Description
Technical field
What the present invention relates to is a kind of landscape tower-shaped water body aeration and biological purification plant and purifying method, belongs to the dirty water decontamination handles technical field.
Background technology
Artificial swamp has that investment is low, power consumption less, the feature such as buffer capacity is large, technique is simple, at home and abroad be widely used, but because the biological processes such as the absorption of plant adsorption process Zhong Gen district and microbiological deterioration all need dissolved oxygen, and the current artificial swamp both domestic and external planarized structures that adopt more, sewage residence time in wetland is long, current are comparatively mild, root system of plant and filler long period of soaking be in water, cause artificial swamp matrix dissolved oxygen level low, the effect that has limited wetland sewage disposal, has increased artificial swamp floor space.Artificial swamp aeration aerating mainly arranges that by ladder of cascades oxygenation, bottom aerated conduit and surface arrange the modes such as aerating apparatus and realize at present, existing these artificial swamp aerating apparatus running costs are high, complex structure, maintenance difficult, and mostly affect the landscape function of artificial swamp, destroyed people's visual enjoyment.
Sewage treatment plant tail water is disposed the three kinds of approach that mainly contain: the one, process rear direct discharge up to standard, the 2nd, reuse after advanced treatment, the 3rd, build tail water refining plant tail water is further processed, reach predetermined water quality standard, alleviate the water surrounding pressure to entering water body, and reuse in addition by all kinds of means.Tail water purification techniques is mainly divided into physical technique, biology---ecotechnology and ecological water engineering technology three classes.Physical technique comprises diversion dilution and watercourse aeration, and diversion dilution is exactly by regulation and control introducing upstream or near the clean water source of hydro project, tail water to be diluted, and tail water is diluted at short notice, reaches certain water quality standard.Because diversion dilution can not reduce the total amount of pollutant in tail water, therefore can only serve as a kind of supplementary means that tail water purifies.Aeration is in tail water, to be filled with air (or oxygen) artificially, air is contacted strongly with tail water, oxygen is dissolved in tail water, accelerate the reoxygenation process of tail water, impel aerobic microbiological amount reproduction in tail water to consume fast the organism in water body, improve the detergent power to pollutent, improve water quality condition.In recent years, take artificial swamp as main biology---Ecological Disposal technology is promoted rapidly utilization with its ripe technique, cheap cost.Controlledly dosing is to soil by sewage treatment plant tail water for these class methods, and by physics, chemistry and bioprocess in soil, plant, water system, purifying contaminated thing, is utilized water resources again.Biological---the advantage of Ecological Disposal technology be invest lower, anti-impact force is strong, simple to operate, in conjunction with necessary landscape design, can beautify the environment.But biological---ecological engineering also has some limitations, and is not suitable for the tail water that heavy metal content is higher, potential of hydrogen is too high and biodegradability is poor, and the long-time running ability of the larger system of floor space needs further to be explored and perfect etc.Ecological water engineering purifies to the effect that building bending and wriggle on longitudinally at channel of tail water, torrent, unhurried current, pool, the staggered alternate general layout in shoal, and the method is to being subject to water water body form to have concrete requirement, and use range has limitation.
Summary of the invention
What the present invention proposed is a kind of landscape tower-shaped water body aeration and biological purification plant and purifying method, it is low that its object is intended to overcome in the existing artificial wetland water body of prior art dissolved oxygen concentration, the defects such as the dirty water decontamination handles effect is undesirable, further improve and increase the demand of view, the present invention utilizes the unique texture of tower, water body aeration and biopurification are organically combined, in effectively purifying waste water and increasing water quality, increased visual sense of beauty.
Technical solution of the present invention: landscape tower-shaped water body aeration and biological purification plant, it is characterized in that pyramidal structure, comprise posticum, run-off, outlet canal, wherein the central authorities of run-off are posticums, outlet canal communicates with posticum; Described run-off outer is arranged with some one functional layer, in each functional layer, comprise biological ball purifying area, the aquatic floral region of view, wherein the aquatic floral region of view is located at the periphery of biological ball purifying area, and one end of run-off connects hydraulic pipe, on the other end of hydraulic pipe, water pump is installed.
Advantage of the present invention: not only improved oxyty in sewage by freely dropping, and increased the function of biological reinforced processing, obviously improved the processing efficiency of artificial swamp, the water quality of sewage effluents.Compared with existing some technology, tool has the following advantages:
1) water oxygenation efficiency is high, and the present invention utilizes pyramidal structure, and free drop water aeration between the layers makes the abundant oxygenation of water body, for the further treatment and purification of sewage has been created favourable condition.
2) water body purification ability is stronger, and sewage, under the effect of flow deflector, fully contacts with the biological ball in device, and the microorganism on biological ball has to a certain degree been removed the materials such as the organism in sewage, nitrogen, phosphorus in this process.
3) view aesthetic effect is good, and the present invention does not only destroy the landscape function of artificial swamp, but also has increased the landscape effect of artificial swamp and Sewage Plant.
4) water quality, the water yield are changed to strong adaptability, if influent quality pollution concentration is higher or effluent quality requires to improve the progression that can increase pyramidal structure, more if the sewage water yield increases, can build multiple devices and meet water yield requirement with form in parallel.
5) simple in structure, construction cost is low, easy to maintenance.
