Published: August 2011

In this study, results of degradation of fuchsine solution are presented by using direct current (DC) atmospheric pressure air discharge plasma. The maximum absorption at 542 nm was reduced from 10.376 to 0.062 after 15 minutes plasma treatment, corresponding to the reduction of fuchsine solution concentration from 100 mg/L down to 1.419 mg/L, which indicated that the degradation efficiency is as high as 98.51%. A notable decreasing of degradation efficiency caused from the adding of sodium carbonate suggests that free radical species is a main factor accounting for the fuchsine solution degradation. The experimental results also reveal that the solution conductivity was increased with treatment time, while the solution PH was decreased, which may show that large amount of inorganic species, such as NO3- and H+, were produced. Within the current paper, it can be concluded that the DC atmospheric pressure air discharge plasma is capable of an efficient technology for the degradation of dye wastewater.

The daily concentrations of PM10 vary from 190.76 to 670.14 μg/m3, with the average concentration of 359.36 μg/m3. The concentrations of Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Fe, Cu, Zn, Mn and Pb in PM10 are determined by Energy Dispersive X-Ray Fluorescence (EDXRF). The result shows that the fifteen elements quality accounts for 17.3%~36.7% of total mass. The X-ray diffraction (XRD) results show that six minerals are identified in the atmospheric particles. They are quartz, gypsum, kaolinite, sal-ammoniac, calcite, and albite, which account for 29%, 29%, 18%, 17%, 4% and 3%, respectively. The principle component analysis (PCA) model is used for source apportionment of PM10. The research results show that there are four sources: architecture/smelting action, coal combustion/traffic action, soil dust and particular industrial action.

In order to reduce fluorine pollution, partial fluoride could be replaced by K2O in mould flux. The effects of K2O on melting temperature, viscosity, fluidity, surface tension, Al2O3 inclusion and adsorption of low fluoride content mould flux for high speed continuous casting were studied. The results showed that with the increase of K2O content, melting temperature, viscosity and surface tension of mould flux decreased obviously, and fluidity and Al2O3 inclusion adsorption increased. When basicity was 0.81, 1.03 and 1.22, the suitable content of K2O was 5%, 5% and 4% respectively, which could play an effective role. Partial fluoride could be replaced by K2O in mould flux.

Few studies have been done on temporal changes of heavy metal pollution of urban soils. Eight soil samples at the same sites were collected inKaifengCity, China, in1994and 2006. Concentrations of Pb, Cd, As and Hg in the samples was measured. The pollution change of heavy metals from 1994 to 2006, and the relations between metal pollution and some human factors were discussed. The results show that soil pollution with metals in 2006 was higher than that in 1994 with economic growth. Soils in industrial district (ID) were more strongly polluted than in the following districts: (i) cultural and educational district (CED), (ii) mixed district of resident-commerce-administration (RCD), (iii) recreational district (RD), and (iv) suburban district (SD). Cd and Hg were the dominant pollutants. Economic growth, changes of land use and land-use authority can influence soil metal pollution significantly.

Hydrogen production from molasses wastewater was investigated in continuously-stirred tank reactor (CSTR). The CSTR was operated at an hydraulic retention time (HRT) of 6 hours and the temperature at 35°C. The highest gas production of 25.39 L/d using mixed culture fermentation, corresponding to a peak hydrogen production volume of 11.39 L/d were achieved in the CSTR reactor. While the variation of chemical oxygen demand (COD) ranged from 5500 to 8000 mg/L, the soluble end product system underwent a transition of fermentation type and the reactor gave ﬂuctuating and increasing of ORP. These experimental results demonstrate that the shock-loading and micro-anaerobic circumstance are important factors for enhancing and stabilizing H2 production.

This study investigated the effects of initial pHs and temperatures to the hydrogen production ration and cell growth ofBiohydrogenbacteriumR3sp.nov.. The initial pHs were set at 4.0, 4.5, 5.0, 5.5, 6.0, 6.5 and 6.7, respectively and the temperatures were increased from 25 °C to 45 °C in regular intervals of 5 °C at 10 g/L of the initial glucose concentration. The results indicated that pH value had a noticeable effect on the cell growth and hydrogen production. The dry cell weight and hydrogen production yield got the maximum of 0.6308 g/L and 34.2 mmol/L, respectively when the initial pH was 5.5. The final pH in the culture were always kept at 3.0~4.0. Temperature is also known to affect the maximum cell growth and specific hydrogen production ration (SHPR). And they got the maximum of 0.6682 g/L and 1.0145mol H2/mol glucose, respectively when the temperature was 30 °C. It is obvious that hydrogen production and biomass will be inhibited gradually with increasing this pH and temperature or decreasing it.

It has widely been demonstrated that nitrogen (N) addition enhances plant growth and net primary productivity of terrestrial ecosystems. Moreover, N enrichment could have a profound impact on ecosystem carbon ﬂuxes, especially in the regions where N is deﬁcient. However, there is still debate on how N affects net ecosystem CO2 exchange (NEE). A ﬁeld experiment manipulating N has been conducted in Calamagrostis anagustifolia community of Sanjiang Plain marsh of northeastern China from 2009 to 2010. N was added at a rate of 5 and 10gN m -2 yr -1with NH4NO3. The results for the 2 yr showed that gross ecosystem productivity (GEP) was higher than ecosystem respiration, leading to net carbon(C)sink (measured by NEE) over the growing season in the study site. Furthermore, low nitrogen (LN) and high nitrogen (HN) addition all signiﬁcantly stimulated growing-season NEE, on average, by 22 and 36%, respectively. It’s indicated that air temperature plays a major role in regulating ecosystem net C exchange and their responses to climatic change in Sanjiang Plain of northern China. we need long-term ﬁeld studies to predict the long-term effects of N deposition on ecosystem processes.
