AbstractAbstract Abstract Abstract In recent years，with the popularity of urban sewage treatment and increasing amour of sludge treatment，adopting mechanized and high-efficient reactor for rapid composting has become the research hotspot due to its high compost e瓶ciency as well as easy controlling．The research group has been committed to sludge resource utilization of - sludge as a resource lbr many years，in our research we have creatively brought forward I the idea of doing aging experiments with degradable and composting．To achieve this goal，we design a suit of new reactor system which can both carry on both solid waste stabilization and materiaI aging so as to study the effect of waste water and sludge aerobic and anaerobic composting after adding PASS and we did primary research on the composting mfiterials aging test under the condition of being able to compost． This research used the sewage sludge from FuZhou Xiang ban waster water treatment plant to carry out the following research： First，we design a suit of new reactor system which can both carry on both solid waste stabilization and material aging．Beginning with the sludge characteristics，we demonstrate the design，calculating process and painting for following things in detail： system of the main reaction tank，insulation and controlling temperature，churning system， air-circulation and oxygen controlling system，supporting system of the material accelerating aging．Among them，the most creative point is the trinity unique temperature controlling and insulation system entitled “tlle trinity system of Blasting to heat．Polyurethane foaming to insulate．Temperature sensation to control”．Till now we lI；．IVC appl ied two patents of this reactor．(one is for comprehensive reactor of sludge aerobic and anaerobic composting；utility．model patent no．：ZL200920 1 38759．0：the other is for the accelerating reactor for plastic film aging in the way of sludge eomposting； patent application number no．196191． Then，we u
