This project focuses on the deeply treating of the pharmaceutical industry wastewater with high concentration, high toxicity, and the various types. The strategy to prepare the novel adsorbent/photocatalyst is investigated. In this project, based on renewable idea, a high specific surface graphene-like activated carbon is prepared from the waste poultry feather, and tantalates with high edge potential are selected as photocatalyst. According to the abundant keratins and disulfide bonds in the feather litter, tantalate is uniformly embedded in biochar grid by the strategies of self-assembly cross linking, biochar hydrothermal preparation, and high temperature activation. Meanwhile, nitrogen is also doped into carbon grid. Thus photocatalyst/feather biochar possess the highly redox ability, excellent absorption performance, well stability, and visible light responsive. We will build a green technological route for the preparation of the crosslinked semiconductor. Also we will investigate the methods about the controlled morphology and the surface modification. We will explore the mechanical model to improve synergistically the light adsorption ability, photocatalytic activity, and reusable stability. The competitive adsorption and degradation mechanism of pharmaceutical residues will be proposed. The prepared materials will be applied to the pretreatment of high concentration pharmaceutical sewage outlet through the simple transformation facilities. The concentration of antibiotics will be larger decreased to match with the level of the reliability and safety of drainage water treatment engineering. The results from this project provide valuable data accumulation and application demonstration for the administration of the industry wastewater in the field of the fine chemicals in Inner Mongolia Region.
