- 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.
