Roots blower has high practical performance for aeration in small and medium-sized sewage treatment plants!

We can know that in the process of biological contact oxidation technology, the dissolved oxygen consumed by aerobic microorganisms in the process of oxidizing and decomposing organics, so it is necessary to supplement dissolved oxygen to sewage in a timely and effective manner. With microporous aerator, the oxygen transfer rate is 25% - 32%. Roots blower for sewage treatment aeration is a volume rotary blower, which is the basic information equipment for air blowing and oxygen transfer aeration in the process of biochemical index reaction research in sewage treatment plant. Its biggest feature is that when the pressure is allowed to develop within a certain range and adjusted, the change of flow has little impact, and the pressure situation has a wide range of use, which is characteristic of China's forced gas transmission.

The medium contains no oil. Simple structure, convenient maintenance, long service life, and low machine vibration. The medium conveyed by the blower is clean air, clean kerosene, sulfur dioxide and other gases. In view of the above characteristics, it can be widely used in the aeration process of various scale urban sewage treatment plants and the biochemical reaction process of small urban sewage treatment plants.

The Roots blower in the sewage treatment plant is simple in principle, simple in structure, stable in performance, and easy to manage and maintain. However, the safe operation and service life of the fan ultimately depend on the normal use and standard maintenance of the equipment. The three-level inspection system of equipment must be strengthened to deal with the abnormalities or hidden dangers found in time to ensure the safe, reliable and stable operation of the fan.

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