Community Waste Classification Method Based on Discriminant Analysis

摘要

In response to the "compulsory era" of garbage classification in many places across the country,the garbage classification method has become a hot topic in social conferences.In this paper,the discriminant analysis was used to quantify and discriminate the garbage by using distance discrimination,Fisher discriminant and Bayesian discriminant method,and the specific method of garbage classification was given.The article first divided the domestic garbage into 3 categories,and then selected 5 indicators of calorific value,organic matter content,degradable time,water content and heavy metal content to determine the specific garbage category of the garbage,and convert the classification of the garbage into a discriminant function.The size of the comparison was a problem.The article found that the 2 indicators of degradable time and heavy metal content were the main factors to distinguish between organic waste and hazardous waste.Through the rational classification of waste,it would reduce environmental pressure and turn waste into treasure,which is an effective boost for China’s sustainable development.
