AERATION APPARATUS FOR SEWAGE TREATMENT PLANT

摘要

PURPOSE: To manufacture an aeration apparatus for sewage treatment plant that is able to improve the efficiency of rotational air blow system and disposal efficiency of wastewater by having more extending time of the provided air in the wastewater. CONSTITUTION: The apparatus comprises a body(15) which has a fixed width and height to make it possible inflow and outflow of wastewater; an air diffuser(21) which has an air exhaust nozzle(20) and is installed at the bottom of the body to remove organic and inorganic substances in the wastewater by blowing air; an inclination plate(30) which is installed with an inclination of 5-10 degrees to the air exhaust nozzle to extend the residence time of air. Furthermore, the inclination plate is apart from the exhaust nozzle by 20-30cm and is apart from the wall of the body by 20cm; a blower(40) which is connected with the air diffuser to supply outside air to the wastewater; and a heater(50) which is installed between the air diffuser and the blower to heat the air.
