The invention discloses a method for detecting full-particle-size aquaculture wastewater micro-plastics through an ultraviolet visible light confocal Raman spectrum, and relates to the technical field of micro-plastic detection. The specific detection method comprises the following steps: (1) acquiring Raman spectrum data of a micro-plastic standard substance; (2) separating and screening suspected microplastics in the culture wastewater sample; (3) acquiring Raman spectrum data of suspected micro-plastics in the culture wastewater sample; and (4) identifying the suspected microplastics in the culture wastewater sample. The method provided by the invention has the characteristics of high sensitivity, high accuracy and strong anti-interference performance, and can accurately identify and quantify small-size and large-size micro-plastics. 本发明公开了一种紫外可见光共聚焦拉曼光谱检测全粒径水产养殖废水微塑料的方法，涉及微塑料检测技术领域。具体检测方法为：(1)微塑料标准品拉曼光谱数据的获取；(2)养殖废水样品中疑似微塑料的分离和筛选；(3)养殖废水样品中疑似微塑料拉曼光谱数据的获取；(4)养殖废水样品中疑似微塑料的鉴定。本发明方法具有灵敏度高、准确度高、抗干扰性强的特点，并能准确识别
