Resource-based disposal solutions for organic waste

In order to solve the problem of garbage siege, the organic waste in the layout of the general sanitation mainly includes kitchen waste, food waste, fruit and vegetable waste and garden greening waste. The generation points of kitchen waste, fruit and vegetable waste, and landscaping waste are relatively controllable, so the collection, transportation, and disposal of these three types of waste have established a fixed mode. At present, there is no fixed form of kitchen waste treatment mode in China. The main reason is that the promotion of garbage classification policies is different in different regions, and the quality of kitchen waste also shows great differences. Based on the difference in the composition of kitchen waste, its treatment process is also different. Low quality kitchen waste has a high similarity with mixed domestic waste, and the requirements for the capacity of the mechanical pre-treatment system are also increasing. High quality kitchen waste is currently limited by the volume, and it is difficult to improve the economic benefits of kitchen waste treatment plants without high subsidies. Due to the fact that organic waste is perishable and odorous, there are generally complex processes and difficult on-site environmental control in domestic organic waste treatment processes. Based on the composition of organic waste in China and European treatment processes, we carry out mechanical crushing, mechanical screening and other pre-treatment treatments for organic waste, followed by anaerobic, composting and other biological treatments. At the same time, the end relies on incineration for coordinated treatment to achieve resource utilization Harmless treatment.
