十二．罗茨鼓风机：
1．设置罗茨鼓风机，向污水处理设备及过滤器提供空气，风量满足整个系统需氧量

２．水泵型号：80YW40-15型液下泵；水泵设计流量：Q=45m3/h；水泵设计扬程：13m；电机功率：4.0kw。
第三节 设备的运行方式
整个污水处理系统为一套两组，两组可以同时运行，也可以分别单独运行，两组之间的切换根据需要（如检修其中一组）手动切换。正常单组运行时，一台污水提升泵运行，单组处理能力为5m3/h，两组同时运行时，若污水提升泵运行一台，则单组处理水量为2.5m3/h，若污水提升泵两台同时运行，则由人工打开其中一组的进水阀，以实现两组同时运行，此时每组处理能力为5m3/h。
整套污水处理设备的运行自动进行，值班员应定期对设备进行检查和维护。
第四节 各设备在处理过程中的作用及系统的调试运行
一．各设备在处理过程中的作用：
1．进入预曝调节池的污水，首先在池内进行预曝气，对水质有较好的均匀作用，同时可去除一部分污染物。
2．然后污水进入初沉池，对污水中较大颗粒，容易沉淀的悬浮物进行预沉处理，采用竖流式沉淀形式，上清液溢流进入一级接触氧化池，底部沉泥由气提升进入污泥池。
3．在生物接触氧化池，通过控制各阶段曝气量使池内保持高的溶解氧和优良的生物菌群与有机物接触反应环境，降解各类有机物污染。接触氧化池分为两段。
4．接触氧化池出水进入二沉淀池，澄清接触氧化池出水，形式采用竖流式沉淀池。底部污泥气提装置提升，一部分进入污泥池，一部分进入抽初沉池。
5．二沉池出水进入过滤池，截留去除污水中残余的悬浮物，同时对有机物也有一定程度去除。
6．过滤池出水进入消毒池，加入氯气，接触消毒。
7．消毒池出水流入清水池后排放，清水池储存一部分清水，供过滤池反冲洗。
8．污泥接纳沉淀的污泥池，上清液回流入调节池，进行再处理，沉积污泥约半年清理一次。
