Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, and in particular to a wastewater separation and recycling system. Background Technology

[0002] In industries such as chemical engineering, electroplating, and metallurgy, initial rainwater often mixes with production wastewater to form acidic or alkaline wastewater, such as acidic / alkaline wastewater and heavy metal ions. If discharged directly without effective separation, it will cause serious pollution to soil and water bodies. In current wastewater treatment, if acidic and alkaline wastewater are mixed together, they may produce chemical reactions to form substances that are difficult to treat, causing pollution or danger. At the same time, the treatment processes for the two are quite different, making it impossible to switch between them in a timely manner and undermining the stability of the original treatment process. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a sewage separation and recycling system to solve the technical problem that the prior art cannot classify and treat sewage in a timely manner.

[0004] To achieve the above and other related objectives, this utility model provides a wastewater separation and recycling system, comprising a separation well and a buffer tank connected in sequence, with a drain outlet at the bottom of the separation well. The wastewater separation and recycling system further includes:

[0006] An acid treatment tank, which is connected to the liquid separator valve;

[0007] An alkaline treatment tank, which is connected to the liquid separator valve;

[0008] A pH detection module is also installed inside the separation well. The pH detection module is located at the inlet end of the separation well and is used to detect the pH value of the sewage to be introduced into the separation well.

The liquid separation valve is used to adjust the connection between the separation well and the acid treatment tank or the alkaline treatment tank. The acid treatment tank and the alkaline treatment tank are respectively connected to the separation well through pipelines.

[0009] The advantage of adopting the above technical solution is that the pH value detection module monitors the acidity and alkalinity of the sewage in real time, and the liquid separation valve divides the sewage into acidic or alkaline treatment tanks according to the detection results, thus avoiding mixing reactions.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0034] Please see Figure 1 It should be noted that the illustrations provided in this embodiment are merely schematic representations of the basic concept of this utility model. The illustrations only show components relevant to this utility model and are not drawn according to the actual number, shape, and size of the components in implementation.

The structures, proportions, sizes, etc., shown in the accompanying drawings are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0035] Please see Figure 1 As shown, this utility model provides a wastewater separation and recycling system, including a separation well 1 and a buffer tank 2 connected in sequence. A drain outlet is provided at the bottom of the separation well 1. The wastewater separation and recycling system also includes:

[0036] Liquid separating valve 3, which is connected to the drain outlet;

[0037] Acid treatment tank 4, which is connected to the liquid separator 3;

[0038] Alkaline treatment tank 5, which is connected to the liquid separator 3;

[0039] A pH detection module is also provided inside the separation well 1. The pH detection module is located at the inlet end of the separation well 1 and is used to detect the pH value of the sewage to be introduced into the separation well 1. An indicator 101 is provided on the outside of the separation well 1 and is used to display the detection result of the pH detection module. The liquid separation valve 3 is used to adjust the connection between the separation well 1 and the acid treatment tank 4 or the alkaline treatment tank 5. The acid treatment tank 4 and the alkaline treatment tank 5 are respectively connected to the separation well 1 through pipelines.

[0040] It should also be noted that the separation well 1, as a sewage pretreatment unit, is connected to the liquid distribution valve 3 through the bottom drain outlet to achieve the initial collection and diversion of sewage; the buffer tank 2 is used to temporarily store the treated water and balance the system flow fluctuations. Sewage that meets the pH value requirements can be directly discharged into the buffer tank 2 for treatment. The liquid distribution valve 3 automatically switches the sewage flow to the acid treatment tank or the alkaline treatment tank according to the feedback from the pH value detection module to achieve the physical separation of acid and alkaline sewage.

[0041] For example, the acid treatment tank 4 includes an acid tank body 401 and an alkaline silo 402. The alkaline silo 402 is disposed on top of the acid tank body 401 and is used to add alkaline materials into the acid tank body 401.

[0042] It should also be noted that the alkaline silo is directly integrated into the top of the acidic tank, reducing the floor space required, and the material falls to the surface of the tank under gravity.

[0043] For example, the alkaline treatment tank 5 includes an alkaline tank body 501 and an acidic silo 502. The acidic silo 502 is disposed on top of the alkaline tank body 501 and is used to add acidic materials into the alkaline tank body 501.

[0044] It should also be noted that the acidic silo 502 is located at the top of the alkaline tank 501, which can reduce the floor space occupied, and the acidic material is evenly dispersed to the surface of the alkaline tank by gravity.

[0045] For example, a water pump 6 is also provided on the pipeline between the separation well 1 and the buffer pool 2.

[0046] It should also be noted that there may be a height difference or pipe bends between the separation well 1 and the buffer tank 2, which may obstruct the natural flow of fluid. The water pump provides mechanical energy to overcome the difference in gravitational potential energy and the frictional resistance of the pipes, ensuring that the sewage is stably transported from the separation well to the buffer tank. If the pH detection module detects that the sewage meets the pH requirements, the water pump 6 is activated to discharge the sewage into the buffer tank 2.

[0047] For example, the water pump 6 is a self-starting pump, and a float level gauge is also provided on the self-starting pump. The self-starting pump is used to receive the level signal of the float level gauge and start automatically.

[0048] It should also be noted that by using a float level gauge to sense the liquid level in real time, the response time is shortened, enabling the water pump to start working based on the liquid level, thus achieving zero-delay linkage.

[0049] For example, a first valve is provided at the connection between the alkaline silo 402 and the acidic pool 401.

[0050] It should also be noted that the alkaline silo is isolated from the acidic tank by the first valve, and the valve is only opened when neutralization is required to control the amount of alkaline material added.

[0051] Furthermore, the first valve can be a manual switch or an electric switch.

[0052] For example, a second valve is provided at the connection between the acidic silo 502 and the alkaline tank 501.

[0053] It should also be noted that the acidic silo is isolated from the alkaline tank by the second valve, which is only opened when neutralization is required, thus controlling the acid-base contact time within a safe range and controlling the amount of acidic material added.

[0054] Furthermore, the second valve can be a manual switch or an electric switch.

[0055] For example, the float level gauge is connected to the self-starting pump via a connecting rod.

[0056] It should also be noted that by directly transmitting the float displacement through the connecting rod, the reliance on electronic components is eliminated, the system reliability is improved, and the maintenance cost is reduced. The float rises and falls with the liquid level, causing the connecting rod to rotate or move linearly. The end of the connecting rod is connected to a water pump start switch, such as a micro switch or a mechanical lever. When the connecting rod moves to a set angle, the switch is triggered.

[0057] For example, the pipes between the separation well 1 and the acid treatment tank 4 and the alkaline treatment tank 5 are made of stainless steel.

[0058] It should also be noted that stainless steel pipes are used between the separation well and the acid-alkali treatment tank. Through their corrosion resistance, high strength and long service life, the safety, economy and environmental protection of the industrial wastewater treatment system are significantly improved.

[0059] For example, both the acid treatment tank 4 and the alkaline treatment tank 5 are equipped with acid-base detection devices, which are used to detect the pH value in the acid treatment tank 4 or the alkaline treatment tank 5.

[0060] It should also be noted that acid and alkali detection devices are installed on the acid treatment tank and the alkaline treatment tank. Through real-time monitoring, precise control and abnormal early warning, the compliance, economy and safety of the industrial wastewater treatment system are significantly improved. It can determine whether the wastewater has completed pH adjustment. If it has completed adjustment, it can be transported to the separation well 1 through the pipeline, and then enter the buffer tank 2 when the pH value meets the requirements.

[0061] In summary, the wastewater separation and recycling system of this utility model achieves the classified treatment of acidic and alkaline wastewater through real-time pH value detection and intelligent diversion. It effectively solves the safety risks, process interference, and pollution aggravation caused by mixed treatment, and has significant economic, environmental, and operational advantages.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
