Let a sewage plant running smart

Out-dated technical equipment, occlusive information communication, inadequate sanitation, low management level and some irrational distribution structures in the existing sewage plants bring about lower sewage treatment efficiency and poorer water quality, thereby permanently harming human health and severely damaging the environment. With the rapid development of scientific-technological progress and the vigorous support of the entire international community, the existing sewage plants call for more and more intelligent operation and management in the future. This review for the first time proposes the novel concept of the "smart" sewage plant, and gives a through interpretation of its special functions and attributes. We envision that the future smart sewage plant will became an "ambient intelligence" in all aspects in the sewage plants.
