Function of aeration roots blower in sewage treatment
1、 What is aeration
In the process of sewage treatment, certain methods and equipment are used, Roots blower Forced air is introduced into the sewage water to make the sewage in the pool contact with the air for oxygen filling, and stir the liquid to accelerate the transfer of oxygen in the air to the liquid, prevent the sinking of suspended objects in the pool, strengthen the contact between organic matters in the pool and microorganisms and dissolved oxygen, and oxidize and decompose the organic matters in the sewage. The process of forced aeration to the sewage water is called aeration
2、 Oxygen filled roots blower
Activated sludge process is an aerobic biological treatment method. It is necessary to rely on aerobic microorganisms to absorb the organic matter in water, and oxidize and decompose to form carbon dioxide and water, while allowing its own proliferation and reproduction. In this process, it is necessary to provide enough dissolved oxygen to microorganisms in activated sludge to meet the needs of microbial growth and metabolism. Roots blower Aeration first realizes the process of oxygen transportation, which transfers oxygen from air to water through gas water contact. Therefore, the calculation of air volume in blast aeration is based on microbial oxygen demand, combined with environmental conditions, water quality conditions, aeration efficiency and other transfer factors.
We may all know that in sewage treatment, we need to input air into the water through aeration blower, etc. But as for the reason why air should be imported, many people may not know. therefore Roots blower The manufacturer will talk about the specific purpose of the air input in the blast aeration.
In the sewage treatment industry, because the sewage aeration tank needs oxygen to be oxidized and decomposed by microorganisms, in the sewage treatment industry, Roots blower According to different water depth and tonnage, oxygen can be provided to promote the oxidative decomposition of microorganisms. Roots blower It is the core equipment of sewage treatment. Roots blower The efficiency of sewage treatment can directly determine the effect of sewage treatment.
In order to promote the growth of aerobic microorganisms, it is necessary to provide enough oxygen. Aerobic microorganisms can promote metabolism. This action occurs and decomposes suspended solids and organic compounds, such as nitrogen and phosphorus, in sewage.
On the one hand, the aeration tank makes the sludge in the aeration process in full contact with the sludge to enhance the mass transfer effect in the water treatment system. On the other hand, it provides good conditions for the diffusion and transfer of oxygen in the liquid phase.
Summary: Roots blower It is an essential core equipment in sewage treatment process, which directly determines its effect and energy consumption. In the process of biological wastewater treatment, Roots blower It is mainly used in aeration tank to increase oxygen, promote the growth of aerobic microorganisms, and use it to metabolize and decompose suspended solids, dissolved organic matter, nitrogen and phosphorus and other nutrients in wastewater to realize wastewater treatment. The purpose is the core equipment of sewage treatment plant. The performance of the fans we use directly affects the quality and energy consumption of the sewage we treat.
