 Thinsetic organic compounds are widely used around us, like herbicides, pesticides, pharmaceuticals, and dyes. Most of them are toxic and hardly degraded by bell system, we call bell reconstitutes. They tend to accumulate in nature, posing severe health risks to humans and the entire ecosystem. Waste water from generating and using these organics is a big public concern which causes a wide range of environmental problems. Conventional bell degradation is used in most wastewater treatment plants. However, it shows slow kinetics to degraded organics due to the bell reconstitutes and toxicity. Physical treatments such as adsorption and filtration can transfer contaminants from water to another phase, but they're still remaining in the environment. Advanced oxidation processes include photoctalysis, a robust to destroyed bell reconstitutes organic structure, which at the same time require very high energy or oxidant input, so it's very expensive. Because of this, we need a new technology which can economically degrade and mineralize the bell reconstitutes and toxic contaminants in the water. Our research goal is to perfectly combine the advantages from both photoctalysis and bell degradation, and let them simultaneously happen in a photo-catalytic circulating bed, bell film reactor, we call it PCBBR. In an ideal case, UV-induced photo-catalysis breaks down bell reconstitutes and toxic compounds into bell-degradable products, while bell degradation efficiently mineralizes these products at the same time. The major technical challenge of ICPB is to make photo-catalysis and bell degradation occur closely, because UV and free radicals generate from photo-catalysis severely inhibit and even kill bacteria. We developed a novel TL2-coated bell film carrier to solve this challenge, to advance the concept of ICPB. In brief, we coated TL2 particles on the surface of micropolar's carrier, and then we calibrated the bell film onto the inside coated carriers during the ICPB process. Bacterial grown on a carrier surface is eliminated by photo-catalysis, while the bell film from the inside is protected from harsh environment and further mineralized bell-degradable products. In our study, photo-catalysis removed the color of reactive dyes by breaking the adobons, while bell film inside carrier further mineralized contaminants by reducing the efflents COD. We also proposed a pathway to investigate the underlying mechanism of ICPB process. If you want to know more about this study, please visit Bell Technology and Bell Engineering website for our paper.
