PURPOSE: A membrane separation sewage treatment device using an ultrasonic wave deaerator and method thereof are provided to reduce construction and maintenance cost while improving nitrogen removal efficiency. CONSTITUTION: A membrane separation sewage treatment device using an ultrasonic wave deaerator comprises a flow control bath(11), an anaerobic tank(12), a membrane separation aeration tank(14), an anoxic bath(13), and a separation bath(22). The flow control bath supplies raw water. The anaerobic tank processes organic compounds or phosphorous with the raw water. The membrane separation aeration tank performs a nitrification process and a solid-liquid separation process. The separation bath receives an ultrasonic device(51) or sludge for 5 minutes. |
