Abstract

The invention discloses a phytoremediation technology for polluted water. The technology comprises the following steps: (1) screening seeds with full particles, disinfecting with an ethanol solution,and cleaning the disinfected seeds with clear water; (2) treating the seeds with a colchicine solution, and drying the treated seeds in the shade at normal temperature; (3) treating the seeds with warm water, and soaking the seeds with the colchicine solution; (4) dibbling seeds in a container, and covering the seeds with soil; (5) placing an artificial floating island in the test section of the polluted water, fixing the container containing seeds on the artificial floating island, and covering the test section of the polluted water with a certain area; (6) carrying out maintenance management; and (7) completely harvesting the plants. The method has the following beneficial effects: the technology can improve the germination rate of plant seeds, induce the generation of plant polyploidy,accelerate the growth speed of plants, effectively improve the absorption and extraction capacity and remediation efficiency of copper ions and nutritive salt in polluted water and shorten the remediation period.

Description

technical field [0001] The invention relates to the technical field of polluted water treatment, in particular to a phytoremediation technique for polluted water. Background technique [0002] At present, the commonly used methods of water body restoration mainly include physical methods, chemical methods and ecological restoration methods; chemical methods mainly control the content of pollutants such as nitrogen, phosphorus, and copper ions in water by adding flocculants, coagulants, and algaecides. , has the advantages of simple operation, less dosage, quick effect, etc., but there are problems such as high cost, affecting the ecological environment, secondary pollution, etc.; physical methods are mainly controlled by methods such as dilution and flushing, aeration and oxygenation, physical adsorption, and sediment control The content of pollutants such as nitrogen, phosphorus, and copper ions in the water has a good treatment effect, but there are also problems such as l...
