研究了利用垃圾渗滤液进行烟气脱硫并同时吹脱去除垃圾渗滤液中氨氮这一互补工艺过程,研究证实,因其较高的碱度、对酸的缓冲能力以及金属离子的催化作用,垃圾渗滤液是一种良好的二氧化硫吸收剂,其对SO2.吸收率可达90%以上,同时渗滤液中的氨氮浓度可从133mmol·L-1降低到78mmol·L-1。在确定的实验条件下研究了垃圾渗滤液pH值以及Fe2.、Mn2.的催化作用对吸收二氧化硫的影响。实验结果表明,垃圾渗滤液pH值是吸收SO2.吹脱去除氨氮、促进Fe2.、Mn2.的催化作用以及提高吸收尾液可生化性的关键因素,需要将垃圾渗滤液吸收终点的pH值控制在6.0左右;在较低pH值条件下,Fe2.、Mn2.的催化作用对于保持较高的二氧化硫去除率具有重要作用;虽然Fe2.、Mn2.的催化机理类似,但Mn2.的催化作用优于Fe2.。研究结果证实了烟气脱硫和垃圾渗滤液氨氮吹脱处理相结合的工艺的可行性和优越性。

Pulmonary function in winter time in 1,343 school children aged 10-13 years was measured in four cities located in northern and southern part of china. The results showed that FVC, FEVl, PEF, V75, V50 and V2. in children living in homes with coal stoves were decreased by 1.5-10.7% compared with children living in homes with gas or LPG stoves in Chengde and Shanghai. In contrast to this, no significant difference in pulmonary function was found in Shenyang and Wuhan. It suggested that this phenomenon was related to indoor air pollution, and partly related to passive smoking or outdoor air pollution.

Despite the intense effort expended towards obtaining a model for describing the turbulent flows of fluid, there is no model at hand that can do an adequate job. This leads us to look for a non-traditional approach to turbulence modeling. In this work we conjoin the notion of large eddy simulation with those of fuzzy sets and neural networks to describe a class of turbulent flows. In previous works we had discussed several issues concerning large eddy simulation such as filtering and averaging. Here, we discuss the use of fuzzy sets to improve the filtering procedure.
