一种湖面蓝藻绿藻污染水体净化处理方法
By using a three-layer microcapsule water purifier and Vallisneria natans to colonize the plant, the Fe2+ concentration in the water is synergistically regulated, solving the problems of uneven treatment and large ecological disturbance in the management of cyanobacteria and green algae, and achieving the effects of rapid algae suppression and long-term ecological restoration.

AI Technical Summary
Existing technologies for controlling cyanobacteria and green algae suffer from problems such as fragmented treatment methods, poor emergency response capabilities, and weak ecological sustainability, making it difficult to achieve a balance between short-term control and long-term ecological regulation.
The microcapsule water purifier uses a three-layer structure, including a core of humic acid and cerium nitrate, an intermediate coating layer of carboxymethyl chitosan-tannic acid-trivalent iron, and an outer shell of eggshell powder mineralization. It is applied by drone and manually, and combined with the planting of Vallisneria natans, to regulate the Fe2+ concentration in the water and achieve multiple synergistic purification functions.
It achieves rapid inhibition of cyanobacterial physiological metabolism, long-term inhibition of algal growth, reduction of algal bloom risk, and promotes the transformation of aquatic ecosystem from algae-dominated to aquatic plant-dominated, with significant ecological benefits and environmental safety.
