Description
Technical Field
The utility model belongs to the technical field of the water treatment, concretely relates to intercept dirty regulation system including just rain pipe.
Background
The urbanization is rapidly developed, the urban land area is gradually expanded, and the urban rainwater pipe network structure is more and more complex, so that the treatment pressure of the urban rainwater treatment system is more and more serious, and the urban rainwater treatment system is also subject to huge transition.
The most commonly used contemporary split-flow water treatment system in the early days has a relatively complete storm water pipe structure and municipal sewage system, and they are completely separated, since it is not limited by land area, municipal population, and environmental and atmospheric pollution. The urban sewage directly enters a sewage treatment system through a sewage pipe network for collection and treatment; the rainwater pipe network directly receives urban rainwater and discharges the urban rainwater into a natural water body, and the urban rainwater pipe network and the natural water body are not communicated with each other and do not interfere with each other. However, as the population proliferates, the land area is limited; the continuous adoption of two pipe networks for treating sewage and rainwater cannot meet the requirements of social development; moreover, the coming of the industrial age causes a series of environmental and atmospheric pollution, so that the initial rainwater contains a large amount of pollution sources, and if the rainwater is directly discharged into a natural water body through a rainwater pipe network without being treated, the rainwater can be used by human beings without clean water. Forced to this, people are beginning to seek new rainwater and sewage treatment systems, which are mainly classified into three types: split flow, combined flow and mixed flow. The split-flow rainwater and sewage treatment system is generally constructed in a certain region of a city to form a catch basin structure, and polluted initial rainwater is accumulated and conveyed to the urban sewage treatment system for treatment, so that the rainwater is effectively prevented from being discharged into a natural water body to pollute the natural water body. Combined rainwater and sewage treatment systems are generally used for building a rainwater and sewage shared water treatment system in a certain region of a city. The mixed flow system is a brand new water treatment system constructed according to the split flow system and the combined flow system. Although the separation of initial rainwater and middle and later stage rainwater can be realized to a certain extent to above-mentioned three kinds of rainwater pipe network structures, when actually being applied to rainy season, the sewage pipe is during the sewage pipe is catched in a large amount of initial rainwater in the original sewage volume plus, carry to sewage treatment plant, cause serious water pressure for sewage treatment plant, and it can't realize the processing to the water very fast, and unnecessary water can only be discharged to natural water, and such drainage system has lost the effect that drainage system should play completely.
In order to solve the above problems, the current solution is to perform a storage adjustment process on the drainage system. However, the existing regulation and storage system generally adopts an overground or underground regulation and storage tank, but the regulation and storage tank needs to occupy a large area, the excavation depth is also large, the current land is short, land acquisition is also very difficult, in addition, the regulation and storage tank is constructed at one point in a centralized manner, and as a regulation and storage tank for non-point source pollution control, non-point source pollution loads in a large area on the ground need to be collected into the regulation and storage tank in a centralized manner through a drainage pipeline, the more difficult and higher cost are realized, the more critical is that the collection efficiency of the pollution loads is very low, because the non-point source pollution loads in a far area can enter the regulation and storage tank in the conveying process from the ground to a tail end regulation and storage tank, because of being mixed with a large amount of later-stage rainwater, the initial-stage rainwater collected in the regulation and storage tank contains a large amount of later-stage rainwater, and the average concentration of the pollution. In addition, in some areas, the reconstruction difficulty of the existing pipeline is very high, and the factors seriously influence the efficiency of water treatment and the actual effect of regulation and storage.

because the 4 th regulation district is the regulation district of rearmost end, utilizes PLC controller and level sensor, the water liquid level height in the 4 th regulation district of real-time detection, when it reaches full pipe state, closes 3 rd retaining equipment, explains can't get into more waters in the 4 th regulation district this moment. The height of the water level in the 3 rd regulation area is detected in real time, when the water level reaches the full pipe state, the 2 nd arresting device is closed, the rest is done by analogy in sequence, if the rainfall is not reduced continuously until all the arresting devices are closed, and the initial rain pipe does not have the regulation capacity at the moment.
In another aspect of this embodiment, the storage areas may not reach a full pipe state, for example, 3 lower opening weir doors along the primary rain pipe are opened to a set storage height H'; at this time, the corresponding storage spaces in the respective storage regions are V1 ", V2", V3 "and V4", and V1 "> V1 ', V2" > V2', V3 "> V3 ', V4" > V4'.
Example 3
When the rainfall is reduced or the rainfall stops, the water in the regulation and storage area is discharged downstream by adjusting the opening or closing state of one or more water blocking devices, but the total discharged water amount is kept not to exceed the treatment capacity of a sewage treatment device or a sewage treatment plant. Preferably, the water in the most downstream storage area is discharged to a sewage treatment plant or a sewage treatment plant.
For example, draining the water in the 4 th regulation zone such that the water level in the 4 th regulation zone is lowered to H4; closing the 3 rd water blocking device at the upstream to enable the water body to flow into the 4 th regulation area; discharging the water body in the 4 th regulating and storing area again to ensure that the water body liquid level in the regulating and storing area is reduced to H4; and closing the water blocking devices further upstream in sequence until the 1 st water blocking device is closed, and discharging the water in the 1 st regulating area to enable the water level height in the 4 th regulating area to be reduced to H4.
Or the following method is adopted: discharging the water body in the 4 th regulation area, closing the 3 rd water blocking device at the upstream after a time interval of 30-60min, and enabling the water body to flow into the 4 th regulation area; and closing the upstream 2 nd water blocking device after 30-60min time interval again, and according to the method, closing the 1 st water blocking device.
The embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiment. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
