应用缺扯好氧膜生物反应器（A／OMBR）和缺氧一好氧传统活性污泥法（A／OAS）时模拟的己内酰胺废水进行处理和比较。实验结果表明，在不同的容积负荷下，MBR的出水水质优于AS，高负荷情况下优势更为明显。在静态实验中，MBR中污泥的硝化速率明显高于AS，有机物降解速率和反硝化速率几乎相等。     

生态弹性填料及陶粒在微污染水体处理中的应用研究

生态弹性填料是一种模拟天然水草形态加工而成的新型水处理材料，近年来在污水处理中得到了广泛应用。其具有比表面积大、去除有机物容积负荷高、生物附着性好、空隙可变、不易堵塞、适应性强、操作管理简便等优点；陶粒具有较高的孔隙率及适中的密度，所有这些都有利于微生物的生长。本文采用人工湿地作为构筑物对崇明前卫生态村中心湖的水体进行处理，结果表明，经此工艺处理后的水体，CODCr、TP、TN、氨氮等指标达到或优于国家三类水质标准。并为工程实施提供了科学依据。

Mechanism of Kenaf Retting Using Aerobes

The experimental results showed that the duration of microbial retting processing of kenaf fibers by using aerobic microbe was four times shorter than that by using anaerobic microbe. The residual gum percentage, breaking strength, breaking elongation and linear density of aerobic retted kenaf bundle fibers did not show significantly difference with that of anaerobic retted kenaf bundle fibers by ANOVA-Tukey's studentized test at a = 5% except for the softness. The bioenergetic principle and the calculation of the amount of ATP produced during the decomposition processing of kenaf gums were used to explain why the retting duration in the case of using aerobic microbes was much shorter than that of using anaerobic microbes.

Microbiological Characteristics of Anaerobic Granular Sludge in Hybrid Anaerobic Baffled Reactor

Anaerobic granular sludge is of key importance for highly effective operation of hybrid anaerobic baffled reactor (HABR).An observation and analysis on the composition of anaerobic granular sludge in each separation compartment of HABR was conducted by using scanning electron microscope (SEM)and molecular biotechnology,and specific methanogenic activity(SMA) and coenzyme F420 content were determined. It was indicated that the disparity of microbial composition was significant among these separation compartments of HABR,and the HABR encouraged phase separation.The results show the understanding of microbiological characteristics of anaerobic granular sludge in HABR is helpful for cultivating granular sludge, which ensures the effective operation of the reactor.
