Description
Technical field
The invention belongs to salt-soda soil water resource process fields, more particularly, to a kind of saline and alkaline region water containing seepage well and slight irrigation
Resource Collection utilization system.
Background technique
China's per capita water resource occupancy is only the 30% of world standard, most area water shortage or serious water shortage, in recent years
Come, increasing to the demand of water resource with the further in-depth of Development of China's Urbanization, how Efficient Development utilizes water resource
The challenge for needing to face jointly as the whole society.
In order to explore the sponge urban construction path under different natural environments, urban morphology, country has carried out two batches totally 30
A sponge city Pilot project construction, sponge urban construction at present is like a raging fire to be carried out in the whole nation, for various different underlays
It is emerged one after another using different rainwater-collecting purifications and the technology and product that utilize in face.Rainwater is a kind of fresh water being of great rarity
Resource, especially for beach saline land, this serious water shortage region collects and utilizes rainwater, that is even more estimable.It is saline and alkaline
Ground is because of water shortage, and salt concentration has exceeded the ability to bear of plant in soil, forms salt damage.Salt comes with water, and salt is gone with water,
So must assure that sufficient freshwater resources supply, saline and alkaline land resource can just accomplish sustainable use.
China's coastal saline-alkali soil gross area is up to 500 × 104hm2,.In these years with economy and industrial expansion, salt-soda soil
Area has become the fresh position of economic development, and in order to meet the needs of Development control area, " aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer
The method in salt-soda soil is widely used.The method that " the aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer salt-soda soil is by salt-soda soil
Soil improvement is good or after replacing with planting soil, aggregate chips is laid below planting soil, saline-alkali soil is isolated, prevent capillary water with high salt
Into good soil, then under aggregate chips layer, weeper drain is set, water that the capillary haline water that comes up of infiltration and good soil are arranged and
When be discharged in city planting ductwork.It is more than simultaneously drenching layer to prevent groundwater level, causes drenching layer to fail, greenery patches elevation is padded with the earthwork
Height, generally padded to be at least higher than 1.5 meters of level of ground water peak or more, haline water is remotely descended in realization, reduces underground with high salt
The influence of water can be afforested normally to guarantee to change good soil no longer by salination, transplant various plants.But it is existing
The method defect that " the aggregate chips drenching layer " having adds " hidden pipe salt discharge " to administer salt-soda soil is: after the rain penetration after rainfall enters soil,
It is lost through aggregate chips layer into saline and alkaline laminar flow, or has been directly discharged into municipal drainage pipe network, rainwater cannot be utilized effectively, while be applied fertilizer
Cheng Zhong, the nutriments such as a large amount of N P and K have also been discharged into municipal rain system therewith, have also caused the eutrophication of downstream water；
Have little time the rainwash rainwater of lower infiltration when rainfall, flow into the low gesture regions such as peripheral path, increases road drainage pressure and interior
Flooded risk, while greenery patches soil washes away road surface with runoff, stays the runoffs pollution problem such as mud after causing road rain；Afforest earth volume
Greatly, uneconomical.
Summary of the invention
