城市生活垃圾管理及资源化

随着社会经济的发展和城市化进程加快，城市生活垃圾的产生量急剧增加。大中城市人均日垃圾产生量约1Kg，井以每年8％．10％的速度增长。至2005年底，生活垃圾清运量1．52亿t，垃圾的集中处理率约为51％。因此城市生活垃圾的处理问题．已成为城市环境保护一个需要迫切解决问题。解决中国城市生活垃圾问题的根本办法。一是建立有效的、环境友好型的城市生活垃圾管理体系，二是实现生活垃圾的资源化。建立有效的环境友好型的生活垃圾管理体系是解决城市生活垃圾问题的基础；生活垃圾的资源化是降低生活垃圾无害化成本，节约资源的根本出路。     

Transformation of Organic Matter of the Larch Forest Soils in the Northern Taiga of Nizhne-Tungusskoe Plateau, Central Siberia

The evaluation of biospheric role of the boreal forests in the accumulation of carbon is connected with the evaluation of organic matter (OM) pool in soils. The research sites were larch forests, they are situated on Nizhne-Tungusskoe Plateau. Larch forests of feather-moss and lichen types (110 and 380 years old) were formed on 'ochric podbur' soils. Litter stocks are 3.5–4.5 kg m^{− 2} with thickness 10–25 cm. Cryomezomorphic northern taiga soils contains 38–73 t (carbon) ha^{− 1}. Pool of fast mineralized OM has average value 38.1 t (carbon) ha^{− 1}, including 20.5 and 6.4 t (Carbon) ha^{− 1} of labile compounds on surface and in the soil, and 11.2 t (carbon) ha^{− 1} of mobile OM. Microbial mass reaches 1.78–3.47 t (carbon) ha^{− 1}, its proportion is 3.6–4.9% of the total OM carbon. Zoomass of feather-moss larch forest is 0.20–0.61 * 10^{− 2}, in lichen larch forest −0.01–0.07 * 10^{− 2} t (carbon) ha^{− 1}. A pool of resistant to biological decomposition and bonded to mineral soil matrix OM is 17.7 t (carbon) ha^{− 1} and it varies from 18.6 to 29.0 in feather-moss larch forest, and from 6.4 to 17.0 t (carbon) ha^{− 1} in lichen larch forest. Two-years field experiment has been performed to determine transformation rates of various plant litter fractions and to clarify the role of soil biota in these processes. The results showed participation of all biota groups in the decomposition of plant residues caused weight loss of larch-needles and root mortmass. Isolation of organic matter from all-size invertebrate groups leads to some decrease of decomposition activity.     

己二胺有机废液在流化床中焚烧的实验研究

在实验室规模的热态流化床试验台上，进行了含5％己二胺有机废液的焚烧 实验研究，在700－900℃范围内，研究温度及空气过剩系数对NOx沿床高的变化规律，以及它们对NOx排放浓度的影响。实验结果表明，沿高度方向上NOx浓度 逐渐降低，并且存在NO2浓度大于NO浓度这一有趣现象，在900℃下氧量增加有利于密相区NO、NO2浓度的降低，说明在 有氧条件下NH2促进NOx的还原，在不同空气 过剩系数下和然相区出口NOx几乎为零 ，表明900℃是己二胺有机废液焚烧 的合适温度。

Waste minimization and its ecological evaluation A case study in printed circuit board manufacture

The printed circuit board (PCB) manufacturers face several problems regarding the waste they generate. In Austria, a detailed study for waste minimization was carried out with three PCB manufacturers and one electroplating company. In this project a lot of ecologically and economically effective options were found and implemented. The ecological evaluation of processes is still an unsolved problem. Several evaluation models are tested on selected processes of the project.     

在磁场中活性炭吸附有机物的研究

将磁化技术引入吸附过程中，考察了磁场处理对活性炭吸附苯、硝基苯、苯甲酸、氯苯和苯酚的影响．结果表明，预磁处理能使非极性物质苯和极性较小的氯苯、苯酚在活性炭上的吸附容量减小，而使极性较大的苯甲酸和有NO2基团的硝基苯的吸附容量增大．增大磁场强度能加强苯和苯甲酸的磁处理效果。
