Intelligent on-demand pure oxygen aeration system and method for pond

Abstract

The invention discloses an intelligent on-demand pure oxygen aeration system and method for a pond. The system comprises the pond, a pure oxygen source, a water quality online and intelligent pure oxygen aeration control cabinet, an aeration assembly and a dissolved oxygen sensor, the aeration assembly comprises a water pump, aerators, a pure oxygen pipe and high-oxygen water outlet pipes, and each high-oxygen water outlet pipe is provided with a plurality of high-oxygen water outlets. A water pump is arranged at the edge of the pond and is connected with a plurality of the aerators, the water quality online and intelligent pure oxygen aeration control cabinet is respectively connected with the pure oxygen source and aerator pipelines, each aerator is connected with one high-oxygen water outlet pipe arranged in the pond, and the dissolved oxygen sensor is arranged near each group of the high-oxygen water outlet pipes. The water pump and the dissolved oxygen sensor are both in signal connection with the water quality online and intelligent pure oxygen aeration control cabinet. A digital and intelligent on-demand pure oxygen aeration mode is adopted, the dissolved oxygen problem of the pond is solved, the water quality is improved, the yield can be stabilized or improved, the effect of guiding production is truly achieved, the maintenance period is prolonged, and energy is saved.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to an intelligent on-demand pure oxygen oxygenation system and method for ponds. Background technique [0002] At present, open-air ponds basically use air oxygenation to increase the overall dissolved oxygen level of the pond. However, practice has shown that the traditional air oxygenation method has the following problems: [0003] 1. In the high temperature season, air oxygenation cannot ensure that the dissolved oxygen in the overall water body of the pond is within a reasonable range, which greatly affects the yield, feeding coefficient and water quality of the pond; [0004] 2. The dissolved oxygen in ponds that use air oxygenation is unstable and cannot be maintained in a constant range, so that the water body will deteriorate due to low dissolved oxygen at night and in rainy days, and the cost of tail water treatment in the later stage will be relatively high; ...

AI Technical Summary

Problems solved by technology

[0003] 1. In the high temperature season, air oxygenation cannot ensure that the dissolved oxygen in the overall water body of the pond is within a reasonable range, which greatly affects the yield, feeding coefficient and water quality of the pond;

[0004] 2. The dissolved oxygen in ponds that use air oxygenation is unstable and cannot be maintained in a constant range, so that the water body will deteriorate due to low dissolved oxygen at night and in rainy days, and the cost of tail water treatment in the later stage will be relatively high;

[0005] 3. Air oxygenation will inject harmful components in the air into the water at the same time, which will also cause the deterioration of the water quality in the pond, and further increase the cost of tail water treatment in the later stage;

[0006] 4. The process of oxygenation tends to be manual and manual. The dissolved oxygen value and temperature value in the pond cannot be displayed in a centralized digital real-time display on the terminal. The opening and closing of the oxygenation system requires manual control by workers with experience. More cumbersome and heavy workload;

[0007] 5. The performance of the dissolved oxygen sensor used is unstable, the life is short, and the error is large, which cannot truly reflect the significance of the sensor guiding production, and often requires manual cleaning work, the maintenance cycle is short, and the maintenance workload is large
