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

Abstract

The invention discloses an intrusion-prevention intelligent intercepting well with slag blocking and unpowered current-limiting functions. The intrusion-prevention intelligent intercepting well comprises a sewage inlet pipe, an intrusion-prevention regulating weir, a floating slag blocking device, an overflow water outlet pipe, an unpowered current limiter and an intercepting sewage pipe, wherein the intrusion-prevention regulating weir is arranged in the well and is positioned in front of a water outlet of the overflow water outlet pipe; the floating slag blocking device is arranged in the well, and is positioned between the intrusion-prevention regulating weir and the sewage water inlet pipe; the unpowered current limiter is arranged in the well, and is positioned in front of the intercepting sewage pipe. The intercepting well provided by the invention has the advantages that the overflow pollution can be reduced; the intercepting times are reduced; the downstream sewage pipeline pressure is reduced; the discharge quantity of a combined system pipe network can be accurately limited; the quantitative control of sewage or primary rainwater pollutants can be realized; the remote operation and control can be realized; the maintenance and management work is reduced. The intercepting well has the characteristics of intercepting sewage stability, intrusion-prevention function operation stability, obvious floating object intercepting effect and intelligent supervision and operation, and is suitable for national conditions in China.

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...
