Effect test

Embodiment 1

[0038] The anti-algae activity of JSCD was verified by the algae-inhibiting circle test, and distilled water (negative control), 1mg / L CuSO 4 Solution (positive control) and 1% JSCD solution 200 μ L each, after light culture 48h, measure the diameter of algae inhibition circle, the algae inhibition effect is as follows: figure 1 as shown, figure 1 A is the negative control, B is the JSCD treatment, the diameter of the algae inhibition zone is 35mm, and the algae-dissolving effect is obviously better than figure 1 CuSO shown in C 4 treatment (the diameter of the algae inhibition circle is 25mm).

Embodiment 2

[0040] Add the algicide JSCD of the present invention into the liquid of artificially cultured Microcystis aeruginosa at a ratio of 1%, continue culturing for 24 hours, observe the transparency of the treated algae liquid and measure the content change of chlorophyll α. figure 2 Transparency rendering after JSCD processing, image 3 It is a graph of chlorophyll α content after JSCD treatment. The results shown in the figure show that after JSCD treatment, the algae liquid becomes clear, the chlorophyll α content decreases significantly, and the growth of algae cells is significantly inhibited. In the figure, ck is the blank control set up in the experiment.

Embodiment 3

[0042] Collect fresh cyanobacteria water samples from the cyanobacteria salvage point in Lujiangkou, Taihu Lake, Wuxi between August and September. After concentration, they are treated with JSCD at a dosage of 2%. After standing for 48 hours, the algicidal effect is observed, and the morphological changes of algae cells are observed by sampling microscope. . Such as Figure 4 As shown, after being treated with JSCD, the water samples of algae blooms in Taihu Lake became transparent and clear, and most of the algae sank. Microscopic observation showed that the algae cells ruptured after being treated with JSCD, and the cells were seriously damaged. Figure 5 Shown in B.

Abstract

The invention discloses an algaecide. The algaecide mainly comprises cinnamic aldehyde, eugenol and citric acid, wherein the content of the cinnamic aldehyde is between 0.01 and 5.0ml/l; the content of the eugenol is between 0.01 and 5.0ml/l; the mass content of the citric acid is between 1.0 and 5.0 percent; the content of azone is between 1.0 and 1.5 percent; and the content of NP-10 is between 8 and 15 percent. The algaecide has good algae-killing effect, wide range of pH application and convenient and safe use, cannot cause secondary pollution to the environment, has deodorizing effect, and can be widely applied to algae-killing and water purifying treatment for natural and landscape water bodies.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a preparation containing cinnamaldehyde, eugenol and citric acid for removing algae in natural, landscape water bodies and industrial water. Background technique [0002] Algicides are a common class of water treatment chemicals. The eutrophication of the water body leads to the overgrowth of algae in the water to form a "bloom", which reduces the transparency of the water body, causes a sharp drop in dissolved oxygen in the water, causes a large number of aquatic organisms such as fish to die, and even endangers human health. Landscape water bodies and industrial water are also affected by a large number of algae blooms, resulting in huge economic losses. At present, the removal methods of algae are mainly divided into physical methods, chemical methods and biological methods. Chemical methods have been widely used because of their advantages such as high al...
