光催化与生物降解直接耦合反应器内能质传递及转化过程实时测控与强化研究

In this project, we propose a novel way to perform the real-time measurement, collaborative regulation control and reinforcement for the processes of energy/mass transfer and transformation in the intimate coupling of photocatalysis and biodegradation (ICPB) reactor based on the new fiber technologies. The aim of the project is to overcome the bottleneck problems of measurement, regulation control and reinforcement of the energy/mass transfer and transformation in the ICPB reactor. The bottleneck problems are from the wastewater treatment and resource conversion employing the ICPB technology. In order to achieve the goal, the following works will be carried out. 1) To obtain the high efficiency photoelectric/photothermal conversion and photothermal radiation visible-light-driven photocatalytic optical fiber, first, we will investigate the principles and methods of the photoelectric/photothermal conversion and the photothermal radiation reinforcement; subsequently, we will explore the relationship between the photoelectric/photothermal conversion and photothermal radiation at fiber surface and internal light transmission of optical fiber. 2) We will study the principles and methods of real-time measurement, regulation control and reinforcement for the energy/mass transfer and conversion in the ICPB reactor. 3) We will explore the mechanism and rules of energy/mass transfer and conversion in the photocatalytic and biofilm areas, we will also reveal the coupling relationship between the photocatalysis and biofilm areas and their with the ICPB reactor in the processes of the energy/mass transfer and conversion. 4) We will establish the real-time measurement and control integration system for the ICPB reactor using the proposed fiber-optic on-line measurement systems and regulation control systems. 5) We will obtain the coordinated regulation control principles and methods for the processes of the energy/mass transfer and conversion in the ICPB reactor. According to the above studies, we can realize the real-time measurement, regulation control and reinforcement for the energy/mass transfer and conversion in the ICPB reactor, and the organic wastewater degradation and resource conversion of the ICPB reactor can be enhanced. Furthermore, the research results will promote the development of the engineering thermophysics and related interdisciplinary.
