Description

Red tide algae removing agent based on tannin activated persulfate and application thereof
Technical Field
The invention relates to a method for treating seawater red tide pollution, in particular to a red tide algae algaecide based on tannin activated persulfate and application thereof.
Background
Red tide is an ecological abnormal phenomenon that some microalgae, protozoa or bacteria are explosively proliferated or gathered to a certain level under certain environmental conditions to cause water body discoloration or harm to other organisms in the ocean. In the marine system, microalgae play an important role not only in providing food to other aquatic organisms at the bottom of the food chain, but also in the global carbon cycle, and they absorb carbon dioxide from the atmosphere through photosynthesis, thereby performing a carbon sequestration effect. However, under certain conditions, certain species proliferate explosively and accumulate or produce toxins to form harmful algal blooms, which are generally called red tides because they cause the water to appear red. In recent years, the aforementioned Harmful ecological phenomena are collectively called Harmful Algal Bloms (HAB) by the international scientific community.
In recent years, as the level of carbon dioxide rises, the global climate becomes warm, and the eutrophication degree of water body becomes more and more serious, the occurrence scale and frequency of harmful algal blooms generally tend to increase year by year. The frequently-occurring harmful algal blooms not only can cause massive death of marine organisms to reduce the yield of marine fishery on a large scale, but also can indirectly influence human health through the enrichment of red tide toxins, and can break the dynamic balance of marine ecological environment. Since the 70 s of the 20 th century, more than 3000 red tide disasters occurred in coastal waters in China, and the economic loss caused by each year is as high as billions of RMB. Therefore, the prevention and control of red tide disasters are necessary for the development of marine ecology and human health in China. Because of the great harm of red tide to the economy and human health, the treatment measures of red tide have been the focus of attention and research. The method can be roughly divided into two research directions, wherein one research direction is to reduce the occurrence frequency of the red tide by early detection and early warning before the occurrence of the red tide disaster; the other is that after a disaster occurs, the influence area of the red tide is reduced by treating red tide organisms, so that the harm of the red tide is weakened, and the treatment measures can be roughly divided into a biological method, a physical method and a chemical method. The physical method is mainly to remove algae by using mechanical equipment and applying air flotation, ultrasonic waves, stirring, adsorption and the like; biological methods use zooplankton, macrophytes, microorganisms, and filter-feeding shellfish to inhibit or eliminate microalgae; the chemical method mainly comprises a medicament killing method and a flocculation method. The flocculation sedimentation method has prominent research results, and particularly, a great deal of research is carried out at home and abroad on the flocculation aspect of the modified clay. However, the method has certain defects, and the red tide removing biological capacities of different types of clay minerals and even the same type of clay minerals are greatly different; different application modes also significantly affect the ability of clay to remove red tide organisms; the key is that the cost of spreading a large amount of clay is high, the effect is slow, and secondary rebound is possible to cause pollution.
Tannin is also called tannin, is a polyphenol derivative, is widely present in plants, is safe and nontoxic, and has strong biological and pharmacological activities. The red tide algae is a natural product with important development and utilization values by obviously inhibiting the growth of the red tide algae through the degradation effect on the red tide algae, so the red tide algae is applied to the treatment of the red tide. Persulfate is a common oxidant and has a certain killing effect on algae cells, and because persulfate has the advantages of low toxicity, low price, easiness in operation and the like, the persulfate activated by the tannic acid is used as the red tide algaecide, so that the potential application value for removing red tide algae exists, but no relevant research report exists.

And because the invention is a homogeneous system, the problem that the seawater environment is turbid and the aquatic environment is influenced due to large input amount of the heterogeneous system is solved.
