Abstract

The invention discloses a method for treating kitchen waste into fertilizers, and belongs to the resource utilization field of the environmental biotechnology of solid waste. The method for treating kitchen waste into fertilizers comprises the following steps: (1) sorting; (2) crushing; (3) mixing; (4) sub-packaging and sterilizing; and (6) composting at a high temperature, wherein the kitchen waste is treated by mixing crop straws, and planting oyster mushrooms, pleurotus cornucopiae and agrocybe cylindracea after sterilizing, mushrooms are picked for 2-3 times, and a proper amount of pig manure and cow dung is added to perform compost treatment after polluted fungous materials and edible fungi residues are mixed, so that resource utilization and innocent treatment of the kitchen waste are realized, environmental pollution is avoided, and great economic benefits are generated.

Description

technical field [0001] The invention belongs to the field of environmental biotechnology resource utilization of solid waste, and in particular relates to a method for fertilizing kitchen waste. Background technique [0002] Kitchen waste is the most important type of food waste, including food processing waste and food residues generated by families, schools, canteens and catering industries. Its composition is complex, mainly a mixture of oil, water, fruit peel, vegetables, rice noodles, fish, meat, bones, plastic bags, paper towels and other substances. The amount of kitchen waste in my country is huge, and it is showing a rapid upward trend. Relevant statistics show that Chinese cities produce more than 60 million tons of food every year. [0003] Kitchen waste has a significant duality of hazards and resources, and its main characteristics are: (1) High moisture content, up to 80% to 95%. (2) The salt content is high. (3) The content of organic matter is high, conta...
