The invention belongs to the technical field of polymer adsorption materials, and particularly discloses a method and a device for preparing modified sponge with high amino content, and algae removal application. A uniform reaction liquid thin layer is formed on the surface of the sponge, and polyethyleneimine and an epoxy cross-linking agent in the thin layer are cross-linked under a mild condition, so that a layer of stable and uniform polyethyleneimine-epoxy cross-linking agent is formed on the surface of the sponge. The modified sponge is high in amino content, environment-friendly and low in sponge modification cost, and due to the special structure of the sponge, the modified sponge has a good prospect in the application field. The algae removal speed is high, the algae removal effect is good, and recycling and regeneration are easy. 本发明属于高分子吸附材料技术领域，具体公开了一种制备高胺基含量的改性海绵的方法和装置及除藻应用。本发明在海绵表面形成一层均匀的反应液薄层，在温和条件下薄层内的聚乙烯亚胺和环氧交联剂实现交联，从而在海绵表面形成一层稳定的均匀的聚乙烯亚胺-环氧交联物。这种改性海绵胺基含量高、环境友好、海绵改性成本低，再由于海绵的特殊结构，这种改性海绵在以上所述应
