Description
Technical field
The present invention relates to a kind of controlling device and administering method more particularly to a kind of floating algae controlling devices and administering method.
Background technique
Currently, the previous economic model for pursuing high growth simply of China's transformation implements a systems such as production capacity conversion upgrading
Column policy, economic structure are just being undergone from extensive style to intensive transformation, meanwhile, Ecological Civilization Construction is also increasingly able to weight
Depending on, blue mountains and green waters is exactly that the idea of development of Kingsoft Yin Shan is rooted in the hearts of the people, to river, lake, library, canal improvement in, by establishing river
Long system, effectively increases governance efficiency；However, the water area ecological environment in some areas restores difficulty still very greatly, before one's early years
The outburst of the extensive algae of the Dian Chi in Yunnan, yellow Bohai Sea Area is that the wawter bloom of representative and red tide ecological incidents are also reported again and again
Road causes a large amount of concerns of people.
Studies have shown that living closely bound up inland waters with people, algae when wawter bloom occurs, it is in the majority with cyanobacteria.It is blue
Algae is most original, most ancient algae, like living in organic matter is abundant and the higher water body of pH value in, pyrophilous, energy of surviving
Power is strong, some cyanobacterias can live in 60~85 DEG C of hot spring；Some types can also be with bacterium, moss, fern and gymnosperm symbiosis；
Some can also penetrate in calcareous rock or shell in (such as lime-boring algae) or deep subsoil (such as edaphocyanophyceae), in distributed in nature
It is very wide.According to harmfulness size, cyanobacteria can substantially be divided into that Microcystis aeruginosa, spirulina, Anabaena, quiver algae.Wherein with Microcystis aeruginosa
Harm is maximum.Microcystis aeruginosa common people habit is referred to as blue-green alge, and it is thick to form a thickness in surface layer of water for summer high temperature season mass propagation
Be similar to paint shape substance.Cyanobacteria once becomes dominant population, and temperature is higher, and breeding is faster.More seriously, due to
The excessive multiplication of cyanobacteria, it is suppressed that the breeding of other algae, the dead individuals of some types (such as Microcystis aeruginosa) decompose also in cyanobacteria
It can generate Microcystin (microcystins, abbreviation MCs), a large amount of MCs are contained in about 50% green tide.MCs is in addition to straight
Connect to fish, people and animals generate murder by poisoning except and liver cancer major incentive.MCs is heat-resisting, is not easy to be decomposed by boiling water, poisons in freshwater
In cyanophycean toxin have become global environmental problem, cyanophycean toxin poisoning frequent occurrence all over the world.
With the arrival of high temperature season, breeding water body bait throwing in increases, and cyanobacteria is easier to largely break out.Recent study shows
The generation of cyanobacteria and the nutrient proportional imbalance of water body also have much relations.The photosynthesis of cyanobacteria is strong, leads to water body
PH value sharply increases, and the rising of pH further promotes its breeding, so forming vicious circle.And work as cyanobacteria mortality
Afterwards, one unpleasant bad smell is issued, can be decomposed while consuming a large amount of oxygen and generate a large amount of toxin.It will cause cultivated animals
Loss of appetite, immunocompetence decline, nondigestible and since the outer layer of most of cyanobacteria has one layer of glue quilt, fishes and shrimps miss
Easily cause enterogastric diseases after food, substantially increases probability of illness.When cyanobacterial bloom occurs, the water surface is by thick blue-green lake
Indigo is covered, and is accumulated by wind to bank, and can not only give out a foul smell taste, influences feeding management, and to aquatic products industry sustainable development
Exhibition and the target for realizing green aquatic product cultivation, will cause huge negative effect.
The reason of cyanobacteria occurs mainly has the following,
Temperature.Cyanobacteria generally requires can just break out on a large scale under hot conditions, when 25-35 DEG C of water temperature, the growth of cyanobacteria
Speed just can be faster than other algae, therefore temperature is one of principal element of Blue-green Algae Fast Growth.But in production practice, especially summer
When high temperature algal bloom, in face of of such a size waters, carries out temperature regulation and be difficult to operate, moreover temperature change can be to its in waters
The ecological environment of allogene causes crisis, influences ecological safety.
Water eutrophication is also one of inducement.Raiser increases aquatic products seed stocking rate, bait throwing in improve yield
Amount only focuses on artificial cultivation and protection of resources of the yield without focusing on water plant, causes breeding water body eutrophication, water colour is in
" sweet mung bean soup " color.Bottom of pond deposits a large amount of mud, not only black but also smelly, pollutes environment, causes " light pool ", also referred to as breeding water body " desert
Change ", this to put undue emphasis on consumer, the ecosystem for ignoring analyst and the producer is extremely uneven.Cause pool etc. no
The similar waters of flowing is often easier to break out cyanobacteria.But changing water will increase aquaculture cost, and it was verified that temperature other
In the case that external condition is constant, it is not every time effective for frequently changing water.Lake serious for eutrophication, takes
" dirt is released in diversion " is not a long-term plan.And the change of water quality after water is changed, can equally cause to biology in waters stress be anti-
It answers, influences survival rate and quality, in particular with the aggravation of shortage of water resources degree, this mode for administering cyanobacteria also can not
It takes.
Organic phosphorus is the necessary factor of blue algae growth, remove waters in it is organic phosphorus currently, especially people are paid attention to, make
It is well known with the bulletin of non-phosphide detergent, but individual areas also largely can be rich in organic phosphorus cleaning system using other
Agent, it is wider due to being related to face, it is not easy to supervise, needs the positive cooperation of all people that can just carry out, so, it is difficult to play in a short time
Effect, to realize rapidly to cyanobacteria administer there are certain difficulty.
Nowadays, people prevent blue algae bloom from also coming up with many methods, and control method can be divided into physical method and chemistry
Method two major classes have thorough cleaning disinfection, periodic replacement fresh water and manually the modes such as skim for physical method, thorough
Bottom cleaning disinfection, periodic replacement fresh water have discussion above, not only at high cost, but also produce effects less；It manually skims, because not having
There is the tool for claiming hand to largely being salvaged in entire waters, often produces little effect after increasing man power and material's consumption.
There are many kinds of chemical method prevention and treatments, wherein using the cyanobacteria feature more more sensitive to copper ion than other algae, by copper
Preparation is used as algal control, algicide.But the copper ion of high concentration can cause phytoplankton mortality, make water body severe depletion of oxygen.Copper
The use of preparation can also cause prawn retention toxicosis, cause its liver, kidney tissue damage, influence to grow；Meanwhile excessive excess copper
The use of preparation can also corrode the gill filament of shrimp, form the diseases such as the black gill.Human health is finally jeopardized through food chain.Therefore, copper
Preparation causes secondary pollution using to environment, causes the harm of biological chain often irreversible, should not use.
Using tea bran administer cyanobacteria, be suitable for blue algae bloom initial stage, studies have shown that because tea bran contain Tea Saponin, except pair
It is larger to being poisoned using hemoglobin as other aquatic livestocks of the carrier of oxygen outside shrimp aquaculture, it is not easy to use.
Selectivity fertilising improvement cyanobacteria, which is carried out, using the nitrogen fixation of cyanobacteria is conducive to consolidating for cyanobacteria although low N/P ratio
Nitrogen, high N/P ratio are conducive to green alga breeding.External some scholars think, when N/P ratio is close or equal to 16:1, can be effectively controlled
The outburst of Azotica.But other substances such as nitrogen class so, are often introduced, other yuan such as nitrogen oxides in waters are caused
The ratio variation of element, is equivalent to the secondary pollution to waters, is also unfavorable for carrying out.
Equally, permanganate, aluminum sulfate, composite ferrate chemicals, liquid chlorine, hypochlorous acid, ozone and hydrogen peroxide are utilized
Equal chemicals not only leave preparation and cause secondary pollution in waters, but also are only also a kind of palliative, it is necessary to cautiously make
With.It is more main, first is that the cyanobacteria corpse after removing algae with chemical agent remains in water body, and constantly discharges algae toxin, harm
Property become it is longer and more hidden；Second is that chemical algicide is very big on the influence of water body other biological, the river after chemical agent is used
It is unfavorable for biological resuming；Third is that being only capable of having control action to Measures of Algae in Water Body in a short time using chemical algicide, due to not
It can thoroughly kill, again revivable after a while, sometimes because algae has drug resistance or even is further intensified, water body will be a kind of
Vicious circle.It can be said that administering river with chemical method is " drinking poison to quench thirst ".Country has limited chemical method and has controlled in river
Use in reason.
The above analysis obtains, after wawter bloom occurs in waters, current physics algae-removing method and chemical algae removing method
There are low efficiency, it is at high cost, on a large scale except the drawbacks such as algae side effect is big, from practical application, there is also gaps.Therefore, it is badly in need of finding out
A kind of practicable algae administering method.
