Roots blower: the reliable power core of sewage treatment aeration system
In the aerobic biochemical treatment process of sewage treatment, continuous and stable aeration and oxygen supply is the core prerequisite for the degradation of pollutants by activated sludge. This Roots blower has become the preferred air supply equipment for aeration systems in various water treatment scenes by virtue of its positive displacement forced air blowing characteristics.
The fan has excellent pressure self-adaptive ability, and the boosting range can cover the normal aeration tank working conditions with a water depth of 4-8 meters. When the aeration head is blocked and the fluctuation of liquid level in the tank leads to the change of system resistance, the air volume can still be kept highly stable, and the deviation is controlled in a very small range, so as to continuously ensure the balance of dissolved oxygen concentration in the tank and avoid the load impact of the biochemical treatment system. The cavity is sealed and isolated, and the output gas is clean and oil-free, which will not cause secondary pollution to activated sludge flora and fully meet the requirements of water treatment process.
The whole machine integrates the intake filter muffler, exhaust muffler and safety valve assembly, which has low running noise and high safety redundancy; The integrated frame has stable structure, durable transmission parts, simple daily maintenance and can support long-term continuous operation. With the frequency conversion control scheme, the gas supply can be flexibly adjusted according to the fluctuation of influent quality and water quantity, and various treatment processes such as activated sludge process, SBR sequencing batch process and biological contact oxidation tank can be adapted, taking into account the treatment effect and operation energy consumption.
From aeration and oxygen supply in biochemical pool, sludge homogenization and stirring to backwashing of process pipeline, this Roots blower can cover the multi-link gas supply demand of sewage treatment, and provide core power support for the long-term standard operation of water treatment system with stable and reliable performance.
