Description

Energy dissipation dam with pollutant removal capacity and energy dissipation purification method Technical Field The invention belongs to the technical field of energy dissipation dams, and particularly relates to an energy dissipation dam with pollutant removal capacity and an energy dissipation purifying method. Background At the present stage, the conventional energy dissipation sand basin commonly adopted at the water inlet end of the artificial lake body has single energy dissipation means, and is realized only through the water head loss along the passing surface and the water blocking retaining wall. The overflow water head is easy to cause cavitation damage of the plate surface in the descending process, and causes larger pressure on the water retaining wall. The step overflow energy dissipation dam is commonly used for energy dissipation of flood discharge bottom flow of a large hydropower station, the energy dissipation purpose is achieved through transverse swirling formed by water flow on a step and shearing and momentum exchange between the water flow and a main flow, and cavitation damage generated on a step surface can be effectively avoided and the inflow DO concentration is remarkably improved while the energy dissipation effect is enhanced due to the air entrainment of the water flow on the dam surface. With the rapid development of the urban process, a large amount of life and production wastewater containing refractory organic matters of high-concentration medicines and personal care products is discharged into a conventional sewage plant through a municipal pipe network and then is discharged into an aqueous environment after being treated by the sewage plant. However, conventional sewage treatment processes have difficulty in efficiently removing organic pollutants from medicines and personal care products in sewage, thereby causing gradual increase in the types and concentrations of residual refractory organic pollutants in water environments (lake water, river, reservoir water). The residual pollutants in the water environment mainly comprise various antibiotics, environmental estrogens, pesticides and other residual compounds, and the pollutants have long half-life period in the water environment and slow biodegradation, and have potential harm of acute carcinogenesis, deformity and mutation at a certain concentration. Meanwhile, after water enters the lake, the water is gradually enriched in a food chain of a steady-state system in the lake, and the endogenous steady-state maintaining capability of the lake is seriously influenced. At present, the conventional step overflow energy dissipation dam only plays a role in drop energy dissipation, and the flow rate of inflow at the water inlet end cannot be regulated and controlled independently in the process. Meanwhile, pollution indexes such as TP, TN, SS, refractory organic substances and the like brought by a water inlet end cannot be primarily removed, and the pollution indexes cause great influence on aquatic animals and plants in facilities such as back-end surface flow wetland and the like.
