摘要
太阳能杀菌处理创新方法可在家庭中实施,以解决水污染问题,尤其是那些由微生物引起的、可能导致水传播疾病的污染物。在审查期间,对当地水源的浑浊度和微生物质量进行了评估。结果发现,在旱季,河水的浊度低于 30 NTU(奈米浊度单位),而在雨季,河水的浊度通常高达 50 NTU。本综述旨在了解这些发现对当地及其技术背景的影响。这项研究探讨了如何利用太阳辐射来净化未经处理的水中的微生物。温度和开放时间是两个不同的正常因素。首先将微生物量为 40-55 (CFU) 的水置于温度高于 44.5 °C 的太阳辐射下,结果为 0 (CFU),开放时间为 6 小时。在 95% 的确定性信息范围内进行的事实检验的 P 值小于 0.0001。
Assessment of microbial water treatment by direct solar radiation disinfection approach
The solar sterilization treatment innovation method can be implemented within households to address water pollution, especially those contaminants caused by microorganisms that may lead to waterborne illnesses. During review, water sources in the local area were assessed for turbidity and microbial quality. It was found that river water had turbidity levels of less than 30 NTU (Nephelometric Turbidity Units) during the dry season and typically up to 50 NTU during the wet season. This review aimed to understand the impact of these findings on the local area and its technological context. This study researched the utilization of sun-based radiation to clean the microbial mass tracked down in untreated water. Temperature and length of the openness are the two normal factors that were distinguished. The first water with a microbial heap of 40–55 (CFU) was presented to solar radiation at a temperature of above 44.5 °C outcome 0 (CFU) at the openness season of 6 h. The size and kind of materials utilized for this process were PET bottles of 1.5 L capacity with a half-dark tone. The factual examination at a 95% certainty information stretch has a p-value of <0.0001.
