Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an adjustable water volume, drop-free aeration pipe channel. Background Technology

[0002] In wastewater treatment processes, structures such as anaerobic and anoxic tanks have extremely strict requirements for dissolved oxygen concentration, typically needing to be controlled below 0.2 mg / L. This is because the microorganisms in these tanks require an anaerobic or oxygen-free environment to carry out metabolic activities, achieving goals such as the degradation of organic matter and nitrogen and phosphorus removal. However, traditional pipe and channel systems often use weirs and other devices to regulate water flow. These devices cause water to cascade and come into contact with air during operation, resulting in a cascading aeration phenomenon. This phenomenon increases the dissolved oxygen concentration, thereby disrupting the anaerobic environment within the tank, affecting the normal metabolism of microorganisms, and reducing wastewater treatment efficiency.

[0003] Therefore, in order to solve this problem, it is necessary to design a new type of pipe and channel device that can achieve drop-free aeration, which is of great significance for improving the operating efficiency and treatment effect of sewage treatment system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable water volume non-drop aeration pipe channel that can flexibly adjust the height of the baffle according to the sewage volume, so that the sewage fills the first water distribution pipe as much as possible, avoiding or reducing the occurrence of drop aeration, and is suitable for water treatment scenarios that need to maintain an anaerobic environment.

[0005] The technical solution of this utility model is as follows:

[0006] The adjustable water volume non-drop aeration pipe channel includes the pipe channel body, at least two water distribution pipes are vertically spaced at the outlet end of the pipe channel, and a height-adjustable baffle is installed between two adjacent water distribution pipes at the outlet end of the pipe channel body. The pipe channel body is equipped with a level gauge.

[0007] Preferably, the baffle is a slide gate valve.

[0008] Preferably, three water distribution pipes are provided.

[0009] Preferably, the water distribution pipe is welded or flanged to the outlet end of the pipe body.

[0010] Preferably, the height of the baffle increases sequentially along the water flow direction.

[0011] Preferably, a photoelectric sensor is provided on one side of the baffle.

[0012] Preferably, a plurality of overflow pipes are provided on the side wall of the pipeline body.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This utility model's adjustable water volume, drop-free aeration pipe channel can flexibly adjust the height of the baffle according to the sewage volume, so that the sewage fills the first distribution pipe as much as possible. Since the sewage does not come into contact with air or has little contact with air when it is transported in the distribution pipe, the occurrence of drop-aeration is avoided or reduced. It is suitable for water treatment scenarios that require maintaining an anaerobic environment, and improves the operating efficiency and treatment effect of the sewage treatment system.

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment provides an adjustable water volume, drop-free aeration pipe channel, including a pipe channel body 1. Three branch pipes 2 are vertically welded to the outlet end of the pipe channel. An adjustable-height baffle is installed between two adjacent branch pipes 2 at the outlet end of the pipe channel body 1. A level gauge is installed on the pipe channel body 1. In this embodiment, the adjustable-height baffle can be a slide valve 3, and the valve plate height of the two slide valves 3 increases sequentially along the water flow direction.

[0023] Working principle:

[0024] This pipework device is mainly used to transport sewage to a pool with low dissolved oxygen. In use, the pipework of this embodiment is installed in a suitable location, allowing sewage to flow smoothly into the pipework body 1. Then, according to actual needs, the height of the valve plate of the first gate valve 3 is adjusted so that the sewage is intercepted and flows into the first distribution pipe 2. This allows the sewage to fill the first distribution pipe 2 as much as possible during its flow and be directly transported to the target pool. Because the sewage does not come into contact with air during its transport in the distribution pipe 2, there is no cascading aeration phenomenon, thus avoiding the problems associated with traditional cascading aeration.

[0025] In this embodiment, precise control of sewage volume is achieved by setting up the water distribution pipe 2 and the height-adjustable baffle. In practical applications, the height of the gate valve 3 can be flexibly adjusted according to different sewage volumes, improving the applicability and flexibility of the device. For example, at different treatment stages in a sewage treatment plant, the height of the first gate valve 3 can be adjusted according to the influent water quality and effluent requirements to ensure that sewage first enters the first water distribution pipe 2; when the level gauge detects a large amount of sewage in the pipe body 1, the height of the first gate valve 3 can be appropriately lowered so that the excess sewage after filling the first water distribution pipe 2 enters the second water distribution pipe 2, thus adapting to the treatment needs of different sewage volumes.

[0026] Example 2

[0027] Based on Example 1, a photoelectric sensor is installed at a suitable height on one side of the slide gate valve 3. When the valve plate of the slide gate valve 3 rises to the height of the photoelectric sensor, the photoelectric sensor detects the valve plate and feeds the signal back to the control system. The control system can then control the valve plate of the slide gate valve 3 to stop rising, thus limiting the valve plate position.

[0028] Example 3

[0029] Based on Example 1, several overflow pipes are provided on the side wall of the pipe body 1. If the sewage level in the pipe body 1 is too high, some sewage can be discharged through the overflow pipes.
