Abstract
The utility model discloses a radial flow artificial wetland, which comprises a water outflow canal (3), a plant wetland (2) and a water inflow canal (1) which are arranged around a sedimentation tank (4) from inside to outside in turn, wherein, the inside of the water inflow canal (1), i.e. the side contacting the plant wetland (2) is provided with a water permeable wall; the outer side of the water outflow canal (3), i.e. the side contacting the plant wetland (2) is also provided with a water permeable wall; therefore, the radial flow artificial wetland in which water is fed in from the periphery and is discharged from the center is formed. The utility model can prevent the accumulation of organics in substrate, wherein, plant fully absorbs the intercepted organics at first; therefore, because organic load is greatly reduced at the back end, hydraulic load of unit area is increased substantially to ensure evener distribution of the organic load inside the entire system and much slower accumulation of the organic load in the substrate. Therefore, the utility model solves the problem of blockage of ordinary artificial wetland and can prolong the service life of the artificial wetland.
Description
Technical field
The utility model relates to a kind of radial-flow artificial swamp that is used for waste water control.
Background technology
Handling sanitary sewage with artificial wet land system and intersect the technology of producing waste water, is the waste water control novel process that external immediate development is got up, and development rapidly, has greatly to replace the partly traditional secondary biochemical treatment and the development trend of advanced treatment.
But artificial swamp is as a kind of wastewater treatment new technology of inexpensive, widespread use fast and effectively, and its lasting operating capability is extremely important.But artificial swamp is in operation and occurs the matrix obstructing problem easily, resolves the application potential that this problem just can better have been given play to artificial swamp.There are some researches show that organic matter accumulation has the very high possibility that causes obstruction in the wetland matrix.Along with the obstruction gradually of matrix, the hydraulic conductivity of wetland also reduces, thereby influences flow path (for example promoting surface flow), finally also has influence on the treatment effect and the operation life of wetland.Simultaneously, the aeration status of matrix can have influence on the oxygen supply situation of matrix again, thereby has influence on the activity of aerobic microbiological, finally also influences the treatment effect of wetland.Address this problem at present measure be the method that adopts harvesting, but harvesting can not address this problem at all, and can only alleviate degree and proper extension work-ing life of obstruction, but along with the development of root system of plant and the increase of duration of service, blockage problem can occur once more.After the front end of water inlet stops up, can cause total system to intake, and then wetland can't be used.The basic reason of stopping up is that the organic loading of feed-water end is much higher than other parts, and solving the root problem that stops up is exactly to solve the organic loading of common artificial swamp and the contradiction of flow area.
Summary of the invention
Task of the present utility model provides a kind of radial-flow artificial swamp, to solve common artificial swamp blocking problem.
The technical scheme that its task that realizes the utility model adopts is: comprise wetland, settling tank, inlet channel and go out water channel, and with the settling tank is the center, be water channel, wetland, inlet channel outward successively, the side that a side that promptly contacts with the plant wetland in the inboard of inlet channel, the outside that goes out water channel promptly contact with the plant wetland is permeable wall, constitutes the radial-flow artificial swamp by periphery water inlet, central position water outlet thus.
Advantage of the present utility model is: pass through appropriate design, with the wetland construction peripheral water inlet of serving as reasons, the central position water outlet, increase the form of water inlet portion flow area greatly, therefore, plant can fully absorb the organism of interception, and reduce greatly owing to organic loading at back segment, the hydraulic load of unit surface can significantly increase, make organic loading more even in the distribution of total system, accumulation in matrix also slows down greatly, and the blocking problem of common artificial swamp just obtains understanding and determines, thereby has prolonged the work-ing life of artificial swamp greatly.
Description of drawings
Fig. 1 is a radial-flow artificial swamp vertical view.
Fig. 2 is the enlarged diagram of the longitudinal cross-section of Fig. 1.
Embodiment
The utility model is a kind ofly can overcome the artificial swamp type that organism accumulates in matrix, it is by water inlet portion, the plant wet land system, the water part is formed, to be sewage enter from the periphery of wetland its feature, increases the hydraulic load of unit surface gradually along with the decline of organic loading, converges to the central place at last and concentrate water outlet, it can be adjusted design accordingly according to sewage quality, the discharge of sewage, to reach treatment effect the most efficiently.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
As shown in Figure 1: comprise plant wetland 2, settling tank 4, also comprise inlet channel 1 and go out water channel 3, and with settling tank 4 is the center, be water channel 3, plant wetland 2, inlet channel 1 outward successively, a side that promptly contacts with plant wetland 2 in the inboard of inlet channel 1 is a permeable wall 5, a side that promptly contacts with plant wetland 2 in the outside that goes out water channel 3 is permeable wall (a not label), constitutes the radial-flow artificial swamp by periphery water inlet, central position water outlet thus.
Describedly go out water channel 3, its flow velocity can make organic loading being more evenly distributed in wetland like this greater than the flow velocity of inlet channel 1.
Described plant wetland 2 tilts to settling tank 4 directions, and its gradient is 0.5～10 degree, and the diameter ratio of its width and settling tank 4 is 2～10: 1.This plant wetland 2 may be partitioned into some, for example is made up of two or more than two little wetland, so that current are more even.Plant wetland 2, its peripheral shape can be designed to circle, Polygons or ellipse; Also can be designed as square, or Polygons; Can also be designed to other shape according to practical situation.
The longitudinal cross-section of above-mentioned plant wetland 2 is as shown in Figure 2: soil layer 12 down is sand bed 11 and pebble bed 6 last.
Sketch the working process that the utility model is disposed of sewage below in conjunction with accompanying drawing:
Sewage enters plant wetland 2 from inlet channel 1 by permeable wall 5, and after this pollutent in the water is tackled by the plant wetland and by the plant absorbing on the wetland, and the water and the water after the infiltration of soil layer 12, sand bed 11 and pebble bed 6 of a part continue to move ahead; Because the water inlet area is very big, the plant wetland can not stop up.The permeable wall of the current that move ahead through going out water channel 3 flows into out in the water channel 3, go out the water table ratio settling tank 4 peripheral pool wall height of water channel, so settling tank 4 gone in the water overflow.Settling tank 4 centers also are provided with baffle plate 10, make water flow into the bottom again after the inflow of upper end, flow out from upper end rising pipe 7 at last; And mud falls into shore pipe 8 in the water, is taken away by sludge pump 9 again.
