Description
Technical field
The utility model relates to environmental technology fields, are specifically related to a kind of saline alkali land drainage storage based on sponge city
It stays, purify and cyclic utilization system.
Background technique
Salt-soda soil is a type of salt aggregation, refers to that salinity contained by soil the inside influences the normal life of crop
Long, according to UNESCO and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.5438 hundred million hectares,
Wherein China is 99,130,000 hectares.The formation of China's alkaline earth and alkali-affected soil, it is most of with Carbonates In Soil add up it is related,
Thus basicity is generally higher, and serious salt affected soil regional plant can hardly survive.The saline and alkaline harm to plant is shown
The following aspects: 1, cause the physiological drought of plant;2, plant tissue is injured;3, plant normal nutrition is influenced;4, it influences to plant
The stomata of object is closed.Salt-soda soil salt discharge drop alkali planting method be primarily referred to as by pipeline arrange drop, physical isolation, organic fertilizer reconcile, it is resistance to
The methods of Soiline-alkali plants collocation, improves soil texture, plants green plants.So will salinity to salt-soda soil and supervision change
Good, to adapt to the growth needs of crops, existing salt discharging pipe distribution is more scattered, lacks the management of system, and salt discharge effect
Bad, water cannot recycle, so water resource waste is serious.
Sponge city is new generation of city storm water man- agement concept, and it is suitable well to refer to that city can have water as sponge
Should be able to power be " elasticity ", environmental change and natural calamity can be better adapted to.Can absorb water, seep water when rainy, water storage,
Water purification is catchmented, and the water release of storage is used when needing.It is currently applied to sponge urban construction device facility, is mostly
The midget plant of urban inner residential area is concentrated on, such as permeable road, stored water roof, water storage garden etc. are still, wide for being related to
The device facility that big plantation the soil especially rainwater in salt-soda soil and irrigation water accumulation and purification recycle is seldom.Meanwhile in recent years
Come sunk type greenery patches, permeable road etc. to quickly grow, application is still very narrow, and filler is more single, although infiltration ability compared with
By force, it but is difficult to purify rainwater, the rainwater of institute's accumulation is often only by the primary filtration in soil, filler, water body
It is still the initial rainwater of pollution, the recycling of water body is caused to be restricted, flows into river, lake will also result in eutrophication dirt
Dye.
Chinese patent application CN106592732A discloses saline alkali land drainage accumulation, purification and circulation based on sponge city
Using system, still, the system mainly by the accumulation of salt-soda soil rainfall, purification, using bringing entire sponge city into
Water circulation.Without considering that salt-soda soil rainfall is utilized by original place after accumulation, the pressure of pipe network is thus caused to become larger.
Utility model content
The purpose of this utility model is to provide a kind of saline alkali land drainage accumulation based on sponge city, purification and circulation benefits
With system, is utilized by salt-soda soil rainfall by original place after accumulation, greatly reduce the pressure of pipe network.In order to realize this reality
With novel purpose, it is proposed to adopt the following technical solutions:
The utility model relates in one aspect to a kind of saline alkali land drainage accumulation based on sponge city, purifies and recycle
