摘要
Abstract
The hazardous waste coefficient of the zinc smelting industry was calculated by the least square method in in Sichuan Province.The production process,raw and auxiliary materials,etc.of zinc smelting enterprises were investigated deeply by issuing questionnaires and on-site survey,and a one-dimensional linear model was established with product volume as the independent variable and different hazardous waste emissions as the dependent variable.The emission coefficient of hazardous waste in the zinc smelting industry was calculated using the least squares method,and the rationality and applicability of the emission coefficient were verified.The results showed that the error in the production and discharge coefficient calculated this time was relatively small,which could provide scientific basis and data support for the management of hazardous waste in zinc smelting in Sichuan Province.Meanwhile,during the accounting process,it was found that using the least squares method has computational complexity and other issues.However,this method has high accuracy and the calculated results better reflect the actual situation.Therefore,when the amount of data collected was sufficient,this method could be used to calculate the discharge coefficient.关键词
