Abstract
The invention discloses a construction method of a furrow-shaped slow flow ecological purification system, belonging to the technical field of water pollution control and ecological repairing. The method comprises the following two steps of: determining a constructing region and constructing a furrow; selecting a slow slope range with the terrain slope which is less than or equal to 15% as the constructing region; digging a plurality of parallel interval shallow grooves (1) in a vertical direction of an inclined slope; continuously or discontinuously filling crushed stones (5) in the shallow grooves; planting humidity-proof shrub plants (4) in the shallow groove; stacking soil furrows (2) at one sides of the shallow grooves with the lower terrain; and planting arbor or shrub plants (3) on the soil furrows. The construction method has the advantages of simple construction method, easiness for operation, small engineering amount, little investment and strong operability; the construction method can be used as a process method of newly-established ecological repairing engineering and also can be used as a modified method on the basis of the existing repairing engineering; and the construction method has wide applicability, does not disturb the previous system and has a wide application prospect on the aspect of managing surface source pollution.
Description
(1) technical field:
The present invention is a kind of construction process of furrow shape cross flow ecological purification system, belongs to water pollution control and ecological reestablishment field.
(2) background technology:
Furrow is formation of land mode common in agricultural tillage, and wherein the ridge is above the ground level, and ditch is for the ditch of arranging, filling with, spread manure etc., is lower than ground, and continuous furrow can form the ground that height rises and falls.The form of furrow used for reference have certain value and significance in water pollution control and the ecological reestablishment field, especially for the purification of overland flow, furrow is better to pollutant interception clean-up effect.
Correlative study shows, the surface infrastructure of building the up concave type form has significant environment, ecological effect, can the recharge of groundwater resource, prolong the ground concentration time, cut down surface flow, increase the soil infiltration water yield, improve the multiple ecological environment effects such as regional Eco-hydrological environment, build the recessed degree of depth (0.1～0.3m), the up concave type structure of area ratio (10～30%) can be cut down the surface flow of meeting the 1h rainfall generation of design storm recurrence interval in 3 years substantially, and the green space system of recessed form is to N, the average removal rate of the pollutants such as P can reach about 40～50%.
According to the conclusion of the surface infrastructure research of up concave type form and the reasonable digestion of considering the engineering earthwork, the present invention proposes a kind of construction process of furrow shape cross flow ecological purification system, the orderly earthwork is carried out on the earth's surface digs, fills out, form " furrow " shape, " ditch " wherein namely is the structure of up concave type, ditch is lower than ground surface, certain lower degree of depth of digging is arranged, can carry out certain saving and purifying to rainwater, surface flow water, the ridge is to utilize the digestion of excavation original place to pile, and recovers the tall careless vegetation system of filling with at furrow.Aspect the pollution control that purifies cross flow, the method for carrying out furrow shape ecosystem structure there is no report and the precedent of using in China.The present invention is a kind of method of basis Ecological Restoration Project experience accumulation for many years, not only construction process is simple, easy to operate, and engineering quantity is little, small investment, workable, the process that can be used as newly-built Ecological Restoration Project also can be the remodeling method on existing reinstatement works basis, applicability is wide, can the disturbance original system.
(3) summary of the invention:
Method of the present invention comprises 2 steps: 1. step is for determining to make up the zone, and 2. step is for making up furrow.
Wherein, 1. step be chosen in terrain slope for≤15% gentle slope scope for making up the zone.
Wherein, 2. step be with the shallow ridges 1 of a plurality of parallel interval of slope vertical direction excavation, wherein the cutting depth of shallow ridges is 30cm, side slope ratio≤1: 2, excavation width is 1m at least, continuous or interval filling rubble 5 in shallow ridges, particle diameter 3-8cm, packed height 20cm can plant moisture-proof shrub plant 4 on the shallow ridges; Stack rib 2 in the side that the shallow ridges physical features is low, the rib width is 1m at least, side slope ratio≤1: 2; At rib plantation arbor or shrub plant 3.
Wherein, the herbaceous plant on shallow ridges and the rib is self-sow.
Characteristics of the present invention are as follows:
1. the method applicability is wide, can be used for new construction, also is applicable to the transformation of built engineering;
2. the method is ingenious, little, the small investment of engineering quantity;
3. the method is convenient, easy to operate, and technical difficulty is little, easily penetration and promotion;
3. the method environment, ecological benefits are obvious.

Fig. 1 is the construction process layout schematic diagram of a kind of furrow shape cross flow ecological purification system of the present invention;
Fig. 2 is the construction process sectional schematic diagram of a kind of furrow shape cross flow ecological purification system of the present invention;
Among the figure: 1 is rib, and 2 is shallow ridges, and 3 is arbor or shrub plant, and 4 is the moisture-proof shrub plant, and 5 is rubble.
(5) specific embodiment:
As shown in Figure 1 and Figure 2, the construction process of a kind of furrow shape cross flow ecological purification system of the present invention is as follows: determine first the structure zone, it is regional for making up for≤15% gentle slope scope to be chosen in terrain slope; Then carry out topography reform, with the shallow ridges 1 of a plurality of parallel interval of slope vertical direction excavation, wherein the cutting depth of shallow ridges is 30cm, side slope ratio≤1: 2, excavation width is 1m at least, and rubble 5 is filled at continuous or interval in shallow ridges, particle diameter 3-8cm, packed height 20cm reaches more effective removal pollutant purpose, can plant moisture-proof shrub plant 4 in the shallow ridges; The earthwork at shallow utilization excavation shallow ridges is stacked rib 2 in the low side of shallow ridges physical features, and the rib width is 1m at least, side slope ratio≤1: 2, and at rib plantation arbor or shrub plant 3.Wherein, the herbaceous plant on shallow ridges and the rib is self-sow.
Claims (1)
1. the construction process of a furrow shape cross flow ecological purification system comprises 2 steps: 1. step makes up the zone for determining, be chosen in terrain slope for≤15% gentle slope scope for making up the zone; 2. step is for making up furrow, with the shallow ridges (1) of a plurality of parallel interval of slope vertical direction excavation, wherein the cutting depth of shallow ridges is 30cm, side slope ratio≤1: 2, excavation width is 1m at least, continuous or interval filling rubble (5) in shallow ridges, particle diameter 3-8cm, packed height 20cm can plant moisture-proof shrub plant (4) in the shallow ridges; Stack rib (2) in the side that the shallow ridges physical features is low, the rib width is 1m at least, side slope ratio≤1: 2; At rib plantation arbor or shrub plant (3).
