Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-6, the present invention provides a technical solution of a method for controlling an intercepting well group in a drainage basin of an urban sewer network:
the combined sewage mainly comprises: runoff rainwater, domestic sewage, industrial and enterprise wastewater are discharged after reaching standards and brown water in a toilet, and in sunny days, the domestic sewage, the industrial and enterprise wastewater are discharged after reaching standards and the brown water in the toilet are mainly in the pipe and are required to enter a sewage plant 5 for treatment; in the initial rain state, as the initial rain is still serious as a pollutant, the initial rain still needs to enter the sewage plant 5 for treatment; in a continuous rainfall state, rainwater pollutants are reduced, the specific gravity of the pollutants is high and the pollutants are often positioned at the middle and lower layers of the confluence pipe 1, so that the opening degree of a sewage interception gate 12 in the intercepting well needs to be adjusted, an overflow gate 11 is opened, rainwater is discharged into a river 6 through an overflow pipe 3, and the load of a sewage plant 5 is reduced; when the water level of the river 6 is higher than the drainage of the intercepting well, the overflow sluice 11 needs to be closed to prevent the water of the river 6 from entering the confluence pipe 1, and other drainage measures need to be started.
As shown in fig. 1, normally, sewage in the confluence pipe 1 is intercepted by an intercepting well 2, and is merged into a sewage pipe 4 to flow downstream, and reaches and enters a sewage plant 5 through a lifting pump station to be treated.
As shown in fig. 2, the sewage is designed to flow from the intercepting well 1 at the upstream to the intercepting well N and then to the sewage plant 5, so that the elevation of each intercepting well is different, and the sewage flowing backwards may be arranged in a reverse order. Namely, when intercepting, the overflow gate 11 is closed upwards from the intercepting well N, and the sewage interception gate 12 is opened until the intercepting well 1; in flood discharge, the overflow gate 11 is opened from the intercepting well 1 to the intercepting well N; when the backflow is prevented, the overflow gate 11 is closed upwards from the intercepting well N, and the sewage interception gate 12 is adjusted until the intercepting well 1.
As shown in fig. 3, the intercepting well is a collection of units including a confluence pipe 1, an overflow pipe 3, a sewer 4, and an overflow gate 11, a sewage interception gate 12 and related control equipment. In the figure, D is the actually measured water level of the ultrasonic liquid level meter, A is the elevation of the bottom of the confluence pipe 1, and B is the elevation of the top of the confluence pipe 1. Normally, the overflow gate 11 is closed, the sewage interception gate 12 is opened, and sewage enters the sewage pipe 4 and flows to the sewage plant 5 for treatment.
As shown in fig. 4, i.e., equipment installed in a control box of the intercepting well. The controller PLC communicates with the cloud platform through a DTU4G module, and reads the rainfall of the region, the basin water level and the set value of control; and then the overflow gate 11 and the sewage interception gate 12 are controlled through communication.
As shown in fig. 5, with dual power supplies, the controller PLC may control the contactor to control the overflow gate 11 JV 1 and the blowdown gate 12 JV 2. Wherein the UPS supplies power for the controller PLC.
Example (b): adopting a mode of N intercepting wells in a cloud platform control area, uploading the rainfall of the area and the river level of a drainage basin to a cloud platform through 4G communication, then communicating the cloud platform to a controller of each intercepting well through 4G, performing control calculation through the controller, gradually opening an intercepting gate from a downstream intercepting well N under the conditions of no rain and no opening of the overflow gate by calculating the rainfall and the river level of the drainage basin, closing the overflow gate to ensure that all sewage enters a sewage plant for treatment, judging the initial rain state by calculating the rainfall and the river level of the drainage basin under the condition of rain, wherein the actual measured water level is less than the top water level in a confluence pipe, the overflow gate is completely closed, the opening degree of the intercepting gate is controlled by the given value of the cloud platform, intercepting the sewage, controlling the flow of the sewage, ensuring that all the sewage enters the sewage plant for treatment, and calculating the rainfall and the river level of the drainage basin, under the condition that rain exists or the overflow gate is opened, the opening degree of the sewage interception gate is adjusted step by step from the downstream intercepting well N, the overflow gate is opened, rainwater is ensured to be timely discharged into a river, the excessive load of a sewage plant is prevented from being caused, under the condition that rain exists or the overflow gate is opened, the river water level of a river basin is calculated to be compared with the elevation of the intercepting well, when the river water level of the river basin is higher than the elevation of the intercepting well, the overflow gate is closed step by step from the downstream intercepting well N, the backflow of river water is prevented, the opening degree of the sewage interception gate is adjusted at the same time, the cloud platform is uploaded to give an alarm, and other measures are arranged to drain the waterlogging.
