Study on the Small-scale Experiment of Salt Water Concentration and Ammonia Water Absorption in Aluminum Ash Project
Aluminum ash is an inevitable solid waste in the aluminum industry,with a huge amount generated annually.Due to its presence of harmful substances such as aluminum nitride,chloride,and fluoride,it has been included in the National Hazardous Waste List.This article introduces the concentrated salt content and ammonia absorption concentration of aluminum ash reaction salt water,briefly describes the experimental design scheme,experimental equipment,and detection equipment for aluminum ash reaction,and investigates the aluminum ash salt content and nitrogen content of a certain aluminum company in Foshan.This article aims to explore the effective removal and resource utilization of aluminum nitride in aluminum ash through the methods of salt water concentration and ammonia water absorption.
