摘　　要：自热高温好氧消化工艺(ATAD)是目前处理城市污泥较为新颖的一种技术,该技术处理污泥效果好,处理成本低,处理15 d左右,基本可使污泥达到无害化的标准。对自热高温好氧消化工艺进行了介绍,并对工艺运行时污泥的挥发性有机物(VSS)、脱氢酶活性(DHA)、病原菌的灭活情况、总氮(TN)、总磷(TP)、蛋白质的变化进行监测,分析了这些指标的变化规律,以期为污泥后续资源化利用研究提供参考。Autothermal thermophilic aerobic digestion(ATAD)is a relatively new technology for treating urban sludge at present.This technology has good sludge treatment effect,low treatment cost,and can basically make sludge harmless after about 15 days of treatment.This paper introduced the ATAD process,and monitored the changes of volatile organic compounds(VSS),dehydrogenase activity(DHA),pathogen inactivation,total nitrogen(TN),total phosphorus(TP),and protein of sludge during the process operation,and analyzed the change rule of these indicators,in order to provide reference for the follow-up resource utilization research of sludge.
