Buoyancy-controlled rainwater and sewage distribution cabin

Technical Field

The invention relates to the technical field of urban rainwater and sewage separation, in particular to a buoyancy-controlled rainwater and sewage separation cabin.

Background

At present, urban rainwater and sewage are shunted, and the urban rainwater and sewage tend to be refined and modified in detail in the direction. The balcony vertical pipe mixed connection and the private pat of the shops along the street in cities and towns are used as main mixed flow sources, and the problems of difficult exploration, difficult transformation and difficult supervision always exist.

The balcony stand pipes of the high-rise building are buried in the wall body, exploration is difficult, the concrete mixed connection position is difficult to judge for transformation, and the newly-built stand pipes are high in risk and high in construction difficulty, so that interception is generally adopted as a standing measure. However, the traditional intercepting well is a municipal facility with an intercepting weir as a main component, and the capacity for changing the Moscout weather condition in the south of the Yangtze river should be poor. The phenomena of the top drop of the sewage pipeline and the river descending of the sewage pipeline are easily caused in rainy days. In rainy seasons, pipeline sediments scour and overflow into rivers, settle river bottoms, generate odorous gases such as hydrogen sulfide and ammonia gas under anaerobic conditions, lake bodies, recesses and creeks with rain and sewage discharge ports are black and odorous, lake bodies are heavily eutrophicated, and urban water environment quality and water ecological landscape are seriously affected. The traditional intercepting well can achieve the effect only by meeting the design requirement that a sewage pipe network is lower than a rainwater pipe network, has poor adaptability and is far from meeting the variable conditions encountered in construction, and if a rainwater pipe is lower than the sewage pipe, the intercepting well cannot be adopted as a rainwater and sewage diversion measure; there is automatically controlled distribution of rain and sewage device in the market, but management and maintenance cost are high, especially are not applicable to the occasion that needs set up distribution of rain and sewage device in a large number such as each resident's building, and in addition, current distribution of rain and sewage device sensitivity also is difficult to improve, and the rainwater is difficult for triggering when not reaching a certain extent greatly.
