Description
Technical field
The present invention relates to a kind of stair device that is used for the river water body restoration of the ecosystem, be mainly used in purification of water quality and the restoration of the ecosystem or the reconstruction of river water body, belong to environmental engineering and technical field.
Background technology
The river is the littoral resident source that supplies drinking water, and regulates the climate, and the landscape ecological and the Economic development in city played important effect.Yet along with the quickening of urbanization paces and the raising of industrialization degree, its mother river of depending on for existence has suffered serious day by day pollution.In section, 141 cities of China, have 63.8% section, city for the IV class to bad V class water quality, as the Suzhou River in Shanghai, the inland river in Ningbo, the outer fosse in Suzhou, the Qinhuaihe River in Nanjing, the Datonghe River in Changzhou or the like, water quality all is subjected to severe contamination, and black smelly phenomenon is very outstanding.
The biology of river water body (ecology) recovery technique is the emerging technology of a cleaning ambient getting up of new development, it utilizes absorption, conversion or the degraded of particular organisms to pollutent in the water body, reach and slow down or finally eliminate water pollution, recover the biological control measure of water ecology function, its final purpose is recovered exactly or is rebuild benign aquatic ecosystem.Compare with traditional physical chemistry recovery technique, it has the following advantages: (1) cost saving; (2) environmental influence is little; (3) can reduce Pollutant levels to greatest extent; (4) can be used for handling the place that conventional Pollution abatement technology is difficult to use.Use at present more have technology of biological membrane and biological floating bed technology etc.
Technology of biological membrane mainly utilizes the multiple microorganism that anchors at the film surface to remove organism, has the effect of denitrogenation dephosphorizing simultaneously, especially to being subjected to the more serious river of organism and ammonia and nitrogen pollution to have tangible decontamination effect improving.Biological floating bedly be applicable to that flow velocity is mild and be suitable for building the medium and small river course of floating bed, the plant of on floating bed, planting to the cleaning action in river mainly by following several approach: at first, the root district of waterplant provides apposition growth surface for microorganism and so as to carrying out the intermediary of vital movement, simultaneously because artificial bio-membrane's soil can guarantee the good condition that higher seepage velocity and microorganism exist, in biological soil, can form certain thickness microbial film usually, and contain great number of organic matters and microorganism, pollutent in absorption and the degradation of sewage is played an important role, make sewage can reach the high processing degree, this is the topmost effect of aquatic plant purification sewage in this system; Secondly, waterplant can be by absorbing and hazardous and noxious substances such as inorganic nutrient substances such as metabolism part nitrogen, phosphorus, the part small organic molecule that is decomposed out by microbiological oxidation and heavy metal, and finally they are removed from water body along with crop harvesting, it is introduced that waterplant can absorb 10%～20% nutritive substances such as phosphorus; At last; waterplant particularly vascular plant can absorb oxygen and be transported near the root district from atmosphere; cause root district aerobic environment on every side; keep near the normal activity of the microorganism in water root district; help the nitrated of organic degraded and ammonia nitrogen, unwanted bacteria and virus are because like a fish out of water and natural death.In addition, the branches and leaves in great numbers of waterplant are the irradiation that the water surface keeps the sun off, and have avoided because of the algae raised growth influences effluent quality, help the removal of SS and prevent the bed mud come-up.
The present invention is according to the river bed cross section both sides height of city river, middle low constructional feature and the requirement of purification of water quality and restoration of the ecosystem thereof, on the basis of existing biofilms technology and biological floating bed technology main device innovated and improved.
Summary of the invention
The object of the present invention is to provide a kind of purification efficiency height, running cost is lower, and secondary pollution is less, is convenient to manage and protect and regulate and control, and is applicable to the purification of water quality of river water body and the device of restoration of the ecosystem or reconstruction.
The stair device that is used for the river water body restoration of the ecosystem of the present invention is characterized in that comprising spud pile, wood frame, connecting rod, screw rod, nut, packing ring, adjustable plate, semisphere filler, sponge and plant.Mesh carrier that is woven into the bamboo chip of width 15-25mm of wood frame internal fixing wherein, the node place hangs the semisphere filler, utilizes the auxiliary plant of sponge to anchor in the semisphere filler; Connect with 2-3 root connecting rod between the wood frame, the connecting rod two ends are attached on the framework with hinge, and can rotate; The screw rod and the nut of each equidistant fixedly 3-5 belt washer of wood frame Parallel to the flow direction both sides; Adjustable plate contains 3-5 adjustment hole, is connected on the screw rod of adjacent wood frame.
The stair device that is used for the river water body restoration of the ecosystem of the present invention, it is characterized in that a plurality of continuous wood frame along the river the road section be step and distribute, help strengthening simultaneously the self-purification capacity of different depths water body, thereby shorten the time that aquatic ecosystem recovers or rebuilds.
The stair device that is used for the river water body restoration of the ecosystem of the present invention, it is characterized in that rationally to regulate according to river water body transparence and water quality condition the degree of depth of wood frame by adjustable plate, and select suitable plant, progressively formation comprises emergent, floatingleaved plant and submerged plant at interior stereo ecological repair system.
The stair device that is used for the river water body restoration of the ecosystem of the present invention is characterized in that the semisphere filler is a biofilm carrier, is again that root system of plant adheres to part, helps strengthening biological (ecology) repairing effect and prevents the plant lodging.
Unusual effect of the present invention is: (1) high-level efficiency.Compare with existing close refining plant, stair device can be simultaneously produces obvious cleaning action to the water quality of different water layers, and can adjust floristics and density according to practical situation, progressively form the three-dimensional arrangement of emergent+floatingleaved plant+submerged plant, this will effectively shorten the time of purification of water quality and ecological recovery; (2) easy-regulating.Easy for installation, dismounting easily only needs during adjusting the adjustment hole on four adjustable plates moved to can finish on the different screw rod of wood frame to rise or descend; (3) low cost.The starting material source that this device adopted is wide, and cheap; (4) pollution-free.This device is made all reusable or degradable of material that adopts, and yearly plant is doing further harmless processing after the harvesting then, to the environment non-secondary pollution.
