Technology products are changing with each passing day, and the process of producing these products re-quires many organic solutions that can seriously pollute water resources. Therefore, the introduction of reverse logistics management in the waste liquid recycling industry is an important issue. Domestic companies face many management problems when they enter the waste recycling industry. It is important to choose key factors for efficient management. This study first explores and establishes the management factors related to the waste solution recycling industry through literature review and expert opinions and experience, and then constructs and establishes the management factors of the waste solution recycling industry through DEMATEL-based ANP (DANP). Research results show that the criteria of "momentum in dealing liquid waste", "environmental policies and regulations ", "amount of waste", "equipment cost" and "secondary pollution " are revealed to be the signifi-cant criteria of management in the wastewater treatment industry.
