Problems solved by technology

Excessively high dissolved oxygen will accelerate the consumption of organic matter in sewage, causing microorganisms to age due to lack of nutrients. Long-term excessively high dissolved oxygen will reduce the flocculation performance and adsorption capacity of activated sludge, increase energy consumption, and cause suspended solids Settling property becomes poor, effluent water quality deteriorates; the level of dissolved oxygen is too low, which will reduce the activity of sludge, which will inhibit the degradation of organic matter by organisms and cause sludge bulking. Therefore, the optimal control of DO concentration is realized, and the effect of sewage treatment and running costs are very meaningful
