Automatic drainage intercepting well

Abstract

The invention relates to an automatic drainage intercepting well. The automatic drainage intercepting well comprises a well chamber and a closed well cover, wherein the well chamber is internally divided into a transition chamber, a sewage chamber, a primary rain chamber and an overflow chamber; the transition chamber is located at the upper part of the well chamber; the sewage chamber, the overflow chamber and the primary rain chamber sequentially communicates and are arranged at the lower part of the well chamber; the bottom wall of the transition chamber is provided with an overflow hole respectively communicating with the sewage chamber and the overflow chamber; a first driving mechanism and a second driving mechanism are arranged in the transition chamber; a water inlet pipe communicating with the transition chamber is arranged on the side wall of the transition chamber; and a sewage outlet pipe, an overflow outlet pipe and a primary rain outlet pipe correspondingly communicate with the lower parts of the side walls of the sewage chamber, the overflow chamber and the primary rain chamber respectively. According to the automatic drainage intercepting well, sewage in sunny daysand rainy and polluted mixed sewage in rainy days are automatically classified and intercepted, and thus subsequent sewage treatment facilities and primary rainy treatment facilities can convenientlycarry out targeted treatments; and meanwhile, water in a downstream pipeline or a water body is not prone to forming backflow in the intercepting well, so that the treatment load of the subsequent treatment facilities is reduced, and the treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to an automatic drainage interception well. Background technique [0002] The interception well in the interception combined drainage pipe network system is one of the important facilities in the system. The drainage interception well is generally installed at the end of the combined drainage pipe network system. Its function is to mix the sewage in sunny days or the rain and sewage at the beginning of rainfall The same interception pipe is used for interception, and the rain and sewage mixed sewage caused by the increase of rainfall in the middle and later periods of rainfall exceeds the drainage capacity of the interception pipe to overflow. [0003] Traditional drainage interception wells often have the following problems: (1) The interception method of traditional drainage interception wells is generally weir-type or groove-type interception. These two methods general...

Problems solved by technology

[0003] Traditional drainage interception wells often have the following problems: (1) The interception method of traditional drainage interception wells is generally weir-type or groove-type interception. These two methods generally lower the elevation of the interceptor pipe to achieve interception, so it is easy to cause downstream pipelines or The water in the water body forms a backflow in the interception well and enters the sewage interception pipe and then enters the sewage treatment plant, which will not only increase the treatment load of the sewage treatment plant and change the influent water quality, but also affect the treatment effect of the sewage treatment plant; (2 ) did not realize the separation and interception of sunny sewage and rain-sewage mixed sewage in the early stage of rainfall, but were directly discharged into the same set of sewage pipeline system downstream. The concentration of rain and sewage mixed sewage pollutants is much higher than that in sunny sewage. If it is directly discharged into the downstream sewage pipeline, it will have a great impact or even damage the subsequent sewage treatment plant.
