Embodiment 1

[0028] First, the mimosine powder is prepared into a mother solution with a concentration of 1mg / ml with BG11 medium, and the final concentration of 40mg / L is added to the algae liquid of Microcystis aeruginosa, placed in a light incubator, and the culture temperature 30 (±1) ℃, light cycle 12 h: 12 h (12 hours light, 12 hours dark), light intensity 2000 lx, static culture for 7 days, the algae removal rate can reach 93.85%.

Embodiment 2

[0030] According to the method of Example 1, the dosage of mimosine was changed to 60 mg / L, and the algae removal rate could reach 99.35%.

Embodiment 3

[0032] According to the method of Example 1, the dosage of mimosine was changed to 80 mg / L, and the algae removal rate could reach 100%.

Abstract

The invention provides a plant alkaloid algaecide and application thereof. The plant alkaloid algaecide is mainly composed of sensitive plant alkaloid. When in use, the plant alkaloid is added into a water body containing blue-green algae to be dispersed and dissolved according to the addition amount of 40-80mg / L, so that the effects of inhibiting and killing the algae are achieved. According to the invention, the plant alkaloid taking the mimosine as the main component is selected as the algaecide, so that the algaecide is environment-friendly, relatively high in algae removal rate and low in cost, and has economic value of large-scale popularization and utilization.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a plant alkaloid algaecide and its application. Background technique [0002] In recent years, with the rapid economic development, human activities have produced a large number of pollutants discharged into natural water bodies, including industrial and agricultural wastewater, domestic sewage, excessive feed, certain metal elements or organic substances, etc., resulting in an imbalance in the water body environment, a large amount of nitrogen, phosphorus When the water body temperature, light and other climatic factors are in suitable conditions, it will lead to frequent occurrence of cyanobacteria blooms, resulting in the decline of biodiversity, the demise of submerged plants, and the outbreak of cyanobacteria blooms. An unusual response from the series ecosystem. [0003] How to effectively control the growth of algae in eutrophic water bodies and prevent the occurr...
