Description

Technical Field

[0001] The present invention relates to the technical field of source tracing monitoring, and in particular to a source tracing monitoring device and method for excessive sewage. Background Art

[0002] Source tracing monitoring, as the name implies, means monitoring by tracing back to the source. In the field of sewage treatment, source tracing monitoring methods are often used to study and trace the root causes of sewage generation, and to solve the problem of sewage exceeding the standard from the root.

[0003] The invention patent with application number: CN202011150511.3 and publication number: CN114019120A (hereinafter referred to as "prior art 1") discloses a monitoring system, device and method for monitoring the source of excessive urban sewage. Prior art 1 places the device body for detecting sewage into a delivery pipe, and through the flow of sewage, the device body is flushed into the transmission component, and the device body is recovered through the transmission component.

[0004] However, in actual use, the solution in prior art 1 is too idealistic. First, the depth of sewage in the sewer is not fixed. When the depth of sewage is close to the delivery pipe or even overflows into the delivery pipe, the device body will remain in the delivery pipe and cannot be recovered, and sewage monitoring cannot be performed. In addition, due to the gaps on both sides of the transmission component, the device body may not be recovered. The protective net blocking the device body will also make it impossible to recover the device body. Summary of the invention

[0005] The present invention provides a source tracing monitoring device and method for excessive sewage, aiming to solve the problem that the recovery of sewage monitoring devices in the prior art is unstable, which leads to poor source tracing monitoring effect of sewage.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A source tracing monitoring device for excessive sewage, comprising a sewage discharge pipe and a sewer pipe arranged below the ground, a manhole cover being arranged at one end of the sewer pipe close to the ground, and a sewage monitoring device;

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention mainly includes a sewage discharge pipe and a sewer pipe arranged below the ground, a manhole cover is arranged at one end of the sewer pipe close to the ground, and also includes a sewage monitoring device; in actual use, the staff removes the manhole cover above the sewer pipe, and then places the outer shell above the sewer pipe, and makes the position of the outlet correspond to the end position of the sewer pipe, and then starts the motor to rotate forward, and the motor rotates to make the reel release the steel rope, and the test tube passes through the outlet and enters the sewer pipe; when the test tube is lowered to a position close to the liquid surface, the staff controls the extension of the telescopic component, and after the extension of the telescopic component, the pressure plate is pushed to slide inside the protective cover, and the pressure plate compresses the half-shaft dust cover, and then drives the telescopic component to contract, at this time, due to the pressure difference generated inside the test tube, the sewage is sucked into the test tube. Then the motor is driven to reverse again, the steel rope is reeled up by the reel, and the test tube rises to the position before being lowered. The staff removes the test tube through the operation port and replaces it with a new one, so that the test tube can absorb liquid multiple times, collect sewage several times, and replace other sewer pipes to collect sewage in the same way. Finally, the absorbed sewage is analyzed to analyze whether the sewage exceeds the standard and the components in the sewage to achieve traceability monitoring. The advantage of this setting is that the test tube can be recycled in time, and the monitoring of sewage exceeding the standard will not be affected by the height of the sewage level, and the stability is better.
