Description

Based on the short underwater lawn modular system without flower eel grass
Technical field
The utility model belongs to waste water control and aquatic ecosystem recovery technique field, relates to a kind of based on the short underwater lawn modular system without flower eel grass.
Background technology
Landscape water body, as the important component part of urban environment, more and more obtains the favor of people.There is the defects such as water body flow is poor, coverage of water is less, the depth of water is more shallow, water body self-purification ability is poor in landscape water body, and be subject to greening irrigation, fertilising and rainwash water body pollution and make water quality deterioration.At present, landscape water body and water body in lake eutrophication, Blue-green Algae Fast Growth problem become increasingly conspicuous.
Conventional landscape water body or each defectiveness of water body in lake water treatment mode: physical equipment processing cost is high, and chemical treatment easily causes secondary pollution, and microbiological treatment needs frequent maintenance.At present, a kind of method that water ecological setting reparation is considered to low cost, not easily produces secondary pollution, prevents and treats body eutrophication sustainably, and in water surrounding restoration of the ecosystem process, a step of most critical is exactly the structure of submerged vegetation.The growth of submerged plant can increase Dissolved Oxygen in Water content, absorbs water nutrition material, reduce bed mud disturbance increase water transparency.Therefore, the growth of submerged plant plays critical effect in purification of water quality.
The implantation methods of existing submerged plant mainly contains cuttage, seeding method, method for transplanting etc.The lower water operation of artificial cuttage kind planting submerged plant palpus is larger to human and material resources consumption; Seeding method kind planting submerged plant comparatively need grow up to live time; Method for transplanting is relatively suitable.But the submerged plant of these methods plantation due to plant higher, harvesting is safeguarded frequent, and these methods can not successful Application in the more shallow water body of water body, particularly cannot implement in Small-scale Landscape Water Bodies of the hard end.And turf carries out submerged plant recovery and can cause secondary pollution to water-bed environment under the module-type water cultivated with plastics or other non-degradable media.Turf under the module-type water cultivated with cotton pad or straw pad, one is insufficient strength, and also having one is need to carry out sewing work, complex operation, inconvenience.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can be used for high compared with shallow waterbody, intensity, operate easy to use based on the short underwater lawn modular system without flower eel grass.
The technical solution of the utility model is as follows:
Based on a short underwater lawn modular system without flower eel grass, it comprises the upper bed course, nutritive layer and the underlayer that connect successively, and wherein, nutritive layer is made up of lake silt; Upper bed course and underlayer, and nutritive layer surrounding is the reticulated structure of being worked out by degradable biological material shredded coconut meat and albumin glue; The knitting tightness of underlayer is larger than upper bed course; On upper bed course, plant the short nothing flower eel grass being implanted with and cultivating, the short mesh of root through upper bed course without spending eel grass, root bundle is in nutritive layer.
Upper, middle and lower-ranking namely go up bed course, nutritive layer, underlayer thickness be respectively 0.2-0.6cm, 2-5cm, 1-2cm.
The porosity of upper bed course is 70-80%, and the porosity of underlayer is 10%.
Underwater lawn modular system of the present utility model, intensity is high, operate easy to use, on upper bed course, planting the short nothing flower eel grass cultivated, just can monoblock moving on in hard (namely substrate is hard) water body for carrying out water surrounding restoration of the ecosystem after tiling spreads.
Select short nothing flower eel grass as submerged plant in the utility model especially, this be by CN201210032406 patented method from main separation train a kind of short, without the eel grass of flower variety, it has the advantages such as short, winter hardiness by force, not easily grows the water surface, not easily spread, the four seasons are evergreen, plant height 10-15cm, suitable planting depth of water 50-150cm (the most shallow reach 30cm).
The short purification of water quality principle without flower eel grass in the utility model is as follows:
1) directly absorb N, P, the heavy metal in water body, reduce water pollution element;
2) microorganism being attached to plant surface forms biofilm system, purifies water;
3) with the competition of ecological niche, release biotic factor, suppresses the growth of algae;
4) the secondary oxygen that photosynthesis produces can kill harmful bacterium;
5) strong photosynthesis, can make organic floccus in water, forms air supporting effect, and its Quick Oxidation is decomposed, and reduces BOD 5, COD.
Also select shredded coconut meat as the main braided material of support framework in the utility model especially.Shredded coconut meat, compared with other material, have the advantages that fiber thickness is moderate, length range is reasonable, lightweight, intensity is high, good springiness, water-permeable are strong, intensive and the size reasonable of easy formation mesh-structured, plant grows in mesh, and mesh can create the environment of ventilative a, water conservation, temperature adjustment.Shredded coconut meat also has biodegradable characteristic; directly imbedding soil after 3 ~ 5 years can degradablely be detritus; detritus can increase microbial nutrition in soil; improve soil property; earth is activated and is beneficial to plant-growth; be combined can protect side slope with earth's surface after laying, effectively reduce airborne dust, and prevent the desertification of soil soil property.
The beneficial effects of the utility model:
Of the present utility modelly can solve landscape water body and water body in lake eutrophication, Blue-green Algae Fast Growth problem based on the short underwater lawn modular system without flower eel grass, repair the Water-environment Ecological System of water body, especially have great advantage to comparatively shallow waterbody.Wherein short because it has the advantages such as short, winter hardiness by force, not easily spreads, considerably reduces the tedious work of late maintaining without flower eel grass especially, and suitable especially establishing in large scale is under water in lawn system.
Of the present utility model based on the short underwater lawn modular system without flower eel grass, intensity is high, operates easy to use, can be used for, comparatively in shallow waterbody, being particularly suitable for being used in Small-scale Landscape Water Bodies of the hard end, also can be used in other water bodys such as lake.
Of the present utility model based on the short underwater lawn modular system without flower eel grass, because it uses the netted shielding layer structure of being worked out by shredded coconut meat and albumin glue, so it also has environmental protection and biodegradable characteristic.
