中国城市垃圾出路问题亟待解决

中国城市垃圾出路问题亟待解决中国环境科学学会鲍强中国正处在改革开放和经济快速发展之中，各项事业都取得了显著的成就，但仍然面临着资源短缺、技术落后、人口众多、环境退化等的严峻挑战，其中工业固体废物和城市垃圾造成的污染是当前中国面临的重大环境问题之一。据...     

环境公约,还是经济契约

2005年2月16日，签署了旨在遏制全球气候变暖的《京都议定书》的141个国家和地区喜形于色，称赞它是地球的一道“生命防线”。尽管这道犹如地球的生命“平安符”，因不少发达大国的缺席而留下深深的遗憾。但可以肯定的是，这个协议的签署，确实为地球的健康加了一道长寿的“保命符”——虽然这道“符”要发挥奇效，还须世界各国能顶住接踵而来的经济和发展调整过程中的短期不适应，以及可能出现的短期经济压力。     

生物滴滤塔处理正丁醇废气的研究

实验分别采用清水吸收法和生物滴滤法处理模拟正丁醇废气,结果表明,在实验工况条件下,清水吸收的净化效率随进口浓度的增加而增加,净化效率可达99%,最佳液气比为2.1L/m3;生物滴滤塔的净化效率随着进气流量、液体流量和进气浓度的增加而降低,当进气流量<1.0m3/h时,其对降解效率的影响较小。     

Effect of leachate recycling and inoculation on the biochemical characteristics of municipal refuse in landfill bioreactors

Activity development of key groups of enzymes involved in municipal refuse decomposition was measured in laboratory landfill bioreactors with and without leachate recycling and inoculation for about 210 days.The results showed that the enzymes(amylase,protease,cellulase,lipase and pectinase)were present in fresh refuse but at low values and positively affected by leachate recycling and refuse inoculation.The total average of cellulase activity in digesters D3 operated with leachate recycling but no inoculation,D4 and D5 operated with leachate recyling and inoculation was much higher than that in digesters D1 and D2 without leachate recycling and inoculation by 88%-127%,117%-162%and 64%-98%.The total average of protease activity was higher in digester D4 than that in digesters D1,D2,D3and D5 by 63%,39%,24%and 24%,respectively,and the positive effect of leachate recycling and inoculation on protease activity of landfilled refuse mainly was at the first two months.The total average of amylase activity was higher in digesters D3,D4 and D5 than that in digesters D1 and D2 by 83%-132%,96%-148%and 81%-129%.During the early phase of incubation,the stimulatory effect of inoculation on lipase activity was measured,but refuse moisture was the main factor affecting lipase activity of landfilled refuse.The inoculation,initial and continuous inoculation of microorganisms existing in leachate,was the mainly stimulatory factor affecting pectinase activity of landfilled refuse.     

应对气候变化的能源战略与对策

气候变化是当今国际社会高度关注的全球性问题，也是能源领域的热点问题之一。全球气候变化主要是由于人类大量燃烧化石燃料所排放的二氧化碳等温室气体引起的。随着科学界对二氧化碳等温室气体排放与气候变化之间相互关系认识的深入，要求国际社会采取对策，努力限制或减少二氧化碳等温室气体排放的呼声也越来越高，气候变化问题已日益成为影响各国制定国家能源战略的重要因素。[编者按]
