Abstract

The invention discloses a drop energy dissipating shaft for sand setting pretreatment. The drop energy dissipating shaft for sand setting pretreatment comprises a management room, a ventilating equipment room, a deodorizing equipment room, an operating room, a drop energy dissipating room and a deep-layer storage regulation tunnel from top to bottom, wherein the drop energy dissipating room comprises a water inlet pipe, a water inlet well, a grid room, a braiding channel and a dissipating well communicating with each other sequentially; and a sand setting tank and a grab type grid are arrangedin the grid room. The drop energy dissipating shaft for sand setting pretreatment disclosed by the invention is characterized in that multiple functions such as pretreatment, drop energy dissipation,ventilation, deodorization, an electricity transformation and distribution room, a control room and a management room are arranged in an overall structure, thereby realizing multiple targets such asreduction of engineering construction difficulty, intensive use of land and easy operation and management.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to a falling water energy-dissipating vertical shaft for sand settling pretreatment. Background technique [0002] With the development of industrial economy and the discharge of waste water in people's daily life, the rivers in many cities have been seriously polluted, and this phenomenon is common throughout the country. In order to prevent river pollution, it is necessary to collect initial rainwater and dry sewage. The common methods are diversion rainwater system and combined rainwater and sewage system. [0003] However, in the separate rainwater system or the rainwater combined system, when the rainfall in rainy days is large and exceeds the capacity of the drainage system, the excessive rainwater (confluent sewage) is directly discharged into the river. This creates two problems: [0004] First of all, due to the high concentration of pollutants in the initial rainw...
