This work reports the details of the design components and materials used in a linear compound parabolic trough reactor constructed with an aim to use the photocatalyst for solar photocatalytic applications. A compound parabolic trough reactor has been designed and engineered to exploit both UV and visible part of the solar irradiation. The developed compound parabolic trough reactor could receive almost 88% of UV radiation along with a major part of visible radiation. The performance of the reactor has been evaluated in terms of degradation of a probe pollutant using the parameters such as rate constant, residence time and photonic efficiency. An attempt has been made to assess the performance in different ranges of solar spectrum. Finally the developed reactor has been employed for the photocatalytic treatment of a paper mill effluent using Degussa P25 as the photocatalyst. The paper mill effluent collected from Nagaon paper mill, Assam, India has been treated under both batch mode and continuous mode using Degussa P25 photocatalyst under artificial and natural solar radiation, respectively. The photocatalytic degradation kinetics of the paper mill effluent has been determined using the reduction in total organic carbon (TOC) values of the effluent.
这项工作报告了设计组件的详细信息和用于构建线性复合抛物面槽式反应器的材料，该反应器旨在将光催化剂用于太阳能光催化应用。设计并制造了一种复合抛物面槽式反应器，以利用太阳辐照的紫外线和可见光部分。所开发的复合抛物面槽式反应器可以接收近 88%的紫外线辐射以及大部分可见光辐射。根据降解探针污染物的速率常数、停留时间和光子效率等参数，评估了反应器的性能。还尝试在不同的太阳光谱范围内评估性能。最后，使用 Degussa P25 作为光催化剂，该反应器已用于处理造纸厂废水的光催化处理。使用 Degussa P25 光催化剂，分别在人工和自然太阳辐射下，以批处理和连续处理模式处理了从印度阿萨姆邦纳高恩造纸厂收集的造纸厂废水。通过废水总有机碳 (TOC) 值的降低来确定造纸厂废水的光催化降解动力学。
