1、 Aeration machine
Aeration machine is one of the commonly used mechanical and electrical equipment in sewage treatment plants. Its main function is to transport oxygen from clean water to the water to promote the growth and metabolism of bacteria in the water. There are different types and operating modes of aerators, and some common aerators include mechanical aerators, blower aerators, and wall mounted aerators.
2、 Sludge reflux pump
The sludge reflux pump is a commonly used electromechanical equipment in sewage treatment plants, whose main function is to send the treated sludge back to the treatment tank and allow it to continue to participate in the treatment process. The sludge reflux pump usually uses a centrifugal pump, and the flow rate and speed can be adjusted as needed.
3、 Flotation machine
Flotation machine is a commonly used electromechanical equipment in sewage treatment process, whose main function is to separate solids and liquids. There are various structures and forms of flotation machines, and different working methods can be selected according to different requirements for treating wastewater.
4、 Filter press
Filter press is also a commonly used electromechanical equipment in sewage treatment plants. Its main function is to dehydrate the treated sludge to reduce its moisture content. There are different types and operating modes of filter presses, including belt filter presses, plate and frame filter presses, drum filter presses, etc.
There are various types of mechanical and electrical equipment in sewage treatment plants, and each type of equipment has its unique role and purpose. In addition to the aforementioned equipment, sewage treatment plants also require the use of various mechanical and electrical devices such as water pumps, control valves, and pipelines to complete the entire sewage treatment process.
