The uniform dissolution of oxygen, avoid single ecological floating island area it is excessive when cause chinampa decentralization illumination insufficient and make organic matter degradation
The problems such as insufficient；Peripheral chinampa 2 and center chinampa 3 are provided with multiple progress of anchors 4 position and fix, and ecological floating island is avoided to exist
Position over-deflection on the water surface and be brought together and be even overlapped.
The utility model introduces setting after rainwater conflux is entered the drainpipe connecting with discharge outlet by the discharge outlet of bridge floor
Catch basin in bridge side, catch basin are retained rainwater into Boosting pumping station in a manner of tubule abandoned stream.It is original using landform and bridge floor
Device bridge floor initial rainwater is collected, solve the problems, such as that bridge floor rainwater is difficult to collect.
Boosting pumping station setting grid in rainwater floating material and biggish suspended matter intercepted and/or crushed removal
Afterwards, the biggish inorganic particle precipitation and separation of specific gravity in rainwater is removed using sand setting equipment and grit water separator.Removal is large-scale solid
The bridge floor initial rainwater of body rubbish is sent into sump and carries out runoff investigation, then using the water level control degreasing unit of sump to
Bubble is passed through in rainwater, grease, which is adsorbed on bubble, forms the froth bed containing grease contamination in the water surface, collects froth bed removal
Rainwater after oil removing makes fine suspension in rainwater by the way that medicament is added in clarifying equipment and is attached to suspension
Impurity and pollutant on object formed biggish colloid flocculation object net catch, roll up sweep suspended matter tiny in rainwater after precipitate and go
Finally, rainwater enters rainpool ecological floating island combination region, rainpool and the artificial floating plant and microorganism led are utilized
Absorb organic matter, nutrient and the fine particulates decomposed in removal rainwater.
Abandoned stream collection is carried out to bridge floor initial rainwater using height difference by the collection pipe network being arranged on bridge in this way, after collection
Initial rainwater by removal floating material and biggish suspended matter after remove the biggish inorganic particle of specific gravity in initial rainwater again,
Then water is adjusted, then removes the grease contamination in initial rainwater, then remove the fine suspension in initial rainwater
And it is attached to impurity and pollutant on suspended matter, it is up to standard after deliquescent pollutant in last intensified ecological removal initial rainwater
Discharge.The different pollutants in bridge floor initial rainwater are removed respectively by multi-step, so that bridge floor initial rainwater is final
