Development and Application of Dynamic Fermentation Rotary Reactor for sewage sludge
ZHOU Yan-wen;Nanjing Research Institute of Environmental Protection;
In view of the characteristics of sewage sludge in China,the sewage plant sludge aerobic composting process were putted forward. Rotary dynamic aerobic composting device was composed by the horizontal cylinder,mixing device,aeration,ventilation equipment,condensate and leachate collecting device,a complete set of data acquisition system and control system structure.Automatic control system was made up of oxygen,temperature sensors and two controller,which connecting with aeration ventilation. It could meet the requirements of oxygen and heat dissipation. This research through the trial operation results showed that for21 d,material was heated quickly. They could keep in the high temperature stable phase( 50 ~ 60 ℃),at the end of the composting experiment,the moisture content of material fell to 44. 1%,high temperature fermentation could quickly complete sludge composting.
