Aluminum Clean Production Evaluation And System Development Research

As the "pollution source control" model and creative idea, Cleaner Production (CP) is widely employed. It has become more important to standardize CP and assess the efforts of CP in the enterprise. Meanwhile, as an industry with a high energy consumption and pollution, Electrolytic Aluminum enterprises need to improve the development of cleaner production seriously. So, it is significant to study on assessment and the management system for Electrolytic Aluminum Cleaner Production.Based on the principle of CP and the requirement of Cleaner Production Assessment (CPA), this paper analyzes the environmental characteristics of Electrolytic Aluminum enterprise, and builds a CPA indicator system which possesses a hierarchy and good operability and credibility. In addition, the paper discusses how to apply the method of Analytic Hierarchy Process (AHP) to confirm the weight of the indicators. The CPA indictors system shows the content and aims of CP in Electrolytic Aluminum enterprises.On the basis of theories and tools of fuzzy mathematics, the concepts of subjecting- function and subjecting-degree etc. are introduced into electrolytic Aluminum CP assessment. Through the research on the present electrolytic Aluminum industry, the standards of indicators, which are the basis of CPA, are also defined in the paper. The method can assess the present level of electrolytic Aluminum CP in the enterprises correctly.Making full use of the theories and methods above, the paper designs and develops a software system for electrolytic Aluminum CPA. During the system designing, the method of prototype is used; a database based on electrolytic Aluminum CPA indicator system is built; system developing tools such as VB, SQL are utilized in the detail design and development. The system is an effective tool for enterprises to assess the cleaner production state and improve the development of cleaner production, and for the government to carry out management of enterprise cleaner production which can be used to check, modify and renovate the indicators' information, and assess cleaner production in factory as well.At last, two typical electrolytic Aluminum enterprises are CP assessed and analyzed as examples. The results show that, the CP indicators system can reflect the state of CP of these enterprises, and the system can be used to assess, check out and so on.
