Three kinds of aeration modes were carried out in windrow, to investigate the effects of aeration modes on the co-composting of garden waste and vegetable waste. The composting parameters such as temperature, oxygen concentration, volatile organic compounds, ratio of organic carbon to total nitrogen (C/N) and oxygen concentration showed that oxygen-dependent and intermittent ventilation composting...
This paper gives a systemic and comprehensive risk analysis of WTE plant BOT projects. The risk change curves of government and project owner in different periods are analyzed. Twelve key risks which impact on WTE plant BOT projects are identified. And all these risks are classified by government, project companies or allocated between the two parts according to risk management principle. At last,...
In this study, the aerobic landfill simulation experiments were carried out for about 31 weeks. In order to found leachate quality variation character, the temperature in the reactor, leachate (pH, CODcr, BOD5, NH4+-N) were continuously monitored. Based on the data of water quality changing under aerobic condition, the characteristics (CODcr, BOD5, NH4+-N) of leachate were determined. The degradation...
