Deck runoff collection and treatment and emergency system have two kinds of duties: take and process the emergent accident treatment state that conventional deck runoff pollutant is revealed as dangerous substances such as main conventional rainfall treatment state, generation poisonous and harmfuls.
During conventional rainfall treatment state, souring due to rainfall formation in early stage runoff, it is comparatively serious that deck runoff has the phase pollution, the characteristics that the later stage runoff is comparatively clean, native system will pollute comparatively serious antecedent precipitation and will be collected in adjusting-emergency lagoon 7, main process is as follows: runoff was flowed through and was shunted pond 2 by shunting pond water inlet pipe 1 early stage, because adjusting-emergency lagoon 7 is now empty, float valve 6 is open mode, sewage enters adjusting-emergency lagoon 7 by shunting pond 2, after this adjusting-emergency lagoon 7 middle water levels constantly rise, when water level meets or exceeds the peak of syphon 10, syphon starts and forms " self priming pump " automatically, after this as long as the interior water level of adjusting-emergency lagoon 7 does not reach the water inlet of syphon 10, sewage in adjusting-emergency lagoon 7 just flows into sedimentation basin 14 with certain flow through overflow weir baffle plate 16 water distribution uniformities, due to the flow of siphonal flow much smaller than delivery port 3, when rainfall continues, the water level of adjusting-emergency lagoon 7 still rises steadily, when the water level of adjusting-emergency lagoon 7 reaches float valve action water level, delivery port 3 is closed, now, early stage, sewage collecting was complete, shunting pond 2 is filled with, later stage sewage directly flows out water pipe 4 through shunting pond 2 by the anaphase bridge face diameter and directly enters gutter, enter into the surrounding environment water body.The attendant is by controlling the open size of syphon valve 17, can regulate-emergency lagoon 7 in sewage enter horizontal sedimentation tank 14 flows and flow velocity.After rainfall finishes, syphon will be generally a few hours in several days in the long period, and the sewage in adjusting-emergency lagoon 7 is drawn in horizontal sedimentation tank 14.In horizontal sedimentation tank, sewage is precipitated or is carried out further manpower intervention processing, discharge.
When system during in the emergent accident treatment state, the dangerous substances such as poisonous and harmful are revealed and form runoff on bridge pavements, because the amount of accident generation sewage is less, foregoing process, when if sewage quantity does not reach the syphon tip position, all sewage is just collected in adjusting-emergency lagoon 7, in order to processed, if the amount of accident generation sewage is slightly large, owing to being provided with valve 17 on syphon 10, the staff gets involved in time, closes syphon valve 17, and the accident sewage of making is stored in adjusting-emergency lagoon 7.
, because adjusting-emergency lagoon 7 and the particulate pollutant of horizontal sedimentation tank 14 depositions are constantly accumulated, need to regularly be cleared up after a period of time in system works, when system need to be safeguarded, can be removed contamination by the emptying unlatching of atmospheric valve 12 arranged.
