摘要
The present invention proposes a composite material which can rapidly and effectively remove algae and transform them into submerged macrophytes. The composite material is a mixture of two functional materials: one can grow into submerged macrophytes, and the other is clays or modified local soil particles which can flocculate algae, inhibit phosphorus release from sediments and act as the carrier of the above-mentioned seeds, earthnuts, buds, and roots of submerged macrophytes. In addition, the present invention proposes a physical-chemical-ecological combined method for improving water quality and enhancing the ecological restoration of eutrophic lakes using the above-mentioned material. By spraying the composite material to the lake surface, the new method can remove algae and turbidity through flocculation and complete the planting process simultaneously so that HABs and eutrophication are effectively controlled.
