Abstract:

A new water pollution control system which intelligently integrates the water quality and water quantity monitoring and the discharge device is proposed to replace the traditional polluted water treatment in which the water quality and quantity monitoring and discharge device were segmented into different systems. It is effective to curb water pollution spread and transport. The technical difficulties of this new system is discussed in this paper. Statistical analysis based on relevance principle proves that there are some pollutants (named multi-related pollutant) whose quantities are respectively related to several pollutant quantities simultaneously. The pollutants which can be rapidly measured on-line are selected from the multi-related pollutants, and the measurement priority is divided into different levels according to the measuring speed. The method of seeking multi-related pollutants and classifying different priority levels are expounded in this paper. Factual engineering application shows that the new system not only enables the water area to actively choose water flow according to the water quality, but also sensitively refuses unqualified water flow and therefore the paroxysmal pollution could be avoided effectively.
