Description
Technical field
The ultrasonic algal-removing boat of a kind of wawter bloom emergency processing of the present invention is applied to belong to the environmental technology field of blue-green algae in the removal waterhead area water body that utilizes ultrasonic cavitation technical security, economy because of eutrophication causes the processing that algal bloom causes environment water to pollute.
Background technology
In recent years,, make most of water body suffer in various degree pollution, Urban water supply is caused have a strong impact on because a large amount of sanitary sewages, trade effluent, agricultural fishing are herded entering of water.According to investigations, China has the drinking water source more than 90% to be polluted in 430 cities, causes the eutrophication of water body, causes financial loss to reach 37,700,000,000 yuan, and the obvious characteristics of eutrophication is exactly the excessive multiplication of algae, brings very big influence to water supply project.The removal of algae can be adopted diverse ways according to the raw water quality situation, generally can adopt physics method, chemical method, biological treatment and combination process method.Physics algae-removing method commonly used has: Microfilter method, air supporting method, direct filtration process, big gradient magnetic filter method, active carbon adsorption and ultrasonic algae removing etc.Chemical algae removing: be in the workflow that does not change existing water factory, need do not increase main equipment and structures, and economical and effective, simple and easy to do algae-removing method, algicide commonly used has chlorine, dioxide peroxide, ozone, potassium permanganate etc.Biological treatment: utilize to make attached to the microbial film on the carrier surface that the algae of oedema is adsorbed, decomposing oxidation, some algae also can be preyed on by protozoon on the microbial film and metazoan, and this method also has good effect to the removal of algae toxin.The algae toxin generally is present in the frustule body, when frustule death, break after the just stripping of algae toxin, in eutrophication water, the ratio showed increased of blue-green algae, and the also corresponding increase of malicious algae.Sewickley at pennsylvania, USA had broken out the water digestive tract diseases one time in 1976, and the blue-green algae in the drinking water source is likely morbific reason.In all fresh water algaes, the Microcystis aeruginosa in the blue-green algae is that toxicity is the strongest, harm is maximum, the widest a kind of algae of pollution range
[3]The combination process method: ozone-air supporting coupling technology, ozone-active carbon advanced treatment process, microbial film are handled with other treatment process couplings and are removed algae.Pre-ozonation, biological treatment, the coupling of charcoal absorption treatment process, this coupling technology and the combination of conventional water-purifying process are more perfect, effective water purification approach.This combination process can reach 100% to the clearance of chlorophyll α, colourity, turbidity, ammonia, organic clearance also all is better than two kinds of combination procesies introducing above.Algae removal technology is varied, and various algae-removing methods all have its relative merits, and at present increasing new technology and combination thereof just more and more come into one's own and develop, and ultrasonic technique is exactly one of them.
Ultrasonic technology is a kind of novel environmental technology that development in recent years is got up, and is called as the environmental friendliness technology.Utilizing the organic pollutant of chemical pollutant, especially difficult degradation in ultrasonic degradation (sonolysis) water, is the novel water technology that development in recent years is got up.Ultrasonic wave is meant that higher (＞16kHz) elastic wave, large amplitude ultrasonic wave (low frequency) concentration of energy can make medium produce high vibration to the range of frequency that frequency ratio people ear may hear, is usually used in aspects such as ultrasonic cleaning, boring, chemical treatment, emulsification.In recent years, the ultrasonic applications that begins one's study both at home and abroad especially to the improvement research of hardly degraded organic substance in the waste water, has obtained certain achievement in water treatment, along with acoustochemical birth and development, ultrasonic wave comes into one's own gradually to organic degraded and has obtained extensive studies.Ultrasonic wave is made of the compressional wave of a series of density interphases, and by liquid medium to around propagate.When acoustic energy was enough high, in the loose semi-period, the intermolecular magnetism of liquid phase was broken, and formed cavitation nucleus.The life-span of cavitation nucleus is about 0.1 μ s, and it can produce localized hyperthermia's hyperbaric environment of about 400K and 100MPa in the moment of blast
], and the microjet of the about 400km/h of generation speed with intense impact power, this phenomenon is called ultrasonic cavitation.These conditions are enough to make organism that chemical bond rupture, water burning (aqueous combustion), pyrolytic decomposition (pyrolysis) or free radical reaction take place in cavitation bubble.Algae mechanism is killed in the ultrasonic wave algal control to be had: destroy cell walls, destroy gas vacuole, destroy organized enzyme.High-intensity ultrasonic energy destroys biological cell wall, and intracellular matter is flowed out, and this point is in industrial utilization.The special tectonic of alga cells is that cell paste contains many group gas vacuoles, the up-and-down movement of gas vacuole control alga cells.The shockwave that ultrasonic wave causes, jet, radiation pressure etc. can destroy gas vacuole.Under suitable frequency, gas vacuole becomes cavitation bubble and breaks; Simultaneously, the High Temperature High Pressure that cavitation produces and a large amount of free radical can destroy organized enzyme and active substance in the frustule, thereby influence the cells physiological biochemical activity.In addition, the chemical effect of ultrasonic wave initiation also can be divided Gigartina mamillosa toxin and frustule secretory product and meta-bolites.
Along with increasing the weight of of the seriousness of environmental pollution, studied a variety of treatment processs now, but the whole bag of tricks all there are some shortcomings more or less.Also need to develop more feasible more economical method in actual applications.Ultrasonicly integrate multiple water treatment technology such as advanced oxidation, burning, supercritical oxidation as a kind of new form of energy; disposable input, easy and simple to handle, safe in utilization, efficient is high, persistence is strong; very helping environment protection, therefore is a kind of method of very promising water treatment.Supersound process also has the characteristics of using the bigger effect of performance with other treatment process together.Both at home and abroad the report of ultrasonic wave algae removal also is not a lot, but its relevant research still is many, and this has increased the possibility and the feasibility of ultrasonic wave algae removal greatly, thus its should be after one of the algae removal method of primary study.
Now, the device of international ultrasonic wave algae removal mainly contains: LG Sound Sonic algae removal instrument, Water﹠amp; The Waterman algae removal instrument of Soil Management Associates, the algae removal device that Sonic Solutions LLC.com provides, Daniel Smith and Associates, the Ultrasonic leak detectorsand stethoscopes that LLC provides, hand-held units etc.
