Background technology

China is the country of a serious water shortage, and gross amount of water resources does not enrich, and freshwater resources total amount is 2,800,000,000,000 m3, Occupy the 6th, the world, and the water resources quantity that can provide utilization per capita is about 900m3, only four points of world's water resources ownership per capita One of.More than 600 city, the whole nation there is more than 400 to there is insufficient water problem.In addition to water resource shortage problem, along with warp Ji and the development of society, China is gradually absorbed in serious water quality crisis, and water pollution problems has become China or even the world important One of ecological environment problem.The complex genesis of China Water pollution problem, large in number and widely distributed, pollutant kind is many, load is high, the most greatly The acute water degree of scarcity of China, and threaten the healthy of the public and living standard, cause huge economic society loss.

Show according to " China Environmental State Bulletin " of 2011, China the Changjiang river, the Yellow River, the Zhujiang River, Song Hua River, Huaihe River, sea River, the Liaohe River, Min Pian river, Zhejiang, the monitoring of the big water system in all rivers of south-west rivers and inland ten 469 states control sections in, I～III class, IV ～V class and bad V class water quality section ratio be respectively 61.0%, 25.3% and 13.7%.The water quality section ratio of 2012 is 68.9%, 20.9%, 10.2%.The water quality situation of 2013 compare 2012 without significant change, the water quality situation of 3 years is taken It is 67.2%, 21.8%, 11% that meansigma methods obtains section ratio.As can be seen here, the fresh water environment outstanding problem of China.

Equally, marine environment situation is the severeest.Immediate offshore area monitoring site represents area totally 281012 sq-km. Wherein, a class, two classes, three classes, four classes and bad four class sea water areas be respectively 64809 sq-kms, 120739 sq-kms, 39127 sq-kms, 18008 sq-kms and 38329 sq-kms.

Body eutrophication refers to owing to the increase of the nutritive salt such as Water phosphorus causes algae etc. hydrobiological in a large number Breeding, so that phenomenon (the Vol lenweider that Dissolved Oxygen in Water reduces, transparency declines, function of water body is destroyed Et al, 1982).The index characterizing body eutrophication has dissolved oxygen, carbon source and nutrient salts (nitrogen and phosphorus) etc..The most general The index used is: Water content is more than 0.2～0.3ppm, and Biochemical oxygen demand is more than 10ppm, phosphorus content more than 0.01～ 0.02ppm, in the fresh water of pH value 7～9, total number of bacteria every milliliter is more than 100,000, and the Chlorophyll-a Content characterizing amount of algae is big In 10 μm g/L.Body eutrophication often results in the growth of algae fulminant, formed wawter bloom or red tide (H.Kenneth et al, 2010) wawter bloom refers in the water body of eutrophication, the distorted proliferation of algae (especially cyanophyceae), some algae kind Biomass (generally more than 0.1mg/L) exceeds well over the phenomenon (Heisler, 2008) of the average level of other algae kind.Since 20th century, water body Eutrophication problem has become as the main Environmental Problems perplexing global numerous water bodys.According to investigations (Chorus et al, 1999； Smith et al, 2003), the lake of the Asian-Pacific area 54% is eutrophic state, and Europe, North America, South America and Africa are rich The ratio of nutrient laden is respectively 53%, 48%, 41% and 28%.Over nearly 20 years, China's lake eutrophication development speed is suitable Hurry up.The survey showed that, eutrophic lake number account for by investigation lake ratio by late 1970s to the eighties before The 41% of phase develops into the later stage eighties 61%, rises to again 77% to the later stage nineties 20th century, it is seen that China lake Fu Ying The development trend of fosterization is the severeest.

The direct result of storehouse, lake eutrophication is to cause the algae such as cyanophyceae, chlorella raised growth in water, ultimately forms red The phenomenons such as tide, wawter bloom, cause animals and plants in water dead because lacking illumination and oxygen, and aquatic ecosystem is destroyed.According to 2010 Year " China marine environmental quality publication " display, within 2010, annual full marine site finds red tide 69 times, and cumulative area 10892km2 is red Tide finds that number of times and 2009 (68 times) remain basically stable, but contrast 20 years China's offshore red tide generation frequencys in the past, hence it is evident that send out Existing last decade increases than the frequency that the nineties in 20th century occurs during the decade.The generation of red tide not only can produce danger to human health Evil, and the halobiontic breedings such as greater coasting area fish, shellfish can be affected, cause huge economic loss.Thus, to red tide, The improvement of the phenomenons such as wawter bloom and preventing and treating are to maintain and the important measures of protection water ecology balance.

When red tide, wawter bloom occur, algae is gathered in water body top layer in a large number, not only affects water landscape, and can hinder water The photosynthesis of raw plant, affects the exchange of oxygen between water-vapor interface, and the plankton in water body then can consume in a large number simultaneously Oxygen so that Dissolved Oxygen in Water drastically declines, ultimately result in organism in water such as Fish etc. because of anoxia death by suffocation, aquatile Kind reduces, aquatic ecosystem is disorderly, ornamental hydrophyte suffers destruction (Xu great Wei etc., 2007；Remaining water is brave, and 1999； Diego-McGlone et al, 2008).In addition a lot of algae also can produce Algae toxins, smell substance (soil raw meat element, mercaptan, Yin Diindyl, amine, ketone etc.) and the poisonous and harmful substance of other secondary metabolism, affect various aquatic and semi-aquatic animal or by food Thing chain transmission threaten the mankind health (Bury et al, 2007；Chorus et al, 1999), in 1996, Brazil just occurred One cause Algae toxins pollutes Rend dialysis water and causes the dead matters of aggravation (Azevedo et al, 2002) of 52 people.Also have one A little algae directly or indirectly produce serious threat to the healthy of the mankind, and WHO Report shows collection during breakout of water bloom Water sample 60% all contains toxin, and when in drinking water resource, algae density is more than 105/mL, the mankind will produce long-term disease (Bartram et al, 2003).

Present stage algae-removing method is broadly divided into three major types: physics is except algae, chemical algae removing, biology are except algae.Physical method is main Including following several: machinery removal method, ultraviolet irradiation, supersonic algae removing are sent out, gamma-rays irradiation, shading method, Filtration Deng, owing to machinery is emergent except algae except algae method is aimed at, it is impossible to accomplish pre-to prevent and kill off algae, expend a large amount of manpower physics simultaneously, economical Benefit is not calculated.Shading method, Filtration realize relatively difficult under field conditions (factors), and ultraviolet irradiation and gamma-rays irradiation are same Sample implements relatively difficult, and radiation simultaneously may bring pollution.And supersonic algae removing does not has secondary pollution to ecological environment, And except algae efficiency comparison is high, after deliberation, may be up to 68% by the ultrasound wave algal control rate of 6 days that frequency is 200kHZ, so ultrasonic Ripple can be used for, except algae, the best method that Hu Ku administers beyond doubt.

Chemical method includes adding medical method, clay flocculating method, preoxidation and activated carbon method etc., but it is to aquatic ecological Destruction bigger.Although the effect of activated carbon method is preferable, but because high cost is not suitable for using on a large scale.

Biological method includes aquatile method and water plant method two kinds, but all can cause other species invasion, finally breaks Bad ecological balance.
