由上所列显微镜图像可知玉米淀粉颗粒为圆形、椭圆形或呈多角形,轮廓清晰，

From the microscope images listed above, it can be seen that the corn starch particles are round, elliptical or polygonal, with a clear outline and a dispersed and isolated state. , The particles have different shapes and sizes, there are obvious traces of connection between the particles in the mesh part, the starch particles no longer have sharp edges and corners, there are signs of wrapping and winding on the outer surface, the irregularity increases, which is beneficial to bridging flocculation and net catching The sweeping effect may be the result of modification, and adding coagulant chitosan, activated carbon, kaolin to it indicates that it has adsorption capacity and may have strong adsorption capacity.

由上所列显微镜图像可知玉米淀粉颗粒为圆形、椭圆形或呈多角形,轮廓清晰，呈分散孤立状态，本改性淀粉絮凝剂为空心孔状晶体结构，为大小不一的不规则形状，颗粒具有不同的形状和大小，目部分颗粒之间有明显连接的痕迹，淀粉颗粒已无锐利棱角，外表面有包裹和缠绕的迹象，不规则程度增大，有利于架桥絮凝与网捕卷扫作用，这可能就是改性的结果，并向其中加入助凝剂壳聚糖、活性炭、高岭土，说明其有吸附能力且可能有较强的吸附能力。

It can be seen from the above microscopic images that the corn starch granules are round, elliptical or polygonal, The profile of the modified starch flocculant is clear and in a state of dispersion and isolation. The modified starch flocculant is a hollow porous crystal structure with irregular shapes of different sizes. The particles have different shapes and sizes. There are obvious traces of connection between some particles of the mesh. The starch particles have no sharp edges and corners, and there are signs of wrapping and winding on the surface. The degree of irregularity is increased, which is conducive to bridging flocculation and net catching and sweeping In addition, chitosan, activated carbon and kaolin are added to the coagulant, which indicates that it has adsorption capacity and may have strong adsorption capacity.<br>
