在綜合污水處理系統(tǒng)設有斜管沉淀池，上層較清的廢水流入接觸氧化池，在接觸氧化池的底部通有曝氣管，使用曝氣羅茨風機進行供氣再處理，其中兩臺輪流工作；接觸氧化池中裝有填料，由于廢水的長期馴化，氧化池中的細菌得以生長并附著在濾料上，加上底部羅茨風機供應氧氣，使細菌進行有氧呼吸，消耗有機物，代謝產物通過沉降作用堆積到氧化池的底部，并通過底部的排泥閥進入污泥系統(tǒng)，這樣達到的二次處理的目的，使廢水中各項指標都顯著的下降了。接觸氧化池的上部接有管路，連接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.

池水進入CASS池后，行厭氧消化，使廢水中的氮、磷指標顯著下降，但是同時也會使COD、BOD有所上升；接下來的羅茨風機曝氣使之進入好氧區(qū)，此處是用一根管子插到池底，通過連接曝氣羅茨風機泵來進行供氧；在CASS池的大部分區(qū)域內，曝以空氣，上部加以原廢水，使其中的細菌對有機物充分的消化；

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池的底部裝有排泥泵，用以防止CASS池的污泥堆積，從泵里排出的污泥分兩路走，一路進入污泥系統(tǒng)，另一部分污泥回流進入CASS池，使CASS池的細菌數量保持在一定范圍，維持該群落的有效行。因為時刻都有細菌死去，所以羅茨風機提供的氣體必須是源源不斷的，需要無時無刻的補充。

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.

羅茨風機是容積式風機的一種，由兩個完全相同的三葉葉輪在由機殼和墻板密封的空間中相對轉動，由于葉輪與葉輪、葉輪與機殼、葉輪與墻板之間的間隙極小，從而使進氣口形成了真空狀態(tài)，空氣在大氣壓的作用下進入進氣腔，然后，每個葉輪的其中兩個葉片與墻板、機殼構成了一個密封腔，進氣腔的空氣在葉輪轉動的過程中，被兩個葉片所形成密封腔不斷地帶到排氣腔，又因為排氣腔內的葉輪是相互嚙合的，從而把兩個葉片之間的空氣擠壓出來，這樣連續(xù)不停的運轉，空氣就源源不斷地從進氣口輸送到出氣口，這就是羅茨風機的整個工作過程。

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.
