When introducing the water storage and flushing control method for the incoming sewage main pipe, firstly, the connection relationship between the incoming sewage pipeline and the sewage plant water collecting well is explained:

referring to fig. 1, fig. 1 is a schematic structural view illustrating connection between a sump well and a sewage pipeline of a sewage plant according to an embodiment of the present disclosure. The sewage pipe 200 is respectively communicated with the sewage plant sump 300 and the sedimentation tank 400, and the sedimentation tank 400 is also communicated with the sewage plant sump 300 through a pipe. The retaining gate 110 is provided on the main pipe of the sewage pipe 200 near the sump 300 of the sewage plant, and the retaining gate 110 may be provided on only one main pipe or may be provided on a plurality of main pipes. And the rest part of the sewage pipeline can be provided with a plurality of water quality detecting meters 120, flow meters 130, liquid level meters 140 and rain gauges 150.

Referring to fig. 2, fig. 2 is a flowchart of a method for controlling impoundment flushing of a main pipe of incoming sewage according to an embodiment of the present application. The embodiment of the application discloses a control method for water storage and flushing of a main sewage pipe entering a plant, which mainly comprises the following steps:

s100, acquiring the residual space amount in the sewage pipeline;

specifically, in the embodiment of the application, the liquid level meter can monitor the liquid level of the sewage pipeline in real time, and the height of the water level in the sewage pipeline can be determined through the liquid level.

In summary, the server may obtain the second water level height in the sewage conduit by using a liquid level meter disposed in the sewage conduit;

after obtaining the water level height, the server may calculate the volume occupied by water in the sewage conduit according to the second water level height.

It is emphasized that the length, inner diameter, outer diameter, etc. of the sewage pipe are known, and when the water level is known, the volume occupied by water in the sewage pipe can be calculated from the inner diameter, length, etc. of the sewage pipe.

S200, acquiring a first water level height of a water collecting well of a sewage plant;

in the embodiment of the application, equipment for measuring the water level height, such as a laser sensor, can be arranged in the water collecting well of the sewage plant; or scales can be arranged in the water collecting well of the sewage plant, and the water level height can be known through the scales.

S300, when the first water level is higher than a first preset threshold value and the residual space amount is higher than a second preset threshold value, sending a control instruction, and closing a blocking and storing gate of the sewage pipeline to store water in the residual space amount.

Further, the embodiment of the present application further includes: when the residual space amount is smaller than the second preset threshold value, sending a control instruction, and opening a storage gate of the sewage pipeline;

or when the water content is less than a first preset threshold value, sending a control instruction to open the impounding gate of the sewage pipeline.

The first preset threshold and the second preset threshold may be set according to the actual situation.

This application, through the control with sewer line and the control of sewage plant sump pit combine together. In rainy seasons, the amount of water in the sump of a sewage plant is large, and the pipes usually have a certain residual space. By the method, the treatment capacity of the water collecting well of the sewage plant can be matched with the water yield of the sewage pipeline, the water storage capacity of the water collecting well of the sewage plant is large, a large residual space is reserved in the sewage pipeline, and when the retaining gate is opened, part of water of the water collecting well of the sewage plant flows into the sewage pipeline to be stored, so that the total treatment capacity of the sewage plant is increased.

Furthermore, the control method of the embodiment of the application can also be used for flushing the sewage main pipe.

For example:

or when the residual treatment capacity of the sewage plant is greater than the storage water quantity of the main sewage pipe, the retaining gate is opened, so that the sewage enters the sedimentation tank or the water collecting well of the sewage plant of the sewage treatment plant to flush the main sewage pipe, and the sewage enters the sedimentation tank preferentially.

In dry seasons, the sewage collecting well of the sewage plant can store over-standard sewage, and the relative pollution degree of water in the sewage pipe rows meets the bottom, so that the sewage in the sewage collecting well of the sewage plant is diluted. When water is drained, the retaining gate can be opened in a fractional manner, so that the impact of the sewage exceeding the standard on the sludge in the sewage pipeline is avoided or reduced, and the sludge loss is reduced.

It should be noted that the sludge is usually concentrated in the main conduit close to the sump of the sewage plant, and the sludge can be recycled.

In addition, the height of the second water level in the sewage pipeline can be controlled by opening and closing the retaining gate, namely, sewage can enter a sewage treatment plant when the sewage pipe is used for storing water.

The impoundment gate adjusts the opening and closing strategy in real time according to the running state of the water plant, the water incoming condition, the water storage condition and the monitoring data, and the overall efficiency is exerted to the maximum extent on the premise of ensuring no overflow. The aims of reducing CSO (combined overflow) and adjusting the inflow of a sump of a sewage plant are fulfilled by effectively utilizing the online storage space of a sewage pipeline in front of the plant.

Through calculation, the integrated application of the system and the method in the water storage and flushing control unit of the main pipe of the incoming plant can save the pipeline dredging cost by 8000 yuan/km & a, wherein a represents the year. The unit is commonly used in the environmental protection industry and is not explained too much. The application utilizes the online water storage space to intercept the sewage exceeding the standard, dilutes water quality, controls the water inlet amount of a factory, and reduces sludge loss. The rainwater is cut off and stored in the closed flowing water in rainy season, the pressure at the tail end of the main pipe is reduced, the rainwater overflowing in rainy season is reduced, the cut-off and stored sewage is discharged into a water plant after raining, the CSO pollution is controlled, and the treatment efficiency is improved.

Where km · a is a unit commonly used for environmental reporting and is not explained here too much.

The integrated operation of factory, network and river (lake) is the development trend of maintenance and management of drainage systems of various cities in the future. The method can solve the problems of dynamic property, multiple targets and uncertainty of the drainage system, and the maximum play of the pipe network regulation and storage capacity and the tail end sewage treatment capacity is always the pursuit direction of the town drainage system. The blocking and storing gate is arranged on the existing trunk pipe, so that the linkage joint debugging node can be quickly constructed, and has low cost, elasticity, reliability and sustainability.

The applicant also found that the sewer pipe may be damaged to some extent after long-term use. It is therefore important if the condition of each pipe can be detected so that the life of the sewer pipe can be known in time.
