Description
Technical field
The invention belongs to gas ionization discharge, plasma chemistry and water environment protection technical field, relate to a kind of device for the treatment of red tide by strong oxidative free radical.
Background technology
Calendar year 2001, red tide takes place 77 times in Chinese marine site altogether, and cumulative area reaches 15000km
2, increased by 49 times than 2000, increase area 5000km
2Red tide was found 79 times altogether in China marine site in 2002, and cumulative area surpasses 10000km
2The big area red tide mainly concentrates on the offshore sea waters of the East Sea, the Bohai Sea and the Huanghai Sea.Main red tide plankton kind, total degree and cumulative area are than increasing considerably last one year.The red tide big area frequently takes place, and Chinese Environment of Alongshore Sea Area quality has been revealed red card, and worldwide oceanic resources utilization and marine economy have been caused serious negative impact.Very slow at improvement red tide progress of research both at home and abroad, when red tide occurred, people were in passive situation at a loss what to do basically.
At present, many both at home and abroad scholars have carried out a large amount of medicaments and have killed the research work of administering red tide with condensing method.Has only CuSO
4Done experimental study work with the clay flocculating method in natural marine site.Existingly in problem be: (1) medicament, flocculation agent consumption are excessive, the cost height, and toxicity is big, has secondary pollution, has destroyed the coastal waters ecosystem; Flocculate precipitate has considerable influence to bottom-dwelling, other marine organisms of long-term hazards; (2) medicament or flocculation agent clearance are not too high, and they can not decompose in seawater, disappear, and the red tide plankton of flocculating settling may dissociate after a few hours, swim again; (3) kill or the required overlong time of flocculating, usually at 20min-24h, owing to medicament or flocculation agent are subjected to sea beaten to dilute diffusion, concentration reduces significantly, is lower than to remove the necessary minimum concentration of red tide plankton, does not reach the purpose of administering red tide.Up to the present, domestic and international tens kinds of proposing are administered the device and methods of red tides, are in the exploratory stage of laboratory study mostly, can really be put to administer the very few of marine red tide, still do not have the improvement that the ideal device is used for marine red tide so far.
