一种铁碳微电解强化硫铁矿自养反硝化生物滤池装置及方法
By using iron-carbon micro-electrolysis to enhance the autotrophic denitrification biological filter device for pyrite, the problems of low denitrification efficiency caused by the instability of pyrite crystal structure and easy passivation of iron-carbon packing have been solved. This has enabled efficient and deep denitrification and phosphorus removal of wastewater with low carbon-to-nitrogen ratio, and improved the long-term operating performance and anti-clogging ability of the system.

Abstract
本发明公开了一种铁碳微电解强化硫铁矿自养反硝化生物滤池装置及方法，属于污水深度脱氮处理技术领域。该装置包括反应器主体、填料层、布水系统、氮气反冲洗系统及PLC控制系统。硫铁矿作为电子供体进行自养反硝化脱氮；铁碳微电解体系形成局部原电池，产生亚铁离子及活性氢，提高系统电子供给能力，反应生成的铁离子能够有效去除磷酸盐的同时加速硫铁矿表面电子迁移，提高硫铁矿中Fe‑S键断裂效率，从而提升硫铁矿电子释放能力，强化硝酸盐去除。氮气反冲系统能够有效地防止填料板结。本发明具有脱氮效率高、无需外加有机碳源、运行稳定及适用于低碳氮比污水深度脱氮除磷处理等优点。
