A method for separating and recovering food waste, characterized in that, after removing the solid matter and the main oil slick in the food waste through a series of steps, including natural deposition and water-oil density difference, the combined minerals are treated by multi-stage air bubbles The method of ion reaction, microbial anorexia and aerobic treatment, and plant activity regulation finally makes the water reach at least the surface level IV water quality standard and then reuse or discharge it again, and the recovered solid waste is used to prepare organic fertilizers. The invention can effectively treat the organic matter, protein, and oil in the kitchen waste separation liquid, and does not use any metal substances such as aluminum salts and iron salts that are commonly used in traditional sewage treatment, ensuring the recovery and resource utilization value of the solid substances produced during the treatment process . Since the self-treated return water is used in the whole process of the invention, the use and waste of water resources are also effectively reduced.
Description
A kind of kitchen waste separation and recycling method technical field [0001] The present invention belongs to the technical field of kitchen waste treatment, in particular to a method for separating and recycling kitchen waste. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, a large amount of bottlenecks in urban development. On January 25, 2017, the National Development and Reform Commission issued the "Guidelines for Key Products and Services in Strategic Emerging Industries". Guide Catalogue (2016 edition), and the related equipment and technology research and development of "resourceless and harmless utilization of kitchen waste" are listed in the "Resources One of the sub-items of "recycling industry", which includes the aerobic fermentation of kitchen waste for resource utilization. [0003] Due to the food waste in the city, it is rich in organic matter, protein, oil, high salt and moisture....
