This invention relates to a method for real-time online detection of wastewater indicators. Before detection, a low-concentration water body is injected into the detection chamber to perform micro-dose detection. By observing whether there is a nonlinear shift in the initial response behavior, it is determined whether there is residual response on the inner wall of the detection chamber. If so, a local delayed detection and pre-rinsing operation is performed to suppress interference responses caused by the chemical memory of the detection chamber. After completing the pre-response suppression, a slow-varying physical stimulus process is applied to the wastewater to be tested, stimulating the release of masked pollutants in the wastewater. The pollutant response signals are continuously tracked, and fluctuating behavior is identified. Based on the changing trend of the response curve, a stable response interval is identified as the sampling point for final detection. For cases with superimposed responses from multiple pollutants, the rise rate, fall rate, and tailing characteristics of the response profiles of each indicator are analyzed to identify the physical differences of multiple response signals and perform physical-level decoupling, improving the accuracy of identifying multiple pollutants.

The invention relates to the technical field of foramen endoscope operation positioning nails, in particular to a degradable developing positioning nail for a lumbar foramen endoscope operation. According to the technical scheme, the nail comprises a threaded nail body and a nail cap fixedly connected to the end of the threaded nail body, and further comprises a marking structure arranged at the end of the nail cap and used for recognizing a positioning point; the torsion stress groove is formed in the operation end of the nail cap, and a lock rod groove piece is formed in the torsion stress groove; the end of the rectangular rod is connected with a lock head piece connected with the lock rod groove piece in a locked mode, and a springback piece is arranged at the tail end of the transmission rod. The torsion stress groove and the lock rod groove piece are formed in the end of the nail cap, and the lock head piece can be stably connected into the lock rod groove piece under the cooperation of the springback piece; the tapered end piece and the rectangular rod can be withdrawn quickly without loosening the threaded nail body subsequently, so that the positioning stability of the threaded nail body is remarkably improved; and the threaded nail body, the tip part and the nail cap are all made of degradable materials and do not need to be taken out after an operation, so that the operation safety and the patient comfort are improved.
