【摘要】 根据国内外研究资料，综述了城市污泥在堆肥处理过程中氯代酚 (CPs)、 PCDD/Fs、多环芳烃 (PAHs)类、氯苯类 (PCBs、 CBs)等有机污染物的变化，提出将城市污泥进行堆肥处理 ,可以不同程度降解其中各种有机污染物 ,达到农用的目的。有机污染物降解的效果与其种类和性质、污泥的性质、环境因素 (包括微生物类型和数量、 C/N比、水分含量、温度、通气状况 )等有关。更多还原

【Abstract】 Land application of municipal sludge is the most attractive disposal way. However, as the sludge may contain heavy metals, parasite, pathogen, organic pollutants, especially polychlorinated dibenzo－ p－ dioxins and－ furans (PCDD/Fs), polychlorinated biphenyl (PCBs), polyaromatic hydrocarbon (PAHs), chlorophenols (CPs) and chlorobenzenes (CBs), etc, the treatment of municipal sludge on land may cause scare. The present investigation illustrates that some organic pollutants can be degraded and transformed by microorganism during composting. Their degradation was affected by their characteristics, properties of sewage sludge, environment factors, including the type and quantity of microorganism, carbon to nitrogen ratio(C/N), moisture content, temperature and air.更多还原
