Known, selected as a prototype, "Mobile installation for wastewater treatment" [RF Patent No. 148902 U2 C02F 1/46; declared 04/29/2014; publ. 12/20/2014. Bull. No. 35], including a chamber with a reactor, sump, electrolyzer and filtration and sorption units placed in it.

The disadvantage of this installation is the low degree of wastewater treatment from microorganisms and bacteria.

The technical task and the result, which the claimed device is aimed at, is disinfection of wastewater (the destruction of microorganisms, bacteria and other compounds with high biological activity) along with the removal of suspended solids, emulsified oil products, dissolved and dispersed organic compounds, mechanical impurities, surface active substances.

The technical result is achieved by the fact that a mobile device for treating and disinfecting wastewater includes: a chamber with a reactor, a settler, an electrolyzer placed therein; filtration unit; sorption block. New, according to the proposed utility model, is that the device further comprises a decontaminator located after the sorption unit. 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. The figure 1 shows a General view of the proposed mobile device, in figure 2 - in 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 reactor and electrolyzer sections, and the lower 2 and upper 4 level gauges are placed 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; filtration unit 20; sorption unit 34, equipped at the inlet to the filtration unit and at the outlet of the sorption unit with monometers 17 and 21, respectively; decontaminator 43; collection of sludge 3; control panel 29; pipelines. All elements are mounted on a mobile trolley 25, equipped with two 36 not swivel and two 37 swivel wheels and a handle 38 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 prevent and eliminate emergencies.

A mobile device for cleaning and disinfecting 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 nozzle 39 to the mixing section 7 of the reactor, where a solution of a chemical reagent from a tank 27 is dosed at the same time through a pipe 31 by a metering pump 30 to change the pH of the medium as a result of a chemical reaction, in 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, at the same time as the wastewater enters, flocculant solution from the tank 28 is dosed through pipeline 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, wastewater through the gap between the bottom of the chamber and the lower edge of the immersion baffle 10 enters the electrolysis cell 11, where partial (more than 95%) recovery of suspended solids, emulsified oil products, dispersed organic compounds, surfactants, poorly soluble non-colored compounds 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 pump 24 through the nozzle 40 to the filtration unit 20 for deep cleaning from mechanical impurities, suspended solids, emulsified oil products, dispersed organic compounds, sparingly soluble non-ferrous and heavy metals and then through the nozzle 41 to the sorption block 34 for deep cleaning from surfactants and dissolved organic pollutants, from which waste water through line 42 enters the decontaminator 43, in which due to the low-voltage electric Critical discharge is the destruction of bacteria, microorganisms and other compounds with high biological activity. After water treatment by electric discharge, the treated wastewater is discharged from the device through a pipe 18.

The dispersed phase of contaminants that has surfaced to the surface of the water during wastewater treatment in the reactor and electrolyzer is in the form of suspended solids, emulsified oil products, dispersed organic compounds, surfactants, poorly soluble compounds of non-ferrous and heavy metals, is formed into a foam layer (slime), which moves 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 equipment placement in the device, which are interconnected by assembly operations and are in a functional and constructive unity, in which the wastewater in the reactor and electrolyzer is partially purified from suspended solids, emulsified oil products, dispersed organic compounds and surfactants, compounds of non-ferrous and heavy metals, then partial cleaning from mechanical of impurities in the sump, and then deep cleaning is carried out of mechanical impurities, suspended solids, emulsified oil products, dispersed organic compounds, sparingly soluble non-ferrous and heavy metals in the filtration unit, deep cleaning of dissolved organic compounds and surfactants in the sorption unit and the destruction of bacteria , microorganisms and other compounds with high biological activity in the decontaminator.

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

Based on the results of the experiments, it follows that the proposed design of a mobile device for wastewater treatment and disinfection allows along with wastewater treatment from suspended solids, emulsified oil products, dissolved and dispersed organic compounds, surfactants, solids, non-ferrous and heavy metal compounds, destroy bacteria, microorganisms and other compounds with high biological activity.
