Background
The occurrence of the bloom is accompanied with a large amount of outbreaks of algae, and the effective removal of the algae is a direct way for controlling the scale of the bloom and reducing the harm of the bloom. Through long-term research and practice, three main algae removal technologies taking physics, chemistry and biology as means are formed. The chemical method is mainly a chemical killing method. The chemical killing method generally kills algae by adding a medicament to inhibit the physiological function of algae cells, destroy the structure of the algae cells and inactivate or even disintegrate the algae cells. The main agents include strong oxidant (liquid chlorine, hydrogen peroxide, ozone, potassium permanganate, etc.), copper sulfate, etc.
For example, chinese patent CN201510562535 discloses a chitosan-illite composite algicide, which is prepared by compounding chitosan and illite powder, so that the chitosan and illite powder are attached to an alga body, rapidly settle, and sink to the water bottom, thereby achieving the purpose of removing algae. Chinese patent CN201410581964 discloses an algicide based on Alternanthera philoxeroides, and particularly discloses an algicide consisting of HCl, powdery Alternanthera philoxeroides, expanded vermiculite and water. However, the above patents all use a large amount of high molecular compounds, the killing speed of these components on algae is slow, and in this process, under the stimulation of light, ultraviolet rays and the like in the environment, these high molecular components will decompose and lose efficacy, and the algae removal effect is poor. Moreover, since the polymer compound itself contains some nutrients, the killed algae adhere to these components and release the nutrients therein to further promote the growth of algae, and thus the problem of eutrophication cannot be fundamentally solved.
Furthermore, Chinese patent CN201610943189 discloses a Cu/TiO loaded natural zeolite2The algaecide adopts a certain content of natural zeolite loaded Cu/TiO2The algicide is prepared from components such as modified clay, rare earth lanthanum, polyacrylamide, potassium permanganate and the like, the copper ions are released by utilizing the load particles in the algicide, the aim of controlling and killing the algae in the water body is fulfilled, and meanwhile, the loaded TiO is utilized to load the copper ions2The decomposition of organic phosphorus under the illumination can realize more comprehensive algae removal effect. However, the preparation raw material and the preparation method are complicated, and complicated supported particles, modified clay and the like need to be prepared in advance, and the supported particles, the modified clay and the like also contain the potassium permanganate pairs with high activityThe environment causes indiscriminate damage.
In conclusion, the existing algaecide has low algae removal efficiency, and even can not radically solve the problem of algae removal. The algae removal timeliness is poor, the expected effect can be achieved after a long time, and the water area using the algae remover needs to be oxygenated and detoxified to avoid killing the organisms such as fish, frightened fish, crabs and the like in the water body by the algae remover.

The invention provides a high-efficiency algae remover, which comprises zinc salt and pigment, wherein the content of the zinc salt is 30-60 wt%.
The specific type of the zinc salt is not particularly limited in the present invention, and various types of zinc salts known to those skilled in the art may be selected, including, but not limited to, inorganic zinc salts and organic zinc salts.
Examples of inorganic zinc salts include, but are not limited to, zinc sulfate heptahydrate, and the like.
Examples of the organic zinc salt include, but are not limited to, alkanolamine zinc complexes, specifically triisopropanolamine zinc complex, triethanolamine zinc complex, tetra (triethanolamine) zinc, N-butyldiethanolamine zinc, N-dibutylethanolamine zinc, N-t-butoxycarbonyldiethanolamine zinc, N-dimethylethanolamine zinc, diisopropanolamine zinc, N-ethyldiethanolamine and the like.
Preferably, the zinc salt is zinc sulfate heptahydrate.
In some embodiments, the zinc sulfate heptahydrate is present in an amount of 30 to 60 wt%; further preferably, the content is 45-55 wt%; more preferably, the content is 48 to 52 wt%.
The specific type of the pigment in the present invention is not particularly limited, and various pigments known to those skilled in the art may be selected, including but not limited to brilliant blue. In some embodiments, the pigment is present in an amount no greater than 0.2 wt%; further preferably, the content thereof is not higher than 0.15 wt%; further preferably, the content thereof is 0.1 wt%. The applicant unexpectedly discovers that when a proper amount of pigment (particularly, the brilliant blue of the alatin) is added into the algicide provided by the invention, the algicide effect can be obviously improved, and the quick response time is facilitated, so that the algicide can achieve an obvious algae removal effect in a short time. The reason is probably that the addition of the pigment can change the wavelength of light irradiating the algae in the environment to a certain extent and influence the growth promoting effect of the light on the algae. On the other hand, due to a large number of sulfonic acid groups and other structures in the pigment structure, the pigment has a good adsorption effect on algae, promotes the attachment of high-activity ingredients in the algaecide to the algae, enables the high-activity ingredients to be in contact with the algae better, namely for a longer time, and accordingly effectively shortens the algae removal time and improves the algae removal efficiency.
In some embodiments, the algae removal agent further comprises 1-5 wt% of an auxiliary algae removal agent; the auxiliary algaecide is a thiazoline derivative; more preferably, the content of the thiazoline derivative is 3 to 5 wt%, and still more preferably, the content of the thiazoline derivative is 4 wt%. The thiazoline derivative is isothiazolinone, which can rapidly and irreversibly inhibit the growth of microbes after contacting the microbes, so that microbial cells die.
In some embodiments, the algae removal agent further comprises an antibiotic. The antibiotic in the invention refers to a class of secondary metabolites with anti-pathogen or other activities generated by microorganisms such as algae or higher animals and plants in the life process, and the metabolites can interfere the development function of other living cells. Under the synergistic action of zinc salt, pigment and thiazoline derivatives, the invention can accelerate the onset time of the algae remover by compounding with antibiotics with proper content.
In some embodiments, the antibiotic is selected from one or more of quinolone antibiotics, beta-lactam antibiotics, macrolides, aminoglycoside antibiotics; further preferably, the antibiotic is a derivative of lincomycin; further preferably, the lincomycin derivative is clindamycin hydrochloride

In some embodiments, the algae removal agent further comprises an algae extract. Under the premise of not influencing the algae removal performance of the algae remover, other components which are helpful for removing algae can be added, including but not limited to natural algae removers and the like, such as a methanol extract of grape leaves, a sweet wormwood herb extract, a peony root extract and the like.
The method of the present invention for removing algae is not particularly limited, and the raw materials for the preparation may be mixed with each other. The amount of the algaecide used in the present invention is not particularly limited, and can be adjusted by itself according to the application object, the size of the water area, and the like.
