Abstract
The invention discloses a method for intercepting surface source of nitrogen and phosphorus by using an artificial floating island. The method comprises the following steps of (1) selecting proper shapes for floating island units according to a cross section of a river; (2) fixing the floating island units on fixing piles along the rivers with a mooring line; and (3) planting emergent aquatic plants and hygrophytes which have strong decontamination capability and landscape effects embeddedly on the floating island units. The method for intercepting surface source of nitrogen and phosphorus by using the artificial floating island is simple, has low cost, can effectively remove nutrient substance from a water body and improve transparency of the water body when the artificial floating island is used for an ecological interception project of the surface source of nitrogen and phosphorus loss, improves the ecological system of the water body, solves problems for recovering serious damages to ecology of rivers, lakes and marshes, ponds and the like, plays an important effect for ecological interception of the surface source of nitrogen and phosphorus loss, and broadens ecological interception method for the surface source of nitrogen and phosphorus loss.
Description
Technical field
The present invention relates to a kind of method with artificial floating island interception face source nitrogen phosphorus, artificial floating island is used for face source nitrogen and phosphorus loss ecological intercepting engineering.
Background technology
A major reason of at present water pollution enters water system by the agricultural area source nitrogen and phosphorus loss and causes, the agricultural area source nitrogen and phosphorus loss causes the water system eutrophication, the Water phosphorus content rolls up, cause hypertrophy and the breeding of aquatic organism and some algae, dissolved oxygen content descends in the water body thereby cause, and causes the mortality of hydrocoles and waterplant, and corrupt organism has aggravated again the pollution of water body, cause the water ecosystem havoc, affected improvement of the ecological environment.
In order to remove the water nutrition material; carry out ecological environmental protection and recovery; come into effect now source, opposite nitrogen and phosphorus loss ecological intercepting engineering; taked a large amount of method interceptions to enter the face source nitrogen phosphorus of water body; as set up agriculture wet land system; build ecological intercepting type canal pool system, to canal pool desilting mud, the modes such as planting plants.Quantities that these methods have drops into larger, and what have needs regular maintenance, cleaning, and the interception result that has is not obvious, and expends a large amount of manpower and materials.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method with artificial floating island interception face source nitrogen phosphorus, and method is simple, can effectively improve water ecosystem, and cost is low.
For solving the problems of the technologies described above, the invention provides a kind of method with artificial floating island interception face source nitrogen phosphorus, it is characterized in that, may further comprise the steps:
(1) selects suitable chinampa cell cube shape according to cross section of river;
(2) be fixed on the chinampa cell cube on the spud pile of river alongshore with hawser;
(3) emergent, the hygrophyte that the ability of depolluting is strong, have landscape effect planted in embedding on the cell cube of chinampa.
In the navigation district, do not comprise the shared water surface width of described chinampa cell cube, residue river water surface width satisfies the navigation requirement.
The beneficial effect that the present invention reaches:
The invention provides a kind of method with artificial floating island interception face source nitrogen phosphorus, method is simple, cost is low, artificial floating island is used for face source nitrogen and phosphorus loss ecological intercepting engineering, can effectively removes the water nutrition material, improve the transparency of water body, improved the ecosystem of water body, solved the ecological subject to severe risks of damage difficult problems such as recovery river, lakes and marhshes, pond, source, opposite nitrogen and phosphorus loss ecological intercepting has been brought into play great role, has widened the method for face source nitrogen and phosphorus loss ecological intercepting.
Embodiment
Below the invention will be further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Chinampa cell cube carrier adopts the plant vector of non-secondary pollution, can select different chinampa cell cube shapes according to the cross section of river situation, residue water surface width should satisfy the navigation requirement in the navigation district, the chinampa cell cube is fixed on the littoral spud pile with hawser, and the emergent that the ability of depolluting is strong, landscape effect is good, the hygrophytes such as Chinese celery, calamus are planted in embedding on the cell cube of chinampa.Little ecologic niche of the waterplant foundation network sample in the cell cube of chinampa has typical active biological film function, has the very strong ability that purifies water, and multiple pollutant is had very strong absorption, decomposition, accumulation ability.The chinampa cell cube is the bed of laying eggs that fish lay eggs, and also is the habitat of small fish, and the plant plankton in the water has become bait.Artificial floating island itself have cover, eddy current, feed texts, consisted of the good condition that fish are lived, improved the ecotope of water body.Waterplant on the chinampa can attract again insect and the birds such as honeybee, dragonfly Yan, butterfly, for they are nested, live and created condition.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
Claims (2)
1. with the method for artificial floating island interception face source nitrogen phosphorus, it is characterized in that, may further comprise the steps:
