With the steady development of China's economy and industry, the task of strengthening water resources protection and energy saving, industrial wastewater treatment industry in recent years has been booming. Whether government or private capital investment in industrial wastewater treatment plant, or self-built industrial wastewater treatment plant that currently prevails build affordable run can not afford to be studied for the economic evaluation of industrial waste water treatment works. Theory of life cycle cost analysis of the research status at home and abroad, can be seen as the economic evaluation of the scientific method, life cycle cost analysis method has been widely used in a variety of industries, especially in the industrial wastewater treatment industry literature search, you can see the life cycle cost analysis method applied research in industrial wastewater treatment industry is still in its infancy, the object of study for the city sewage treatment plant system, research mainly on the construction period investment estimate and running period cost analysis, the lack of a comprehensive system engineering economic evaluation methods, application life cycle cost analysis methods in the field of industrial waste water treatment works, industrial wastewater treatment project for the scientific evaluation of economic analysis tools and application examples. In this paper, based on life cycle cost theory, the characteristics of industrial wastewater, industrial wastewater engineering features and work elements were analyzed to establish the full life-cycle model of industrial waste water treatment works and the composition of each period costs were analyzed; in based on the specific circumstances of an industrial wastewater treatment projects, self-built industrial wastewater treatment plant operating mode selected enterprises to establish a life cycle cost analysis model and the calculation of the net present value method. Combined with the actual conduct of an industrial wastewater treatment works, the use of the model and the formula to calculate the life cycle cost of the project, the analysis of the cost structure of each period and put forward reasonable suggestions to control costs; technical solutions for different industrial wastewater treatment, technology to meet the requirements on the basis of biochemical treatment program life cycle cost compared to finalize the of anaerobic biochemical program for a more reasonable solution for the engineering design and project implementation, also related decision-making through risk management techniques risk and response measures to ensure the smooth progress of the project construction period and the production run of the.
