WASTEWATER DISPOSAL PLANT FOR OXIDATION DITCH USING OXIDATION DITCH AND METHOD FOR CONSTRUCTING THE SAME

摘要

PURPOSE: A wastewater disposal plant for oxidation ditch using oxidation ditch and method for constructing the same are provided, which can construct aeration tank and settling tank by precast concrete plates thus eliminating the required curing time of concrete and excluding any exterior restrictions such as season. The equipment can also construct settling tank in the aeration tank thus saving construction area. CONSTITUTION: The wastewater disposal plant for oxidation ditch comprises an exterior wall(12) made of a plural precast concrete plates to form a circle; an inner wall(22) formed inside the exterior wall(12) by a plural precast concrete plates to provide a settling tank(20), between the exterior and inner walls(12,22) an aeration tank(10) being provided. The plurality of concrete plates(14,24) are vertically installed by fasteners to form the exterior wall(12) and inner wall(22) respectively. The fasteners are boxes set at one end of concrete plates(14,24) and pipes through which wire rope is inserted into the boxes to fasten the concrete plates(14,24).
