Unpowered current-limiting intelligent intercepting well with overflow grating

Abstract

The invention discloses an unpowered current-limiting intelligent intercepting well with an overflow grating. The intelligent intercepting well comprises a sewage inlet pipe, the overflow grating, an overflow water outlet pipe, an unpowered current limiter, an intercepting sewage pipe and a partially filled pipe flow meter. The overflow grating is arranged in the well and located in front of a water outlet of the overflow water outlet pipe. The unpowered current limiter is arranged in the well and located in front of a water outlet of the intercepting sewage pipe. The partially filled pipe flow meter is arranged in the overflow water outlet pipe. The intercepting well reduces overflow pollution, the interception ratio is increased, pressure of a downstream sewage pipeline is relieved, the discharge amount of a combined system pipe network can be accurately limited, quantitative control of sewage or early-stage rainwater pollutants is achieved, remote operation can be achieved, maintenance and management work is reduced, and the intercepting well has the advantages that sewage interception is stable, impurity interception is remarkable, monitoring and operation are intelligent, and the intercepting well accords with national situations of China.

Description

technical field [0001] The invention relates to the technical field of interception wells, in particular to an intelligent interception well for confluent pipelines or divergent 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 discharged into the s...
