Described Winter protection device, wherein, water distributor is water distribution uniformity, receives filler place, the corresponding stage casing of water pipe and is provided with receipts water hole.
Described Winter protection device, wherein, the strong emergent of upper strata plantation soil removability of artificial swamp.
Variable flow wetland can be according to the concrete temperature Change in the external world by the adjusting of water distribution pipe, carry out the mutual conversion of horizontal-flow wetland and vertical-flow wetland, overcome the horizontal-flow wetland dissolved oxygen of intaking summer low, the shortcoming that vertical-flow wetland thermosteresis in winter is many, winter can flexible wetland operation scheme, thereby reduce the impact of temperature on wetland by forming ice sheet gas cloud thermal insulation layer, ensured that cold condition constructed wetlands can move continually and steadily.Variable flow wetland is by the mutual conversion of vertical current and horizontal flow, and the advantages such as the current scour matrix of different directions and decomposing organic matter efficiency height, can slow down and even overcome blockage problem.The present invention can be widely used in the Winter protection of large, medium and small artificial swamp, has the features such as pollution-free, simple to operate, reduced investment, working cost are low, high insulating effect, processing power is strong, operating performance is stable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
In artificial swamp of the present invention, be vertically filled with three sections of fillers, filler of the present invention is the combination of zeolite, gravel, Wingdale, slag, gac etc. and various different fillers, and the present embodiment is to describe as an example of limestone filler example.The particle diameter of the two sections of limestone fillers in left and right is 16-32mm, and the particle diameter of stage casing limestone filler is 8-16mm; The height of limestone filler is 1.6-1.8m, and bed height is 2.2-2.5m; In wetland, be evenly arranged ventpipe; The one end on limestone filler upper strata is respectively connected a water inlet pipe and water distributor with limestone filler top; An each rising pipe and the receipts water pipe of connecting of the other end of bottom; One water intaking valve is respectively set between water inlet pipe and water distributor and water head tank; Rising pipe and receipts water pipe are respectively provided with a main control valve and three sub-control valves, and three sub-control valves are wherein in different heights.
When artificial swamp is vertical downstream, the water distributor at limestone filler top connects the water intaking valve of water head tank and receives the main control valve unlatching of water pipe, and the water intaking valve of water inlet pipe and the main control valve of rising pipe are closed;
When artificial swamp is horizontal flow, the water intaking valve of water inlet pipe and the main control valve of rising pipe are opened, and the main control valve of the water intaking valve of water distributor and receipts water pipe is closed.
Be described in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, is concrete structure schematic diagram of the present invention.
It should be noted that, it is left and right, upper and lower that the present invention mentions etc., is to be all outward as the criterion with direction shown in Fig. 1 apart from specified otherwise.
High-order inlet flume 1 respectively by upper strata water inlet pipe 2 and limestone filler top water distributor 15 by the sewage of wish processing in artificial swamp.
In artificial swamp, be vertically filled with the limestone filler of different-grain diameter, by artificial swamp inside be divided into left section 4, stage casing 5 and right section 6.Particularly, the particle diameter of the limestone filler of left section 4 and right section 6 is 16-32mm, and the particle diameter of the limestone filler in stage casing 5 is 8-16mm.
In a specific embodiment, in artificial swamp, packed height is 1.6-1.8m, and bed height is 2.2-2.5m.Artificial swamp has a water inlet pipe 2 and 15, one rising pipes 7 of a water distributor and one and receives water pipe 16, respectively by separately into and out of water valve control Inlet and outlet water.Particularly, in a side of artificial swamp, between the waste pipe 13 of high-order inlet flume 1 and left section 4, be connected water inlet pipe 2 by water intaking valve 3, waste pipe 13 is also connected with water distributor 15 by water intaking valve 14.Water distributor 15 of the present invention is water distribution uniformities, receives on water pipe 6 and is only provided with at filler 5 places, corresponding stage casing and receives water hole.
At the opposite side of artificial swamp, the bottom of right section 6 is provided with rising pipe 9, and main control valve 7 and sub-control valve 8,10,11 are installed on rising pipe 9.The bottom of artificial swamp is provided with receives water pipe 16, receives on water pipe 16 main control valve 17 and sub-control valve 18,19,20 are installed.In sub-control valve 8,10,11 (18,19,20), the height location of the highest sub-control valve 10 (19) will be higher than the bed height of artificial swamp, minimum sub-control valve 8 (18) is the bottom in artificial swamp, and middle sub-control valve 11 (20) is the medium position in limestone filler.With packed height 1.6-1.8m in artificial swamp, bed height 2.2-2.5m is example, and sub-control valve designs respectively in distance bed body bottom 2.4m (sub-control valve 10,19), 1.3m (sub-control valve 11,20), 0.1m (sub-control valve 8,18) position to regulate the water level of wetland unit.
Operation when the present invention moves is in the winter time:
When artificial swamp is vertical downstream wetland, master control valve 7 on water intaking valve 3 and rising pipe 9 is closed, water intaking valve 14 is opened, start water inlet by waste pipe 13 by water distributor 15, simultaneously, master control valve 17 and the sub-control valve 19 received on water pipe 6 are opened, make raise of stage to 2.4m, after upper strata water level freezes (general control is 0.4-0.6m at ice layer thickness), by receiving water pipe 16 water outlets, valve-off 19, Open valve 18, reduce rapidly water level, in the time that wetland operating water level drops to 2.0m, valve-off 18, open flowing water Valve 20, discharge water to operating water level, on this water level, form the thermal insulation layer of ice sheet 21 and gas cloud 22, now top ventpipe 12 is opened, ensure the dissolved oxygen concentration of subglacial.
When artificial swamp is horizontal flow, close water intaking valve 14 and receive the master control valve 17 on water pipe 6, open master control valve 7 and sub-control valve 10 on water intaking valve 3 and rising pipe 9, start water inlet by water inlet pipe 2, make raise of stage to 2.4m, after upper strata water level freezes (general control is 0.4-0.6m at ice layer thickness), by rising pipe 9 water outlets, valve-off 10, Open valve 8, reduce rapidly water level, in the time that wetland operating water level drops to 2.0m, valve-off 8, open flowing water Valve 11, discharge water to operating water level, on this water level, form the thermal insulation layer of ice sheet 21 and gas cloud 22, now top ventpipe 12 is opened, ensure the dissolved oxygen concentration of subglacial.
Vertical current and horizontal flow can transform, and the transformation period should determine as the case may be, and winter transportation behavior vertical current, severe winter operate to horizontal flow as before.
Because bed height of the present invention exceeds filler 0.6-0.7m, above filler, form the ice sheet of 0.4-0.6m and the insulation air heat insulating layer of 0.1-0.2m winter.
The strong emergent of upper strata plantation soil removability of artificial swamp of the present invention, the closely knit terrestrial stem of plant in winter has played to the formation of ice sheet the effect of supporting.
