The method is not only suitable for emergency dispatching of sewage of the first-stage catch basin, if sewage in the second-stage catch basin cannot be processed in time due to the reasons, the sewage in the second-stage catch basin is dispatched to the third-stage catch basin through the submersible sewage pump B1, the submersible sewage pump B2, the submersible sewage pump B3, the submersible sewage pump B4, the adjusting water channel B1, the adjusting water channel B2, the adjusting water channel B3 and the adjusting water channel B4, and similarly, when the sewage cannot be processed in time due to the reasons in the next-stage catch basin, the sewage is dispatched to the next-stage catch basin in sequence, until the sewage in a certain catch basin is processed normally, the electric valve actuator 16 is controlled by the control cabinet 5 to connect the submersible sewage pump 11 and a sewage pipe in the well, and the sewage pipe conveys the sewage to a sewage processing plant through a sewage main channel, so that the sewage can be processed normally.
As shown in fig. 3: FIG. 3 is a diagram of a cross-regional dispatch system for a rainstorm season of the present invention:
when the rainfall of the terrain area where the intercepting well node is located reaches a preset threshold value, the intercepting well node in the terrain area conveys rainwater to a higher intercepting well node in an adjacent terrain area, and the higher intercepting well node in the terrain area discharges the rainwater to a river channel.
The cross-regional scheduling system in the rainstorm season is generally suitable for sunny days and early rainfall stages, and comprises the following specific steps: the sewage that the rain sewage confluence pipe conveys to the intercepting well is conveyed to a sewage pipe through a submersible sewage pump 11 in the well, the sewage pipe is communicated with a sewage main, the sewage main is connected with a sewage treatment plant, and finally the sewage in the intercepting well is conveyed to the sewage treatment plant for treatment. In the middle and later periods of rainfall and in the period of rainstorm, sewage in the rainwater and sewage converging pipe is diluted and conveyed by rainwater. When the rain gauge 3 beside the intercepting well detects that rainstorm comes, the cross-regional scheduling system in the rainstorm season is implemented by combining the forecast data of the weather center. The specific implementation is as follows: in some areas with low terrain and easy waterlogging, when rainwater conveyed into the primary intercepting well through the rainwater and sewage collecting pipes 1 and 2 cannot be discharged to a river channel in time, the ultrasonic liquid level meter 17 arranged on the side wall of the intercepting well mouth detects that the water level in the well is too high, the submersible sewage pump A1 and the submersible sewage pump A3 in the primary intercepting well are started through the cloud platform, meanwhile, the control cabinet 5 controls the electric valve actuator 16 arranged above the three-way valve 15, the electric valve actuator 16 enables the three-way valve 15 to respectively communicate the pump A1 and the submersible sewage pump A3 in the primary intercepting well with the adjusting water channel A1 and the adjusting water channel A3, and excessive rainwater in the intercepting well 1 is dispatched to the secondary intercepting well.

Similarly, when the ultrasonic liquid level meter 17 in the second-stage catch basin detects that the water level of rainwater is too high, the early warning information is uploaded to a cloud platform through the control cabinet 5, the cloud platform opens the electro-hydraulic flat gate 12 in the second-stage catch basin through the control cabinet 5 to discharge a part of rainwater in the second-stage catch basin to a river channel, simultaneously opens the submersible sewage pump B1, the submersible sewage pump B2, the submersible sewage pump B3 and the submersible sewage pump B4, then enables the submersible sewage pump B1, the submersible sewage pump B2, the submersible sewage pump B3 and the submersible sewage pump B4 to be respectively communicated with the adjusting water channel B1, the adjusting water channel B2, the adjusting water channel B3 and the adjusting water channel B4 through the electric valve actuator 16, the rainwater in the second-stage catch basin is dispatched to the catch basin with a higher potential, the cloud platform opens the electro-hydraulic flat gate in the third-stage catch basin through the control cabinet 5 to discharge the rainwater in the third-stage catch basin through the river channel C63. Similarly, if the river channel is communicated with the second-stage intercepting well, the rainwater in the area with low terrain and easy waterlogging is dispatched in the intercepting well with high terrain of the next stage in sequence through the intercepting well in the cross-regional dispatching system in the rainstorm season, and finally the excessive rainwater is discharged through the river channel connected with the intercepting well, and the water in the river channel is finally collected to the Taihu lake or the Yangtze river, so that the problems of urban waterlogging and the like are solved.
Compared with the prior art, the invention has the advantages that the catch basins in different areas are networked, and the rainwater in the low-lying areas in the middle and later periods of rainstorm season rainfall is dispatched to the areas with high terrain in a transregional mode and is discharged through the river channel. The invention can carry out cross-regional emergency dispatching treatment on sewage in the intercepting well. The invention can realize the combined treatment of sewage in different areas and relieve the condition of high sewage treatment pressure in certain areas.
Finally, each parameter of the intercepting well in the whole area is monitored in real time through the cloud platform, measures are taken in advance according to weather forecast conditions, and two submersible sewage pumps are started to drain sewage in the intercepting well for rainwater regulation in emergency.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
