Abstract

The invention discloses a floating solar wireless water environment chemical oxygen demand monitoring method. The method comprises the following steps: water sampling is performed through a solar floating constant temperature automatic water quality sampling device; a liquid to be tested is injected into a photoelectric machine visual unit; reagent in a reagent bottle is injected into the photoelectric machine visual unit through a micro pump array; the liquid to be tested and the reagent are mixed; the liquid to be tested is observed and monitored through an LED (light-emitting diode) light source in a photoelectric machine visual testing chamber and a micro color camera; data analysis is performed according to program commands of an embedded system so as to obtain the test result; and finally the liquid to be tested is recovered through a liquid recovery chamber. The method has the benefits that firstly a water solar floating system and an energy management unit are realized, so that solar energy can be obtained from water of field environment, the problem of automatic on-line monitoring to environment water quality COD parameters is solved, the convenience in distribution and unmanned property are realized, and the method is suitable for monitoring large-scale water area.

Description

technical field [0001] The invention belongs to the field of water quality monitoring, in particular to a floating solar wireless water environment chemical oxygen demand monitoring method. Background technique [0002] The so-called chemical oxygen demand (COD) is the amount of oxidant consumed when a certain strong oxidant is used to treat water samples under certain conditions. It is an indicator of the amount of reducing substances in water. Reducing substances in water include various organic matter, nitrite, sulfide, ferrous salt, etc. But mostly organic matter. Therefore, chemical oxygen demand (COD) is often used as an index to measure the content of organic substances in water. The greater the COD, the more serious the water body is polluted by organic matter. [0003] In the prior art, the most commonly used method is acidic potassium permanganate oxidation. Potassium permanganate (KmnO4) method has a low oxidation rate and can be used to determine the relativ...
