Energy-saving integrated sewage pump station for river crossing and operation control method

Abstract

The invention discloses an energy-saving integrated sewage pump station for river crossing and an operation control method. According to the energy-saving integrated sewage pump station, a pump station base overflowing channel is obliquely arranged at the bottom of a water inlet well, and one side of the water inlet well communicates with a sewage inlet pipeline; a water pump drainage system is arranged in the water inlet well; the pump station base overflowing channel vertically communicates with a vertical water outlet pipeline; the vertical water outlet pipeline communicates with a U-shaped inverted siphon water outlet pipeline used for forming an inverted siphon to pass through the river, and the U-shaped inverted siphon water outlet pipeline is laid at the bottom of a riverbed; the water pump drainage system communicates with the U-shaped inverted siphon water outlet pipeline; and the other end of the U-shaped inverted siphon water outlet pipeline is connected with a water outlet well. According to the energy-saving integrated sewage pump station, the pump station and an inverted siphon river crossing mode are combined, then the design of the sewage pump station is optimized, and a pump station bottom silt prevention mode is creatively provided and is combined with a series of operation control methods.

Description

technical field [0001] The invention relates to the technical field of sewage pipelines, in particular to an energy-saving integrated sewage pumping station for crossing a river and an operation control method. Background technique [0002] With the gradual development of water environment improvement in cities, towns and rural areas, more and more projects have encountered the problem of sewage pipes crossing rivers. There are three ways for the existing sewage to cross the river: pumping station lifting to cross the river, inverted rainbow to cross the river, and increasing buried depth to cross the river along the slope from the bottom of the river. [0003] The pumping station is lifted to cross the river: the design of the pumping station is based on the most unfavorable conditions, the cost is high, and the energy consumption is high. [0004] Crossing the river with inverted rainbow: At present, there are two mainstream methods, the concave shape crossing the river a...

AI Technical Summary

Problems solved by technology

There are also projects that consider raising the upstream water level to carry out dredging, but this will cause high pressure on the operation and maintenance of upstream pipelines

[0005] Increase the buried depth and cross the river from the bottom of the river along the slope: this method is an ideal way to cross the river, but the application conditions are narrow

Under normal circumstances, the buried depth of the downstream of the pipeline will be increased, and the cost of the entire sewage pipeline system will increase exponentially
