a stuffy mixture through a filter absorber when filling the tank with wastewater; figure 9 is a perspective view of a system for supplying wastewater to a tank; in Fig. 10 is a graph of the function (K) and the working formula for determining the volume of the regulating capacity of WeMK as a function of the coefficient of hourly unevenness of the flow of wastewater (K),

The tank 1 is reinforced concrete, rectangular in plan, used as a regulating tank, contains the following elements:

pipeline 2, which supplies wastewater to the tank, gallery 3 valves, feed systems in the tank, pipes 4, feed into each tray of the tray part of the tank bottom, nozzles 5 at the end of the pipe supply to the tray, emptying tray 6 in the tray part of the tank bottom, laid with slope towards the empty side, empty section 7 of the tray part of the tank bottom, a transverse vertical partition 8 installed at the end of the tray part of the tank bottom, a culvert 9 in the transverse partition above the gate section, the gate section 10 at the end of the tray, drainage collection channel 11 after the tray part of the bottom, receiving at a hole 12 for the tank drain pipe, tank drain pipes 13, overflow pipes 14, gate section control column 15, vertical longitudinal partition 16, filter absorber 17 for purification of the gas-air mixture displaced from the tank when it is filled, pipelines 18 that allow air to enter the tank when it is empty, pipelines 19 for removing gas-air mixture from the tank, air intake swarm 20;

Waste water is supplied to the tank 1 by a pipeline 2, which enters the gallery 3 of valves and is supplied to each emptying tray 6 through nozzles 5 of the pipe feeding into the tray 4. Such a wastewater supply system allows controlling the flow rate entering the tank with a small step of changing it quantities. Section gate 10 - in the closed position.

When the reservoir is filled, the gas-air mixture is naturally displaced from it through the piping system 19, through the filter-absorbers 17 and the air intake device 20. In the event of overfilling of the reservoir 1, waste water is discharged through overflow pipes 14.

The emptying of the tank 1 occurs by gravity through pipes 13 exiting

with marks 123 located in the collection channel 11, arranged with a slope to the side with marks 12:., 002-0.005.

When the tank 1 is emptied with a filling exceeding the height of the transverse vertical partition 8, the waste water enters the collection channel of the drain 11 through the top of the partition.

0 When emptying the tank 1 with a filling equal to less than the height of the vertical transverse partition 8, the waste water enters the collection channel of the evacuation 11 through the culverts 9 in the cross section 8 located above the gate section. A higher emptying rate corresponds to a greater difference between the water mirror before and after the partition and a higher flow rate

0 jets into the emptying collection duct 11, with a quantity of movement mxV being transferred to the mass of water in the emptying collecting duct 11, thereby preventing precipitation in it.

5 When the water level in the tank drops to the height of the emptying sections 7, one of the gate sections 10 rises. After emptying the first section of the trays 7, the second gate section 10 rises and

0, the wastewater is supplied through pipes 4 and nozzles 5 for all trays 6 of the previous drainage section 7, due to which a regular washing cycle of the tray part of the bottom is created in the last stage of emptying the tank 1. After the completion of the empty cycle of the second section 7, washing is started the second section 7 and the rinsing of the first section 7 is turned off, the third section of the sliders 10 is opened and lowered into

0 trays 7 first gate section 10, etc. - until the completion of the emptying procedure and the subsequent washing of the tray part of the bottom on the last section 7.

When a water mirror falls in a tank

5 1, air enters into it through an air intake device 20 and pipes 19.

A longitudinal vertical deaf septum 16 in the tank 1 divides it into

0 two volumes isolated from each other. All filling and emptying processes in these two volumes can occur either sequentially or in parallel (simultaneously).

5 Thus, the proposed device - the regulating capacity - is a new technical solution, since it is unknown from the prior art, has an inventive step and is industrially applicable in the field of sewerage.

Initial data for calculations:

rsr, rmax, dmin - the average, maximum and minimum flow rates:

K is the coefficient of hourly unevenness;

Osc.h is the average hourly consumption per day.

The calculated parameters are:

1. The value of the volume of the regulatory capacity L / capacitance.

2. The capacity of the supply and outlet systems of the regulating capacity.

3. The diameters of the pipes of the supply system and nozzles, the diameters and slope of the emptying trays of the tray part of the bottom of the tank, the number of trays in one emptying section, the number of emptying sections, the dimensions of the culverts above each emptying section.

4. Elements of the air exchange system (in FIG. 3) for tank 1.

The volume of the storage capacity is determined in accordance with SNiP 2.04.03-85 pp. 6.54; 6.55 (Sewerage. Outdoor networks and structures. Design standards) or using Fig. 10.

The supply and discharge systems must ensure: the supply of wastewater to the tank with an intensity (pmax-o, sr) m3 / s and emptying of the tank with an intensity (qcp-dmin) m3 / s, where Yamax and dmin are determined according to Table 2 SNiP 2.04.03-85.

The diameter and slope of the trays of the tray part of the bottom are determined from the following conditions:

a) filling in one tray when feeding from one nozzle into the tray:, 2-0.5, while providing a self-cleaning speed at, 2;

6) the duration of gravity-free emptying of the tray in the final stage of emptying the container must be at least the time of the suspension of suspended solids in the layer, 2 with the length of the tray from the place of supply of wastewater (from the nozzle) to the place of emptying of the tray (to the gate). That is, the ratio should be satisfied:

ULot q (h / d 1) + q (h / d 0.2)

 V (, 2) where Slot is the volume of one tray, m,

q () is the gravity emptying of one tray at m3 / s;

q (, 2) - the same, at, 2, m3 / s;

V (h / d 0.2) - speed in the tray at, 2 m / s;

L is the length of the tray part of the bottom (along the tray), m

The width of the culverts in the transverse vertical partition should not be less than the diameter of the nozzles feeding pipes into the tank.

5 It is assumed that the use of sufficient capacity in the traditional structures of sewer systems will allow us to move on to the creation of a qualitatively new type of sewer systems, namely, regulated sewer systems designed to allow average flow throughput with a uniform load throughout the day. This will increase reliability and

5 the durability of sewage systems will reduce construction costs: by 10-30% for new construction and 40-98% for reconstruction and expansion of sewage systems.

0 If in the structure of capital construction costs, the share of sewerage accounts for about 8% of the total volume of capital investments, and of this, approximately 50% falls to the area in which the proposed technical solution can be implemented, then after its widespread introduction a decrease in investments in construction (while maintaining all other conditions) by 2-3% of the total volume of investments in construction in the country - only through the use of this technical solution.

Using the present technical solution to increase power

5 wastewater treatment plants in Zelenograd for 110 thousand m3 / day will approximately 40% reduce construction costs, as determined by the construction budget.
