生物除磷的研究进展

Advances in Biological Phosphorus Removal

强化生物除磷工艺(厌氧/好氧工艺)已经在世界各地广泛应用,然而,在各地不同条件的运行过程中,成功和失败的记录均有大量报道。为解决此工艺的不稳定因素,近年来研究者对此工艺的机理作了大量的研究,包括主导微生物的鉴定,生化代谢途径的探讨以及数学模型的建立等。同时,有研究者发现,生物除磷可以在单级好氧工艺中实现,此发现可能开发出一种经济、简单的生物除磷工艺,即通过"一步氧化法"实现有机物与磷的同步去除,具有重要的意义。本文系统的总结了传统厌氧/好氧生物除磷工艺和单级好氧生物除磷工艺的最新研究进展,以期为工程技术人员提供参考。

The biological phosphorus removal process was implemented in many wastewater treatment plants worldwide.However,success and fail records were indeed reported at full-scale plants on numerous occasions under conditions.Recent studies in this field utilized a wide range of approaches to address this problem,from studying the microorganisms that were primarily responsible for or detrimental to this process to determine their biochemical pathways and developing mathematical models that facilitated better prediction of process performance.Simultaneously,it showed that biological phosphorus removal could be realized in sequencing batch reactor with single-stage oxic process.This phenomenon may form a potentially economical and simple strategy for the ＂one-step＂ removal of phosphorus and organic substrates from wastewater.The recent advances in traditional anaerobic/aerobic biological phosphorus removal process and biological phosphorus removal with single-stage oxic process were summarized in order to provide some references for engineering researchers.
