embodiment 2
A method for irrigation canals and ditches ecology of hardening transformation, is made up of following steps:
Step 1: the sclerosis cleaning of irrigation canals and ditches and the ecological ditch of breast wall type and the ecological ditch alternative expression of float type build Region dividing
With instrument by the weeds around sclerosis irrigation canals and ditches 1 canal wall and silt displacement, the ecological ditch of breast wall type that the irrigation canals and ditches 1 cleared up first mark off about 200m builds region, then, after reserving the blank irrigation canals and ditches of 100m, the ecological ditch of float type that the irrigation canals and ditches 1 cleared up mark off about 201m again builds region;
In step 1, the ecological ditch of breast wall type builds region and the ecological ditch of float type builds the blank irrigation canals and ditches of the 100m reserved between region, the ecological ditch of breast wall type and the ecological ditch alternative expression of float type build, in the blank irrigation canals and ditches of the ecological ditch upstream of float type, aerator 16 is set, oxygen in air can be forced to shift in liquid by aerator 16, increase the dissolved oxygen in water, prevent irrigation canals and ditches 1 inner suspension body from sinking, in reinforcement irrigation canals and ditches 1, organic matter and microorganism and dissolved oxygen contacts; Thus ensure that microorganism is under the condition having sufficient dissolved oxygen, decomposes the oxidation operation in sewage, so that floating plant 9 on floating plate 8 and emergent aquactic plant II 15 absorb.
Step 2: the installation of skirting board component and the build of parting bead
On adopt fixed support 2 to be fixedly mounted on by skirting board 3 both sides canal wall that the ecological ditch of breast wall type builds the irrigation canals and ditches 1 in region and the bottom of irrigation canals and ditches 1, leave the distance of 0.25m between skirting board 3 and both sides canal wall, skirting board 3 and irrigation canals and ditches 1 diapire leave the distance of 0.4m;
Two floating plate parting beads 7 built respectively by the irrigation canals and ditches 1 both sides canal wall in float type ecological ditch structure region, and the parting bead 7 on the canal wall of both sides is oppositely arranged, and homonymy two parting beads 7 are at a distance of about 201m;
Step 3: matrix is filled
Filling substrate 4 between skirting board 3 and both sides canal wall and bottom skirting board 3 and irrigation canals and ditches 1; On the coast to filling substrate 4 in the plant cultivation hole 14 on floating plate 8; Described matrix 4 is made up of slag and haydite, the upper strata of matrix 4 is for ease of the haydite of microorganism adsorption, and lower floor is the slag stronger to nitrogen phosphorus absorptive capacity, and the haydite layer of matrix 4 and the height of slag layer are than being 1:4-1:5, the particle diameter of haydite is 60 ~ 100mm, and the particle diameter of slag is 30-40mm.Matrix 4 adopts slag and haydite layering to form, because the absorptive capacity of slag to nitrogen phosphorus is stronger, nitrogen phosphorus in irrigation canals and ditches effectively can adsorbed and is being fixed, and matrix 4 upper strata adopts the haydite being convenient to microorganism adsorption, can adsorb the microbial colonization that the water plant root system of plantation is created, prevent that current in irrigation canals and ditches are too fast to be washed away microorganism.Keep the stability of microbial colonization, make microbial colonization while fixing, the microorganism that haydite adsorbs, the nitrogen phosphorus fixing to slag carries out trans-utilization, forms vertical nutrition channel, for the water plant being planted in matrix 4 provides nutrient, promote the growth of water plant, meanwhile, improve again the regeneration promoting slag adsorption capacity, improve purification efficiency.
Step 4: the plantation of water plant
Plant emergent aquactic plant I 5 in matrix 4 between skirting board 3 and both sides canal wall, in the matrix 4 between skirting board 3 and trench bottom, plant planting submerged plant 6,
Described plants emergent aquactic plant I 5 for cattail and Scirpus tabernaemontani collocation plantation, Cattail Plant well developed root system, arrange in pairs or groups with Scirpus tabernaemontani and be conducive to purifying water, the heavy metal of cattail energy resisting high-concentration and it is adaptable, growth is fast, accumulation ability is strong, effectively can purify the phosphorus in the tail water of farmland, nitrogen, CODcr, BOD
s, the pollutant such as total suspended matter (servant S);
Planting submerged plant 6 is planted for waterweed in matrix 4 between bottom skirting board 3 and irrigation canals and ditches 1, waterweed not only can release a large amount of oxygen in photosynthetic process, a large amount of harmful ammoniacal nitrogen, carbon dioxide and some the organic decomposition thing that also constantly produce in Absorbable rod water, pH value can be stablized, make water quality keep neutral meta-alkali, increase the transparency of water body;
In plant cultivation hole 14 on floating plate 8, the floating plant 9 of plantation is Azolla imbricata, Azolla imbricata can reduce water body salinity, adjustment water pH value, the effect of purifying water body and enrichment potassium element, it is high-quality green manure and fish, poultry forage grass that Azolla imbricata is not weighed, also can to the strong adsorption effect of the heavy metal ion such as Cr, Cd, Cu, Mn, Zn and the volatilization to Se element; Emergent aquactic plant II 15 is canna, and canna can not only beautify the life of people, and again can sulfur dioxide absorption, hydrogen chloride, and the hazardous substances such as carbon dioxide.
Step 5: farmland tail water is introduced
Farmland tail water is opened a sluice gate to be incorporated in irrigation canals and ditches 1; And the floating plate 8 of having planted water plant is put in the float type introducing farmland tail water ecological ditch structure region.
Described skirting board 3 adopts anti-aging plastics or the prefabricated demountable structure plate of rubber-plastics material, the side of skirting board 3 is provided with groove 11, opposite side is provided with contiguous block 12, and groove 11 and contiguous block 12 are provided with screwed hole 13, achieve Fast Installation and the dismounting of skirting board 3, shorten the construction period, be easy to safeguard and install, improve efficiency of construction.
Floating plate 8 in the ecological ditch of described float type adopts anti-aging plastics or the prefabricated demountable structure plate of rubber-plastics material; Floating plate 8 is spliced by sub-floating plate 10, the side of sub-floating plate 10 is provided with groove 11, opposite side is provided with contiguous block 12, groove 11 and contiguous block 12 are provided with screwed hole 13, achieve Fast Installation and the dismounting of floating plate 8, shorten the construction period, be easy to safeguard and install, improve efficiency of construction.Described sub-floating plate 10 is provided with plant cultivation hole 14 uniformly, plant cultivation hole 14 is through hole, its bottom is provided with the string bag, so not only can prevent the matrix 4 in plant cultivation hole 14 from dropping in irrigation canals and ditches 1, secondary pollution is caused to water body, the root system also helping plant extend in water from the mesh of the string bag, purifies water.
The method of a kind of irrigation canals and ditches ecology transformation of hardening provided by the present embodiment, between the planting season of whole water plant, effectively can tackle the nitrogen phosphorus discharge in sclerosis irrigation canals and ditches in the tail water of farmland.The present invention cuts down the total nitrogen 40kg/hm discharged in the tail water of farmland in sclerosis irrigation canals and ditches altogether
