[0027] In the sewage treatment process, the gas lift reflux device is one of the key equipment to ensure the treatment effect. Its normal operation is crucial to maintaining the stability of the entire sewage treatment system. However, during the operation of the existing gas lift reflux device, due to the lack of effective real-time monitoring means, it is often difficult to detect and deal with operating failures in a timely manner. This means that when the device fails or its performance deteriorates, it cannot provide continuous and accurate operating status information, and the staff may not be able to discover it in time, which affects the sewage treatment effect. In addition, due to the lack of real-time monitoring, the staff needs to conduct regular inspections and maintenance, which not only increases labor costs, but may also lead to greater maintenance costs due to the failure to detect potential problems in a timely manner.
[0028] To solve the above problems, the embodiments of the present disclosure provide a monitoring device, a gas lift reflux device and a sewage treatment system. The monitoring device, the gas lift reflux pipeline and the sewage treatment system of the embodiments of the present disclosure will be described below in conjunction with the accompanying drawings.

The locking gasket 1-6 and the fastening nut 1-7 are provided to make the connection between the isolation stud 1-5 and the junction box 2 more secure. In addition, the isolation studs 1-5, anti-loosening washers 1-6 and fastening nuts 1-7 can also be reused as terminal blocks for connecting cable assemblies.
[0037] In some optional embodiments, the electrode assembly 1 further includes a flat washer 1-3 and a locking nut 1-2, which are used to fasten the second portion 1-1b to the junction box 2 to prevent the electrode column 1-1 from vibrating under the impact of water flow, causing the electrode column 1-1 to fall off. Optionally, the locking nut 1-2, the electrode column 1-1 and the junction box 2 can be welded to prevent the electrode column 1-1 from falling off.
[0038] In some optional embodiments, the electrode assembly 1 further includes a sealing pad 1-4 for sealing the connection between the second portion 1-1b and the junction box 2 to prevent water vapor from entering and affecting the performance of the electrode assembly 1, thereby affecting the monitoring results and even causing damage to the monitoring device 10.
