Description
Technical field
The present invention relates to a kind of Water microbial ecology restorative procedures, belong to ecological restoration technical field.
Background technique
Water eutrophication refers to since the plant growths elements such as a large amount of nitrogen phosphorus are discharged into water body, makes the aquatic life such as algae
Object growth and breeding in large quantities, while the speed that generates of organic matter, considerably beyond depletion rate, organic matter savings in water body destroys
The process of aquatic ecological balance.Eutrophication is global aquatic ecosystem environmental problem generally existing at present.
The restoration of the ecosystem of water body is on the basis of following the course of nature, by appropriate human intervention, using aquatic ecological
The self-control of system and self's ability repair water environment, make polluted water body reparation to original undisturbed
State, or be restored to certain suitable, stable state and self continue.
The water bodys such as urban lakes also have stable, promotion water the earth circulation of the maintenance ecosystem in addition to landscape function
Various important function, it is closely bound up with the existence of animals and plants and the mankind.And biological prosthetic especially microorganism remediation is a throwing
Money is few, high efficiency, the big emerging technology of development potentiality, have the advantages that it is quick, not will cause secondary pollution, and either exist
The algal tufa for preventing the urban water-bodies such as lake, reservoir breaks out aspect, or in terms of the improvement of water eutrophication and restoration of the ecosystem,
Microorganism ecological remediation technology can play very big effect.
Water Ecological Recovery is to administer the fundamental way and following development trend of water eutrophication.The restoration of the ecosystem of water body
It is on the basis of following the course of nature, by appropriate human intervention, using the self-control and self group of aquatic ecosystem
Ability is knitted to repair to water environment, makes polluted water body reparation to original undisturbed state, or be restored to certain
Properly, stable state simultaneously self continues.
Microorganism is the important component of natural ecological environment, and environment water not only itself has the function of restoration of the ecosystem
Can, meanwhile, various plants, microorganism included in natural water also provide the Ecosystem Service of multiplicity.These are aquatic
Plant and microorganism can be with enhancements of environment, climate regulation, additionally to water environment, each species viability environment and water ecology scape
Sight all brings wholesome effect.Although microorganism individual in nature is minimum, quantity is maximum, and distribution is also most wide.Pass through
Multiple-microorganism has cooperatively formed microorganism chain, passes through oxidation, reduction, photosynthetic, assimilation, dissimilation in water remediation
Organic pollutant is changed into simple compound, guarantees the normal function of water quality, so as to improve water body environment quality, further
Influence entire bioremediation of waters process.
Summary of the invention
The technical problems to be solved by the invention: it aiming at the problem that treatment effect of existing restoration of the ecosystem is difficult to maintain, mentions
A kind of Water microbial ecology restorative procedure is supplied.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
(1) it crushes, sieves with 100 mesh sieve after taking waste shell washing and drying, obtain conch meal；
(2) conch meal, diatomite, flyash, earthworm soil, lanthanum chloride, biological enzyme are taken, is added in deionized water, at 30~35 DEG C
2~3h of lower stirring, heat preservation are filtered after staticly settling 10~15h, are air-dried, and composite material is obtained；
(3) lake mud, composite material, iron chloride, aluminium polychloride, polyacrylamide, deionized water are taken, is fitted into spice bucket and stirs
Uniformly, soil must be repaired；
(4) it takes reparation soil to build ecosphere and transplant eel grass plant, is thrown in river, eutrophication river is detected after 10~20 days
The contamination index of road water body repeats dispensing and repairs soil until river water body meets the requirements.
The described weight of material part of step (2) is 1.0~1.2 parts of conch meals, 1.0~1.2 parts of diatomite, 4.5~5.0 parts of powder
Coal ash, 0.5~0.6 part of earthworm soil, 0.01~0.02 part of lanthanum chloride, 0.02~0.05 part of biological enzyme, 10~20 parts of deionized waters.
Step (2) biological enzyme is glusulase.
Step (3) described lake mud is the Taihu Lake lake mud for being 40~50% with filter press filters pressing to moisture content.
Step (3) lake mud, composite material, iron chloride, aluminium polychloride, polyacrylamide, deionized water weight
Part be 8~10 parts of lake muds, 3~5 parts of composite materials, 0.003~0.005 part of iron chloride, 0.010~0.015 part of aluminium polychloride,
0.008~0.012 part of polyacrylamide, 0.3~0.5 part of deionized water.
Step (4) the eel grass plant be grow fine, band root and undamaged eel grass plant, eel grass plant height be 30~
50cm。
Step (4) ecosphere is to repair soil layer, and reparation soil thickness is 5~10cm.
The present invention is compared with other methods, and advantageous effects are:
(1) present invention utilizes conch meal, diatomite, the cementing building adsorbent material of flyash, and compound earthworm soil, passes through biological enzyme
Bacterium, actinomyces and the fungi being rich in activation earthworm soil, these microorganisms not only make complex material mineralising plant be easy to inhale
The active principle of receipts, but also a series of substances for having bioactivity, such as sugar, amino acid, vitamin are synthesized, these substances
Generating makes to repair the ammonia nitrogen that soil is gone in water removal, is handed over by the ligand between the hydroxyl group and P elements on lanthanum hydroxide surface
It changes, adsorbs P elements, effectively remove the nutrients such as excessive nitrogen, phosphorus in water body, mitigate the pressure of Water Environment In Lakes, make water body
Bio-diversity reaches the self-purification capacity of enhancing water body and the technical effect of enhancing water body substance circulation, is effectively improved water environment
Capacity of self-regulation；
(2) the required raw material of the present invention is compared with horn of plenty, and its preparation process is also more easy, and the production cycle is shorter, production at
This is relatively low, more suitable in industrialized production, and under Multiple components collective effect, the effect of water body purification is more aobvious
It writes, can preferably improve the quality of water body, promote the dissolved oxygen amount in water, resist the growth of disinfect pathogen, make nitre in water body
State nitrogen and the content of ammonium nitrogen are minimized, and keep water body more limpid, dispel stench, degradation of contaminant, and then push Ecology
Preferably development.
