Abstract

The invention relates to the technical field of water environment treatment, in particular to an intelligent dissolved oxygen regulating and controlling device for water environment treatment and a method adopting the intelligent dissolved oxygen regulating and controlling device. The intelligent dissolved oxygen regulating and controlling device comprises a DO detecting probe, a data collecting module, a parameter editing module, a data processing module, a display module, a data storage module, a controlling and regulating module, an equipment control module, a valve control module, an electromagnetic valve and aeration equipment. Water dissolved oxygen can be autonomously and intelligently controlled and regulated, the dissolved oxygen is controlled within the dissolved oxygen range achieving most vigorous aerobic bacterium physiological activity and metabolism all the time, the operating energy consumption of the equipment can be reduced, and the running efficiency of the equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to an intelligent control device for dissolved oxygen and an intelligent control method for dissolved oxygen for water environment treatment. Background technique [0002] In today's rural water environment treatment, the water quality and water volume of the water environment treatment facilities will fluctuate greatly. If the incoming water directly enters the water environment treatment facilities, it will cause the various treatment modules of the water environment treatment process to fail to meet the pollution requirements. effect of the treatment. In the aerobic chamber of the water environment treatment facility, the change of the amount of water in the aerobic chamber will cause the change of the dissolved oxygen content in the water body, and the change of the dissolved oxygen amount can lead to the following two situations: [0003] (1) Too much incom...

AI Technical Summary

Problems solved by technology

[0003] (1) Too much incoming water leads to low dissolved oxygen in the aerobic chamber, which will inhibit the physiological activity and metabolic growth of aerobic bacteria in the aerobic chamber, resulting in insufficient activity and quantity of aerobic bacteria in the aerobic chamber, resulting in pollution Incomplete treatment of pollutants, resulting in substandard discharge of pollutants, black or smelly effluent

[0004] (2) The amount of dissolved oxygen in the aerobic chamber is too high due to too little incoming water, which will increase the physiological activity of aerobic bacteria in the aerobic chamber, accelerate the metabolic growth, and cause the metabolism of aerobic bacteria to be too fast, resulting in the amount of sludge discharged from the sedimentation tank Increase

[0006] (1) The amount of dissolved oxygen in the aerobic chamber cannot be effectively controlled within a stable range. The amount of dissolved oxygen is either too high or too low. It is difficult to maintain the optimal amount of dissolved oxygen for aerobic bacteria

[0007] (2) Time control cannot achieve precise regulation of dissolved oxygen, and the opening time needs to be continuously adjusted artificially based on experience and water flow

[0008] (3) Continuous aeration will cause waste of energy consumption, and may also cause excessive dissolved oxygen, reduced activity of aerobic bacteria, and reduced water treatment capacity
