传感器优化曝气池的运行效率

曝气池是什么？

曝气池是污水处理过程中的关键设施，通过将压缩空气打入污水中来提供氧气，可促使微生物分解污水中的有机物质，达到污水净化的效果。当压缩空气被打入水中后，会产生大量气泡，这些气泡不仅携带氧气进入水中，还促进水体的循环，增加氧气的扩散范围，进一步提升微生物的活性和代谢效率。曝气池是活性污泥法（activated sludge process）中的核心环节，其运作效率直接影响污水处理系统的整体效果。

曝气池的重要性

曝气池的主要作用在于有效降解有机物，并去除水中的氮、磷等营养物质，防止水体优养化。压缩空气的持续供应既提供氧气，也因气泡的形成而促进水体混合循环，保障氧气能够均匀分布，以满足微生物的代谢需求。然而，压缩空气的供应需要大量能源，因此精确控制其供应量不仅可以节省能耗，还能提升处理效果并降低运营成本。适当的溶氧量是曝气池维持高效率的关键，过高的溶氧量会使压缩空气的能耗显著增加，造成不必要的能源浪费和运营成本上升。

为什么需要传感器？

传感器在曝气池中发挥关键作用，提供实时的溶解氧、风速和风量数据，帮助操作人员精确适应压缩空气的供应量。这样可以确保氧气和水流的分布均匀，同时避免不必要的能源浪费。随着压缩空气成本增加，传感器的应用有助于减少多余空气的输入，进一步降低能源消耗，并延长设备的使用寿命，提升污水处理系统的经济性与稳定性。

传感器应用于曝气池

1. 平均风速测管搭配差压传感器
平均风速测管具有多孔设计，可提供曝气池管道内的均匀气流测量，避免了仅靠单点测量所带来的数据偏差，确保气流分布更符合实际需求。结合差压传感器后，能实时回馈气流变化，从而调整曝气量以减少能源浪费，同时避免过量曝气对生物系统的影响。再搭配具有Relay功能的显示控制器使用，可实现更精确的气流监测与自动控制，使曝气系统的运行更加智能化。

2. 风速风量传感器
曝气池的氧气供应由空压机负责，风速风量传感器用于监测打入池内的空气量。风速风量传感器能确保氧气供应是否稳定且充足，以维持微生物的代谢效率。同时，避免过量氧气供应造成的能源浪费。

3. 液位传感器
液位传感器用于监控曝气池的液位，确保水位处于最佳范围，保持水质处理的稳定性。这有助于提高曝气效率，并防止处理系统过载。

这些传感器的应用不仅能够精准监控曝气池的运行参数，还能帮助污水处理厂实现智能化管理，显著提升处理效率，降低能耗，并确保排放达到环保标准。
