removal of salt anions (chlorides, sulfates and nitrates) and then through the fitting 43 into the sorption unit 36 for deep cleaning of surfactants and dissolved organic contaminants from Wastewater is discharged from the device through line 18.

The dispersed phase of contaminants that floated to the surface of the water during wastewater treatment in the reactor and electrolyzer in the form of suspended solids, emulsified oil products, dispersed organic compounds, surfactants, poorly soluble calcium and magnesium compounds, non-ferrous and heavy metals, is formed into a foam layer (flotation sludge ), which is shifted from the surface of the water mirror by the foam collecting device 13 through the overflow partition 6 into the collection pocket 5, from where the slime flows into the collection 3.

The power of the insoluble electrodes 12 located in the mixing and mixing sections of the reactor and in the electrolyzer is controlled by a constant current source 26.

The technical result in solving this problem is achieved due to a certain sequence of placement of parts of the device, which are interconnected by assembly operations and are in functional and constructive unity, in which the wastewater in the softening unit is purified from calcium and magnesium cations, in the reactor and the electrolyzer is partially cleaned from suspended solids, emulsified petroleum products, dispersed organic compounds and surfactants, compounds of non-ferrous and heavy metals it carries out partial cleaning of mechanical impurities in the sump, and then deep cleaning of mechanical impurities, suspended solids, emulsified oil products, dispersed organic compounds, sparingly soluble calcium and magnesium compounds, non-ferrous and heavy metals in the filtration unit; deep cleaning of salt anions in the anion block; deep cleaning of dissolved organic compounds and surfactants in the block.

The table shows the results of experiments on wastewater treatment using a mobile device.

Based on the results of the experiments, it follows that the proposed design of a mobile device for wastewater treatment, along with purification from suspended solids, emulsified oil products, dissolved and dispersed organic compounds, compounds of non-ferrous and heavy metals, surfactants, solids, salt anions, allows remove cations of calcium and magnesium.
