The invention relates to automatic wastewater treatment plants and can be used in water treatment.

The purpose of the invention is to improve the quality of wastewater treatment by increasing the feed rate of the reagent.

The drawing shows a schematic diagram of the system.

To a sealed tank 1 containing reagents, summed up the pipe 2 of compressed air, which is installed regulating device 3

From the tank 1, the pipeline departs, which in turn splits into two: measuring 4, on which the level control relay 5 is installed, and drain 6, the output of which is introduced into the vacuum chamber 7. Piping 4 and 6 are two interconnected vessels. The ends of the pipes 4 and 6 are raised above the maximum possible level of the reagent in the hermetic tank 1. The dilution chamber 7 is in communication with the atmosphere through the regulator 8. The chamber 7 is unconnected. tirovan in the rupture of the Pipe Plant 9 and 10, through which the waste water is passed. From the pipeline 10, wastewater flows into the receiving tank 11, in which the sensor 12 of the chemical composition is installed, which is connected to the regulator 8.

7, the flow of the reagent occurs directly into the wastewater stream.

MAP vacuum in chamber 7 causes the outflow of fluid from the pipeline 6. This ensures high

The system works as follows.

After filling the tank with 1 re - 35 i.e. the reagent is at the minimum level, the system starts working. As far as possible from the consumer, the command of the 5-level relay, the regulating device 3 begins to increase the pressure in the tank 1, under the action of which the reactants rise through the pipe — sensitivity and increase in the speed leads 4 and 6. Relay 5 controls the reagent supply level. In addition, it is supplied and installed at the mark, the corresponding reagents in a rapidly moving stream to the current level of discharge from the sewage pipeline, limited to a small one. 6o When the reagents come to this volume of the pipe 10, provides the markers, the relay 5 through the regulating system mixing and, as a consequence, 3 stops the supply of the compressed quick reaction.

air into the tank 1. In this case, the lifting of the reactants in the pipes 4 and 6 ceases. The reagents in them are at the level of the discharge from the pipeline 6.) 0

 The necessity of introducing the measuring pipe 4 is due to the fact that the installation of the relay 5 on the discharge pipe of the formula of the invention

An automatic dosing system for wastewater treatment reagent, containing a sealed reagent tank connected to a compressed air pipeline, equipped with a dosing control level in the pipework, the drain pipe, receiving-wire 6 rises above the level of the CC) with a chemical drain sensor, those. It is poured out, and at the same time, the composition and pipeline of sewage, relay 5 gives false commands of regrel-° l and h with the fact that, with the aim of retreating device 3 for closing, at the same time, the quality of sewage treatment is

while due to the consumption of reagents from reservoir 1, the pressure in it must be raised, i.e. open the regulating device 3,

Sewage flowed along the path: pipeline. 9 - vacuum chamber 7 — pipeline 10 creates a vacuum in chamber 7 by varying the flow rate of the effluent stream. Under the influence of the vacuum, the reactants from pipeline 6 begin to drain into the chamber, where they are displaced with the waste water stream. The greater the vacuum in the chamber, the more intensively the reagent flows out of the pipeline 6, i.e. the greater the dose introduced into the wastewater. The magnitude of the dose and the degree of dilution in the chamber 7 is determined by a sensor 12 of chemical composition that acts on the regulator 8 that connects the chamber 7 to the atmosphere. With the regulator 8 fully closed, the vacuum in the chamber is maximal e and, therefore, the amount of reagent outflowing from the pipeline is also maximum. With a fully open regulating body 8, the pressure in chamber 7 is equal to atmospheric and the reagent flows out.

Due to the fact that the end of the pipeline 6, in which the reactants are at the level of the drain, is introduced into the chamber 7, the outflow of the reagent occurs directly into the wastewater stream.

MAP vacuum in chamber 7 causes the outflow of fluid from the pipeline 6. This ensures high

that is, the reagent is at the minimum possible distance from the user, the sensitivity and the increase in the reagent feed rate. In addition, the supply of reagents to fast moving wastewater, limited to a small volume of pipe 10, provides vigorous mixing and, consequently, a quick reaction.
