By investigating the sewage treatment processes of six cigarette factories owned by China Tobacco Hubei,the current situation of sewage treatment in cigarette companies was revealed,and the process flow of each company was systematically discussed.The results show that each cigarette factory adopts diversified treatment processes based on wastewater characteristics and environmental protection standards,which can be generally divided into primary,secondary and tertiary treatment.Additionally,this paper discusses the applicability and optimization direction of sewage treatment processes in various cigarette factories,aiming to provide a theoretical basis for the selection and improvement of sewage treatment processes for cigarette companies to improve the efficiency and environmental protection of sewage treatment.
