[0032] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0033] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0034] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0035] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] The algal samples to be tested were irradiated with this ultraviolet lamp irradiation experimental device for 1 minute, 3 minutes, and 5 minutes, and samples were taken sequentially for analysis. The specific detection method was as follows: Qualitative and quantitative analysis was performed on the algal samples irradiated with this device for 1 minute, 3 minutes, and 5 minutes using traditional microscopic examination. First, Lugo reagent was added to the selected algal samples at a volume ratio of 1-1.5%. After standing for 24 hours, the supernatant was removed, and the remaining concentrated algal solution was quantified again. Then, 0.1 ml of the concentrated algal solution was taken and placed in a plankton counting frame for observation using a 10×40x microscope. The microscope was a Chongqing Aote BK5000-TR, equipped with a 3-megapixel high-definition digital camera, which could be connected to a computer to photograph the algae. For quantitative counting, five squares in the counting frame were randomly selected, and all algae in these five squares were photographed and counted. The number of algal cells in the sample was then calculated by volume conversion, completing the detection.
