  • 摘要: 过程监测及调控是废水生物除磷工艺得以长期稳定运行的基础。为了获取氧利用速率（OUR）在生物除磷过程的潜在应用及该过程氧利用特性，开展聚磷菌好氧吸磷过程的呼吸测量实验，分析了OUR曲线变化与磷酸盐浓度变化、胞内聚合物（PHAs）氧化、外源COD存在与否与浓度变化及pH变化之间的响应关系。研究得到如下结果：富集污泥无磷酸盐存在时，体系依然存在明显的氧利用行为，在不吸磷的情况下聚磷菌胞内的PHAs依然会好氧氧化；外源COD的存在将改变PAOs吸磷速率并延长好氧吸磷的结束时间；体系初始pH的不同导致好氧吸磷效率、吸磷过程pH变化趋势及变化程度的不同；不同的初始条件得到不同的OUR。分析证实，利用测量OUR来监测聚磷菌好氧吸磷过程的运行状态是可行的。
    Abstract: Process monitoring and regulation are the basis of long-term stability in wastewater biological phosphorus removal processes.To determine the characteristics of oxygen uptake and potential application of process monitoring in wastewater biological phosphorus removal,respiratory measurement experiments of the absorption of phosphorus by PAOs were launched under varying conditions.Measurement of oxygen uptake rate (OUR) is a very useful tool that reflects the consumption of biodegradable substrates.We investigated the response relationship of the OUR change with phosphate concentration,the concentration of exogenous COD,pH,and the oxidation of PHAs.When phosphate was absent,the system still presented oxygen utilization.Intracellular PHA of the PAOs remained aerobic oxidation without phosphorus uptake.The presence of exogenous COD changed the phosphorus uptake rate of the PAOs and led to an extension of the aerobic uptake of phosphorus process length.The initial,varying pHs led to a difference in phosphorus uptake efficiency,pH trends,and degrees of variation in the phosphorus uptake processes.Varying initial conditions resulted in different OURs.It was shown that condition monitoring of aerobic phosphorus uptake processes can be achieved by respirometry.
