Description
Technical field
The utility model relates to the blue-green alga bloom results, more specifically relates to a kind of device of harvesting water bloom blue algae.
Background technology
In recent years, because industrial boom, population increase, urbanization increases the weight of, severe environmental pollution, the eutrophication degree aggravation of the many water bodys of China, cause a large amount of breedings of algae, particularly blue-green algae, some water body even serious blue-green alga bloom takes place, but the quality and the availability of water body directly influenced, and endangering livestock and human beings'health.Middle and lower reach of Yangtze River area lake blue algae wawter bloom occur in for 4-October in a large number, especially in the generation maximum of the high temperature season blue-green alga bloom in 7-September.The a large amount of bloom blue algaes that take place of water body such as lake, reservoir are serious environment pollution, harm drinking-water water source on the one hand, has brought great influence to tourism on the other hand.For alleviating the pollution in lake, eliminate the blue-green algae peculiar smell, be necessary the blue-green alga bloom of bulk deposition is removed effectively.Removing blue-green algae has methods such as chemistry, biology and physics, and the sampling chemical process is thrown in pharmaceutical chemicals or reagent in the lake, must bring in various degree harm to water quality; Biological method is removed blue-green alga bloom and is not had the chemical pollution problem, but throw in filter-feeding fish and weed eater and microorganism etc. in a large number in the lake, though can remove a large amount of blue-green alga blooms, but at the peak season that blue-green algae breaks out in a large number, these methods are difficult to the blue-green alga bloom of bulk deposition is effectively eaten.Physics method has several different methods such as mechanical removal, biological explosion gas, and the sampling mechanical means is removed blue-green alga bloom, has not both had the such influence of chemistry and biology method, and can directly sweep off the lake surface blue-green alga bloom.Therefore, take place season in a large number at blue-green alga bloom, the method for employing machinery is removed effectively the blue-green alga bloom of bulk deposition and is used, to prevent to worsen propagation and secondary pollution, and reduce the water nutrition level thus, be very necessary thereby can reach the purpose of improving environment.Domestic have Jiangsu in Taihu Lake, Anhui in Chaohu, Kunming all attempts in the Dian Chi bloom blue algae is gathered in the crops, they have dropped into very big fund and manpower and have gathered in the crops, but can only obtain the algae slurry, effect is not very good.External also few about the reported in literature of results lake algae, have only Japan in an academic discussion, to deliver one piece of paper about the blue-green alga bloom results, its main technique route is that to utilize ship that algae is extracted in the whizzer on the ship with water pump centrifugal, then with fuel with the algae burn processing.What Japan, Korea S adopted is this cover technology basically.This method complicated operation, the cost height, consumes energy is quite big, and incendiary smog has caused pollution again to atmosphere, thereby also not very good.
