Embodiment Construction

[0039] The method for biological prevention and control of bloom pollution in eutrophic water bodies of the present invention includes the following steps: according to the hydrological conditions and bloom conditions of the water body, natural plant algae inhibitors are sprayed on the water body, the components and mass percentages of the natural plant algae inhibitors It is: the algae inhibitor is 60%-80% of agrimony water extract, vitamin C 10-20%, amino acid 5-10%, citric acid 5-20%; in the water body is placed a plant for growing aquatic plants Biological floating island, the area of ​​biological floating island occupies 1 / 10-1 / 5 of the area of ​​the water body.

[0040] The above method was applied to the study on the emergency treatment of water bloom pollution in the Gaolan River, a tributary of the Three Gorges Reservoir area, and the field algae suppression experiment was carried out, and good results have been achieved. The specific implementation of the method is as f...

Abstract

The invention relates to a method for preventing and controlling water bloom pollution organisms in eutrophicated water body, which comprises the following step: according to the hydrological condition and water bloom condition of the water body, spraying natural plant algae inhibitor into the water body, wherein the natural plant algae inhibitor comprises the following components in percentage by mass: 60 to 80 percent of water leaching extract of hairyvein agrimonia herb and bud, 10 to 20 percent of vitamin C, 5 to 10 percent of amino acid and 5 to 20 percent of citric acid. The biological algae inhibitor used by the method is natural plant extract, can be biodegradable in a short period, and has the half-life period about 7 days proved by experiments, so the biological algae inhibitor cannot bring about secondary pollution to the environment, and dose not have post-treatment problem; moreover, the biological algae inhibitor has low price which is only dozens of yuan per kilogram, and is suitable for popularization and promotion.

Description

Technical field [0001] The invention relates to the field of environmental treatment of water bloom pollution, which is applied to water bloom prevention and control of freshwater eutrophic water bodies and ecological restoration of water bodies, and specifically relates to a biological control method for water bloom pollution of eutrophic water bodies. Background technique [0002] In recent years, due to the development of industrialization and the continuous intensification of human production activities, a large amount of organic matter has been continuously discharged into lakes and rivers and accumulated in them, resulting in eutrophication of lakes and rivers. The increasing eutrophication of water bodies has led to the proliferation of algae and the formation of increasingly serious water bloom pollution. The frequent occurrence of "water blooms" has greatly reduced the quality of water bodies, disrupted the balance of water ecosystems, and affected aquaculture. It has se...
