Content belong to related content in the prior art, will be no longer developed in details in the present embodiment.
Suspension filter subsurface flow wetland system further includes suspension filter unit 4, as seen from Figure 1, in the present embodiment, is suspended
Filter element 4 extends to the inside of level-one wetland unit 1 along the longitudinal direction.Suspension filter unit 4 includes the filtering that front and back extends
Pond body, for filtering pond body relative to subsurface flow wetland unit integral sinking, filtering pond body includes spaced apart two pool walls 42 in left and right
And the bottom of pond 411 between two pool walls, the elevation on 42 top of pool wall are greater than the elevation on 5 top of packing layer.In two pool walls
Lateral arrangement has filter plate 41 between middle section, offered on filter plate 41 supply water across perforation, meanwhile, two pool walls 42 it
Between along the longitudinal direction arranged for interval have multiple crossbeams 44, filter plate 41 is divided into spaced apart along the longitudinal direction by multiple crossbeams 44
Multiple portions, each section are each attached between corresponding crossbeam.It can prevent monolithic filter plate from installing by way of adding crossbeam
Inconvenient situation occurs, while can be improved the safety in utilization of filter plate.The inside for filtering pond body is divided into top by filter plate 41
Filter after water retention zone 48 and underlying filtering area 49.
It being equipped on filter plate 41 multiple filters (unmarked in figure), filter is used to carry out back flush to suspended filter material,
The specific structure of filter is referred to shown in the application for a patent for invention that application publication number is CN103977611A.It is filled out in filtering area
Filled with suspended filter material 410, the density of suspended filter material 410 is less than the density of water, and after supplying water into filtering area, suspended filter material suspends
In filtering area, moreover, as water flow can gradually be collected in the lower section of filter plate and constantly be compacted, to flowing through between suspended filter material
The raw water in gap is filtered, and intercepts the suspended matter in raw water.
Suspension filter distributing channel 412 is offered in bottom of pond, the inside of suspension filter distributing channel 412 is formed and filtering area phase
The intake tunnel of connection, by Fig. 2, it can be seen that suspension filter distributing channel 412, which has, is extended to the over extension outside the body of filter tank
Inlet segment 46, the extension inlet segment 46 are located at the outside of filter plate and subsurface flow wetland unit.It is set respectively in the two sides for extending inlet segment
It is equipped with inlet channel 43, is separated between inlet channel 43 and extension inlet segment 46 by overflow weir 413, the water in inlet channel 43
When reaching setting value, the raw water in inlet channel is by the top overflow to extension inlet segment 46 of overflow weir.In the present embodiment, setting
Inlet channel simultaneously cooperates overflow weir, be based in actual use the case where depending on, wet land system when in use, raw water be usually by giving birth to
Living sewage, industrial wastewater even initial rainwater are constituted, and the flow velocity and flow of raw water are different, if directly by extension inlet segment
Raw water is received, the water flow fluctuation that will lead to after filtering area, filter in water retention zone is larger, and the water inlet in wetland unit is caused to be fluctuated too
Greatly, it is unfavorable for the filtering of wetland unit.In the present embodiment, it is equipped with cover board in the upper end for extending inlet segment, is fixed on the cover board
Water inlet pipe 45, the water inlet pipe are connected with suspension filter distributing channel.It certainly, in other embodiments, can be by water inlet pipe and lid
Plate removes, and opens wide the top for extending inlet segment, makes the direct overflow of the raw water in inlet channel into extension inlet segment.
By above-mentioned statement it is known that filtering pond body integral sinking arrangement, correspondence reduce suspension filter distributing channel
Elevation is not needed to raise raw water into (or reducing the height raised) again, be realized when raw water flows into suspension filter distributing channel
It automatically flows into and automatic fitration, does not need manual intervention, meanwhile, reduce the whole hydraulic losses and power consumption of wet land system.
Due to filtering pond body integral sinking, so that water retention zone 48 is corresponding in the horizontal direction with packing layer 5 after filter.The pool wall 42 in two sides
Wetland wall-through hole 47 is offered on the part of water retention zone after filter, water retention zone and undercurrent are wet after the connection filter of wetland wall-through hole 47
The packing layer of ground unit, the quantity of wetland wall-through hole is multiple and even laminating arranges that every layer includes edge along the vertical direction
The spaced apart multiple wetland wall-through holes of front-rear direction.In the present embodiment, wetland wall-through hole is the latus rectum extended in left-right direction
Flat hole, the sum of sectional area of all wetland wall-through holes should be identical as the filter effective cross sectional area being arranged on filter plate.Water after filter warp
Horizontal row is into packing layer after crossing latus rectum flat hole.When normal use, water after filter after filter in water retention zone through the wetland wall-through hole into
Enter in packing layer, when needing to clear up suspended filter material, the water flow in packing layer can be through the wetland wall-through hole reverse flow
After moving to filter in water retention zone.
In the utility model, pool wall separates water retention zone after filter and packing layer, and pool wall also constitutes subsurface flow wetland unit
A part of middle groove body, when specific design and molding, can by the groove body one of pool wall, bottom of pond and subsurface flow wetland unit at
Type.The utility model pre-processes the raw water entered in subsurface flow wetland unit by suspension filter unit, comparative experiments table
Bright, the simple subsurface flow wetland unit of group composition and division in a proportion of suspension filter unit and subsurface flow wetland unit is to COD(COD) and ammonia nitrogen
Removal be respectively increased about 12% and 25%, avoid COD(COD) and ammonia nitrogen it is excessively high and lead to subsurface flow wetland unit
The phenomenon that subsurface flow wetland unit silting, occurs caused by the substances such as interior algae are bred.
The specific embodiment 2 of the utility model suspension filter subsurface flow wetland system, as shown in Figure 5 to Figure 6, the present embodiment are suitable
