Sewage treatment plant aeration equipment health condition monitoring method based on grating temperature measurement

Abstract

The invention discloses a sewage treatment plant aeration equipment health condition monitoring method based on grating temperature measurement, belongs to the technical field of sewage treatment, and aims at detecting an aeration disc by using a fiber grating detector and solving the problem that the manual detection of the health condition of sewage treatment plant aeration equipment needs to bear great maintenance cost. The method comprises: obtaining an aeration disc installation drawing, determining the number of fiber grating detectors according to the aeration disc installation drawing, and installing the fiber grating detectors at the bottom of an aeration disc; numbering the fiber grating detectors mounted at the bottom of the aeration disc, and drawing a fiber grating detector mounting diagram; carrying out real-time vibration detection on the aeration disc through the fiber grating detectors so as to find faults of the aeration disc in time, so that maintenance personnel can be dispatched to maintain the aeration disc, and the situation that the sewage treatment efficiency and quality are reduced is avoided; and detecting the aeration disc by using the fiber grating detectors, so that the problem that the detection cost is high when a diver dives into a pool for troubleshooting is solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment; in particular, it relates to a method for monitoring the health of aeration equipment in a sewage treatment plant based on grating temperature measurement. Background technique [0002] Fiber Bragg grating sensor is a kind of fiber optic sensor. The sensing process based on fiber Bragg grating is to obtain sensing information through the modulation of fiber Bragg wavelength by external physical parameters. It is a wavelength modulation fiber optic sensor. Fiber Bragg grating sensors can realize direct measurement of physical quantities such as temperature and strain. Fiber Bragg grating sensors can be attached to the surface of the structure or embedded in the structure in advance to perform health detection, impact detection, shape control and vibration damping detection of the structure, and monitor the structure. defective condition. [0003] At present, the aeration tanks of sewage ...
