摘  要：
为实现对生活垃圾进行资源化处理与合理利用,研制了适用于小区的生活垃圾有机肥制造设备.设备由控制系统、机架、反应室和推进式搅拌装置组成.将生活垃圾与微生物菌剂等辅料投入进料口,搅拌装置搅拌、混合,由通风系统保持好氧条件,并自动保持微生物的适宜环境温度,以提升转化速率,处理完成后的物料由推进式搅拌器自动排出.主要对设备的反应室、推进式搅拌装置进行了结构设计,反应室容量250L,基于单片机的控制系统,实现对温度、搅拌和通风率参数自动控制.将餐厨垃圾、木屑、EM菌、熟石灰按质量比19∶2∶2∶1混合,初始含水率为49.5%,投入设备,进行了5 d的制肥试验,启动初期加热到80℃以上,维持12 h后控制在55℃,通风率为每千克有机质0.3L/min.试验结果表明,制肥设备对通风率、温度参数的自动控制较稳定,堆体第5天含水率46.9%,pH值5.94,挥发性固体相对降解率达52.1%.

摘  要：
In order to achieve the resource-based processing of OFMSW, the organic fertilizer manufacturing equipment have been developed for the treatment of domestic garbage in the plot, which consists of control system, frame, reaction chamber and propulsion stirrer. The domestic garbage and the effective microorganisms are put into the chamber through the inlet, and then mixed and stirred by a stirring device. The aerobic condition is maintained by the ventilation system,and the suitable ambient temperature of the microorganism is automatically maintained to increase the conversion rate.After the treatment is completed, the material is automatically discharged from the equipment by a propeller stirrer. The structure design of this system was carried out such as the composting reaction chamber and stirring device. The control system based on microcontroller was carried out to realize automatic control of temperature, stirring rate and ventilation rate. A experiment was conducted for 5 days by using the source materials consisting of kitchen waste, wood chips, EM bacteria and hydrated lime with the wet weight ratio of 19∶2∶2∶1. The initial moisture content was 49.5% and the ventilation rate was set to 0.3 L/(min·kg) OM. The temperature was set at 55 ℃ after raising over 80 ℃ for 12 hours.The results show that the ventilation rate and temperature are well controlled. After 5 days, the moisture content of organic waste was 46.9%, the pH value was 5.94, and the relative degradation rate of volatile solids reached 52.1%.
