Problems solved by technology

Although this type of algicide has a significant effect, because copper ions will kill harmful algae and other aquatic plants and animals in the water body, the aquatic ecological environment will be destroyed and the ecological regulation function will be lost; and copper ions in the water body It cannot be degraded naturally, and it is easy to affect the ecosystem under the transmission of the food chain, and the bioaccumulation effect leads to the higher concentration of copper ions accumulated in organisms with higher trophic levels. Therefore, if humans eat aquatic animals with high concentrations of copper accumulated in their bodies , health will be seriously endangered

Embodiment 1

[0011] 175 grams of reed bamboo were chopped into about 5 cm plant segments, and then soaked in 500 ml of deionized water for 4 days and then filtered. Take extract 0, 6.67, 20, 33.3 milliliters and add in 200 milliliters Microcystis aeruginosa culture fluid, the inhibition result is as follows figure 1 As shown, after culturing for 1 day, the inhibition rates were 0%, 54.2%, 49.8%, and 61.8%, respectively. It can be found that the inhibition rate of algae growth reached more than 50% when the extract was added. After 7 days of culture, the inhibition rates were 0%, 79.2%, 91.9%, 95.5%.

Embodiment 2

[0013] 0.70 kg of reed bamboo was chopped into about 4 cm plant sections, and then extracted with 2 liters of ethanol for 24 hours, and then 6.67 ml of the obtained extract was added to 200 ml of chlorella culture medium, and the density of algae was only 57.3% of the control group after 1 day , that is, the inhibition rate was 42.7%; the density of Tianhou algae was only 19.1% of that of the control group, that is, the inhibition rate was 80.9%;

[0014] 0.70 kg of reed bamboo was chopped into about 4 cm plant sections, and then extracted with 5 liters of ethanol for 24 hours, and then 6.67 ml of the obtained extract was added to 200 ml of chlorella culture medium, and the density of algae was only 78.2% of the control group after 1 day , that is, the inhibition rate was 21.8%; after 7 days, the algae density was only 35.6% of that of the control group, that is, the inhibition rate was 64.4%.

Abstract

The invention discloses an algae inhibiting method of donaxine plant in the pollution water control domain, which comprises the following steps: 1) extracting the algae inhibiting material in the donaxine plant by water and organic solvent; 2) loading the chopped bundle of donaxine plant or donaxine in the bag; placing the bag in the disposed water. The invention is fit for lake, reservoir, river, landscape aquifer, domestic fish pond, aquarium, miscellaneous natural aquifer and artificial aquifer, which avoids secondary pollution and aquifer landscape influenced by a great amount of the doted organics in the water.

Description

technical field [0001] The invention belongs to the field of water pollution control, and relates to a method for effectively inhibiting algae in natural water bodies or artificial water bodies as a new algae-inhibiting material after treating reed bamboo plants. The applicable water types of the present invention include various natural water bodies and artificial water bodies such as lakes, reservoirs, rivers, park landscape water bodies, family landscape water bodies, or family fish ponds and fish tanks. Background technique [0002] The eutrophication of the water body caused by excessive nutrients such as nitrogen and phosphorus in the water body is an important reason for the deterioration of the water environment. In eutrophic water bodies, algae can easily grow explosively to form algae blooms or red tides, threatening the ecological environment of water bodies, endangering drinking water sources, destroying tourism landscape industries, and endangering aquaculture a...
