摘要
污水厂污泥中富集了多种来源的有机污染物,若不进行有效处置,将会严重影响生态环境和人类健康。污泥堆肥是降解污泥中有机污染物的有效途径之一,然而堆肥后有机污染物过度残留也限制了堆肥产品的后续土地利用。以多环芳烃(PAHs)、邻苯二甲酸酯(PAEs)、抗生素和抗性基因(ARGs)等典型有机污染物为对象,综述了其在好氧堆肥过程中的降解效率以及影响因素,同时分析了堆肥产物土地利用生态风险,以期为污泥的土地利用提供建议。
A broad range of organic pollutants from different origins has been detected in the sewage sludge,which will inevitably lead to a toxic effect on the environment and human health without feasible dispose methods.Sewage sludge composting is an effective method to degrade the organic pollutants.However,the excessive residues of these pollutants restrict the subsequent land application of composting products.The efficiency and influence factors of polycyclic aromatic hydrocarbons(PAHs),phthalates(PAEs),antibiotics and antibiotics resistance genes(ARGs)removal during aerobic composting were reviewed in this paper.Moreover,the ecological risk of composting products was also assessed and aimed to provide valuable suggestions for land application.
