Description
Technical field
The present invention relates to a kind of method of purifying eutrophication water body, relate in particular to a kind of method of utilizing hydrocoles, plant, microbially decontaminate eutrophication water.
Background technology
Now, eutrophication and the algal bloom outburst, the aquatic ecosystem that cause are therefrom degenerated and have not only been restricted the utilizability of lake resource, and the health that has directly affected the mankind is survived and socioeconomic sustainable development, it has been a global great environmental problem, the reparation of degeneration aquatic ecosystem is also a global hang-up
Also do not occur up to now can large-scale promotion mature technology, the ecosystem is the huge system of a complicated opening, between the huge component units of the quantity of system, there is complicated linear and non-linear contact, can in different levels, show diversity, self-organization and the complicacy of structure and function.Therefore, being difficult to find one not add improves and blanket technology, for different lakes, should there is unique design, any single technology is all difficult to the effect that reaches lasting and stable, sometimes be not only difficult to control the outburst of eutrophication algae population, even also can cause the increase of algae bio amount, eutrophication to present and increase the weight of trend.
According to the study, Microcystis aeruginosa is more adapted to grow in the environment of eutrophication, is approaching or is reaching under overweight eutrophic state, and Microcystis aeruginosa still can maintain the growth of biomass.Under suitable nutritional condition and illumination condition, Microcystis aeruginosa amount reproduction, then rises to the water surface by the regulating and controlling effect of pseudo-ghost, breaks out into wawter bloom.After breakout of water bloom, transparency further declines, and water body light intensity further weakens, and blue-green algae is the organism that adapts to low light, and its buoyancy adjustment can make it be trapped in any position in water body photic zone, only unique energy derive of waterplant, algae competition.Blue-green algae occupies superiority gradually like this, and consequence is that submerged vegetation fades away, and water body is muddy and stable this state of maintenance further.The minimizing of submerged vegetation, causes dissolved oxygen to decline, and causes the minimizing of attached plant and biology and eqizoa.And due to blue-green algae amount reproduction, mortality is decomposed and is consumed in a large number the dissolved oxygen in water, causes aerobic high fish kills.The decline of water body DO causes lake-bottom to be tending towards anaerobism, redox potential sharply declines, sediments is constantly converted in reduced state, impel again the nutritive substance being deeply hidden in bed mud to discharge with reduction-state, add the circulation of water body and nutrition, further increase the weight of body eutrophication, be more conducive to the generation of blue-green algae.
Blue-green algae has special blue-green algae glue and polysaccharose substance, the blue-green algae of each unit cell shape very easily connects again agglomerating, in blocks, the filter feeder of most of kinds lacks these blue-green algae glue and the single-minded digestive ferment of polysaccharose substance, thereby digests and assimilates difficulty, easily causes being short of food and hungry death; And blue-green algae edibility poor, can digest and assimilate and be of low nutritive value, therefore be difficult to become the food that rimary consumer likes; In addition the toxin that blue-green algae produces can kill fish, wildlife, even jeopardize the mankind.Once blue-green algae death, decomposition in water body, its toxin is just released in water body, and water body is caused to very large pollution.Once comprehensive these factors make blue-green algae form water body dominant population, in the situation that there is no effective external intervention, water body is absorbed in a kind of vicious cycle, becomes the ecosystem of continuous degeneration.
The eutrophication breakout of cyanobacteria blooms that constantly aggravation causes, has a strong impact on the performance of aquatic ecosystem service function.Blue-green alga bloom broken out the cancer into eutrophication aquatic ecosystem, control Blue-green Algae Fast Growth and also become a global difficult problem.For ecological recovery and the inhibition Blue-green Algae Fast Growth of eutrophication water, carried out a large amount of difficult exploration and practices both at home and abroad, the method for taking is roughly divided into three kinds, i.e. chemical method, Physical, biological methods.
Wherein, chemical method comprises and uses inorganic and organic chemical reagent to seal bed mud, use by the active chemistry algal control of extracting in natural biological except algae, with Inorganic chemicals.
Chemical treatment is the solution that solves algae pollution most convenient, but on ecology, this is the worst method, because pharmaceutical chemicals and their degradation production can finally run up in human body by biologic chain, uses chemical agent can cause the secondary pollution of aquatic ecosystem.Importantly, chemical treatment can not be eliminated this basic problem of overnutrition, once pharmaceutical chemicals is decomposed, dilutes, the amount reproduction of algae will occur again, need chemical treatment continuously, so chemical agent removes algae, can only serve as emergency schedule use rather than the effective measure as life-time service.
In a word, use chemical agent to administer algae and water pollution and also must pay special attention to its long-term negative effect, will cause serious secondary pollution to water body by the flocculate technology of algae, sealing bed mud of chemical agent, have a strong impact on water supply, the amusement function performance in lake, the public is difficult to accept.
Physical comprises that external source cuts dirt, drainage dirt removal, Sediment Dredging, watercourse aeration, machinery and fish for except algae, electromagnetic method are except algae, plocher energy system are except algae, the water conservancy diversion that changes its course, eutrophic water irrigation etc. except algae, manpower.
It is to start with from controlling exogenous nutrition source that external source is cut dirt, in fact, even if the lake of a lot of Heavyeutrophications is after external source nutritive salt is blocked completely, the nutritive salt accumulating in its bed mud still can discharge in water body, the Heavyeutrophication of water body still can continue the long duration, because bed mud is actually a huge nutrition library, so water body still can algal bloom frequently break out in the extremely very long time, only depend on and control the eutrophic state that the input of exogenous nutrition salt is difficult to fundamentally improve in the not oversize time lake, must be aided with the measure that other controls endogenous pollution, but the measure of controlling external source pollution is again the prerequisite of administering lake eutrophication, if not controlling external source pollutes, any measure is all difficult to the effect maintaining a long-term stability.
In a word, in Physical, drainage dirt removal, watercourse aeration, external source are cut the measures such as dirt, Sediment Dredging, coastal belt, structure lakeside wetland, to start with and reach the generation of respite blue-green alga bloom from reduction blue algae growth, breeding desired nutritional salt, but these physical property measures all cannot make the nutritive ingredient in water thoroughly be reduced to the limit requirement that does not produce algae in water, a large amount of facts have proved, physical property method implement after soon, along with the accumulation year by year of amount of algae, finally still can break out blue-green algae, therefore Physical also must be aided with the measure of other ecological recovery in time.
Biological process comprises the three major types such as biotechnological formulation method, ecological engineering method, biological control act.
As seen from the above analysis, lake eutrophication control has been passed by from control nutritive salt, has directly been removed algae, the difficult course to biology regulation and control, ecological recovery, has spent huge cost, but has produced little effect.Simple nutritive salt control is difficult to gather effect, it has ignored the interaction between the inner nutritive salt circulation in lake and biology, but also because internal recycle and external source are polluted and be difficult to thorough control, but control nutritive salt, it is again the prerequisite of administering eutrophication, external source point-source pollution does not thoroughly block, the control of external source pollution of area source immoderation, even if the measure of good improvement eutrophication all can be invalid again.Chemical agent or physical method are directly except algae is also difficult to reach the good result of administering eutrophication, and because being discharged into water body, chemical agent can cause secondary pollution, therefore can only meet an urgent need, its long-term toxicity effect to the ecosystem also must be monitored always, in order to avoid initiation eco-catastrophe, merely except algae is the method for curing the symptoms, not the disease.
