Problems solved by technology

The Chinese patent discloses "kitchen waste disposal monitoring method" (application number: CN201810143498.5), which uses spectral analysis technology, provides a specific method for soil sampling, and proposes a comprehensive data processing method based on the characteristics of spectral analysis , so that the prediction effect on soil organic matter and total nitrogen content and soil metal content is basically stable and good, but it needs to separate the solid and liquid state of kitchen waste, and the detection of kitchen waste is limited to the level of elemental state
X-ray was originally used in medical imaging diagnosis and X-ray crystallography, and is now widely used in security inspection systems, but it has not been reported in the detection of kitchen waste

Abstract

The invention discloses a spectrum technology-based rapid identification method of kitchen garbage, and relates to the technical field of garbage processing. The spectrum technology-based rapid identification method comprises the three steps of sample collection, near-infrared qualitative discrimination model building and X-ray database building. By the method, a technical support is provided foridentifying classification accuracy of the kitchen garbage, and a rapid, non-destructive, accurate and environmental-friendly novel method is provided for an environmental sanitation mechanism to achieve intelligent environmental sanitation.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a method for quickly identifying kitchen waste based on spectral technology. Background technique [0002] Kitchen waste is a general term for leftover meals discarded by eating and drinking units such as families, hotels, and restaurants. At present, about 40% of the vast majority of urban waste in the world is kitchen waste, mainly including rice and flour food residues, vegetables, vegetable oils, animal oils, meat bones, fish bones, etc. Its chemical components are mainly starch, cellulose, protein, lipid and inorganic salts. Kitchen waste has the following characteristics: first, the content of organic matter such as crude protein and crude fiber is relatively high (respectively accounting for 16.73% and 2.52% of the dry matter of kitchen waste), which is of great value for development and utilization, but it is perishable and produces stench; The water content i...
