摘要:
某采用Orbal氧化沟工艺的污水处理厂，采用转碟表面曝气，由于设备老化导致运行效率低、能耗较高。后将原有的表面曝气改造为底曝+推流的曝气形式。为不影响污水处理厂正常运行，改造采用可提升的管式曝气器。改造后的污水处理厂出水水质稳定达到一级A排放标准，平均每月节省电耗约34×104 kW·h，大大降低了污水处理厂运营成本。
Abstract:
A wastewater treatment plant (WWTP) using Orbal oxidation ditch process with rotating disc aerator for surface aeration, has low operating efficiency and high energy consumption due to equipment aging. Then the original surface aeration was transformed into the aeration mode of bottom aeration and push flow. In order to avoid affecting the normal operation of the wastewater treatment plant, the liftable tubular aerators were used. The effluent quality of the WWTP after retrofitting stably met the first level A standard. The average monthly power consumption was reduced by about 34×104 kW·h, which greatly reduced the operating cost of the WWTP.
