H2O2对循环半干法烟气脱硫效率的影响分析

通过循环半干法烟气脱硫技术在某热电厂130t／h机组上的应用,分析了H2O2对循环半干法烟气脱硫效率的影响。结果表明：对于循环半干法烟气脱硫,在脱硫剂中添加少量的氧化性物质H2O2,控制H2O2水溶液浓度为1％左右增湿脱硫剂,在合适的运行条件下．当Ca／S（mol／m01）=1．1左右时,可以达到90％以上的脱硫效率。     

火电厂脱硫技术浅析

随着公众对SO2污染危害的进一步认识,火电厂SO2的污染控制问题已越来越得到广泛的重视。现有火电厂多采用湿法石灰石-石膏烟气脱硫法,其脱硫效率可达95％以上。脱硫后的废水因含有多种污染因子,需经水、污泥系统处理后方可排放。

Phragmites australis and Typha orientalis in removal of pollutant in Taihu Lake, China

Two plant populations of Phragmites australis and Typha orientalis grown in gravel and sediment substrate were studied to assess their capabilities for purifying polluted water in Taihu Lake, China. The substrate displayed most significant effects on the suspended matter (P < 0.01), with the reduction of 76%-87% and 52%-63% for P. australis, and 83%-86% and 45%-62% for T. orientalis in gravel substrate and sediment substrate, respectively. Both species and substrates significantly decreased the N and P conc...     

Photocatalytic degradation of methyl orange over ITO/CdS/ZnO interface composite films

ITO/CdS/ZnO interface composite films were successfully prepared by subsequent electrodeposition of CdS and ZnO onto indium tin oxide (ITO) glass substrates. The obtained ITO/CdS/ZnO composite films were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis spectroscopy. The photocatalytic activity of ITO/CdS/ZnO composite films were investigated using methyl orange (MO) as a model organic compound under UV light irradiation. The influence of operating parameters on MO degradation including initial concentration of MO, pH value of solution, and inorganic anion species over the composite films were examined. A blue shift of absorption threshold was observed for the ITO/CdS/ZnO film in comparison with ITO/ZnO film. ITO/CdS/ZnO composite films prepared under specific conditions showed a higher photocatalytic activity than that of ITO/ZnO films. It was also found that the photocatalytic degradation of MO on the composite filing followed pseudo-first order kinetics.
