摘要

Ecological stabilization pilot scale experiment was conducted for wastewater sludge treatment. The study was performed over the period from June to November in 2005 and from May to November in 2006 on a bed with 80 m(2), which located in the third wastewater treatment plant, Changchun city, China. The system left spare in 2007 and 2008. The experiment investigated sludge stabilization degree from the aspects of sludge fluid state, organic matter degradation rate and microbial activity during four years ecological treatment. After two years running and two years resting, sludge moisture decreased from averaged 97% to 30.5%, getting 68.6% of removal; organic matter content decreased from 35-46% to average 10.24%, getting more than 70% of removal. Microbial activity indicated with triphenyltetrazolium chloride-dehydrogenase activity (TTC-DHA) obviously decreased with sludge stabilization time extension, which demonstrated sludge stabilization degree, i.e. longer sludge stabilization time responded to lower TTC-DHA and higher stabilization degree.
