Application background The content of dissolved oxygen is related to water temperature, oxygen partial pressure, salinity, water depth, water depth, and organic concentration of oxygen consumption. dissolved oxygen content in water is affected by two kinds of effects: one is the oxygen consumption of DO, which includes aerobic degradation of organic substances, biological oxygen consumption; the other is to increase the effect of DO, the main air dissolved oxygen, water plants, etc.. The interaction of these two kinds of interactions, so that the dissolved oxygen content in water presents a temporal and spatial change. in natural condition, water in the flow, the complex oxygen process is more rapid, more easy to add water oxygen consumption, so that the water dissolved oxygen to maintain a certain level, and vice versa, in still water conditions, the complex oxygen process is slow, the oxygen in the water can not be added, in
