摘要

摘要: 泥浆生物反应器技术可用于极端环境、高浓度污染土壤的修复,相比于其他生物修复技术具有处理效率高和环境条件易控制等优势。介绍了泥浆生物反应器对多环芳烃(PAHs)、多氯联苯(PCBs)、五氯酚(PCP)和总石油烃(TPH)等难降解有机物的处理效果,比较了污染物特性、降解途径、水土比和运行条件(pH、温度、溶氧量等)等因素对污染物去除效果的影响,综述了该技术的相关工艺、工程案例及应用成本。由于泥浆生物反应器综合应用成本较高、微生物修复过程复杂,目前国内的相关研究大多在实验室条件下进行。未来需进一步提升反应器修复效率,降低应用成本,推动泥浆生物反应器技术在国内的产业化应用。

Abstract: Slurry bioreactor can be applied in the remediation of high-concentration contaminated soils, and resist harsh condition by implementing oxygen and nutrients. It also shows advantages in high treatment efficiency and easy control of bioremediation process. This study introduced the removal ratios of non-biodegradable organics, i.e., polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), pentachlorophenol (PCP) and total petroleum hydrocarbons (TPH), by the slurry bioreactor. The effects of pollutants characteristics, biodegradation pathways, water-soil ratio and operational parameters (such as pH, temperature, dissolved oxygen, etc.) in the contaminants’ removal process were compared. The related techniques, engineering cases and application costs of slurry bioreactors were also reviewed. Due to its relevant high cost and complex biodegradation mechanisms, slurry bioreactor was mainly studied in the laboratory nowadays in China. As a promising bioremediation technology, it is necessary to further improve the treatment efficiency of slurry bioreactor and reduce the application cost in the future to promote the application.
