Description
Technical Field
The invention relates to the technical field of marine ecological environment protection, in particular to a marine red tide disposal device and a marine red tide disposal system.
Background
With environmental changes such as global warming and sea water eutrophication, the frequency, intensity and range of red tide occurrence are all in an ascending trend worldwide (Zhan Huiling, rao Xiaozhen.2021. Hazard, cause and prevention of red tide [ J ]. Biological teaching, 46 (7): 66-68.). When the ocean red tide disaster has harm to the aspects of the ocean ecological environment, coastal economy, human health and the like and causes （WU D,CHEN J,HE X,et al． Distribution,partitioning,and seasonal variation of lipophilic marine algal toxins in aquatic environments of a typical semi-closed mariculture bay ［J］． Enviroment Pollution,2019,255: 113299.）. ocean red tide outbreaks, a large amount of CO 2 in the water body is consumed, so that the pH value of the water body is gradually increased, and the environment of the ocean water body is greatly changed; and moreover, a large amount of red tide algae gathers, so that the sea surface is shielded, peculiar smell is generated, the survival of marine organisms is influenced, and the coastal travel experience is reduced. In recent years, ocean red tides in China frequently occur and have a near-shore development trend, and no disposal device which is effective in disposal, rapid in mobilization, economically feasible and ecologically friendly is available for the disposal of the red tides at present.
Currently, there are some chemical and physical methods applied to ocean red tide disposal: (1) The chemical method mainly adopts algaecide, strong oxidant, artificial chemical substance and tencel extract to directly kill red tide organisms; or adopting a coagulant precipitation method and a natural mineral flocculation method to adhere red tide for precipitation and disinfection. The chemical method is mainly applied to spraying substances by a mobile manned ship, and has the characteristic of quick response, but the direct addition of substances such as medicaments in seawater can have a certain influence on the ecological environment. The physical method (2) mainly adopts a grating method, an air curtain method and the like. The physical method is mainly applied to fixed devices such as grids, and has small influence on the ecological environment, but the operation influence range of the method is limited because the physical method is fixed. Compared with the fixed type, the mobile red tide disposal device is more beneficial to emergency work in the face of uncertainty of red tide explosion time and sea area.
The prior literature shows that the ultraviolet radiation and the photocatalyst have certain disinfection effect on marine algae. Liu Che et al (Liu Che, liu Wenjun. Research on the inactivation effect of UV-C on several marine microalgae, marine environmental science [ J ],2013,32 (2): 171-174.) UV-C ultraviolet radiation was performed on 8 common unicellular microalgae, and experiments found that ultraviolet has a certain inactivation effect on Phaeodactylum tricornutum, skeletonema costatum, dunaliella salina, protophaemale Lithospermum and Isodon akabaga. The Chinese patent with publication number of CN111994992A provides a method for killing red tide algae by using a supported composite photocatalyst, which is characterized in that graphite-phase carbon nitride/nano titanium dioxide composite photocatalyst is placed in red tide algae suspension, a visible light source is turned on to kill red tide algae, and the photocatalyst is proved to have a promoting and killing effect on sea red tide algae such as Karenia miq, skeletonema costatum and red tide Isopenaeus, and the method is green and has no ecological pollution. The above data results are limited to laboratory levels and are not practiced in real sea conditions. Moreover, treatment equipment for early treatment can be inserted in time before and at the beginning of red tide explosion, and no movable, automatic and green ocean red tide treatment device exists in the current market.
