Roots blower is a positive displacement blower with simple structure and forced air supply. It can adapt to pressure changes in sewage treatment applications and is often used for sewage treatment aeration in environmental protection projects.

水处理罗茨风机主要是往水中曝气来提高水中氧气的含量，先除去可氧化的沉淀的物质，作用是增加含氧量，通过曝气让水和空气充分接触，以交换气态物质和去除水中挥发性物质的水处理方法，使气体从水中逸出，如去除水的臭味或二氧化碳和硫化氢等有害气体；或使氧气溶入水中，以提高溶解氧浓度，达到除铁、除锰或促进需氧微生物降解有机物的目的。

The Roots blower for water treatment is mainly used to aerate the water to increase the oxygen content in the water. First, the oxidizable precipitated substances are removed. Its function is to increase the oxygen content. Through aeration, the water and air are fully contacted to exchange gaseous substances and remove volatile substances in the water. The water treatment method allows the gas to escape from the water, such as removing the odor of water or harmful gases such as carbon dioxide and hydrogen sulfide; Or dissolve oxygen into water to increase the concentration of dissolved oxygen and achieve the purpose of removing iron and manganese or promoting aerobic microorganism to degrade organic matter.\

罗茨鼓风机在污水处理工程中是核心设备，风机的工作效能能够直接决定污水处理的效果，生物法处理污水，为了促进好氧微生物的生长，必须提供充足的氧气，好氧微生物能够促进代谢作用的发生，分解污水中的悬浮物及氮磷等有机化合物。

Roots blower is the core equipment in the sewage treatment project. The working efficiency of the blower can directly determine the effect of sewage treatment. In order to promote the growth of aerobic microorganisms in sewage treatment, sufficient oxygen must be provided. Aerobic microorganisms can promote the occurrence of metabolism and decompose suspended solids, nitrogen and phosphorus and other organic compounds in sewage.

罗茨鼓风机是污水处理过程中必要的核心设备，直接决定污水处理效果与能耗。生物法污水处理流程中主要使用罗茨鼓风机用于曝气池增氧，促进好氧微生物生长，通过它们的代谢作用分解污水中的悬浮物、溶解性有机物以及氮磷等营养盐等达到污水处理的目的，是污水处理厂的核心设备。使用的风机性能的好坏对我们处理的污水质量与能耗有着直接的影响。

Roots blower is the necessary core equipment in the sewage treatment process, which directly determines the sewage treatment effect and energy consumption. Roots blower is mainly used in the biological sewage treatment process to increase oxygen in the aeration tank, promote the growth of aerobic microorganisms, and decompose suspended solids, dissolved organic matter, nitrogen and phosphorus and other nutrients in the sewage through their metabolism to achieve the purpose of sewage treatment. It is the core equipment of the sewage treatment plant. The performance of the fan used has a direct impact on the quality and energy consumption of the sewage we treat.

罗茨风机在低压力段（50kpa以下）效率好，而且造价低，具有良好的性价比。所以罗茨鼓风机适用于以下污水处理场合：第①、曝气压力较低的情况下（50kpa以下），或者排气压力高但使用时间不长。第二、工况变化大，要求变频范围广。第三、工况生产需要频繁启停。

Roots blower has good efficiency in low pressure section (below 50kpa), low cost and good cost performance. Therefore, Roots blower is applicable to the following sewage treatment occasions: ①. When the aeration pressure is low (below 50kpa), or the exhaust pressure is high but the service time is not long. Second, the working conditions vary greatly, requiring a wide range of frequency conversion. Third, production under working conditions requires frequent start and stop.
