preparation example Construction

[0015] The preparation method of the powdery solid is as follows: (1) weighing the above-mentioned medicines according to the ratio; (2) uniformly mixing the medicines together; (3) grinding the mixed medicines into powder.

[0016] An application method of an algae-inhibiting and algae-removing agent of the present invention comprises the following steps: preferably adding the powdery solid agent into the water body according to the following concentration range:

[0017] Polyaluminum Chloride: 4-8mg / L Diatomite: 18-26mg / L

[0018] Pyrogallic acid: 0.9—1.8mg / L Chelidonine: 0.5—1.1mg / L

Embodiment 1

[0020] In the light incubator (temperature: 28°C, light intensity: 40μE·m -2 ·s -1 ), cultured 500mL Microcystis aeruginosa liquid to make the algae density reach 1.0×10 7 per mL, when the algae density requirement is reached, add the algaecide prepared according to the ratio described below to make each component reach the corresponding concentration, and take this as the starting time of the reaction, and continue to place it in the light incubator. The reaction time is 24 hours, samples are taken at different reaction time intervals within 24 hours, and the algae density value is determined by electron microscope.

[0021] Its component and mass percentage content of described medicament are:

[0022] Polyaluminium Chloride 15% Diatomaceous Earth 80% Pyrogallic Acid 4% Chelenerythrine 1%

[0023] Prepare the medicament as a powdery solid, and the specific steps are: (1) weigh the above-mentioned medicines according to the stated ratios; (2) mix the medicines together; (3...

Embodiment 2

[0028] Put 8 bottles of 500mL Microcystis aeruginosa liquid in a light incubator (temperature: 28°C, light intensity: 40μE·m -2 ·s -1 ) culture, each two bottles as a group, so that the density of algae reached 0.5 × 10 7 pcs / mL, 1.0×10 7 pcs / mL, 1.5×10 7 pcs / mL, 2.0×10 7 individual / mL. When the algae density requirement is reached, add the algaecide prepared according to the ratio described below to make each component reach the corresponding concentration, and use this as the starting time of the reaction, and continue to place it in the light incubator for the next three During the month, samples were taken at different reaction time points at the same time, and the algae density value was determined by electron microscope.

[0029] Its component and mass percentage content of described medicament are:

[0030] Polyaluminium Chloride 25% Diatomaceous Earth 70% Pyrogallic Acid 3% Chelenerythrine 2%

[0031] Prepare the medicament as a powdery solid, and the specific s...

Abstract

The invention discloses an alga inhibiting and eliminating drug. The alga inhibiting and eliminating drug comprises, by mass, 15 to 25% of polymeric aluminum, 70 to 80% of diatomite, 3 to 5% of pyrogallic acid and 1 to 3% of chelerythrine. The alga inhibiting and eliminating drug has the following beneficial effects: (1) good effect and fast action; (2) small secondary pollution; and (3) long-lasting alga inhibiting effect.

Description

technical field [0001] The invention relates to the field of river course management, in particular to the use of a high-efficiency algae-inhibiting and algae-removing agent. Background technique [0002] The outbreak of toxic cyanobacteria bloom not only brings serious harm to the ecosystem, but also seriously threatens the healthy life of human beings. The use of chemical and biological agents in the process of algae suppression and algae removal is one of the most effective and commonly used techniques in the short term among many algae removal methods at this stage, and it is also a relatively well-researched algae removal method at home and abroad. In the study, the addition of various chemicals achieved the purpose of algae inhibition and algae removal to varying degrees, and also alleviated the impact of toxic algae blooms on the ecological environment and human health to a certain extent. In terms of the selection of algicides, how to achieve the multi-faceted requi...
