生活垃圾复垦排矸场其渗滤水和腐熟后土壤特性的试验研究

为了考察生活垃圾复垦排矸场的渗滤水特性,对垃圾与矸石在三种不同堆置方式下重点考察了渗滤水pH值、COD、F~-、Cr~(6 )和全Hg浓度;并对腐熟后土壤中的有机质含量、容重、含水量及饱和水等进行了测定。试验研究表明,垃圾与矸石均匀混合堆置方式具有较好的效果。

城市生活垃圾热值的测定和计算

城市生活垃圾的热值高低，不仅影响能否采用焚烧技术和焚烧厂的经济效益高低，而且影响焚烧的工艺和设备的选择。本介绍常见的七种热值测定、计算方法，并以实测值为准，对其余六种方法的准确性给予评价。北京市环境卫生科学研究所推荐的数据和计算公式及门捷耶夫公式计算出的热值较接近实测值．     

法采用甲烷化处理城市垃圾

过去1 0年,法国在生活垃圾的处理方面主要采用的是填埋或是焚烧的办法。通过焚烧垃圾可产生热能或发电,然而这样做会排出温室气体污染空气,而填埋方式可能会污染附近士地。法国目前正尝试用甲烷化处理法对付有机垃圾,以使之对环境和经济来说都有益处。位于法国蒙伯利埃的瓦拉格国际工程公司开发了一种对生活垃圾进行甲烷化处理的工艺,只需3个星期,便可以将垃圾变成堆肥和沼气。该公司的商务经理贝尔特朗·伊莱尔强调说:“我们的甲烷化处理工艺特点在于能使有机物质与空气隔离,在厌氧环境中加速降解。”他说,首先,甲烷化处理需要有个内壁用水…     

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.
