PURPOSE: An apparatus for synthetically pre-treating sewage is provided to improve the processing efficiency by continuously filtering waste and sediment while maintaining the flow of waste water. CONSTITUTION: A sediment sand sinking unit(130) is distanced from a bottom plane of a body(110) at a predetermined interval, and a pump(132) circulates the water and sewage through a main pipe(134). A discharge pipe(136) forms a slope angle of 45 degree through the main pipe. The sewage and wastewater is circulated in the discharge pipe through the water in the main pipe. A blocking check valve(138) is installed at the end portion of the main pipe. |
