Title: Research on adsorption of Fe-pillared montmorillonite for Rhodamine-B
Authors: SHEN Xiaobin
PP: 2506-2511
Abstract: To study the effect of modified Ca-montmorillonite on the adsorption of dye wastewater, two sorts of Fe-pillared-montmorillonites were prepared with ferric nitrate and ferric chloride as raw materials, respectively. X-ray diffraction (XRD) results showed that the crystal face diffraction peak plane d(001) of the two Fe-pillared-montmorillonites became wider compared to the Ca-mmt. The experiment of Rhodamine-B adsorption on montmorillonite under static condition demonstrated that the adsorption isotherms of all the samples were in accord with the isothermal adsorption equation of Langmuir, and the kinetics data for the adsorption from aqueous solutions were in good agreement with the pseudo-second-order kinetics equation. The adsorption capacities of Fe(NO3)3-mmt and FeCl3-mmt were superior to Ca-mmt and the effect of Fe(NO3)3-mmt was preferable. The rates of adsorption decreased with the increase of pH value.
Keywords: water pollution control engineering; Fe-pillared; Ca-montmorillonite; dye wastewater; adsorption
 
Title: Debugging of pharmaceutical wastewater treatment by biological contact oxidation-IVCW process
Authors: TANG Guangtao, XU Dong, HE Feng, XIA Shibing, WU Zhenbin
PP: 2500-2505
Abstract: According to the water quality, the waste water of a pharmaceutical company was treated by anaerobic hydrolysis-acidification and biological contact oxidation as enhanced pre-treatment, and integrated vertical-flow constructed wetland (IVCW) process as advanced treatment. In the combined process, bio-technology and eco-technology were well integrated. The matters which should be paid attention to were discussed from the aspects of debugging preparation, activated sludge culture and unit optimization. The debugging operation and water quality monitoring indicate that chemical oxygen demand (COD) in the effluent successfully meet integrated wastewater discharge standard (GB 8978-1996), classified as the second category of pollutants of wastewater discharge A standards, after the process of biological contact oxidation and IVCW.

Title: Research on nitrogen removal of secondary effluent of wastewater treatment plant in vertical subsurface-flow constructed wetlands
Authors: CHAI Zhen, WANG Hao, ZHAO Jing, HE Xuwen
PP: 2496-2499
Abstract: By investigating the nitrogen concentrations in effluents of the vertical subsurface-flow constructed wetlands under the conditions of different hydraulic loading rates, substrates heights, and different kinds of substrates, the nitrogen removal routes in the wetlands were analyzed. It was found that the nitrogen removal routes decreased along with the increase of hydraulic loading rates. The nitrogen removal routes were lowest at the bottom of the reactor owing to the poor reoxygenation. NaCl modified zeolite made higher nitrogen removal routes.

Title: R/S-based analysis of the effect of urban development upon the climate in Fuzhou city
Authors: LIN Chenchen
PP: 2489-2495
Abstract: This paper analyzes the temperature, precipitation, relative humidity and sunshine percentage in winter and summer and their annual averages based on rescaled range analysis (R/S) analysis in Fuzhou city during recent 40 years from 1965 to 2005. The results are as follows: all the Hurst indexes in winter and summer and their annual averages are higher than 0.5 except monthly precipitation in winter, and the four climatic factors have the significant Hurst phenomena. Thus, it can be proven that such climate change in Fuzhou will be continued. The Hurst indexes of these climatic factors in summer are higher than those in winter. It can be concluded that the seasonal intensity of climatic change caused by urbanization in Fuzhou will be continued, and the temperature in winter and summer and its annual average will be continuously increased. However, there have been decreasing trends in precipitation, relative humidity, and percentage of sunshine duration in Fuzhou during recent 40 years.

Title: A reflect on environmental protection from development of farmhouse enjoyment of Ningbo city
Authors: LIN Xiongbin
PP: 2482-2488
Abstract: This paper gives a brief summary on national research of farmhouse enjoyment, also a focus on the concept and the causes of farmhouse enjoyment, which develops in the process of urbanization. As a case of study in the city of Ningbo, farmhouse enjoyment has brought considerable economic benefits, however, it remains a bad impact on the surrounding environment. Farmhouse enjoyment should play a positive role on keeping a balance of economic efficiency and environmental protection, which can be resolved through eco-environmental planning, management, optimization of facilities, process improvement and common awareness of environmental protection.

Authors: WANG Xiaonan,TIAN Jingtao,CHAI Lihe
PP: 2475-2481
Abstract: Urban system is a classic complex system. Based on Maximum Flux Principle, new ontology, epistemology and methodology are proposed in this paper. Using this principle, the new evolving model about urban system is established, which reveals the dynamics of mult-agents interaction and the evolving process of the whole structure. In the last part the application of the principle ( take Guangzhou city as the example) is introduced, which reveal that the more mature the urban development, the more generalized urban flux there is, and the bigger its structural value ξ is.

Title: Effect of pH value on the process of zero-valent iron degradation 4-Nitrochlorobenzene
Authors: WANG Lulu, LI Yan
PP: 2470-2474
Abstract: A test was conducted to examine the effect of pH value on the degradation of 4-Nitrochlorobenzene (4-ClNB) by zero-valent iron (Fe0). The results showed that, the reductive transformation rate of 4-ClNB significantly decreased with increasing pH. The lower the pH value was, the faster the degradation rate of 4-ClNB was. The initial pH value was 3 and 5, the reduction rate of 4-ClNB reached 100%; pH value was 7, the reduction rate of 4-ClNB was about 90%, while the pH value was 9 and 12, the reduction rate of 4-ClNB was only 83.7% and 33.3%. pH value change of the reduction process was detected under different pH. It was found that pH value of the reaction process gradually increased while pH value was less than 7, and pH had no significant change when pH was greater than 7. The paper analyzed the reduction process for 4-ClNB with Fe0 briefly. The final reduction product of 4-Nitrochlorobenzene was 4-Chloroaniline, no dechlorination activity.

Title: CFD numerical simulation of the pollutant proliferation in urban street canyon
Authors: HAN Jingjing, WANG Liping
PP: 2466-2469
Abstract: The pollutant proliferation in the urban street canyon was simulated in this paper applying standard k-ε model by the help of computational fluid dynamics (CFD) software Fluent. The density distribution of gaseous pollutant in the urban street canyon was analyzed under the conditions of different free flow wind speed and different line source strength. The result indicated that the clockwise gas whirlpool formed in the street canyon causes the pollutant to mostly concentrate in the street canyon leeward side, and pollutant density at the bottom of the canyon is bigger than the density at the top. The wind speed change cannot have the remarkable influence to the street valley gas flow field, but the pollutant density near ground in the canyon will reduce with the increasing wind speed. The line source strength affects the structure of the gas flow field in street canyon to a certain extent, thus causes the pollutant density distribution in the street valley changed. The research results also indicated that the simulation results of computational fluid dynamics software has practical significance to the urban atmospheric pollution problem.
