Description

A kind of ecological purification forces undercurrent overflow mechanism

Technical field

It the utility model is related to a kind of overflow mechanism applied at current wetland gap.

Background technology

Artificial swamp is the environmental treatment technology of a kind of water pollution control and aquatic ecological restoration, utilizes the ecology of animals and plants Characteristic, plays the purpose of purifying water body.Artificial swamp divides the cleanup forms such as surface stream, undercurrent, vertical current.In subsurface flow wetland system In, water body is in wetland bed internal flow, biomembrane, abundant root system, the topsoil on the one hand making full use of filler surface to grow Act on filler etc., to improve the effect of its treated sewage and ability, on the other hand since current flow below earth's surface, have Good heat insulating, treatment effect climate influence the advantages of small, sanitary condition is preferable.In Artificial subsurface flow wetland builds practice, Control current wetland water (flow) direction is to ensure to realize the key of complete undercurrent, and in currently used construction technology, current wetland goes out The form of pipeline is arranged at the mouth of a river using nature spilling water or in hypothallus mostly.Using nature spilling water form, easily lead to surface low and Undercurrent mixedly appears, and flow cavitation result is poor, can not realize the complete undercurrent of water body, reduces current wetland purification efficiency, and cloth Pipe method is put, expenditure of construction is higher, is easy to block in operational process, it is difficult to which dredging cleaning, adds later maintenance cost.

Utility model content

The utility model utilizes current wetland adjacent spot for the technological deficiency of water (flow) direction in existing control current wetland Block height difference, there is provided a kind of ecological purification being arranged at drop mouth forces undercurrent overflow mechanism, in current operational process, utilizes Law of connected vessels forces flow path elder generation level stream upward vertical current again, so as to achieve the purpose that to control water (flow) direction.

To achieve the above object, the utility model includes following technical solution：

A kind of ecological purification forces undercurrent overflow mechanism, including first baffle 1, second baffle 2 and gabion 3；

First baffle 1 and second baffle 2 are fixed on the drop of adjacent two plot wetland of the current wetland with drop vertically At mouthful；

First baffle 1 is arranged on the outside of planting soil layer 11 at high-rise current wetland drop mouth, its upper limb is higher than the high level 11 surface of current wetland planting soil layer, its lower edge are not higher than 11 bottom of planting soil layer；

First baffle 1 is gabion 3 below, which is located at the coarse sand filter layer 13 and rubble filter layer of high-rise current wetland 14 outsides；The lower section of gabion 3 is the brick wall 6 for isolating adjacent two pieces of current wetlands；

For second baffle 2 close to low layer current wetland side, its upper limb is equal with high-rise 11 surfaces of current wetland planting soil layer, Its lower edge is fixed on the brick wall 6 of the lower section of gabion 3；

There is gap, which is overflow port 4 between first baffle and second baffle.

Ecological purification as described above forces undercurrent overflow mechanism, it is preferable that the gabion 3 for stone built in gabion box and Zeolite filler, stone and zeolite filler outsourcing non-woven fabrics.

Ecological purification as described above forces undercurrent overflow mechanism, it is preferable that the current wetland is from top to bottom followed successively by Planting soil layer, nonwoven layer, coarse sand filter layer, rubble filter layer, clay lenses and rammed earth layer.

Ecological purification as described above forces undercurrent overflow mechanism, it is preferable that the outside of second baffle 2 and low layer undercurrent Cobble area 5 is laid between wetland planting soil layer 21, water draining plate 8 is set between cobble area 5 and low layer current wetland planting soil layer 21.

The beneficial effects of the utility model are, by first baffle, second baffle between high-rise and low layer current wetland And gabion constitutes a linker, it is ensured that current wetland current are after high-rise current wetland metalling bottom horizontal flow sheet through gabion edge The upward perpendicular flow of overflow port.Due to the stop of first baffle, surface low switchs to undercurrent completely, improves the purification effect of current wetland Rate.Gabion drainage mouth outsourcing non-woven fabrics in overflow device lower part, extends overflow device maintenance period, while the device is easily disassembled, Beneficial to the maintenance in later stage.

Embodiment

Embodiment 1

As depicted in figs. 1 and 2, current wetland is from top to bottom followed successively by planting soil layer, nonwoven layer, coarse sand filter layer, broken Stone filter layer, clay lenses and rammed earth layer.Ecological purification forces undercurrent overflow mechanism to include first baffle 1, second gear Plate 2 and gabion 3.

First baffle 1 and second baffle 2 are fixed on the drop of adjacent two plot wetland of the current wetland with drop vertically At mouthful.

First baffle 1 is arranged on the outside of planting soil layer 11 at high-rise current wetland drop mouth, its upper limb is higher than the high level 11 surface of current wetland planting soil layer, its lower edge are not higher than 11 bottom of planting soil layer.

First baffle 1 is below gabion 3, and gabion 3 is stone and zeolite filler built in gabion box, outside stone and zeolite filler Bag non-woven fabrics.Gabion is located at coarse sand filter layer 13 and the outside of rubble filter layer 14 of high-rise current wetland；The lower section of gabion 3 is isolation The brick wall 6 of adjacent two pieces of current wetlands.

For second baffle 2 close to low layer current wetland side, its upper limb is equal with high-rise 11 surfaces of current wetland planting soil layer, Its lower edge is fixed on the brick wall 6 of the lower section of gabion 3.It is laid between the outside of second baffle 2 and low layer current wetland planting soil layer 21 Cobble area 5, sets water draining plate 8 between cobble area 5 and low layer current wetland planting soil layer 21.

There is gap, which is overflow port 4 between first baffle and second baffle.Between high-rise and low layer current wetland One linker is constituted by first baffle, second baffle and gabion, it is ensured that current wetland current are in high-rise current wetland rubble Through gabion along 4 upward perpendicular flow of overflow port after 14 bottom horizontal flow sheet of layer.Due to the stop of first baffle, surface low switchs to dive completely Stream, improves the purification efficiency of current wetland.Water (flow) direction is as shown in Figure 3.

Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and Modification, therefore all equivalent technical solutions fall within the category of the utility model, the scope of patent protection of the utility model should It is defined by the claims.
