Roots blower for sewage treatment plays a big role in the environmental protection industry and is highly efficient!

We know that in biological contact oxidation treatment, dissolved oxygen is consumed by aerobic microorganisms when they oxidize and decompose organics, so it is necessary to supplement dissolved oxygen to sewage in time. With microporous aerator, the oxygen transfer rate is 25% - 32%. Roots blower for sewage treatment It is a volume rotary blower, and is the basic equipment for air blowing, oxygen transfer and aeration in the biochemical reaction process of the sewage treatment plant. Its biggest feature is that when the pressure is adjusted within the allowable range, the flow changes little, the pressure selection range is wide, and it has the characteristics of forced gas transmission.

The medium is free of oil when transported by Roots blower. Simple structure, convenient maintenance, long service life and low vibration of the whole machine. The Roots blower for sewage treatment can transport clean air, clean kerosene, sulfur dioxide and other inert gases. In view of the above characteristics, it can be widely used in the process of aeration and sand settling in various scale urban sewage treatment plants and the blast aeration in the biochemical reaction process of small urban sewage treatment plants.

Although the three blade roots blower is simple in principle and structure, it has stable performance and is easy to manage and maintain. However, the safe operation and service life of the blower ultimately depend on the normal use and standardized maintenance of the equipment. It is necessary to strengthen the three-level patrol inspection system of the equipment, and deal with abnormalities or hidden troubles in a timely manner to ensure the safe, reliable and stable operation of the blower.

First of all, roots blower for sewage treatment must be started under no-load condition. Before starting, open all air inlet and exhaust valves of the fan. After starting normally, gradually adjust the valves to make the air volume reach the required value. It is not allowed to adjust the air volume to the rated air volume at one time. Roots blower for sewage treatment shall not be shut down suddenly under full load operation. It must be shut down after gradually reducing the air volume to avoid damaging the fan.
