Fig. 1 is the system structure diagram of the utility model.
Wherein:1- inlet pipelines;21- strainers;22- deflectors;23- slopes;24- level-ones settling zone;25- two-stage precipitations Area;26- three-levels settling zone;31- floating drums;32- filter assemblies;33- slide gates;34- guide rails;4- outlet pipelines;5- inspection sockets.
Specific implementation mode
A kind of separation of rainwater and oil removing system shown in referring to Fig.1, including piece-rate system and it is connected to piece-rate system two The inlet pipeline 1 and outlet pipeline 4 at end.
The piece-rate system includes solid separation and precipitation area and oil removing Disengagement zone;The solid separation and precipitation area includes precipitation Area and the screening area above settling zone;Level-one settling zone 24, two-stage precipitation area 25 are divided into the settling zone successively And three-level settling zone 26.
The top of the level-one settling zone 24, two-stage precipitation area 25 and three-level settling zone 26 is interconnected;Level-one settling zone 24, two-stage precipitation area 25 and the bottom surface of three-level settling zone 26 be towards the inclined slope 23 in 4 direction of outlet pipeline, while it is each It is equipped with deflector 22 on the inner wall of settling zone, to avoid in low discharge or high flow capacity heavy, pollution has been settled to bottom Object causes to wash away strongly and settling flux is caused to reduce the removal effect to pollutant.
The level-one settling zone 24 is adjacent with inlet pipeline, is equipped in the screening area and level-one settling zone 24 and two level sink The strainer 21 of the top covering in shallow lake area 25, strainer 21 is for intercepting and collecting floating material larger in rainwater, the top of strainer 21 It can be connected through the hinge with bottom, it is convenient to open and close at any time.
The three-level settling zone 26 is adjacent with outlet pipeline 4, and the oil removing Disengagement zone is located at the top of three-level settling zone 26, Filter assemblies 32 and lifting current-limiting apparatus are equipped in oil removing Disengagement zone, the filter assemblies 32 are porous type filter packing, position Below the nozzle of outlet pipeline 4, the lifting current-limiting apparatus lifts current-limiting apparatus between filter assemblies 32 and strainer 21 Including the guide rail 34 being arranged in a vertical direction and the slide gate 33 being movably connected on guide rail 34, on the slide gate 33 It is fixed with floating drum 31, slide gate 33 is lifted with the lifting of water level along guide rail 34.
Three inspection sockets 5 are additionally provided at the top of piece-rate system, to facilitate the observation to internal system.
The operation principle of the utility model is as follows:
In rainfall, initial rainwater is entered through rain perforaled strainer in Storm Sewer Network by urban road surfaces, the tree on road surface The pollutants such as the sundries such as leaf, the scraps of paper, pop can and the organic and oils after washing away are entered with rainwater through inlet pipeline 1 together In piece-rate system, rainwater enters in the strainer 21 in screening area first, and strainer 21 can intercept floating material larger in removal rainwater, Initial rainwater after filtering intercepts drops into level-one settling zone 24 again, and after precipitation, proportion larger pollutant in part will settle To bottom have slope sedimentation basin bottom, with the continuous entrance of rainwater, level-one settling zone 24 will be filled, subsequent stormwater overflow into Enter to two-stage precipitation area 25, some of the contaminants which does not remove enter three followed by rainwater Grade settling zone 26, in the region by the pollutant in further removal rainwater.
It is provided with deflector 22 in level-one settling zone 24, two-stage precipitation area 25 and three-level settling zone 26, can avoid rainwater The settling flux of pollutant has been settled to bottom of pond and has reduced the removal effect to pollutant.
Constantly rise with the water level of three-level settling zone 26, rainwater can enter the oil removing separation of 26 top of three-level settling zone Area, by filter assemblies 32, the oil pollutant contained in rainwater is intercepted by the filter packing of the porous type in filtration system And absorption is then discharged from the outlet pipeline of top 4 to reduce the pollutant load of oils in rainwater.
As water is continuously increased in storm sewer, the water level in piece-rate system is also gradually increasing, at this point, except oil From in area, the floating drum 31 of fixed glides gate 33 starts slowly to be move upwardly until opening, such later stage rainwater along guide rail 34 Since pollutant concentration continuously decreases, rainwater can be directed across by the top of filter assemblies 32, through 4 discharge system of outlet pipeline, Improve treatment effeciency.
After rainfall, the strainer 21 in screening area is opened, the floating material being intercepted in strainer 21 falls into settling zone, passes through Well enters settling zone bottom to suction-type sewer scavenger suction tube on inspection, and the pollutant of deposition and floating material are pumped away together.In addition, Periodically the porous type filter packing in oil removing Disengagement zone is replaced, to restore and provide filtering and adsorb oil pollutant Ability.
The preferable specific implementation mode of the above, only the utility model, but scope of protection of the utility model is not limited to In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in Change or replace, should be covered within the scope of the utility model.Therefore scope of protection of the utility model is with claim Subject to the protection domain of book.
