Problems solved by technology

However, some cyanobacteria cause eutrophic seawater "red tide" and lake "bloom" after being polluted by nitrogen, phosphorus and other elements, which bring serious harm to fishery and aquaculture.

Embodiment 1

[0056] A cyanobacteria growth inhibitor, which comprises accounting for the total weight of the inhibitor:

[0057] 80% by weight of modified bentonite; and

[0058] 19 wt% terephthalates, and

[0059] 1wt% volatile oil of calamus calamus. The cyanobacteria growth inhibitor helps to inhibit the growth of cyanobacteria, which denatures the membrane protein of cyanobacteria, enhances the permeability of cells, leaks the contents of the cells, loses the function of cell division until the cells die, so as to achieve the purpose of inhibiting cyanobacteria; it can also inhibit the growth of cyanobacteria. Cause stress, promote the production of a large number of free radicals in cyanobacteria cells, and make the free radical scavenging system of cyanobacteria cells exceed the body's self-repair threshold, destroy cells, and finally inhibit the growth of cyanobacteria; inhibitors can also inhibit the tricarboxylic acid cycle of cyanobacteria cells, Thereby reducing the metabolic ...

Embodiment 2

[0072] A method for inhibiting the growth of cyanobacteria, comprising: adding terephthalic acid ester and volatile oil of calamus calamus into modified bentonite, and coupling treatment to inhibit the growth of cyanobacteria.

[0073] In the method for inhibiting the growth of cyanobacteria, the proportion of the modified bentonite is 98.99wt%, the proportion of the terephthalic acid ester is 1wt%, and the proportion of the volatile oil of Acorus calamus is 0.01wt%, The three together constitute a cyanobacterial growth inhibitor. The cyanobacteria growth inhibitor helps to inhibit the growth of cyanobacteria, which denatures the membrane protein of cyanobacteria, enhances the permeability of cells, leaks the contents of the cells, loses the function of cell division until the cells die, so as to achieve the purpose of inhibiting cyanobacteria; it can also inhibit the growth of cyanobacteria. Cause stress, promote the production of a large number of free radicals in cyanobacte...

Embodiment 3

[0100] A cyanobacteria growth inhibitor, which comprises accounting for the total weight of the inhibitor:

[0101] 95% by weight modified bentonite; and

[0102] 4.5% by weight of terephthalates, and

[0103] 0.5wt% volatile oil of Acorus calamus. The cyanobacteria growth inhibitor helps to inhibit the growth of cyanobacteria, which denatures the membrane protein of cyanobacteria, enhances the permeability of cells, leaks the contents of the cells, loses the function of cell division until the cells die, so as to achieve the purpose of inhibiting cyanobacteria; it can also inhibit the growth of cyanobacteria. Cause stress, promote the production of a large number of free radicals in cyanobacteria cells, and make the free radical scavenging system of cyanobacteria cells exceed the body's self-repair threshold, destroy cells, and finally inhibit the growth of cyanobacteria; inhibitors can also inhibit the tricarboxylic acid cycle of cyanobacteria cells, Thereby reducing the m...

Abstract

The invention provides a blue-green algae growth inhibitor, and belongs to the technical field of water pollution treatment. The growth inhibitor includes modified bentonite which accounts for 80 to 99% by weight of the total weight of the inhibitor, terephthalate which accounts for 1 to 19% by weight of the total weight of the inhibitor, and rhizoma acori graminei volatile oil which accounts for0.01 to 1% by weight of the total weight of the inhibitor. A method for inhibiting the growth of blue-green algae is also provided. The method includes adding the terephthalate and the rhizoma acori graminei volatile oil in to the modified bentonite; and performing coupling processing to inhibit the growth of the blue-green algae. The inhibitor can achieve the purpose of inhibiting the growth of the blue-green algae through synergistic coupling effects from different angles such as blue-green algae membrane protein denaturation, Free radical stress and the secretion of inhibitory enzyme, so that the inhibitor is wide in source, simple in preparation, low in cost and easy to operate; and secondary pollution cannot be generated during using.

Description

technical field [0001] The invention belongs to the technical field of water pollution treatment, and in particular relates to a cyanobacteria growth inhibitor. Background technique [0002] Cyanobacteria, also known as blue-green algae, is a class of long evolutionary history, negative Gram staining, no flagella, chlorophyll a, but no chloroplast (different from eukaryotic algae), capable of producing Large unicellular prokaryotes that perform oxygenic photosynthesis. The difference from photosynthetic bacteria is that photosynthetic bacteria (Rhodospirillum) carry out relatively primitive photosynthetic phosphorylation, do not release oxygen during the reaction process, and are anaerobic organisms, while cyanobacteria can perform photosynthesis and release oxygen. Its development makes the entire earth's atmosphere develop from anaerobic state to aerobic state, thus giving birth to the evolution and development of all aerobic organisms. So far, more than 120 kinds of cya...
