ABSTRACT

The operation efficiency of urban sewage treatment plants directly affects the economic benefits of investment and operation units. Most sewage treatment plants are constructed in BOT mode. It is particularly necessary to discuss the input-output relationship of sewage treatment plants from the perspective of engineering economy. With the help of the application of data envelopment analysis (DEA) in efficiency evaluation, this paper selects four indicators of total project investment, annual power consumption, annual pharmaceutical cost and number of employees as input variables, and takes the reduction of chemical oxygen demand as output variable to analyze. We calculate and analyze the overall operation efficiency, the efficiency value of DEA effective units and the efficiency value of DEA ineffective units, so as to provide experience for other similar plants.
