Description
Technical field
It is the invention belongs to environment protection architecture technical field, more particularly to a kind of from irrigation roof rainwater collection cleansing and recycling dress
It sets.
Background technology
In recent years, as the fast development of urban construction, urban garden and green space system are drastically reduced, the life of the nature hydrology is destroyed
State balances, and the regions such as greenery patches, wetland, irrigation canals and ditches with water conservation function are largely evolved into hardened ground originally, cause city
City is only capable of draining by city planting ductwork when facing heavy showers.There are rainwater resources to be lost in city at present, flood frequency
Hair, the problems such as rainwater runoff pollution is serious.Water resource waste how is scientificlly and effectively reduced, realizes rainwater source emission reduction and control
System mitigates Urban Storm Flood disaster, improves the utilization rate of rainwater resource, the especially construction of Ecology civilization and sponge city,
One of the heavy difficult point faced as townscape garden management.
" low influence exploitation " is a kind of Ecology administrative skill, is advocated by utilizing some small-sized distributing ecologies in source
Treatment technology so that the hydrology-water quality characteristic after regionl development is preceding almost the same with exploitation, and the structure for passing through ecoscape is realized
The synchronous protection target of municipal lake water quality and quantity.Based on it is low influence exploitation rainwater Scatter Gather, under ooze with disposition key
Technology is the low research emphasis for influencing exploitation rainwater comprehensive utilization in city under the conditions of establishing urban development transition and southern climates.
Rainwater-collecting processing unit at this stage is all based on Green Roof mostly, and Green Roof is emerging city surface source
Groundwater pollution control, often by as Best Management Practices (Best Management Practices) use and low influence
The important component of development technique system.
Since the nineties, some domestic big cities start Accelerating The Construction Green Roof, however, the purpose promoted is often
Its landscape value, energy saving value etc. are biased toward, existing design specification is also only to roof bearing capacity, Plant choosing and construction
Technology etc. is described, and has ignored the pollution control emission reduction ability of Green Roof, also results in part rainwater waste, dry season
Green Roof input pours the problems such as expensive.
Currently, for the construction in sponge city, major measure be build include sunk type greenery patches, artificial swamp and
The Surface structures such as permeation pavement.And the research of the sponge measure in the skyscraper larger for accounting for urban size proportion, mesh
It is preceding still in blank.
Moreover, most of also rest on of the urban skyscraper rainwater engineering in China excludes rainwater by pipeline at this stage
Stage on, urban skyscraper Rainwater Resources are using lacking system research, unripe rainwater recycling system.
Chinese patent CN106284863A discloses a kind of construction method of skyscraper Green Roof, disclosed skill
In art scheme, according to roof structure base treatment, water storage drainage system structure, hypothallus and vegetable layer screening, roof load point
Analysis and hypothallus and vegetation layer building, are the structure and environmental quality according to FRAME ON THE ROOF OF HIGH-RISE BUILDING, a kind of reasonable design provided
Skyscraper Green Roof construction method, by the way that engineering waterproofing, roof greening and energy-saving heat-insulating triplicity are got up,
A rounded system is formed, there is a degree of mitigation to city " tropical island effect ", is conducive to increase urban atmosphere
In oxygen content, absorb harmful substance, mitigate atmosphere pollution, improve living environment, beautifying city landscape, realize people with from
Right gets along amiably and peacefully, and rationally solves Green Roof asking in roof load, Drainage Design, Plant choosing, soil configuration etc.
Topic.
However above-mentioned Green Roof structure be easy to cause surface layer vegetation water shortage death in dry season, increases management cost, does not have
It is systematic also not use solar energy, the wind energy of skyscraper roof in view of the reasonable of water conserves using with device,
And it is not particularly suited for rain of the processing containing more solid small particles suspended matter, micro metal ion, nutritive salt and organic matter
