摘要 低碳氮比(C/N)污废水中碳源不足,常会导致污水中生物反硝化不充分,继而引发硝酸盐大量积累的问题。农业废弃物玉米芯具有价格低廉、来源广泛及生物可降解性良好等优势,其经过适当处理可提高释碳量,在水环境污染处理领域中具有一定的应用潜力。本文综述了玉米芯的释碳过程、影响因素和预处理技术,以及在低碳氮比污废水处理过程中的应用,并针对目前研究应用中存在的问题,提出开展精确计算玉米芯在生物反应器中的投放量、玉米芯耦合其他材料联用技术、其他杂质离子对玉米芯释碳的影响机理、环境友好型玉米芯预处理化学药剂的研发、玉米芯在不同盐度海水养殖废水中的应用及玉米芯作为载体形成生物膜的机理等未来重点研究方向,以期为玉米芯的广泛资源化利用提供科学参考。

Abstract: Low carbon-nitrogen ratio (C/N) often leads to insufficient biological denitrification and nitrate accumulation in wastewater treatment process. As a kind of agricultural waste, corncob has many advantages, such as low cost, a wide range of sources and good biodegradability. Notably, the carbon release amount of corncob can be improved after proper treatment. Hence, corncob has a certain application potential in the field of wastewater treatment. This paper summarized the research progress of carbon release process, influencing factors, pretreatment methods, and the application of corncob in the treatment wastewater with low C/N. In order to improve the extensive resource utilization of corncob, some proposals were suggested, including accurate dose of corncob in bioreactor, combination of corncob with other materials, the impact and mechanism of other impurity ions on corncob carbon release process, environmentally friendly corncob pretreatment chemicals, the application of corncob in mariculture wastewater treatment, and the mechanism of biofilm formed on the surface of corncob.
