Technical field
The present invention relates to urban green-making tree box technology field more particularly to a kind of rainwater purification tree case systems, particularly
It is a kind of conducive to arboreal growth and to be capable of the rainwater purification tree case system of purifying rainwater.
Background technique
Existing tree case mostly uses greatly concreting or van-type structure, the aperture on kerbstone, installs rainwater grid
Son, then cover reinforced concrete cover plate.The material of concrete is airtight, and the rainwater of storage can go bad, and has seriously affected rainwater water
Matter is unfavorable for arboreal growth and tree root respiration.Concrete material need to consume a large amount of rock or land resource, and pour
Inconvenience is built, transports and installs, it is costly.
Rainwater can directly be exhausted by inlet for stom water in existing tree case, cannot recycle rainwater resource.With urbanization
Development aggravation, a large amount of rainfall runoff are not pocessed the burden for direct emission being increased to municipal drainage facility, especially just
Phase rainwater is doped with a large amount of earth's surface pollutant, and flowing into river makes river water quality black, is smelly.
Largely studies have shown that rainfall runoff has apparent first flush to act on, i.e., in most cases, pollutant is concentrated
In several millimeters of rainfall in the early stage.Initial rainwater runoff has the characteristics that flow is big, impact is strong, pollutional load is high, carries out comprehensive
It closes to administer and has become important emerging project.Rainwater is in descent, dissolved gas in air, and dissolution or suspension are solid
Body, heavy metal and bacterium etc. can enter wherein, and the pollutant in rainwash washes away earth's surface mainly from rainfall, so ground
Table deposit is the main source of pollutant in rainwash.Surface sediments include many polluters, there is solid-state castoff
Clast, such as municipal refuse, animal wastes, Urban Building Construction place deposit；Chemicals, the chemical fertilizer agriculture applied such as lawn
Medicine, vehicle emission etc..Source difference with its deposit of the earth's surface of different land use functions, thus the water quality meeting of rainwater
Difference due to place, the difference of time.
