Further, the top of described filtration beds is fixedly connected with described deflector, and filtration beds, when taking-up, conveniently takes out simultaneously, carries out cleaning to filtration beds by deflector.
Further, described filtration beds is the frame shaped that opening is arranged at top, when current are larger, ensure that the effective filtration to rainwater.
Further, the top of described filtration beds is detachably fixed on described inlet for stom water place.
Further, described nitrogen phosphorus adsorption structure is the structure of annular, both ensure that the effective absorption to nitrogen phosphorus, and can not affect blocking again.
Or described filtration beds is frame shaped, sidewall has two-layer screen pack, and screen pack is arranged at bottom, and the mesh diameter of bottom screen pack is greater than upper level filter net meshe diameter, and lower floor's screen pack mesh diameter is less than upper level filter net meshe diameter.
Operating principle of the present utility model is: set gradually deflector, filtration beds in the below of rain perforaled strainer, and is effectively adsorbed the nitrogen P elements in rainwater by nitrogen phosphorus adsorption structure, effectively reduces the pollution that rainwater causes river course; By filtration beds, the larger obstruction carried in rainwater is filtered, as silt, clay etc.
The beneficial effects of the utility model are:
1) by nitrogen phosphorus adsorption structure, the nitrogen P elements in rainwater is effectively adsorbed, effectively reduce the pollution that rainwater causes river course.
2) by filtration beds, the larger obstruction carried in rainwater and less foreign material are filtered, effectively prevent the blocking because impurity causes municipal pipeline.
3) by the setting of deflector, effectively ensure that rainwater is first flowed in municipal pipeline by filtration beds again.
