Abstract

The invention discloses a sewage dissolved oxygen tester based on online control. The tester structurally comprises a water taking pipe, a heat conduction metal strip, a water suction pipe, a floatingring, a solar cell panel, a vacuum pump, a wireless control module, a tester and an equipment main body, the water intake pipe is mounted at the bottom of the equipment main body; the heat conductionmetal strip is embedded and mounted outside the equipment main body; the water suction pipe is connected with the interior of the equipment main body; the floating ring is mounted on the equipment main body; according to the invention, the remote terminal is used for controlling; therefore, frequent back-and-forth running of personnel in a test site and a test bench is avoided; the efficiency isgreatly improved firstly; the potential safety hazard existing in a personnel travel test site is avoided; and through wireless remote control, wired connection is avoided, interference of the site environment is small, a wired connecting wire is prevented from being corroded or damaged, sampling detection and comprehensive comparison can be conducted on detection pools with different water pressures and water depths through the tester, specific data of a detection site are analyzed accordingly, and data errors are reduced.

Description

technical field [0001] The invention is a sewage dissolved oxygen measuring instrument based on online control, which belongs to the field of sewage detection. Background technique [0002] Amperometry measures the dissolved oxygen (DO) content in water based on the diffusion rate of molecular oxygen through a membrane. The film of the dissolved oxygen electrode can only pass through the gas, and the oxygen in the gas diffuses into the electrolyte, and the reduction reaction occurs immediately on the cathode (positive electrode); O2+2H2O+4e→4OH-, on the anode (negative electrode), such as An oxidation reaction occurs on the silver-silver chloride electrode: 4Ag+4Cl-→4AgCl+4e. The current generated by the above two formulas is proportional to the concentration of oxygen. By measuring this current, the concentration of dissolved oxygen (DO) can be obtained. [0003] The prior art discloses a portable dissolved oxygen meter whose application number is: 201820716644.4. There i...
