Abstract
A multilayer aerobic undercurrent bed includes water inlet tanks, water outlet tanks and filling and feeding tanks; the undercurrent bed is formed by superposed combination of more than one aerobic undercurrent bed unit layer; wastewater is treated by the aerobic undercurrent bed unit layers, then enters the water inlet tank of a lower aerobic undercurrent bed unit layer from the water outlet tank of an upper aerobic undercurrent bed unit layer through siphon pipes and successively flows through all the aerobic undercurrent bed unit layers step-by-step, and the whole process of undercurrent bed aerobic treatment is completed. According to the problem of large land occupied area of conventional aerobic treatment, the multi-layer aerobic undercurrent bed is designed, so that aerobic treatment layout is changed to stereo layout from plane layout, space is fully utilized, and the land occupied area of wastewater treatment is greatly reduced. Wastewater re-oxygenation is generated by utilization of flowing process in the wastewater treatment process and through siphon effect and other effects, and the purpose of wastewater aerobic treatment is achieved; and due to adopting of the siphon technology, operation energy consumption is greatly saved.
