Description

Sewage restorative procedure
Technical field
The present invention relates to water environment ecological restoration technical field, and in particular to a kind of utilization plant carries out the side of sewage reparation Method.
Background technology
Water pollution is a key factor of global shortage of water.Body eutrophication is most generally deposited in water pollution Phenomenon.Trace it to its cause is exactly industrial pollution, town domestic sewage pollution and the big arch-criminal of widespread pollution from the overuse of fertilizers and pesticides in rural area three.
Gold silver grass 2 is grass, is uprightly grown thickly, and with very strong tillering ability, individual plant every year can 80 plants of tiller More than, can be rated as the king in grass.Gold silver grass 2 is by African wild Herba penniseti and grassiness hybridization and the Jing limit acclimatization cultures of 18 years Form.It is subordinate to Angiospermae, Monocotyledonae, grass family, Pennisetum.At present, although also have by gold silver grass No. 2 be used for The report of purification sewage disposal, such as publication No. are the A of CN 104206140.But, by gold silver grass No. 2 using it is biological floating bed enter There is difficulty in row phytoremediation, because the gold silver grass 2 of soil cultivation is directly placed into into floating bed processing, easily occur rotten, enter And the phenomenon of death, do not reach the purpose of long-term repair sewage.
The content of the invention
To solve the difficult problem that existing sewage reparation is present, the present invention proposes a kind of sewage restorative procedure, the sewage reparation side Method is processed by No. 2 by gold silver grass through water planting, can be efficiently solved body eutrophication, water quality with biological floating bed combination and be mixed Turbid, bad smell problem.
The technical scheme is that what is be achieved in that:
A kind of sewage restorative procedure, comprises the following steps:
(1) the cultivation of No. 2 Rooted Cuttings of gold silver grass:
A, No. 2 cane parts of the growth selection gold silver of 3 months and more than 3 months grass, are cut into stem section;
B, stem section is put in Flat bottom container processes 28-32s with the mixed solution of adverse-resistant agent and cytothesiss agent, mix molten Liquid wants the stipes of submergence stem section;
C, the stem section handled well of step b is put into rapidly in clear water reserviors carries out water planting nursery, stem section should not be totally submerged Inside clear water, water planting is until grow the pure white fibrous root of 0.2-0.5cm length around stipes;
(2) biological floating bed reparation:The Rooted Cuttings that step c is cultivated are put in the fixed container of upper and lower opening, then should Fixed container is fixed on above biological floating bed, and biological floating bed being put in contaminated river for filling Rooted Cuttings is repaiied It is multiple.
Further, the step a stem section length be 8cm, wherein the following partial-length of stipes be 2cm, stipes above section Length is 6cm.
Further, mixed solution is higher than stipes 1cm in step b.
Further, the depth of water is 6cm in the step c clear water reserviors, and stem section surfaces 2cm.
Further, it is described it is biological floating bed made with little Phyllostachys pubescens Mazei ex H.de Lebaie, the biological floating bed length is respectively 3.4m and 1.6m with wide.
Further, the step (2) it is biological floating bed repair need periodically to gold silver grass No. 2 prune so as to height keep 0.8cm。
Further, (2) the step should not gather in after middle gold silver grass 2 enters winter, wait Second Year temperature temperature stabilization to exist When 10 DEG C, biological floating bed gold silver grass 2 above is sliced off positioned at water surface part above, allow it to sprout sprouting continued growth and enter Row sewage is repaired.
Beneficial effects of the present invention:
The present invention is processed the mixed solution of the careless No. 2 stem section adverse-resistant agent of gold silver and cytothesiss agent, is repaired stem section and is broken Cell at damage, stem section transverse section is infected when preventing nursery, then carries out water planting nursery process, and stem section well developed root system solves soil The rotten problem that nursery occurs when processing for floating bed, and can effectively solve the problem that body eutrophication, water quality is muddy, bad smell is asked Topic.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is biological floating bed structural representation of the invention;
Fig. 2 is fixed on the structural representation in floating bed for mineral water bottle.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.
A kind of sewage restorative procedure, comprises the following steps:
(1) the cultivation of No. 2 Rooted Cuttings of gold silver grass:
A, No. 2 cane parts of the growth selection gold silver of 3 months and more than 3 months grass, it is 8cm stem sections to be cut into length, wherein The following partial-length of stipes is 2cm, and stipes above section length is 6cm, and 10 1 have been tied up standby;
B, stem section is put into height to be processed with the mixed solution of adverse-resistant agent and cytothesiss agent in the Flat bottom container of 5cm 28-32s, stipes 1cm of the mixed solution higher than stem section;
C, the stem section handled well of step b is put into rapidly in clear water reserviors carries out water planting nursery, the depth of water in clear water reserviors For 6cm, stem section surfaces 2cm, and temperature should be maintained at more than 15 DEG C, less than 35 DEG C of environment, and water planting is until long around stipes Go out the pure white fibrous root of 0.2-0.5cm length, general 20-25 days or so;
(2) biological floating bed reparation:Referring to Fig. 1, made with little Phyllostachys pubescens Mazei ex H.de Lebaie it is long biological floating bed with 1.6m with wide respectively 3.4m, 5.44 ㎡ are accumulated per bed surface, 36 plants of gold silver No. 2 Rooted Cuttings of grass can be carried;The empty mineral water bottle of 560ml is taken, by bottom of bottle cut-out lasso It is fixed between bamboo and bamboo in the cave of width 2.5cm (such as Fig. 2), and the Rooted Cuttings strap for having cultivated is fixed on into mineral water In bottleneck, then floating bed is put in water;
It is biological floating bed repair need periodically to gold silver grass No. 2 prune so as to height keep 0.8cm.Gold silver grass 2 enters Should not gather in after entering winter, wait Second Year temperature temperature stabilization at 10 DEG C, biological floating bed gold silver grass 2 above is located at into water Face part above is sliced off, and allowing it to sprout sprouting continued growth carries out sewage reparation.
In the present embodiment, gold silver grass 2,2 Ge Yuehou Jing environmental administrations are planted in its water body using plant ecological floating bed Detection shows:Total nitrogen drops to 1.85mg/L and reduces 1 times from 3.65mg/L;Total phosphorus drops to 0.07mg/L and reduces from 0.33mg/L 5 times, water quality becomes clear, free from extraneous odour.Therefore, the effect of No. 2 purification sewage of gold silver grass is obvious.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
