Description
Technical field
The present invention relates to a kind of ecological intercepting padding material and preparation method; Relate in particular to and a kind of the nitrogen and phosphorus pollutants that increases considerably due to the urban storm runoff is had interception function, can be used as combined type ecological intercepting padding material and the preparation method that lake, river shore protection plays the wave resistance fixation simultaneously again.
Background technology
Along with the expansion and the expanding economy in city, in recent ten years, the eutrophication process of urban rivers and lakes is quickened greatly, and at present, Chinese most cities river Lake Water Body has been in serious eutrophication state.The sink drainage in a lot of cities of China is the dirty interflow of a rain system; Whenever rainfall; The pollutent that is stranded in the road surface can cause concentration of nitrogen and phosphorus sharply rising at short notice in the water body with rainwater inflow stream Lake Water Body, and this is an one of the main reasons that causes this urban rivers and lakes water eutrophication to take place.
The urban rivers and lakes bank is connecting water body and land, is the ecosystem and the abundantest place of species diversity, is the important transitional zone that aquatic ecosystem and TERRESTRIAL ECOSYSTEMS are carried out material, energy, message exchange.Rationally build the urban rivers and lakes shore protection to increasing species diversity, system productivity in the urban water-body, prevent erosion, increase water quality and beautifying the environment significant.Existing river course slope protection technology has natural style bank protection, hard bank protection and environmental bank protection, cuts both ways.The natural style bank protection be plant growing with well developed root system on the ramp in river course, prevent erosion, satisfy the ecotope needs, have certain natural landscape effect.Its shortcoming is a poor stability, and surperficial earth is prone to by rain drop erosion.The main raw of hard bank protection mainly adopts and grouts or structure such as placed rockfill, onsite concrete, precast concrete block; It takes up an area of less, stability is high; But it is bigger for the river ecosystem negatively influencing; Hydrobiont and mikrobe with water purification function all are difficult to growth, and regular meeting reduces water body self-purification ability and causes water pollution.In addition, the hard bank protection can make to the domatic closing form of taking in river course that plant-animal and mikrobe all are difficult to the existence procreation in the water body, thereby causes the deterioration of water ecological environment.Environmental bulkhead tech has multiple mode; In rubble aggregate species phytyl, the solid soil species phytyl of geotechnological material, vegetation type eco-concrete, cement ecospecies phytyl and geotechnological material afforestation etc., they all can build a suitable environment for the plant-growth of river course slope protection like geotechnological material aggregate species phytyl, wire netting.
Yet, no matter be nature bank protection, hard bank protection or ecological revetment, all to lack special effective for repairing technological for big this phenomenon of nitrogen and phosphorus pollutants load variation range in short-term in the river Lake Water Body that typical storm runoff in the city is caused.Even be longer than natural style bank protection and the ecological type bank protection of safeguarding water quality; The former mainly relies on the assimilation of plant and removes the nitrogen phosphorus substance; Be difficult in a short time the pollution substance of high density is reached removal effect; The latter adopts microbe carriers such as rubble base, geotextile to reduce Pollutant levels in the water body through the method for biological contact, and too high or too low pollution load is lacked tolerance, and treatment effect can sharply descend when microorganism active was low in the winter time.Therefore; From current urban rivers and lakes bulkhead tech research and practice progress; Be badly in need of exploitation the nitrogen and phosphorus pollutants that increases considerably due to the urban storm runoff is had interception function, can be used as the combined type ecological intercepting padding material that lake, river shore protection plays the wave resistance fixation simultaneously again.
