| 摘 要： | 相对于传统活性污泥法，膜生物反应器处理生活污水具有显著的优势。通过在自行设计、加工的浸没式中空纤维微滤膜生物反应器中试装置上连续处理两种生活污水，旨在研究中空纤维微滤膜组件的性能及其影响因素，膜水通量随膜组件内真空度的变化，膜水通量随运行时间的变化和膜污染产生的原因及防治措施。了解膜生物反应器对生活污水的净化效果，出水COD、NH3-N、表色色度和浊度随运行时间的变化，膜生物反应器内污泥浓度随运行时间的变化情况等。为下一步中空纤维微滤幞生物反应器商业化应用提供基础设计数据和运行参数。

| Abstract: | An approach to analyze the period of a signal based on Hilbert-Huang transform is given. By analyzing the influence on the main-frequency distribution caused by nonlinearity of the signal, an approximate relation between the period and the main-frequency of an approximate periodic signal which contains plenty of high frequency components is established. Experiments show that one can estimate the period of a signal precisely according to its main-frequency distribution. By applying the technique to texture analysis, a novel method to extract the features of the period of a texture image is developed, which can be used in texture classification, segmentation, recognition and other applications. |
