Abstract
The utility model discloses a short-tube intercepting system used for collecting rainwater in an early stage of a rainy season and collecting sewage on sunny days. The short-tube intercepting system comprises an intercepting main tube used for being connected with a sewage treatment plant, intercepting chambers used for being distributed at outlets of rainwater pipelines, and intercepting short tubes used for guiding sewage in the intercepting chambers into the intercepting main tube. The intercepting chambers distributed at the outlets of the different rainwater pipelines are in parallel connection with the intercepting main tube in a communicated mode through the respective intercepting short tubes, and the rainwater in the early stage of the rainy season and the sewage collected on the sunny days directly flow into the intercepting main tube through the intercepting chambers and the intercepting short tubes. According to the short-tube intercepting system, the sewage collected on the sunny days can directly flow into the intercepting main tube through the intercepting chambers and the intercepting short tubes and cannot be discharged into a river channel or a receiving water body, and accordingly reduces pollution to the water body. In the early stage of the rainy season, the rainwater with high pollutant concentration directly flows into the intercepting main tube through the intercepting chambers and the intercepting short tubes, is collected and processed by an early-stage rainwater treatment device downstream and then is discharged into the river channel or the receiving water body.
