The evaluation of the environmental effects made by new technology: an empirical study of urban sewage-treatment intelligent-control technology

摘要

The rapid development of new technologies has met people's growing material and cultural needs, and exerted a huge influence on environment simultaneously. People are increasingly concerned about which influences the new technologies existing and being developed can exert on environment in the future, as well as how to control these influences. In order to determine new technologies' impact on the environment, the Fuzzy Analytic Decision Making Theory is applied to build the index system about environmental effects of new technologies, and evaluate environmental effects of urban sewage-treatment intelligent-control technology. The study finds that urban sewage-treatment intelligent-control technology exerts positive effects on water environment and energy-savings, particularly on water environment; and for the other two environmental factors: the carbon-emissions and solid-waste, the negative effects are slight.
