Description
Technical field
What the present invention relates to is a kind of biological floating bed with aerating apparatus being applicable to high flow velocities heavily contaminated river course, belongs to purification river water body polluting device technical field.
Background technology
Along with the increase of population and developing rapidly of urban construction, the sanitary sewage in a large number containing nutritive substance and trade effluent enter river course, pollute urban river water environment, destroy river channel ecology system.Ecological reestablishment gains great popularity in river water body Pollution abatement, wherein biological floating bed as a kind of novel eutrophication water recovery technique, take restoration of the ecosystem as fundamental principle, based on cultivation technique without soil, take macromolecular material as carrier, adopt Modern Agriculture technology, reached the artificial ecosystem reducing water pollution by symbiotic relationship between species, there is the advantages such as workable, running cost is low, easy care, ecological risk are little, landscape effect is good, be used widely.
Biological floating bed technology development, its cardinal principle uses emergent, submerged plant and artificial dielectric, effectively improves floating bed device to nitrogen phosphorus in eutrophication water and other organic removals.Affect the many factors of biological floating bed purifying water effect, except floating bed profile (have square, circular etc.), floating bed plant kind (having emergent, floating plant etc.) and floating bed internal structure etc., also there is certain impact to floating bed technique decontamination effect improving in the flow velocity of river water body and pollution level.
For flow velocity faster river course, river water body flow velocity is very fast, not only may produce bed system and destroy, the root system of floating bed plant is made to be not easy to fix, the biofilm detachment on root surface, also can shorten hydraulic detention time, thus causes treatment effect to decline.Application number is utilize the comprehensive enclosure of waterproof cloth in the Chinese patent " aquatic ecology reconstruction method in estuary region " of 200410041089.2, from the water surface to lakebed, fix with timber and ratchel, play wave resistance effect and stop a large amount of intrusions of extraneous lake water, but the situation of wave resistance effect when not considering that waterproof cloth destroys, will be affected.
For heavily contaminated river course, heavily contaminated river water body dissolved oxygen is often not enough, and floating bed plant growth is bad, and its root system is limited in one's ability to the noxious substance such as nitrogen, phosphorus.In order to improve Nitrogen/Phosphorus Removal, some scholars introduce biological floating bed technique miniature aerating apparatus, arrange underwater aeration machine and aeration head under floating bed, are formed reinforced biological floating bed.There are the patent and the pertinent literature report that are effectively improved biological floating bed technique decontamination effect improving by aeration effect both at home and abroad respectively, the Chinese patent " a kind of ecological floating bed device being convenient to keep away flood and aeration " being 201010250498.9 as application number controls motor rotating forward, stopping, reversion work by distance type positive and negative rotating controller for motor, thus the oblique leaf oar on control watercart rotates, but control device needs power consumption, adds biological floating bed process operation cost; In addition, as the aeration mode that the application number Chinese patent " wind-power sewage automatic aeration device and method " that is 200910013837.9 take wind-force as power, greatly reduce the energy consumption of sewage treatment process, meet country's " energy-saving and emission-reduction " requirement, but the rotation of fan blade affects by local climate in this aerating apparatus, if aeration effect can be affected under long-time calm condition, and similar energy-saving and aerating device with biological floating bed be combined then less.Not only to reduce large-flow rate water body to the destruction of bed system reduce floating bed process energy consumption to reach, make the better effect of water body purification ability of biological floating bed technique, be necessary constructively to innovate biological floating bed technique.
Summary of the invention
What the present invention proposed is that a kind of high flow velocities heavily contaminated river course that is applicable to possesses the biological floating bed of autonomous aeration performance, be intended to overcome the above-mentioned biological floating bed defect mentioned, solve the biological floating bed technical barrier at heavily contaminated river course dissolved oxygen deficiency, root system of plant limited sorption capacity.By being the mechanical energy of aerating apparatus compared with the kinetic transformation of large-flow rate water body, for river water oxygenation around biological floating bed system and floating bed, the destruction of current to bed system is slowed down in the external cloth hole of bed, the hydraulic detention time of water body in floating bed bed body can be increased simultaneously, strengthen biological floating bed decontamination effect improving.In addition, in floating bed bed body, cultivate hydrocoles, by hydrocoles, the filter of planktonic algae in water body is eaten, strengthen biological floating bed water purification function further.
Technical solution of the present invention: a kind of high flow velocities heavily contaminated river course that is applicable to possesses the biological floating bed of autonomous aeration performance, it is characterized in that: comprise cylindric floating bed bed body, bed body matrix, waterplant, hydrocoles, aerating apparatus and stationary installation, wherein water plant planting is in bed body matrix, hydrocoles cultivation is in circular floating bed bed body, cylindric floating bed bed body is fixedly connected with aerating apparatus, cylindric floating bed bed body is that two concentric drums are assembled by pvc pipe, aerating apparatus symmetry is arranged on around circular floating bed bed body, cylindric floating bed bed body is connected with stationary installation.
Advantage of the present invention:
1) in the heavily contaminated river course with larger flow velocity, floating bed of the present invention is adopted, the dissolved oxygen of biological floating bed system itself and surrounding water can be improved, floating bed plant is grown preferably, solves the biological floating bed deficiency affecting detergent power in heavily contaminated river course because dissolved oxygen is not enough;
2) the external cloth Porous materials of bed, reaches and slows down compared with the destruction of mass-flow to bed system, increase the service life, and increases the hydraulic detention time of water body through floating bed simultaneously;
3) between the concentric(al) circles band of column, filter-feeding fish is cultivated, not only increase the species diversity of water body, be conducive to the balance of water ecosystem, alleviate the burden of root system of plant absorption absorbed nitrogen, phosphorus and other objectionable impuritiess, this and fish easily fish for results, have certain economic worth;
4) in the present invention, the kinetic transformation of aerating apparatus utilization current is the mechanical energy of oblique leaf oar, does not need other energy consumptions, and structure is simple, is easy to manufacture.
