Germany utilizes the common rain water pipe to collect rainwater, from the roof, the rainwater collected of street, parking lot and passage enters underground storage tank by storm sewer independently on every side, most typical measure is to build a large amount of stormwater tanks to hold back the contaminated rain water of handling combined system and segregation system piping, and takes the ecological measure in distributing source to cut down and purify rainwater.After simple process, be used to wash the lavatory and water and spill garden.
Denmark collects rainwater in the urban area from the roof, and the rainwater after the collection enters storage cistern and stores through the pre-filtering equipment of collecting pipe bottom.Filter through the float-type strainer during use, be used to wash the lavatory and wash clothes.
The Japanese flood storage pond of building flood detention and savings rainwater since 1963, also the rainwater with flood storage pond is used as city miscellaneous waters such as spraying road surface, irrigation greenery patches.These facilities are built in underground mostly, to make full use of the underground space.
China's Application of Urban Rain Water is started late, and the making use of rain and flood of big and medium-sized cities is in substantially to be explored and conceptual phase.Cities such as Beijing, Shanghai, Dalian, Xi'an conduct a research in succession.At the beginning of nineteen ninety, Beijing has carried out " making use of rain and flood research " subject study.By the effect Primary Study that roof-seepage well system and lawn are retained the rain flood, the countermeasure and the technical measures of Beijing City making use of rain and flood have been proposed.
Above-mentioned prior art exist to some extent or structure comparatively complicated, or handle the relatively poor defective of effect of rainwater.
The utility model content
The purpose of this utility model is to provide a kind of sand filtration wall formula split rainwater treatment system, and the main means that adopt the sand filtration wall construction to handle as rainwater reduce main polluted factors SS and COD in the rainwater to reach MnPurpose.
Overall technical architecture of the present utility model is:
Sand filtration wall formula split rainwater treatment system comprises being arranged on the rainwater collection channel 1 that is no more than ground surface that the settler that sets gradually along water (flow) direction and communicate with each other, reservoir are provided with filtration beds in reservoir; Filtration beds is the sand filtration wall that the reservoir middle part vertically is provided with, this sand filtration wall is separated into rain collecting pool spaced apart 5 and clear water reserviors 8 with reservoir, and this sand filtration wall comprises that vertically stacked permeable coarse sands layer 10 and the fine sand layer 13 of each one deck at least of 8 directions formed along rain collecting pool 5 to clear water reserviors.
What need further specify is, the utility model is including, but not limited to reasonably being provided with the middle layer of sand of effective level as required between coarse sands layer 10 and fine sand layer 13, gravel particle diameter in the middle layer of sand is between the gravel particle diameter of coarse sands layer and fine sand layer, gravel in each deck of sand filtration wall does not break away from essence of the present utility model according to being arranged to thin principle by thick along the rainwater water (flow) direction.
Concrete technology solution of the present utility model also has:
For the typing of assurance sand filtration wall and the location between each deck, preferred embodiment be that the sand filtration face of wall is coated with location silk screen 11, is provided with between adjacent coarse sands layer 10 and the fine sand layer 13 to separate silk screen 12.
Preferred gravel particle size range is: the gravel particle diameter in the coarse sands layer 10 is 12-17mm, and the gravel particle diameter of fine sand layer 13 is 10-15mm.
Be to guarantee that the dirty rainwater of mistake in the rain collecting pool 5 flows into clear water reserviors 8, the preferred construction mode is the sand filtration wall to fix with bottom reservoir, and the joint portion of the two is a non-permeable solid wall structure 14.
For preventing that the foul in the rainwater collection channel from too much flowing in the rain collecting pool 5, settler preferably with rainwater collection channel 1 be communicated with separately or the sedimentation basin 3 of connecting at interval.
For preventing from accidentally dirt to be dropped sedimentation basin 3, preferred embodiment be that sedimentation basin 3 upper surfaces are provided with Grate plate 2.
For preventing from accidentally dirt to be dropped reservoir 3, be convenient to water and maintenance simultaneously, the reservoir upper surface is provided with protective cover 6, and protective cover 6 surfaces offer the inspection hole 4 that is communicated with reservoir.
For reach the purpose of water intaking more conveniently, the water-supply-pipe 7 that preferred water-supply method is a submersible pump is arranged in the reservoir, and its water side mouth 4 on inspection is opened in the reservoir outside.
The obtained technological progress of the utility model is:
1, adopts split-type structural, fully realized a pond two purposes: water that to spill garden low to water quality requirement, can directly use the rain collecting pool rainwater; Greenery patches irrigation and flushing lavatory are higher to water quality requirement, can utilize the clear water reserviors rainwater.Simultaneously, adopt and divide box collection rain, be convenient to clean, saving of labor, laborsaving has significantly reduced rainwater water treatment expense.
2, build the sand filtration wall in the reservoir, carry out filtration treatment to harvesting rainwater, the blank wall of effective height is left in gravel wall bottom, can effectively avoid dirty rainwater to flow into clear water reserviors, in order to discharging after rainy season or cleaning.
