Quality and quantity differentiating flow guide tank used for high-pollution rainwater and drought flow sewage

Abstract

The invention discloses a quality and quantity differentiating flow guide tank used for high-pollution rainwater and drought flow sewage. The flow guide tank is of a sealed rectangular structure; a water inlet hole and a water outlet hole are formed in the two vertical end faces of the flow guide tank respectively; a U-shaped groove is formed under the connection part of the water inlet hole and the flow guide tank; a pollutant detection probe is arranged in the U-shaped groove; a liquid level meter is arranged on the vertical central position of the flow guide tank and on the same side wall of the pollutant detection probe; a flow guide hole is formed in the water outlet hole side of the flow guide tank and in the bottom of the same side wall of the liquid level meter; the flow guide hole is sequentially connected with a self-suction pump and a reversing valve. According to the flow guide tank, a concentration control mode and a liquid level control mode are adopted, so that the efficiency of guiding the high-pollution rainwater and the drought flow sewage is maximized; a control concentration parameter is set, so that quantitative flow guide control can be indirectly realized; meanwhile, a city river way water body landscape is beautified.

Description

technical field [0001] The present invention relates to water resource treatment facilities, in particular to a diversion device for high-polluted rainwater and dry-flow sewage in urban rainwater pipe networks and rainwater pumping stations. Background technique [0002] As an important part of the city, the urban river water body has a huge impact on the life and production of urban residents. However, due to the pollution of rainwater runoff and the presence of pollutants deposited in drainage pipes washed by sewage during dry flow, most of today's urban river water bodies are polluted to varying degrees, making urban ecological environment construction more difficult. [0003] With the gradual deepening of the research on the impact of urban runoff pollution on urban water bodies, the problem of rainwater pollution in urban drainage pipes and the deposition of pollutants due to low flow in the dry season have begun to attract attention. The existence of sediments in urba...
