【期刊论文】Study on Electrokinetic Remediation of Cadmium Contaminated Soils
于水利, Yu Shuili, Shi Wenxin, Feng Weiming
,-0001,():
-1年11月30日
In this study, kaolinite from a lead-zinc mining district, which was spiked with cadmium, has been treated by electrokinetics to investigate effects of treatment time and applied voltage gradient. The results showed that the increased test duration had induced a higher removal rate of cadmium. Being treated for 7 days, cadmium was removed from kaolinite dramatically. It was also found that higher removal rate happened when a higher voltage gradient was applied and cadmium accumulated near the cathode because pH increased. Increase of pH near the cathode caused accumulation of cadmium. Moreover, it was observed that cation exchange membrane which was placed between kaolinite and cathode could make pH lower than the initial value and avoid the higher pH near the cathode. As a result, the high concentration accumulation of cadmium near the cathode was avoided.

Phosphorus removal performance in an aerobic/aerobic sequencing batch reactor (SBR) supplied with glucose as carbon source was investigated. It was found that there was no phosphate release concomitant with the storing of poly-β-hydroxyalkanoate (PHA) during the anaerobic phase. Whereas, glycogen was soon built up followed by rapid consumption, at the same time, glucose was depleted rapidly. Based on the analysis of different fractions of phosphorus in activated sludge, the relative ratio of organically bound phosphorus in sludge changed at the end of anaerobic and aerobic phases. The ratios were 45.3% and 51.8% respectively. This showed that the polyphosphate broke down during the anaerobic phase to supply part of energy for PHA synthesis. The reason why there was no phosphate release might be the biosorption effect of extracellular exopolymers (EPS). It was also proved by the analysis of EPS with scanning electron microscopy (SEM) combined with energy dispersive spectrometry (EDS). The phosphorus weight percentage of EPS at the end of anaerobic phase was 9.22%.

To investigate the microbial communities of phosphate-accumulating organisms (PAOs) cultivated under different carbon sources, three sequencing batch reactors were operated supplied with sewage, glucose and sodium acetate as carbon sources respectively. The results of denaturing gradient gel electrophoresis (DGGE) of polymerase chain reaction-amplified 16S rDNA fragments demonstrated that β-protebacteria, Actinomyces sp. and γ-protebacteria only exited in 1# reactor. The microbiological diversity of 1# reactor exceeded the other two ones. Flavobacterium, Bacillales, Actinomyces, Actinobacteridae and uncultured bacteria (AF527584, AF502204, AY592749, AB076862, AJ619051, AF495454 and AY133070) could be detected in the biological phosphorus removal reactors.

【期刊论文】Study of Membrane Biological Fouling Layer Characteristics by AFM, SEM and HPLC
于水利, Yu Shui-li, Zhao Fang-bo, Li Qian, Zhang Hong-jie

To investigate the relations between the characteristics of biological fouling layer and the fouling rate of membrane in membrane bioreactors used for wastewater treatment, a comprehensive study by atomic force microscopy (AFM), scanning electron microscopy (SEM) and high pressure liquid chromatography (HPLC) was carried out with comparative analysis of two fouled membranes which operated in mixed activated sludge liquor and its supernatant, respectively. The layer surface morphology was characterized with SEM and AFM. Further, to discuss the layer formation mechanism, the molecular weight distribution of soluble microbial products (SMPs) was investigated with HPLC. The results show that AFM is an appropriate technique to characterize the biological fouling layer morphology at nanometer level. AFM reveals the layer microstructure characteristics greatly relate to the fouling rate of membrane by three-dimensional images, profile analyses and roughness computations. In the mixed activated sludge liquor, the membrane with the better filterability has rougher fouling layer. The rougher fouling layer is contributed to the role of bigger microbial flocs, which can prevent the SMPs from directly attaching on the membrane surface and keep holes in the flocs overlaps.

amation. The membrane was immerged in the aerated tank and the activated sludge liquor was recycled intermittently between the stirred tank and the aerated tank. With the recycling on and off, the two tanks underwent anoxic/anaerobic/aerobic phases in space or time sequence. By a laboratory scale ICAS-MBR for domestic wastewater treatment, the variations and relations of dissolved oxygen, oxidation-reduction potential, concentration of N and P in the stirred tank were investigated and the effects of denitrification and Phosphorus release were found. During the 6 months' operation, the removal efficiencies of COD, TN, TP and NH4-N were mostly in 90%~95%, 60%~70%, 75%~90%, 95%~99%, respectively. The effluent turbidity was less than 1 NTU and the number of the bacterium was less than 100/ml.

综述了接枝共聚、共混、表面活性剂处理等高分子有机膜改性的主要方法及其研究进展。接技共聚和共混法是常用的有机膜改性方法,改性后的膜具有高通量和良好的抗污染性、稳定性以及对环境的适应性;表面活性剂法具有简单易行的优点,但改性后的膜稳定性差。指出今后的研究应针对源水及废水的不同特点,加强现场应用研究,并应加强成膜动力学和热力学等的机理研究。
