Problems solved by technology

[0003] Betel nut has the effects of killing insects and eliminating stagnation, reducing qi, promoting water, and cutting off malaria. It is a commonly used drug for deworming and eliminating stagnation in traditional Chinese medicine, but its application in the field of harmful algae control has not been reported.

Embodiment 1

[0019] 3 grams of betel nut decoction pieces were soaked in 500 milliliters of deionized water for 15 days in an airtight bottle and then filtered, and 50 milliliters of the soaking solution was added to 100 milliliters of Microcystis aeruginosa culture fluid as a test group, and the initial algae cell density of the Microcystis aeruginosa culture fluid was 120×10 4 individual / ml. For the control group, 50 milliliters of deionized water was added to 100 milliliters of Microcystis aeruginosa culture medium. Both groups were cultured in light incubators. The experimental group and the control group were paralleled with 3 bottles in each group. Algae cell density was measured 1 day, 3 days, 5 days, 7 days, 9 days and 11 days after adding betel nut anaerobic soaking solution.

[0020] The algal cell density of the control group was 80-3600×10 4 individual / ml. Algae cell density changes with time as shown in Table 1 and figure 1 shown.

Embodiment 2

[0025] 3 grams of betel nut decoction pieces were soaked in 60 milliliters of deionized water for 15 days in an airtight bottle and then filtered, and 6 milliliters of the soaking solution was added to 100 milliliters of Microcystis aeruginosa culture fluid as a test group, and the initial algae cell density of the Microcystis aeruginosa culture fluid was 100×10 4 individual / ml. For the control group, 6 milliliters of deionized water was added to 100 milliliters of Microcystis aeruginosa culture medium. Both groups were cultured in light incubators. The experimental group and the control group were paralleled with 3 bottles in each group. Algae cell density was measured 1 day, 2 days, 3 days, 4 days and 5 days after adding betel nut anaerobic soaking solution. The algal cell density of the control group was 100-1360×10 4 individual / ml.

[0026] Algae cell density changes with time as shown in Table 2 and image 3 shown.

Abstract

The invention relates to application of betel palm serving as an alga suppressing material. In the invention, a betel palm extract is put into a water body in which algae grow to realize suppression of algae. The betel palm has the advantages of quick response, good alga suppressing effect, easiness for operating, high ecological safety and the like, and can be applied to suppression of algae in natural water bodies or artificial water bodies such as lakes, reservoirs, rivers, garden landscape water bodies, household landscape water bodies and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a method for controlling harmful algae in natural water bodies. Background technique [0002] At present, the methods of controlling harmful algae in water mainly include physical methods, chemical methods and biological methods. Physical methods can directly remove algae in water bodies without secondary pollution; however, they require expensive operating costs and a large workload. The chemical method is quick and effective; however, due to the possibility of secondary pollution, the ecological impact on the water environment is not easy to determine, and long-term use will cause pollution to the ecological environment of the water body. Biological methods have good ecological security, but they are often slow to take effect and last for a long time. [0003] Betel nut has the effects of killing insects and eliminating stagnation, lowering qi, promoting water, and cutti...
