Description

Rain sewage cut-off equipment

Technical Field

The utility model relates to a rain sewage converging pipeline technical field that dams, concretely relates to rain sewage cut-off equipment.

Background

The intercepting well is a centralized well, namely, a plurality of inspection wells which produce pollution are centralized into one well, and the well is integrated and then led to a sewage treatment plant for sewage treatment. Catch basins are used in combined rain and sewage systems in order to catch up sewage and part of the initial rain. In dry seasons, only sewage exists in the pipe, and the intercepting well can intercept the sewage and flow the sewage to a sewage treatment plant for sewage treatment; in rainy season, part of rainwater and sewage are intercepted and flow into a sewage pipe, and the rest of water flows into a river through a weir in the well.

In the prior art, an intercepting well used in a rainwater and sewage combined system generally controls the opening and closing of a rainwater discharge valve by detecting the rainfall during rainfall or the water level in the intercepting well during rainfall. When the rainfall is not or is smaller, the water quantity in the intercepting well is smaller, the water level in the intercepting well is lower than the elevation of the overflow pipe at the moment, and all the water in the intercepting well is discharged into a downstream sewage treatment plant through the intercepting pipe; when the rainfall is larger, the water quantity in the intercepting well is increased, the water level is raised and is higher than the elevation of the bottom of the overflow pipe, so that the water in the intercepting well flows into a downstream river from the overflow pipe. However, in practical applications, this type of flow splitting is not reasonable. In the area with light pollution, when the rainfall is small or no rain, the concentration of water in the intercepting well is lower, the pollutants are less, and at the moment, the water in the intercepting well is introduced into the sewage plant, so that the concentration of part of water received by the sewage plant is too low, the normal operation of the sewage plant is influenced, and the energy production of sewage treatment facilities is wasted. In a region with heavy pollution, when the rainfall amount is large but the rainfall time is short, the concentration of water in the intercepting well is still high, but the water level in the intercepting well rises to be higher than the elevation of the bottom of the overflow pipe, so that the water with high concentration and heavy pollution is discharged into a downstream river system through the overflow pipe, and the river is polluted.
