摘要
为模拟污水厂脱水污泥在填埋场中的生物降解过程,进行了脱水污泥干发酵的实验研究。测量了脱水污泥在干发酵的过程中与之相关的各种参数TOC、TN、VFA等的数值变化,得出了脱水污泥在干发酵过程中TOC和TN随着时间其浓度增加的规律,为污泥的填埋稳定化提供了理论指导。
In order to simulate the biodegradation of dewatered sewage sludge in landtill several parameters include TOC,VFA,TN that related to dry fermentation course of dewatered sewage sludge were measured.By analyzing the trends,accumulation of TOC and TN were increased with time went on.Theoretical guidance to the stabilization of sludge landfill was provided.
