The variable flow wetland can be according to the adjusting of the concrete temperature Change in the external world through water distribution pipe; Carry out the mutual conversion of horizontal-flow wetland and vertical-flow wetland; It is low to have overcome the horizontal-flow wetland dissolved oxygen of intaking summer, the shortcoming that vertical-flow wetland thermosteresis in winter is many, the operation scheme that winter can the flexible wetland; Thereby reduce the influence of temperature through forming ice sheet gas cloud thermal insulation layer, guaranteed that artificial swamp can move continually and steadily under the coldcondition wetland.The variable flow wetland is through the mutual conversion of vertical current and horizontal flow, and blockage problem can slowed down even overcome to advantages such as the current scour matrix of different directions and decomposing organic matter efficient height.The present invention can be widely used in the Winter protection of large, medium and small artificial swamp, has characteristics such as pollution-free, simple to operate, reduced investment, working cost are low, high insulating effect, processing power is strong, last effect is stable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Vertically be filled with three sections fillers in the artificial swamp of the present invention, filler of the present invention is the combination of zeolite, gravel, Wingdale, slag, gac etc. and various different fillers, and present embodiment is to be that example describes with the limestone filler.About the particle diameter of two sections limestone fillers be 16-32mm, the particle diameter of stage casing limestone filler is 8-16mm; The height of limestone filler is 1.6-1.8m, and bed height degree is 2.2-2.5m; Evenly be furnished with ventpipe in the wetland; One end on limestone filler upper strata respectively is connected a water inlet pipe and water distributor with the limestone filler top; The other end of bottom respectively connects a rising pipe and receives water pipe; One water intaking valve respectively is set between water inlet pipe and water distributor and the water head tank; Rising pipe respectively is provided with a main control valve and three branch control valves with the receipts water pipe, and three branch control valves wherein are in different heights.
When artificial swamp was vertical downstream, the water distributor at limestone filler top connects the water intaking valve of water head tank to be opened with the main control valve of receiving water pipe, and the water intaking valve of water inlet pipe and the main control valve of rising pipe are closed;
When artificial swamp was horizontal flow, the water intaking valve of water inlet pipe and the main control valve of rising pipe were opened, and the water intaking valve of water distributor is closed with the main control valve of receiving water pipe.
Describe in detail below in conjunction with accompanying drawing.
Seeing also Fig. 1, is concrete structure synoptic diagram of the present invention.
Need to prove that it is left and right, upper and lower that the present invention mentioned etc., all is to be as the criterion with direction shown in Figure 1 except that specified otherwise is arranged.
High-order inlet flume 1 respectively through upper strata water inlet pipe 2 and limestone filler top water distributor 15 with the sewage of desire processing in artificial swamp.
Vertically be filled with the limestone filler of different-grain diameter in the artificial swamp, artificial swamp inside is divided into left side section 4, stage casing 5 and right section 6.Particularly, the particle diameter of the limestone filler of left side 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, packed height is 1.6-1.8m in the artificial swamp, and bed height degree 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 through separately into and out of water valve control Inlet and outlet water.Particularly, in a side of artificial swamp, be connected water inlet pipe 2 through water intaking valve 3 between the waste pipe 13 of high-order inlet flume 1 and the left side section 4, waste pipe 13 also passes through water intaking valve 14 and is connected with water distributor 15.Water distributor 15 of the present invention is water distribution uniformities, and only filler 5 places are provided with the receipts water hole in corresponding stage casing on the receipts water pipe 6.
At the opposite side of artificial swamp, the bottom of right section 6 is equipped with rising pipe 9, main control valve 7 is installed on the rising pipe 9 and divides control valve 8,10,11.The bottom of artificial swamp is equipped with receives water pipe 16, receives main control valve 17 to be installed on the water pipe 16 and to divide control valve 18,19,20.Divide in control valve 8,10,11 (18,19,20); The height location of the highest branch control valve 10 (19) will be higher than the bed height degree of artificial swamp; Minimum branch control valve 8 (18) is the bottom that is in artificial swamp, and it is the medium position that is in limestone filler that intermediary divides control valve 11 (20).With packed height 1.6-1.8m in the artificial swamp; Bed height degree 2.2-2.5m is an example, divides the control valve to design respectively in distance bed body bottom 2.4m (dividing control valve 10,19), 1.3m (dividing control valve 11,20), 0.1m (dividing control valve 8,18) position to regulate the water level of wetland unit.
Operation when the present invention moves in the winter time is:
When artificial swamp was vertical downstream wetland, water intaking valve 3 was closed with the master control valve 7 on the rising pipe 9, and water intaking valve 14 is opened, and begins water inlet by waste pipe 13 through water distributor 15; Simultaneously, receive the master control valve 17 on the water pipe 6 and divide control valve 19 to open, make water level be raised to 2.4m; Treat the icing back of upper strata water level (generally being controlled at ice layer thickness is 0.4-0.6m), by receiving water pipe 16 water outlets, valve-off 19; Open valve 18 reduces water level rapidly, when treating that the wetland operating water level drops to 2.0m; Valve-off 18 is opened flowing water Valve 20, discharges water to operating water level; On this water level, form the thermal insulation layer of ice sheet 21 and gas cloud 22, open top ventpipe 12 this moment, guarantees the dissolved oxygen concentration of subglacial.
When artificial swamp is horizontal flow, close water intaking valve 14 and the master control valve of receiving on the water pipe 6 17, open the master control valve 7 on water intaking valve 3 and the rising pipe 9 and divide control valve 10, begin water inlet by water inlet pipe 2; Make water level be raised to 2.4m, treat the icing back of upper strata water level (generally being controlled at ice layer thickness is 0.4-0.6m), by rising pipe 9 water outlets, valve-off 10; Open valve 8 reduces water level rapidly, when treating that the wetland operating water level drops to 2.0m; Valve-off 8 is opened flowing water Valve 11, discharges water to operating water level; On this water level, form the thermal insulation layer of ice sheet 21 and gas cloud 22, open top ventpipe 12 this moment, guarantees the dissolved oxygen concentration of subglacial.
Vertical current and horizontal flow can transform, and the transformation period should confirm as the case may be that winter transportation behavior vertical current, severe winter operate to horizontal flow as before.
Because bed height degree of the present invention exceeds filler 0.6-0.7m, above filler, forms 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 the effect of supporting to the formation of ice sheet.
