Description
Technical field
The present invention relates to the ecological floating island device of the field of purifying water body more particularly to a kind of purifying water body pollution of area source and
Its application method.
Background technique
Pollution of area source, also referred to as non-point pollution refer to that the pollutant of dissolution and solid from nonspecific place, in precipitation or melts
The souring of snow is descended, and imports receiving water body by runoff process comprising river, lake, reservoir and bay etc., and cause
Organic contamination, the pollution of water eutrophication or the other forms such as poisonous and harmful.
The characteristics of according to pollution of area source generation area and process, is generally classified as city surface source pollution and agricultural area source is dirty
Contaminate two major classes:
1. agricultural non-point source pollution refers in Agricultural Activities, silt, nutritive salt, pesticide and other pollutions in farmland
Object, during precipitation or irrigation, by agricultural surface runoff, interflow, agricultural drain and underground leakage, into water body and shape
At pollution of area source.These pollutants are mainly derived from farmland fertilization, pesticide, livestock and poultry and aquaculture and rural resident.
2. city surface source pollution refers under conditions of precipitation, rainwater and runoff wash away urban ground, and pollution runoff passes through
The transmission of drainage system makes receiving water body water pollution.
The control of pollution of area source can be divided into source control, migration control and " remittance " control three classes:
1. source controls: infiltrating, store and utilizing to reduce diameter in source region elimination pollutant accumulation mainly reinforcement rainwater
The generation of stream；
2. migration control: precipitation runoff is in migration since physics, chemistry and biological effect, water and water quality can occur
Variation；
Control 3. converging: when precipitation runoff reaches receiving water body, runoff and water body can meet in land inland water ecotone, sky here
Between and process be referred to as pollution of area source control process chain " remittance " node.Generally converged in bank, irrigation canals and ditches and the application of earth's surface junction
Control.In terms of the river basin pollution control of remittance control, this diatomite device technique is the main of mitigation city surface source pollution
One of technological means.
Floating island technique is using plant roots and stems as carrier, but since water plant is easy excessive multiplication and aging is dead earliest
Die, harvest and processing are not easy, there is the problem of many mankind are unable to control and factor, thus the technology fail to directly apply to compared with
In the improvement of large-scale eutrophic lake.
Organic polymer carrier: since the manufacture craft of high-molecular organic material is highly developed, thus in water purification works
In can be widely used, but the specific surface area of this carrier is small, is unfavorable for microorganism colonization, is easily damaged, become after discarded for
The persistent ailment of solid waste or even danger wastes, causes secondary environmental pollution, and the materials such as most common foamed plastics
Capacity of anti-storm is also poor, and intensity is low, therefore application is limited.
Inorganic carrier, due to its manufacture craft and higher cost, there is presently no being widely used, still in research rank
Section.But compared to organic carrier, the environmental benefit of inorganic material is higher and more valuable.At present common vermiculite, expanded perlite,
The inorganic material such as porous ceramics, float stone, biomass carbon are as host material.The specific gravity of vermiculite is small, and hole is more, is also well suited to micro-
Biological growth, but in water after the long period impregnates, part vermiculite can sink, and lose chinampa function.Expanded perlite is
A kind of lightweight, multifunctional novel shaped material, but its structural strength is too small, can hardly be used for sewage treatment.Porous ceramics density is small,
Porosity is high, and large specific surface area, absorption property is good, is very suitable to attached growth of microorganisms, theoretically, floating for making
Island carrier is feasible.But its complex manufacturing technology, cost is high, and therefore, it is difficult to can only be used as and refer to material by large-scale use
Material.Though float stone has the characteristics that light, hole is more, its internal porosity connectivity is very good, can be all after the long period impregnates
Sink, it must be with adhesive etc. with the use of chinampa carrier can be made.In addition, the price of float stone wants high compared with other materials
It is more；Although biomass carbon has the light porous, good characteristics such as absorption is strong, its is loosely organized, and intensity is not high, loss late
Greatly, it needs to be used cooperatively with binder.In addition, the production technology of biomass carbon is also immature at this stage, cost is higher, source
It is restricted, therefore also some are difficult in popularization and application, now only make reference material.
Existing ecological floating island technology and associated materials can effectively handle water body pollution of area source problem, but specific
In the environmental protection application such as environmental project and ecological engineering, there are still many insufficient and limitations.
Therefore, the existing technology needs to be improved and developed.
