Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a diverter well for mixed-flow and separate drainage of rainwater and wastewater. Background Technology

[0002] In response to the global trend of carbon sequestration, national and local authorities are increasingly tightening their control over water resources. Currently, for most data center parks, regardless of whether they use water cooling, evaporative cooling, or liquid cooling, the discharge of cooling wastewater is gradually becoming a limiting factor. The tightening of wastewater discharge policies not only targets newly built data centers but also those already in operation.

[0003] For existing data centers already in operation, there were no clear regulations or provisions during the early planning and design stages. In particular, when the 2019 building water supply and drainage design standards were not implemented, the circulating cooling wastewater was usually discharged into the rainwater pipeline system according to the policy guidance at that time. This was because the municipal pipe network was not perfect during the construction and operation period, and because the scale of sewage treatment plants in some towns was limited and could not accommodate the daily peak drainage of data centers. As a result, equipment cooling wastewater and rainwater were discharged together. The downstream of the rainwater outlet is often a river, lake or sea. The discharge of high-concentration saline water into these areas can easily cause water imbalance. At the same time, after the drainage policy was tightened, it was required that production-related wastewater must meet the standards before being discharged into the sewage system. The mixed flow system faces the problem of not being able to separate the drainage system into wastewater and rainwater. It is almost impossible to carry out a small-scale municipal buried pipeline project to modify the system when the business is in operation.

[0004] Existing mixed-flow drainage systems are all integrated designs, making it impossible to plan according to actual drainage conditions. This reduces the workload of urban sewage treatment plants, plays a role in peak shaving of wastewater discharge, and solves the problem of sewage treatment plants being denied discharge approval due to their size. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a diverter well for mixed-flow and separate drainage of rainwater and wastewater, which solves the problem of diverting sewage without dismantling or modifying the work.

The three sets of signal receivers are installed at different heights according to the set values. Sensor B is matched with the signal receivers, and the control cabinet body is electrically connected to the signal receivers.

[0008] This is used to ensure that when sensor B rises with the liquid level and reaches a designated position, it sends a signal to the signal receiver.

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] According to the embodiments of this utility model, combined with Figures 1 to 5 The diagram shows a diversion well for a mixed-flow, separate drainage system for rainwater and wastewater, comprising: a drainage component 1, a diversion component 2 disposed within the drainage component 1, a diversion well 11 including a rainwater pipe 12 installed at one end of the diversion well 11 and a wastewater pipe 13 installed at the other end of the diversion well 11; and a control cabinet body 21 mounted on the ground, electrically connected to sensors A22 and B23. Sensor A22 is specifically a chloride online monitor (model CT-7600), and sensor B23 is specifically a liquid level sensor (model NT). (63-KN-MS-M12 / 970) Sensors A22 and B23 are both installed inside the diversion well 11. Lifting hinges A24 and B26 are installed inside the diversion well 11. A valve A25 is installed at one end of the lifting hinge A24 and is matched with the rainwater pipe 12. A valve B27 is installed at one end of the lifting hinge B26 and is matched with the sewage pipe 13.

[0028] When no rainwater enters the diversion well 11 for the confluence operation, sensor A22 performs monitoring. When sensor A22 detects that the parameter exceeds the set value, sensor A22 sends a signal to the control cabinet body 21. Then, the control cabinet body 21 sends a command to the hoisting hinge A24 and hoisting hinge B26, ultimately achieving the closed state of valves A25 and B27. The submersible sewage pump 14 then operates to transport the wastewater in the sewage tank 112 to the designated wastewater treatment device.

[0029] When no rainwater enters the diversion well 11 for collection operations, sensor A22 performs monitoring operations. When sensor A22 detects that the parameter has not reached the set value, sensor A22 sends a signal to the control cabinet body 21. Then, the control cabinet body 21 sends a command to the hoisting hinge A24, which opens valve A25. At this time, valve B27 is still in the closed state, and then the wastewater enters the municipal sewage system from the rainwater pipe 12.

[0030] When rainwater enters the diversion well 11 for collection operations, but the amount of rainwater is small, the signal sent by sensor B23 cannot be received by the signal receiver 111 installed at the bottom of the diversion well 11. Then, sensor B23 and signal receiver 111 send the signal to the control cabinet body 21. The control cabinet body 21 then determines according to the written program that the liquid level in the diversion well 11 is at a safe level, and then sends a signal to the hoisting hinges A24 and B26. The hoisting hinge A24 controls valve A25 to close, and the hoisting hinge B26 controls valve B27 to open, so that the wastewater and the previously collected rainwater are discharged from the sewage pipe 13 into the municipal sewage system.

[0031] When sensor B23 floats upward with the liquid level in diversion well 11 and exceeds the signal receiver 111 located at the bottom of diversion well 11, a signal is first sent to the control cabinet body 21 through sensor B23 and signal receiver 111. Then, the control cabinet body 21 sends corresponding instructions according to the written program. At this time, the valve A25 is opened by thirty degrees through the lifting hinge A24, and the valve B27 is fully opened through the lifting hinge B26, so that rainwater and wastewater enter the municipal sewage system and overflow through the municipal rainwater pipe 12.

[0032] When sensor B23 floats upward with the liquid level in diversion well 11 and is higher than the signal receiver 111 located at the top of diversion well 11 and the signal receiver 111 installed near the wellhead of diversion well 11, it indicates that the rainfall is heavy and the park is flooded. The hoisting hinge A24 receives a signal from the control cabinet body 21 to control valve A25 to be fully open, and the hoisting hinge B26 receives a signal from the control cabinet body 21 to control valve B27 to be closed. Due to the heavy rainfall, the wastewater in diversion well 11 is diluted and then discharged through the municipal rainwater pipe 12.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
