Rain and sewage flow splitting automatic control device

Abstract

The invention provides a rain and sewage flow splitting automatic control device. The rain and sewage flow splitting automatic control device comprises a rain and sewage flow confluence pipe, an overflow device and a lever adjusting mechanism, wherein a water inlet pipe of the overflow device is communicated with the rain and sewage flow confluence pipe; a water outlet pipe of the overflow device is communicated with a sewage discharging pipe; the lever adjusting mechanism is arranged on the overflow device; when the water level of a river channel is lower than a certain threshold value, the lever adjusting mechanism enables the overflow device to be opened, water in the rain and sewage flow confluence pipe is discharged from the sewage discharging pipe through the water outlet pipe; when the water level of the river channel is equal to or higher than the certain threshold value, the lever adjusting mechanism enables the overflow device to be closed, the water in the rain and sewage flow confluence pipe is discharged into the river channel. According to the rain and sewage flow splitting automatic control device provided by the invention, automatic flow splitting of rain and sewage is realized depending on natural rising and falling of the water level of the river channel; both electric driving and manual action are not needed, the opening and the closing of the overflow device are very flexible, the installation and debugging of the overflow device are simple, the manufacturing cost is low, and a practical value is obtained.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a rain and sewage diversion automatic control device, which is suitable for black and odorous river treatment, rainwater regulation and storage, and municipal drainage projects. Background technique [0002] With the improvement of living standards, sewage treatment plants have been popularized in towns and villages, and the main domestic sewage and industrial wastewater are all sent to sewage treatment plants for centralized treatment. However, the drainage system of many ancient cities is to discharge washing sewage, catering, other flushing sewage and rainwater to the sewer and discharge them into the water body. The rainwater and sewage pipes are not completely separated, and there is still a phenomenon that some sewage and rainwater merge into the river, such as Washing sewage, roadside catering washing sewage, etc. all flow into the river, causing serious ...

However, the drainage system of many ancient cities is to discharge washing sewage, catering, other flushing sewage and rainwater to the sewer and discharge them into the water body. The rainwater and sewage pipes are not completely separated, and there are still some phenomena that sewage and rainwater merge into the river, such as Washing sewage, roadside catering washing sewage, etc. all flow into the river, resulting in serious pollution of the non-point source water of the river, the water loses its self-purification ability, and becomes black and smelly water
