Description

The invention relates to the field of sanitary engineering and can be used in the discharge and treatment of wastewater in alloy systems for general disposal.

A known drainage system, including control tanks, to which the entire rainwater flow is supplied through a large-diameter pipe with the simultaneous discharge (emptying) of a part of the flow through a small-diameter pipe (see Alekseev MI, Kurganov AM Organization of surface (rain or melted) runoff from urbanized territories: Textbook. - M.: DIA Publishing House; St. Petersburg: SPbGASU. - 2000. - 352 p., Fig. 7.6a, 7.13).

The well-known system is characterized by high capital costs, since it uses a separately constructed structure as a regulatory capacity, and does not use the free space of pipelines and wells.

The closest analogue (prototype) to the claimed invention is a megalopolis drainage system (see patent RU No. 2438984, C02F 1/00. Megalopolis drainage system / FV Karmazinov, MD Probirsky, Yu.A. Ilyin, BC Ignatchik et al. Priority of June 11, 2010), including: a sludge disposal subsystem containing at least the following successive units: dehydration, heat treatment, ash removal from flue gases, flue gas treatment, and also backup storage of dehydrated sludge connected to dehydration and thermal blocks processing, transporting ash, loading dehydrated sludge connected to a back-up storage unit for dehydrated sludge and / or to a heat treatment unit, at least one additional sludge disposal subsystem, at least one sludge treatment subsystem, containing the following successive units: wastewater treatment with sludge extraction, preparation for sludge dehydration, dehydration, storage and unloading of dehydrated sludge, transportation of dehydrated sludge, at least one landfill sludge, while the ash transporting units connect the ash removal units of the sludge disposal subsystem, additional / additional sludge disposal subsystems with the sludge landfill, the dehydrated sludge storage and discharge units of the sludge treatment subsystem / the dehydrated sludge transporting unit / units are connected to the block loading of dehydrated sludge subsystems for utilization of sludge, additional / additional subsystems for utilization of sludge and with landfill / landfills for sludge disposal, at least at least one emergency transport road that connects the sludge landfill with dehydrated sludge back-up storage units, the dehydrated sludge back-up storage unit for the sludge utilization subsystem - with the additional / additional subsystem / sludge utilization dehydrated sludge loading units, the dehydrated back-up storage unit sludge of additional / additional subsystems / subsystems of utilization of sludge - with a loading unit for dehydrated sludge of the subsystem for utilization of sludge at least two sewage basins and at least one suburb of the metropolis, with the sludge utilization subsystem, additional / additional sludge utilization subsystems and sludge treatment subsystem / subsystems located in different megalopolis sewerage pools, and / or sludge treatment subsystem / subsystems located in the suburbs / suburbs of the metropolis. The sludge utilization subsystem, the at least one additional sludge utilization subsystem are additionally equipped with sewage transport units located in front of the dewatering units, containing inlet collectors and main pumping stations connected to each other with receiving tanks, maximum and minimum water level sensors, supply pipelines, while the supply manifolds are made with the smallest possible slope and are connected to the receiving tanks from between the maximum and minimum level sensors, wastewater treatment units with sludge extraction, containing a receiving chamber in series, gratings, sand traps, primary sedimentation tanks connected to dewatering units, aeration tank, secondary settling tanks connected to dewatering units to supply excess dewatering units sludge and with an aerotank for feeding returnable activated sludge into it, by gravity centrifugal lines, while the dehydration units and the supply collector are connected by gravity centrifugal lines, between asseynovoy pump station with a supply line and a pressure line, wherein the supply conduit is connected to a supply manifold sludge recycling subsystem and the pressure line - to a supply manifold additional subsystems sludge disposal.

Possible development options of the known system when:

1. The inlet pipe is connected to the inlet collector of the additional sludge utilization subsystem, and the pressure line is connected to the inlet collector of the sludge utilization subsystem (development option No. 1).

2. The sludge utilization subsystem, at least one additional sludge utilization subsystem is additionally equipped with internal pumping stations with pressure pipelines, while the dewatering units and internal pumping stations are connected by gravity centrifugal lines, and the pressure pipelines of the internal pumping stations are connected to receiving chambers.

3. The sludge utilization subsystem, at least one additional sludge utilization subsystem is additionally equipped with at least one gravity collector of the internal drainage system, while at least one gravity collector of the internal drainage system is connected to the internal pump station.

4. Sludge utilization subsystem, at least one additional sludge utilization subsystem is additionally equipped with district sewage pumping stations with pressure collectors, while pressure collectors are connected to the supply collectors.

5. Pressure manifolds are connected to receiving chambers.

7. Pressure manifolds are connected to internal pumping stations.

8. Pressure manifolds are connected to gravity lines of the centrate.

9. Pressure collectors are connected to at least one gravity collector of the internal drainage system.

The disadvantages of this system are the low reliability indicators of the discharge of the drain outside the village, because High probability of flooding the territory of the metropolis, because:

- during periods of heavy or over-calculated rains, when the capacity of the supplying collectors is less than the flow rate of the incoming flow, filling of their free volume and the release of wastewater to the surface within the metropolis can occur;

- in case of clogging or accident at the sections of the supplying collectors, when drains from subscribers located above these sections, fully or partially through the wells, rise to the surface.

The objective of the present invention is to increase the reliability of the system.

The problem is solved in that the known system, including a wastewater transport unit containing at least a collector, in accordance with the present invention is further provided with:

- drainage networks connected to the collector;

- an overflow pipe connected to drainage networks and an emergency overflow device containing at least an eye attached to the upper part of the body, a rotary flap rigidly connected to the headscarf, which is rotatably connected to the eye, a variable-weight barrier load connected to a kerchief or flap, providing closing of the flap at a water level below the minimum value of the earth's surface above the collector and drainage networks.

Compared with the prototype of the proposed system has the following distinctive features.

1. Additional supply of the system with drainage networks connected to the collector (Known).

2. Additional supply of the system with an overflow pipe (known).

3. The connection of the overflow pipeline with drainage networks (known).

4. Connection of an overflow pipeline with an emergency overflow device (known).

5. Implementation of an emergency overflow device comprising at least a housing attached to an eyelet to the upper part of the housing, a rotary flap rigidly connected to the scarf, which is connected to the eye with the possibility of rotation, a variable-weight barrier load (not known).

6. Attachment of a variable-mass barrier load to a kerchief or flap, which provides closing of the flap when the water level is below the minimum value of the earth's surface above the supply collector and drainage networks (not known).

According to the information available to the authors, the distinguishing features No. 1-4 in the technical literature are known, and the rest are not. However, their combined use in the inventive system will allow to obtain a positive effect and super-effect.

The positive effect is that environmental safety indicators increase, as the probability of flooding the territory of the metropolis is reduced, because during periods of heavy or over-calculated rains, when the collector and network capacity is less than the flow rate of the incoming flow, as well as during clogging or accident at the collector and network sections, their free volume will only be filled until the water level will be below the minimum value of the surface of the earth above the collector and the drainage network, i.e. before water comes to the surface. The flap will be closed during this period. And when the water level rises above the minimum value of the surface of the earth above the collector and the drainage network, i.e. the water rises to the surface of the earth, the flap opens and the wastewater is organized into places less hazardous to the environment or into the regulating tank. As a result, wastewater will not reach the surface of the metropolis (due to the presence of hallmarks 1-6).

The super-effect is that the required level of reliability indicators can be achieved while improving environmental safety indicators. This is achieved by:

- the use of additional free regulatory volume of water disposal networks (due to the presence of hallmark 1);

- the use of additional free regulatory volume of the collector (due to the presence of distinctive features No. 1-6);

- regulation of the level of opening the flap of the emergency overflow device (due to the presence of distinctive features No. 5-6).

As a result, wastewater discharges through an overflow pipeline will be minimized, because the flap will only open in exceptional cases when the effluent threatens to enter the territory of the metropolis.

Thus, the claimed water disposal system of the metropolis meets the criterion of "inventive step".

The system proposed by the authors is structurally different from the prototype.

In FIG. 1 shows an embodiment of the general technological scheme of the proposed controlled drainage system, FIG. 2 - profile AB shown in FIG. 1 of the system, in FIG. 3 is an embodiment of an emergency overflow device, in FIG. 4 is a view A of FIG. 3 devices.

The general technological scheme of the proposed system includes (see. Fig. 1, 2):

- a wastewater transport unit 1 comprising a collector 2 and a sewage network 3 connected to a collector 2;

- overflow pipe 4 connected to the networks 3 drainage and emergency overflow device 5.

The emergency overflow device 5 (see. Fig. 3, 4) contains:

- housing 6 connected to the overflow pipe 4;

- an eye 7 attached to the upper part of the housing 6;

- a rotary flap 8, rigidly connected to the scarf 9, which is connected with the eye 7 with the possibility of rotation;

- a variable-weight barrier load 10 connected to the kerchief 9 or flap 8, providing closure of the flap 8 at a water level below the minimum value of the earth's surface above the collector 2 and drainage networks 3. In FIG. 3, 4, an embodiment is shown when a variable-weight barrier load 10 is attached to the scarf 9.

The present invention does not exclude the presence of additional elements, for example, a saddle 11, which is integral with the body 6, and a sealing element 12 connected to the rotary flap 8. Together they ensure the tightness of the emergency overflow device 5 when the flap 8 is closed.

The optimal drainage system works as follows.

Wastewater from the sewage network 3 flows into the collector 2, and from it is discharged outside the settlement (not shown in Figs. 1 and 2). In trouble-free periods of work and in dry weather, when the influx of wastewater entering the drainage network 3 and collector 2 is less than their capacity, the drainage system operates in the calculated mode. At the same time, a variable-weight barrier load 10 connected to the kerchief 9 or flap 8 ensures closure of the flap 8. As a result, all wastewater is discharged outside the settlement without wastewater through an overflow pipe 4.

In periods of heavy or over-calculated rains, when the throughput of collector 2 and network 3 will be less than the flow rate of the incoming flow, as well as in the event of clogging or accident at the sections of collector 2 to the point of intersection with network 3, filling of their free volume will begin with a rise in water level. With its further increase, while the water level is below the minimum value of the earth's surface above the collector 2 and the drainage network 3, the flap will be closed. And when the water level rises above the minimum value of the surface of the earth above the collector 2 and the drainage network 3, i.e. It will be above the surface of the earth, the flap will open, and the wastewater will be organized in places that are less hazardous to the environment or in the regulating tank. As a result, there will be no exit to the surface of wastewater within the metropolis. Thus, water discharge will be provided at the lowest possible volume of wastewater discharge through an overflow pipe 4.

The present invention allows various options for determining the mass of the barrier cargo 10, for example:

- an experimental option, when the collector 2 with the network 3 is filled during over-calculated rain or by creating artificial clogging to the maximum possible level when water from them does not spill onto the surface. During this period, the minimum weight of the load 10 is selected, ensuring the holding of the flap 8 in the closed position;

- the experimental version differs from the experimental one in that the required mass of the load 10 is determined on the hydraulic model.

Thus, the proposed optimal drainage system is characterized by industrial applicability.
