在综合污水处理系统设有斜管沉淀池，上层较清的废水流入接触氧化池，在接触氧化池的底部通有曝气管，使用曝气罗茨风机进行供气再处理，其中两台轮流工作；接触氧化池中装有填料，由于废水的长期驯化，氧化池中的细菌得以生长并附着在滤料上，加上底部罗茨风机供应氧气，使细菌进行有氧呼吸，消耗有机物，代谢产物通过沉降作用堆积到氧化池的底部，并通过底部的排泥阀进入污泥系统，这样达到的二次处理的目的，使废水中各项指标都显著的下降了。接触氧化池的上部接有管路，连接CASS池。

There is a inclined sedimentation tank in the comprehensive sewage treatment system, where the upper layer of relatively clear wastewater flows into the contact oxidation tank. An aeration pipe is connected to the bottom of the contact oxidation tank, and an aeration Roots fan is used for gas supply and treatment. Two of them work in rotation; The contact oxidation tank is equipped with fillers. Due to the long-term domestication of wastewater, bacteria in the oxidation tank can grow and adhere to the filter material. In addition, the bottom Roots blower provides oxygen, allowing bacteria to engage in aerobic respiration and consume organic matter. Metabolites accumulate at the bottom of the oxidation tank through sedimentation and enter the sludge system through the bottom sludge discharge valve, achieving the goal of secondary treatment, The various indicators in the wastewater have significantly decreased. The upper part of the contact oxidation tank is connected to a pipeline, which is connected to the CASS tank.

池水进入CASS池后，行厌氧消化，使废水中的氮、磷指标显著下降，但是同时也会使COD、BOD有所上升；接下来的罗茨风机曝气使之进入好氧区，此处是用一根管子插到池底，通过连接曝气罗茨风机泵来进行供氧；在CASS池的大部分区域内，曝以空气，上部加以原废水，使其中的细菌对有机物充分的消化；

After the pool water enters the CASS tank, anaerobic digestion is carried out, which significantly reduces the nitrogen and phosphorus indicators in the wastewater, but also increases COD and BOD; The following Roots blower is aerated to enter the aerobic zone, where a pipe is inserted into the bottom of the pool and oxygen is supplied by connecting the aerated Roots blower pump; In most areas of the CASS pool, air is exposed and raw wastewater is added to the upper part to allow bacteria to fully digest organic matter;

在CASS池的底部装有排泥泵，用以防止CASS池的污泥堆积，从泵里排出的污泥分两路走，一路进入污泥系统，另一部分污泥回流进入CASS池，使CASS池的细菌数量保持在一定范围，维持该群落的有效行。因为时刻都有细菌死去，所以罗茨风机提供的气体必须是源源不断的，需要无时无刻的补充。

A sludge pump is installed at the bottom of the CASS tank to prevent sludge accumulation. The sludge discharged from the pump is divided into two paths, one entering the sludge system and the other returning to the CASS tank, keeping the bacterial count in a certain range and maintaining the effective operation of the community. Because bacteria die at all times, the gas provided by the Roots blower must be continuous and constantly replenished.

罗茨风机是容积式风机的一种，由两个完全相同的三叶叶轮在由机壳和墙板密封的空间中相对转动，由于叶轮与叶轮、叶轮与机壳、叶轮与墙板之间的间隙极小，从而使进气口形成了真空状态，空气在大气压的作用下进入进气腔，然后，每个叶轮的其中两个叶片与墙板、机壳构成了一个密封腔，进气腔的空气在叶轮转动的过程中，被两个叶片所形成密封腔不断地带到排气腔，又因为排气腔内的叶轮是相互啮合的，从而把两个叶片之间的空气挤压出来，这样连续不停的运转，空气就源源不断地从进气口输送到出气口，这就是罗茨风机的整个工作过程。

Roots blower is a type of volumetric fan, which consists of two identical three bladed impellers rotating relative to each other in a space sealed by the casing and wall panel. Due to the extremely small gap between the impeller and the impeller, the impeller and the casing, and the impeller and the wall panel, a vacuum state is formed at the inlet, and air enters the inlet chamber under the action of atmospheric pressure. Then, two of the blades of each impeller form a sealing chamber with the wall panel and the wall panel, During the rotation of the impeller, the air in the intake chamber is continuously carried to the exhaust chamber by the sealing chamber formed by the two blades. Because the impellers in the exhaust chamber mesh with each other, the air between the two blades is squeezed out. This continuous operation continuously transports air from the inlet to the outlet, which is the entire working process of the Roots fan.
