Study on Intelligent Monitoring Technology for Composting of Agricultural and Livestock Wastes
Composting is a harmless treatment process of agricultural and livestock wastes are widely used for grass-roots livestock farms. Composting temperature control is the key technical condition in composting process. In most current production process, the mechanical artificial temperature measuring devices were adopted to measure the composting temperature, which could not monitor the composting process resulting in the dumping delay. Meanwhile, the pathogenic microorganisms in compost could not be inactivated effectively. To solve this problem, an intelligent monitoring device was designed to realize the on-line monitoring of the whole process of composting. Users can query the compost temperature in real time by smart phone so as to dump in time to improve the inactivation efficiency of pathogenic microorganisms and reduce the loss of compost nutrients. The composting monitoring experiments showed that the system could monitor the composting process on-line and will have broad application in the field of livestock waste recycling.
