System and method for preventing water pollution by using quality classification-based draining and quality classification-based processing

A system for preventing water pollution by using quality classification-based draining and quality classification-based processing comprises a quality classification-based draining system (1) disposed in a water area of an administration region, a quality classification-based processing system (2) disposed in a downstream water area of the quality classification-based draining system (1), and a management system (3) bidirectionally connected separately to the quality classification-based draining system (1) and the quality classification-based processing system (2). Also disclosed is a method for preventing water pollution by using quality classification-based draining and quality classification-based processing. The system can automatically monitor and recognize water quality and a water quantity in real time in an online manner, perform automatic diagnosis and self-processing according to water quality and water quantity monitoring and recognition results, and then perform quality classification-based draining and quality classification-based processing.
