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 planarized structure of the many employings of current artificial swamp both domestic and external, 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, limit the effect of wetland sewage disposal, add artificial swamp floor space.Mainly through ladder of cascades oxygenation, bottom, current artificial swamp aeration aerating arranges that aerated conduit and surface arrange the modes such as aerating apparatus and realize, these artificial swamp aerating apparatus running costs existing are high, complex structure, maintenance difficult, and mostly have impact on the landscape function of artificial swamp, destroy the visual enjoyment of people.
Sewage treatment plant tail water is disposed and is mainly contained three kinds of approach: one is process rear direct discharge up to standard, two is reuses after advanced treatment, and three is build tail water refining plant to process further tail water, reaches predetermined water quality standard, alleviate the water environment 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 eco hydraulics technology three class.Physical technique comprises diversion dilution and watercourse aeration, and diversion dilution introduces upstream by the regulation and control of hydro project exactly or neighbouring clean water source dilutes tail water, tail water is diluted at short notice, reaches certain water quality standard.Because the total amount of pollutant that can not reduce in tail water is diluted in diversion, therefore can only as a kind of supplementary means of tail water purification.Aeration in tail water, is 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, aerobic microbiological amount reproduction in tail water is impelled to consume the organism in water body fast, improve the detergent power to pollutent, improve water quality condition.In recent years, the biology based on artificial swamp---eco-treatment technology is promoted utilization rapidly with the technique of its maturation, cheap cost.Controlledly dosing is on 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, makes water resources again be utilized.Biological---the advantage of eco-treatment technology be invest lower, anti-impact force strong, simple to operate, combine the landscape design of necessity, can beautify the environment.But biological---ecological engineering also has some limitations, and is not suitable for that heavy metal content is higher, potential of hydrogen is too high and the tail water of biodegradability difference, and floor space needs to be explored further compared with the long-time running ability of Iarge-scale system and perfect etc.Eco hydraulics purification tail water to the effect that channel longitudinally on build bending and wriggle, torrent, unhurried current, pool, shoal interlock alternate general layout, and the method has concrete requirement to by water water body form, 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 dissolved oxygen concentration in the artificial wetland water body existing for prior art, the defects such as the dirty water decontamination handles effect is undesirable, the demand of further raising and increase view, the present invention utilizes the unique texture of tower, water body aeration and biopurification are organically combined, while effectively purifying waste water and increasing water quality, adds visual sense of beauty.
Technical solution of the present invention: landscape tower-shaped water body aeration and biological purification plant, is characterized in that pyramidal structure, comprises posticum, run-off, outlet canal, wherein the central authorities of run-off are posticums, and outlet canal communicates with posticum; The outer of described run-off is arranged with some one functional layer, biological ball purifying area, the aquatic floral region of view is comprised in each functional layer, 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, and the other end of hydraulic pipe installs water pump.
Advantage of the present invention: do not improve oxyty in sewage by means of only freely dropping, and add the function of biological reinforced process, significantly improves the processing efficiency of artificial swamp, the water quality of sewage effluents.Compared with some existing technology, tool has the following advantages:
1) water oxygenation efficiency is high, and the present invention utilizes pyramidal structure, between the layers free drop water aeration, makes the abundant oxygenation of water body, for the further treatment and purification of sewage creates favourable condition.
2) water body purification ability is comparatively strong, and sewage, under the effect of flow deflector, fully contacts with the biological ball in device, and the microorganism on biological ball to a certain degree eliminates the material such as organism, nitrogen, phosphorus in sewage in the process.
3) view aesthetic effect is good, and the present invention does not only destroy the landscape function of artificial swamp, but also adds the landscape effect of artificial swamp and Sewage Plant.
4) to water quality, water yield change strong adaptability, if influent quality pollution concentration is higher or effluent quality requires to improve the progression that can increase pyramidal structure, if the sewage water yield increases more, multiple device can be built with the form of parallel connection to meet water yield requirement.
5) structure is simple, construction cost is low, easy to maintenance.
