Description
Technical field
The present invention relates to the process field of ecological wastewater processing, and in particular to a kind of efficiently wetland returning aeration system and side
Method.
Background technology
Country advocates energy-saving and emission-reduction in recent years, is also being gradually reduced for the energy consumption needed for sewage disposal device operation, especially
In terms of it is town domestic sewage, from conventional AO, AAO technique to process changeovers such as artificial swamp, bacteria beds.
Artificial swamp is with the absorption of plant, the biofilm breakup organic substrates of plant root aerobic region formation, bacterium
Aerobic respiration and the absorption of bed course filler achieve the purpose that organics removal.Wherein plant accounts for main function with biomembrane, its
Influence factor is mainly illumination, humidity, oxygen concentration, temperature.
Research shows that high-temperature fine spray painting water can improve the photosynthetic rate of plant, improves Stoma of Leaves aperture index, and the later stage carries
High chlorophyll content in leaf blades and the plant later stage food value of leaf.Also fully prove that summer, more than 30 DEG C continuous high temperatures can suppress to plant around noon
The photosynthetic rate of thing, reduces the metabolism of plant, and prove immediate cause that photosynthetic rate reduces mainly due to strong light and
High temperature makes the excessive dehydration of crop cause plant wilt, plant stomata aperture is diminished caused.If plant physiology institute is supplied in time
The moisture needed, can make plant weaken or even eliminate wilting phenomenon, improve stomatal aperture, improve the growth and development shape under plant high temperature
Condition, makes the midday depression of photosynthesis phenomenon that the high undertemperature plants of strong light occurs at noon weaken or even disappear, due to photosynthetic area plus
Greatly, photosynthetic time lengthening, while the respiration consumption of plant is also reduced, therefore the metabolism of plant can be improved by a relatively large margin.
The present invention is the execute-in-place experience for many years of combining, to the Biological Contact Oxidation Process that is nowadays widely used
On the basis of improved, using high-temperature fine mist water-jet technology so that its power consumption compared to reduce nearly 70%, using returning aeration,
The aeration mode that temperature differential force aeration is combined.
The content of the invention
It is an object of the invention to provide a kind of efficiently wetland returning aeration system and method, Biological Contact Oxidation Process
On the basis of improved, it is real using high-temperature fine mist water-jet technology, returning aeration, the aeration mode that is combined of temperature differential force aeration
Now efficient wetland returning aeration system.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of efficiently wetland returning aeration system and method：Efficient wetland returning aeration system includes：System equipment is by two
Part forms, and top half and the latter half, top half are the ecosystem, sets on the ground；The latter half is aeration tank, point
Cloth is in underground.Efficient wetland returning aeration system composition includes：Top half includes：Sedimentation basin, decorates windmill plate, artificial swamp
Plant, rotation water distributing nozzle, Performance of Constructed Wetlands Substrates, inclined tube filler, fixed support, spiral stairway, ventilation window；Lower half subpackage
Include：Aeration tank, flow control valve, careless cage filler, filler support, undercurrent pump, pulls out air hose.
System is to sewage disposal process and method：Sewage enters the aeration tank equipped with careless cage filler after regulating reservoir
In, aeration tank bottom is pumped equipped with undercurrent, and undercurrent pump is by the sedimentation basin at the top of sewage lifting to system equipment, in lifting process
The pipeline used is equipped with two flow control valves, adjusts the two flow control valves, and making excessive sewage, spray arrives careless cage downwards
On filler.Because aeration tank build underground in for this, the relatively low outdoor temperature of summer subsurface temperature is higher, the high outdoor temp of winter subsurface temperature
Spend low, produce temperature difference by being arranged on the duct ventilation that pulls out of system surrounding, oxygen is dissolved into spray to careless cage filler after ventilation
Water in, the oxygen needed for electron donor is provided for aerobic bacteria aerobic respiration.Sewage is elevated to come up into sedimentation basin, precipitation
Inclined tube filler is placed with pond, a small amount of sludge of precipitation is flowed by gravity back in aeration tank, and it is anti-that denitrification is completed in aeration tank
Should, the ammonia nitrogen gone back in raw sewage is overflowed into nitrogen by pulling out air hose.System equipment is made of transparency glass plate, passes through fixed branch
Support is fixed with the spiral stairway among system equipment through row, ensures that monolithic stability is firm.
It is heavy determine to be equipped with downflow weir at the top of pond, it is sprayed onto first layer artificial swamp and wetland plant after supernatant spilling, first
The layer connection second layer.Using gravity installation spiral nozzle, first layer excessive moisture can be by spiral for first layer artificial swamp bottom
Nozzle carries out fine and smooth water distribution uniformity to understory and artificial swamp；Ventilation window is provided with the middle part of system equipment, first, strengthening bottom
The ventilation effect of portion's temperature difference, second, ensureing that temperature is unsuitable excessive (winter can close insulation) in summer system equipment, because of use
Full transparent glass makes, and can guarantee that the illumination of abundance carries out refinement water distribution uniformity on the premise of source of sewage ensures, can be greatly
The metabolism of plant is improved without influencing plant life.
The wetland plant of wherein described artificial swamp, wetland plant is thousand fiddleheads, thaliadeabata, Siberia are smeared；Plant
Kind density 20-40/m2, every kind of plant is according to 1:1 is planted.
Wherein described transparent glass can be quartz glass, silicate glass, soda-lime glass, fluoride glass wherein one
Kind.
Present invention has the advantages that：Efficiently wetland returning aeration system structure design of the invention is reasonable, and ecological, environmental protective, this is
System design Energy in use in treated sewage only has a small-power submersible sewage pump, is avoided using internal-external temperature difference add-back stream aerator
The waste of power, it is energy-efficient.And high temperature moisturizing greatly enhances the metabolism of plant, the processing of sewage is greatly improved
Assimilation effect, while also solve the problems, such as that winter plant is withered, even if because ensureing winter plant under conditions of temperature humidity
Also very high activity is had.It so can not only reach and save operating cost at the same time but also with beautiful and environment purification effect.
