Description
Technical field
The present invention relates to the eutrophy lake and administer technical field, relate in particular to the technical field that suppresses blue algae growth.
Technical background
In recent years, along with the development and use of the quick increase of the continuous development of society, population and lake resource and water resources is prevented and treated relative deficiency, lake pollution is on the rise, and wherein emphasis lakes such as Dian Chi, Chaohu and Taihu Lake are particularly serious.The outburst of wawter bloom then is a principal character of lake severe contamination.The outburst of wawter bloom makes that water taste becomes that raw meat is smelly, the DO reduction of profundal zone, the release of toxic substance, the increase that influences water supply quality and water purification cost, the variation of aquatic ecological.Wherein the easiest formation wawter bloom, range of influence is the widest, toxicity is the strongest is the Cyanophyta algae.Blue-green algae is a kind of former at first ancient algae prokaryotic organism, often breeds in a large number summer, and there is the floating foam of stench flavor corrupt dead back in water surface formation one deck blue-greenish colour.In the lake of outburst blue-green alga bloom, dominant population is generally microcystis kutz or Anabaena, and in addition, the algae toxin toxicity that microcystic aeruginosa produced in the microcystis kutz is maximum.Therefore, about how controlling and remove the problem that algae in the polluted lake and algae toxin have become numerous Chinese scholars researchs effectively.
The most frequently used control algae and algae removal technology generally can be divided into chemical technology, physical technique and biotechnology at present.
Chemical algae removing technology: control the algae grows breeding by throw in chemicals (as the weedicide on copper sulfate and ferrous sulfate, titanium dioxide bromine, some wide spectrum meanings etc.) to water body.Though this method is simple and easy to do, time saving and energy saving, this method can not fundamentally be improved water quality, and is opposite, along with getting more and more of dosage, the continuous replacing of pharmacy variety, to second environmental pollution also in continuous increase, thereby make water quality environment form serious vicious cycle.
The physics algae removal technology: that uses in many supplying drinking waters waters (as reservoir) at present is many, comprises that mainly the clay flocculation removes algae, mechanical process except that algae, microfiltration membrane and gac and the method for dredging is removed algae etc.And to utilize gac to remove Microcystin (MC) also be each Running-water Company method relatively more commonly used at present.This method can directly reduce TN and the TP that is accumulated in the bed mud of top layer to a certain extent, but microorganism and living environment thereof that gathering nitrogen phosphorus function is arranged in the destructible bed mud cause most of the nitrogen phosphorus can't be built up in the bottom, lake, and be dissolved in the lake water.
Biological algae removal technology: utilize cultivate biological or cultivate, the vital movement of the biology of inoculation, to water pollutant transform, degraded and transferance, thereby water body environment health is restored.But use this method might cause beyond thought secondary pollution.As Chinese patent (publication number: CN101134623) proposed a kind of method of comprehensive treatment of polluted water by inhibiting growth of blue algae.This method comprises: on contaminated waters, become " Lian Chi " with float type fence circle, " Lian Chi " cast anchor is fixed on the water surface breeding Herba Eichhorniae in " Lian Chi "; Control Herba Eichhorniae breeding quantity is in time salvaged the Herba Eichhorniae of " superfluous relatively "; To salvage the Herba Eichhorniae of " superfluous relatively ", can be used for increasing newly " Lian Chi " breeding breeding, also can produce biogas, as the new forms of energy raw material through anaerobically fermenting.Though this method has reduced the nitrogen and phosphorus content in the lake water to a certain extent, how to salvage the Herba Eichhorniae that covers with to suffering from and but become problem demanding prompt solution.
More than three kinds of traditional methods starting point of administering wawter blooms be with the algae be direct object (physical method removes algae, chemical agent kills algae) or indirectly object (biological method removes N, P) control and remove.These traditional methods all reach purpose except that algae in short-term, but in the long run, the drawback that these methods show makes it to become the effective ways except that algae.Therefore, the research theme that to seek a kind of effective and favourable algae control method be Chinese scholars.
Present numerous scholar mostly carries out the research of algal control around the influence factor of algal grown.The influence factor of algal grown comprises illumination, temperature, pH, nutritive salt, CO
2Etc. condition, and temperature, N/P ratio, pH value are considered to influence most important, the most basic environmental factor of Microcystis aeruginosa growth.The same with other influence factors, to be studied comparatively thoroughly by people about pH to the influence of algal grown, research thinks that various algal growns all have its suitable pH value scope, pH influences the algae grows reproduction speed, and then has influence on the succession of kind; PH all produces certain influence for composition and the scale of plant plankton, generally speaking, and blue-green algae preference higher pH.Yet the mode that changes change pH values in these processs of the test is chemical reagent such as using NaOH, HCl, and is that the contrast condition obtains different inhibition degree with the initial value that changes pH mostly.This is the shortage actual operation for utilization change pH administers actual pollution for the principle of condition inhibition algal grown lake.
Summary of the invention
Order of the present invention is to provide a kind of method that suppresses blue algae growth, does not need to use the soda acid chemical reagent, the growth of blue-green algae in the inhibition rich lake that just can be effective and favourable.
