Embodiment Construction
[0007] Microbial membrane-hanging biological floating islands mainly use pioneer plants vetiver and chrysanthemum as floating island plants, and according to different regions and different waters, select some soil aquatic plants, such as water onions, cattails, calamus, iris, and parasols Bamboo, big drift, water hyacinth, canna, quince, water grass, water celery and properly domesticated flower plants. Before planting, the floating island plants should be domesticated and cultivated in the breeding base according to the plant habits, so that they can adapt to the growth of the target polluted water body and facilitate the formation of complex microbial films. Experiments have proved that pioneer plants have the strongest ability to absorb nitrogen, phosphorus, and heavy metals among aquatic plants, and are the preferred species for water purification. When the floating island plant seedlings grow to a height of 20cm, move them into the floating island soilless culture medium...
