Abstract


Through the assessment of material-selecting, advanced technology and equipment of production, improved management, fortified reusing and the process from the production to the service, Clear Production (CP) assessment assess the CP total level of the industrial and the CP level of master course of process.The Chinese industry of nitrogen fertilizer is the backbone industry of the chemical fertilizer, and is very important to the agriculture. The traditional developing model of "highly consuming of energy and resource" leads to the environment be polluted seriously in the process of the nitrogen fertilizer production. It is now difficult to carry through the abidance development of nitrogen fertilizer industry by the behindhand developing model and the strategy of pollution-control with end treatment.CP is the very important method to the development of nitrogen fertilizer industry and environmental protection. Now there are many study achievements on CP assessment home and abroad. But the CP study on the nitrogen fertilizer enterprise is infrequent. In China, the study and formulation of the technology standard and criterion on CP of nitrogen fertilizer enterprise is in initial period. The drafted CP standard is not perfect to support the CP assessment of nitrogenous fertilizer enterprise. It is significant in theory and practice to settle a series of scientific, restrict, inspiriting and concise criterion, which fits to the level of environmental management nowadays.Base on the research of CP assessment home and abroad, to settle the matter of overfull indexes and subjective assessment and so on, the paper study the CP assessment method and process, including context of assessment, maneuverable index system and objective and concise mathematics model, make certain the index value with hierarchy analysis method. Through the example CP assessment of a nitrogenous fertilizer enterprise, the paper proves the CP assessment way feasible and CP index system to be help to the CP assessment of nitrogenous fertilizer enterprise.
