Description

Intercepting well with high interception rate

Technical Field

The utility model relates to the technical field of intercepting wells, in particular to a intercepting well with high interception rate.

Background

The intercepting well is one of means with better effect in the current water environment treatment and improvement measures; the main functions are as follows: during drought days, the sewage collected nearby is conveyed to a sewage plant through a cutoff pipe for treatment, and is discharged after reaching the standard; in rainy days, sewage and part of rainwater are trapped in the well, and the rainwater which is not trapped continues to flow downstream, and is discharged into a river after being diluted to reach a dischargeable standard; not only reduces the water pollution caused by sewage discharge, but also reduces the treatment load of sewage plants.

At present, most of the conventional common intercepting wells are intercepted in dry days through overflow weirs, but the non-adjustable overflow weirs block water flow in rainy days, so that the load of a sewage plant is increased during heavy rain, and overload leakage of the sewage plant is easily caused; the manufacturing cost of the electric control intercepting well or the intelligent intercepting well is high, and the electronic device is easy to damage under the corrosion of sludge and sewage for a long time.

A rain and sewage diversion intercepting well realizing self control through buoyancy is proposed in the patent with the application number of CN 202022844129.4; in the initial stage of rainwater, the lifting baffle is used for covering the discharge pipe, so that the rainwater enters the intercepting well and then enters a sewage treatment plant together with sewage; along with the gradual increase of the water quantity collected in the intercepting well, the water level in the intercepting well rises to enable the hollow floating ball to float, and the hollow floating ball drives the lifting baffle to move upwards to be opened while floating so that the water in the intercepting well is discharged outwards through the discharge pipe; the whole process is automatically controlled based on the hydraulic action, and the lifting baffle automatically restores to the original position after the flood peak is passed, so that the operation of other mechanical power or personnel is not involved, the structure is simple, and the operation is stable.

The technical scheme is characterized in that the automatic control based on the hydraulic action is used for intercepting, so that other mechanical power or personnel operation is not involved, and the structure is simple; however, as the sewage interception pipe does not adopt any measure for controlling the flow, along with the increase of the water quantity, the water flow can enter the sewage treatment plant from the sewage interception pipe preferentially, and the water flow can be discharged outwards only when the floating ball floats on the premise that the water quantity in the well continuously flows into the sewage interception pipe; the sewage plant receives large water quantity in the rainy days, overload operation of the sewage plant is easy to cause, and normal operation of the sewage plant is influenced.

As is known, the prior art has obvious inconvenience and defects in practical use, so that improvement is needed.
