Urban sewage is a product of urban development. A large amount of sewage is dumped into water bodies and soils, destroying the natural ecology of water bodies and soils, causing the disappearance of water species, the disappearance of fish and shrimps, the disappearance of fish and shrimps, the accumulation of heavy metals and toxic substances in the soil, and the pollution of pollutants through the food chain. Our physical health has caused huge economic losses, which has constrained the sustainable development of urban social economy, and we have to carry out sewage treatment projects to improve our living environment. Blast aeration is a key parameter control in wastewater treatment, and there are many parameters affecting aeration, such as influent load, sludge mud and so on. Dissolved oxygen has hysteresis, and it is more complicated to automatically control the number of fans to start and stop and change the air volume with a dissolved oxygen meter. The control of this parameter is very important. It is necessary to use advanced technology to control this, and the aeration control power consumption accounts for about 80% of the sewage plant. It is also a trend to reduce consumption through control.
