Description
Technical field
The invention belongs to geseous discharge high-level oxidation technology and marine eco-environment protection application technical field; the device and method that relates to a kind of prevention and control marine red tide disaster invasion and attack, advanced oxidation treatment unit and the method for the invasion and attack of especially a kind of prevention and control mariculture district red tide plankton.
Background technology
21 century is China's the most key period of history of marine cause development, when marine economy maintains sustained and rapid growth, China's nearshore marine environment pollutes also day by day serious, one of consequence that it is disastrous is exactly to cause China's immediate offshore area frequent occurrence, not only damage to the marine eco-environment, the lives and properties of more giving people particularly mariculture already cause huge loss.
Red tide refers under certain envrionment conditions, and some plant plankton, protozoon or the bacterium in the seawater be sudden propagation or highly assemble and cause the ecological unusual phenomenon of water body variable color at short notice.Red tide plankton not only relates to dinoflagellate class planktonic organism, and under specific envrionment conditions, hang worm and some bacterium in the plant plankton such as some diatom, blue-green algae, hidden algae, green haematococcus and the protozoon all can form red tide.Red tide comprises poisonous red tide and harmful algal, and poisonous red tide contains or oozy toxin by the red tide plankton body, and the fish, shrimp, shellfish etc. that cause these red tide planktons of ingesting poison or be dead; Harmful algal then causes the Marine ecosystems ANOMALOUS VARIATIONS by increment and the gathering of red tide plankton, causes the marine food chain local interruption, destroys the ocean normal productive process and threatens the halobiontic existence such as fish, shrimp, shellfish.
At present, the method for prevention and control marine red tide disaster can be summed up as three kinds of Physical, chemical method and biological processes.
Isolation is typical Physical, when the cultivation marine site suffers the red tide invasion and attack, can rapidly box for breeding or aquaculture organism be transferred to the safe marine site that red tide does not occur.The method is time and effort consuming not only, and cost is high, and because the oceanic area of generation red tide is usually very large, and vicinity generally is difficult to find safety basin, and can cause equally biological loss or the death such as fish, shrimp, shellfish in the transfer process.Oxygenation also is the physical method of commonly using, and by throwing in oxygenating machine in the cultivation marine site, can improve the anoxic conditions of water body, alleviates red tide to the infringement of aquaculture organism with this.But the action effect of oxygen enhancement when red tide plankton density is very high is limited, and more helpless for poisonous red tide.
The chemical method kind is a lot, by its mechanism of action, can be divided into the method for directly killing, the flocculation agent precipitator method and natural mineral flocculence etc.Directly killing method is to use chemical agent directly to kill red tide plankton, chemical agent commonly used has copper sulfate, unslaked lime, potassium permanganate, clorox, hydrogen peroxide etc., the problem that exists is that the toxicity of chemical agent is high, can destroy safeguard of coast and marine ecological system, be subjected to the impact of trend and diffusion short to the action time of red tide plankton, cost is high.Multiple organic algicide has good inhibition to red tide plankton, and also very little on the impact of non-red tide plankton, but exists quick-acting poor, and consumption is large, is subject to the shortcoming of the factor affecting such as trend and diffusion.The flocculation agent precipitator method are to utilize the colloid chemistry character of material, make the method for red tide plankton cohesion postprecipitation.Flocculation agent commonly used has inorganic flocculant, tensio-active agent and polymer coagulant, such as the ferro-aluminum compound etc.The action effect of flocculation agent is very obvious when red tide density is higher, and action time is short, and is less on the impact of non-red tide plankton, also can remove the suspended substance in the water body, purifies water.But molysite is the promotion material of red tide plankton, and aluminium salt has again certain contaminative, and cost also is the obstacle that the flocculation agent precipitator method are promoted.The natural mineral flocculence is mainly take clay mineral as main, aspect the impact of the marine eco-environment and non-red tide plankton, has obvious advantage, but the sol property of the method is poor, the ability of cohesion red tide plankton is low, consumption is difficult to eliminate red tide plankton when few, cause again the sludge amount excessive when consumption is large, very large on the impact of the epibiota ecosystem after the precipitation.
Biological process is the natural viral infection red tide algae of utilize purifying, and then utilizes it to the deactivation of red tide algae and the Degradation of algae toxin is made the eubiosis of marine eco-environment stable for extended periods of time, reaches the purpose of prevention and control red tide.But this method only has restraining effect to distinctive red tide algae, and also there is the risk that infects the sea farming biology in part virus.
Red tide has sudden, and the speed that red tide plankton increases during generation is exceedingly fast, and very big to the environmental damage of cultivation marine ecosystem, this has quick-acting with regard to the method that requires to kill red tide plankton.High-level oxidation technology prevention and control Disaster And Prevention Measures of Red Tides is a kind of method that newly-developed gets up, and therefore the method has oxidizing potential height (〉 2.8V owing to be oxidized to core with the representative hydroxy radical qiao of high-level oxidation technology), the fast (reaction rate constant 10 of speed of response
9L/mols), remaining hydroxy radical qiao is decomposed into oxygen and water, without the advantage of the Harmful Residue, has the unrivaled advantage of ordinary method aspect the invasion and attack of prevention and control Disaster And Prevention Measures of Red Tides.What Dalian Maritime University's employing was produced in real time kills red tide plankton and bacterium (utility model patent: a kind of device of controlling red tides by using active oxygen particles take hydroxy radical qiao as main active oxygen radical spray solution, patent No. ZL201020617592.9), it is biological not only effectively to have killed marine red tide, also improve significantly the dissolved oxygen amount of seawater, improved the water quality in red tide generation marine site.But because the method and device adopt spray pattern to kill red tide plankton, be subject to the impact of sea tide and diffusion, the utilization ratio of oxygen active particles is also low, the generation of hydroxy radical qiao is also very low, do not carry out the apparatus and method design for characteristics and the demand in cultivation marine site simultaneously, the effect of therefore processing for the invasion and attack of prevention and control mariculture district red tide plankton is restricted.If a small amount of hydrogen peroxide is incorporated in the active oxygen radical generating unit, can greatly improve generation concentration and the generation efficiency of hydroxy radical qiao, utilizing the special fence with luminescent material will cultivate marine site and red tide when simultaneously suffering the red tide plankton invasion and attack in the cultivation marine site may attack the marine site and isolate, and red tide plankton invasion and attack direction is laid active oxygen radical diffusion pipeline under the sea, to reduce the impact of sea tide and invalid diffusion, and then for the invasion and attack of mariculture district opposing red tide plankton provide special method and apparatus, reduce financial loss and ecological damage that marine red tide invasion and attack mariculture district causes.
