Intrusion-prevention intelligent intercepting well with slag blocking and unpowered current-limiting functions

Abstract

The invention discloses an anti-backflow intelligent interception well with the functions of slag blocking and unpowered flow limiting, which comprises a sewage inlet pipe, an anti-backflow regulating weir, a floating slag stopper, an overflow outlet pipe, a non-powered flow limiter, and an intercepted sewage pipe, the anti-backflow regulating weir is set in the well and before the water outlet of the overflow outlet pipe; the floating slag catcher is set in the well, and is located between the anti-backflow regulating weir and the sewage inlet pipe; the unpowered flow limiting The device is arranged in the well and before the water outlet of the shut-off sewage pipe. The interception well of the present invention reduces overflow pollution, increases the interception multiple, slows down the pressure of the downstream sewage pipeline, can accurately limit the discharge of the combined pipe network, realizes quantitative control of sewage or initial rainwater pollutants, and can realize remote control, reduce The maintenance and management work has the characteristics of stable interception of sewage, stable operation of anti-backflow function, remarkable interception of floating objects, intelligent supervision and operation, and adapting to China's national conditions.

Description

technical field [0001] The invention relates to the technical field of interception wells, in particular to an anti-backflow intelligent interception well for combined pipelines or separate rainwater pipelines. Background technique [0002] For the combined drainage pipe network or the separate rainwater pipe network, because the mixed sewage or initial rainwater carries a large amount of particulate pollutants from sources such as urban surfaces, roofs, domestic sewage, and pipeline sediments, these particulate pollutants have not been Any interception and direct discharge into the receiving water body of the city will cause pollution to the receiving water body. Therefore, it is necessary to intercept the combined pipe network or the separate rainwater pipe network, and set a certain interception multiple so that the intercepted sewage or initial rainwater is discharged into the terminal sewage treatment plant, and the water exceeding the interception capacity is discharge...

AI Technical Summary

Problems solved by technology

At the same time, the traditional interception wells in the existing technology are simple and extensive, and the management level is low, and remote control cannot be realized, which increases the maintenance and management work
