Description
Technical Field
The invention relates to the technical field of dissolved oxygen monitoring equipment, in particular to a dissolved oxygen monitoring and oxygen supply system which has good economy, high input-output ratio, convenient operation and complete functions and is suitable for large-scale high-density aquaculture and can reduce manual aquaculture.
Background
The source of dissolved oxygen in the culture water body is photosynthesis, and when sunlight is sufficient in the daytime, the strong photosynthesis of floating algae and aquatic plants in the water generates a large amount of oxygen, which is the main source of dissolved oxygen in the culture water body. On sunny days with higher water temperature, dissolved oxygen can even reach more than 20ml/L, and a supersaturated state is formed. Secondly, artificial oxygenation, mechanical oxygenation of an aerator, filling of new water with high dissolved oxygen and sprinkling of an oxygenation agent. Relationship between oxygen and fish growth in aquaculture water: taking four large fishes as an example, the four large fishes grow normally when dissolved oxygen is 5 mg/L, and the ingestion amount is reduced by 13% when the dissolved oxygen is reduced by 1 mg/L, which is equivalent to 13 jin in hundred jin of feed, and the waste is caused. When the fish live at a concentration of more than 5 mg/L, the feed is saved by 20% and the growth speed is also increased by 20% -30% compared with the feed live at a concentration of 3 mg/L. The higher the Dissolved Oxygen (DO) is, the better, and when the saturated dissolved Oxygen (OS) is reached, the Dissolved Oxygen (DO) in water is not increased any more, so that waste is caused. The Dissolved Oxygen (DO) is too high, so that fish can get ill, and the Dissolved Oxygen (DO) is maintained within a certain range.
The existing dissolved oxygen monitoring method is not suitable for large-scale high-density aquaculture by manually checking the concentration of the dissolved oxygen, supplying oxygen at fixed time and adjusting the oxygen supply time and time length according to seasonal changes.
Application number: 200910198413.4, filing date: 2009-11-06 discloses a method for monitoring and regulating dissolved oxygen in an aquaculture pond, and particularly relates to a method for monitoring and regulating dissolved oxygen in an aquaculture pond. A method for monitoring and regulating dissolved oxygen in an aquaculture pond comprises the steps of configuring an upper water layer exchange device, a lower water layer exchange device and an aerator in a standard rectangular aquaculture pond, arranging upper layer sampling points, middle layer sampling points and lower layer sampling points in the pond according to a specified rule, and configuring monitoring sensors on the sampling points; processing test data of the sensor; judging the result of the test data processing according to the breeding objects and weather, and opening or closing the upper and lower water layer exchange equipment according to the regulation to open or close the aerator.
