Abstract:

Excess sludge and sludge utilization methods are described. Excess sludge utilized with microbial fuel cell technology is introduced，including utilization of excess sludge as the fuel for microbial fuel cell directly and indirectly. In the case of excess sludge utilized as the fuel for microbial fuel cell directly，the output power density，removal efficiencies of TCOD and SS are described. In the case of excess sludge was utilized as the fuel for microbial fuel cell indirectly，the supernatant fluid of microwave pretreated sludge or the volatile fatty acids（VFA）produced by sludge fermentation is used as the fuel. These methods can utilize excess sludge effectively and have broad application prospects.

摘要：

介绍了剩余污泥存在的问题与剩余污泥资源化利用方法，重点介绍以微生物燃料电池技术资源化利用剩余污泥的研究进展，包括直接利用剩余污泥与间接利用剩余污泥为燃料的微生物燃料电池技术方面的最新研究进展。直接利用剩余污泥作为微生物燃料电池的燃料，介绍了该方法的产电输出功率密度、污泥中总化学需氧量（TCOD）等的去除情况、污泥的减量效果等；间接利用剩余污泥作为燃料，包括剩余污泥微波预处理上清液作为燃料与剩余污泥发酵产生的挥发性脂肪酸（VFA）作为燃料，这些微生物燃料电池技术都能有效地资源化利用剩余污泥，同时达到污泥减量的目的，该方法具有广阔的应用前景。
