Description

Novel dissolved oxygen on-line analyzer

Technical Field

The utility model relates to a dissolved oxygen analyzer equipment technical field specifically is a novel dissolved oxygen on-line analyzer.

Background

The molecular oxygen dissolved in the air in water is called dissolved oxygen, the content of the dissolved oxygen in the water has close relation with the partial pressure of the oxygen in the air and the temperature of the water, under the natural condition, the oxygen content in the air does not change greatly, so the water temperature is the main factor, the lower the water temperature is, the higher the content of the dissolved oxygen in the water is, the molecular oxygen dissolved in the water is called dissolved oxygen, generally called DO, and expressed by the milligram of the oxygen in each liter of the water;

the amount of dissolved oxygen in water is an index for measuring the self-purification capacity of water, and the dissolved oxygen generally has two sources: one source is that when the dissolved oxygen in water is not saturated, oxygen in the atmosphere permeates into the water body; the other source is oxygen released by aquatic plants through photosynthesis, so dissolved oxygen in water can be continuously supplemented due to dissolution of oxygen in air and photosynthesis of green aquatic plants, but when a water body is polluted by organic matters and is seriously consumed by oxygen, the dissolved oxygen cannot be timely supplemented, anaerobic bacteria in the water body can be rapidly propagated, the water body becomes black and smelly due to corruption of the organic matters, the dissolved oxygen value is a basis for researching the self-purification capacity of the water, the dissolved oxygen in the water is consumed and is required to be recovered to an initial state, the required time is short, the self-purification capacity of the water body is strong, or the water body is not seriously polluted, the self-purification capacity is weak, or even the self-purification capacity is lost;
