BACKGROUND OF THE INVENTION The invention relates to control settling tanks with showers.

The purpose of the invention is to increase efficiency by controlling the flow and clarifying it.

In Fig.1 shows a reservoir-tank of storm water, a longitudinal section; in fig. 2 shows section A-A in FIG. in fig. 3 - the same, in a perspective view; in fig. 4 - section bb in figure 2; in fig. 5 and 6 - the same, in a perspective view, with a partial cut; in fig. 7 - tray, in a perspective view; in fig. 8 - section bb In figure 2; on Lig.9 - section GG on Fig; in fig. 10 — node I in FIG.

The storm water storage tank contains a regulating cylindrical tank 1 with a conical sedimentation zone, a tangentially located supply tray 2 with a vertical chamber 3 connected to it, a sewage pipeline 4 and a spiral shape tray 5 with a grid installed along it, separating the tray 5 on Russ. The bottom rus of tray 5 is connected to the outlet tray 7 of the filtered rain drain. The flow of the spiral form 5 is adjacent to the outer side of the tank 1, provided with 8 inlets 8 inlet 9 located at the bottom of the upper rune. The stoves 9 are located in the tank around the perimeter and are equipped with water speed dampers 10 at the ends. The settling tank is also provided with a pipeline to remove sludge 11 and a siphon 12, as well as overflow holes 13 for communication of the tank 1 with the collecting trough of clarified water 14 connected to the discharge chute 7.

The lattice 6 is made with transverse slits and has a slope along the axis of Lok and to the tank 1.

The principle of operation of the settling tank is as follows. Via feed tray 2 to vertical ka. measure 3 enters the first, the most heavily contaminated dose of rain sewage immediately after the start of the shower from where it is transported

water 4 wastewater treatment plant. As the intensity increases, rainwater flows from the supply tray 2 to the spiral shaped tray 5 and then, along the tray, is further filtered through the grid 6. The filtered water is transferred to the water using the tray 7.

The clarification of the flow of rainwater in the path of movement through the separation of purified water and rainwater makes it possible to transport part of the water into the reservoir, which reduces the useful volume of the reservoir.

In order to avoid vertical agitation at the concave part of the tray 5, the grate has a transverse slope in the direction of the tank 1. The slope of the bottom of the grate 6 ensures the movement of sediment by circulation flows not up, but downward. Through the inlet 8, part of the wastewater mixture is poured into the drainage station 9 and transported into the control tank 1, and the remaining water moving along the grate 6 enters the final station 9, and then into the control clarifying tank 1, drain 9 batch, uniformly divert sludge into regulating clarifying tank 1, which allows for the gradual removal of undissolved impurities delayed by the lattice. The sinks also contribute to the uniform distribution of the retained impurities over the entire area of the living section, which increases the ebfect of clarification. Sinks 10 are installed on the sewers and the water flows through the sludge into the lower part of the sedimentation zone of the tank 1. The clarified water in the tank 1 moves upwards and through the holes 13 it flows into the collecting chute 14 and then into the tray 7. Overflow holes 13 serve as for emergency discharge and for removal of the upper, significantly clarified part of the water in the reservoir, clarified water is removed from the middle part of the tank 1 using the siphon 12.

Suspension of sediment occurs during the upward movement of water in the regulating brightening tank.

The sludge accumulates in the lower conic part of the tank 1, from where it is periodically removed by the pipe 11.
