废水特性鉴定的批量OUR法试验研究

对活性污泥法过程模型化应用的重要课题－废水特性鉴定进行了理论和试验研究，提出利用批量反应器OUR测定，进行废水有机组分鉴定试验的数据分析方法，并对取自两个城市污水处理厂的初沉后污水进行了测定。结果表明，应用批量OUR方法能够对废水中的可生物降解的有机组分，直接进行试验测定和估值；初始OUR控制技术有助于产生适宜的OUR动态响应，以方便和较为精确地进行数据分析处理。利用试验测定结果作为模型输入，比较模型模拟和实测的OUR动态，得到了较好的吻合。

Study on Characterization of Wastewater with Batch OUR Tests

Characterization of wastewater for activated sludge process modeling has been discussed based on the theoretical studies and lab-scale experiments. Batch OUR measurement was applied to fractionation of organic components in primary settled municipal wastewater. It could be concluded that the biodegradable and biologically active components in wastewater could be characterized experimentally with batch OUR measurement. The initial OUR control approach proposed in the study offers a proper control of initial loading(F/M) to produce an adequate dynamic OUR response for convenient and accurate fractionation of wastewater. Good coincidence could be achieved when the simulated OUR outputs with the characterization results as model inputs were compared with the measured OUR curves.
