The purpose of Roots blower for sewage treatment aeration is to get enough dissolved oxygen in the water body to contact with the gas, so as to carry out the process of dissolved oxygen or disperse dissolved gases and volatile substances in the water. So, Roots blower for sewage treatment What are the methods? In the activated sludge process of wastewater, the dissolved oxygen in the mixed liquor shall be supplied by aeration method. The role of Roots blower in sewage treatment is mainly to provide fully dissolved oxygen for aerobic bacteria in the water body, and provide power for stirring the mixture in the aeration tank. Silver is widely used in the aeration treatment of industrial wastewater such as paper making, textile, printing and dyeing, electroplating, viscose fiber, food processing, fermentation and brewing, as well as urban domestic sewage.
The aeration methods used in the activated sludge aeration tank can be divided into bubble aeration method and mechanical aeration method. In the process of biological treatment of wastewater by the activated sludge process of the equal line bubble aeration method and bubble aeration method, microporous aeration heads, rotary cutting aeration heads or microporous aeration tubes are arranged at or near the bottom of the aeration tank. Due to the larger immersion depth of the diffuser producing microbubbles, and the resistance of the diffuser micropore increases. Therefore, the required Roots blower pressure is high. Its oxygenation efficiency is generally 10% - 30%.
Mechanical aeration refers to the method of fully mixing wastewater and sludge in the activated sludge aeration tank with mechanical equipment, and constantly updating the liquid level of the mixed solution to contact with the air, so as to increase the dissolved oxygen in the water.
The oxygen in the atmosphere enters the liquid by means of the mechanical action of blades, impellers, sprayers or turbine devices. At present, the widely used aerators are mainly surface aerators and submerged turbine aerators. Roots blower for sewage treatment is relatively easy to use.
