Differential intelligent charging management method and system for chemical industry park

The invention relates to the field of chemical industry park sewage charging and management, in particular to a chemical industry park differential intelligent charging management method and system.The chemical industry park differential intelligent charging management method comprises the following steps that S1, real-time numerical values of all pollution factors in sewage of all enterprises in a chemical industry park are obtained, the flow rate of sewage discharged by each enterprise is measured; s2, for the sewage of any enterprise, calculating the proportion of the real-time numerical value of each pollution factor relative to the reference value, adjusting the standard charge according to the proportion of the pollution factor with the highest proportion, and checking the real-time charge unit price of the enterprise; s3, the real-time charging unit price of one enterprise is multiplied by the sewage flow rate of the enterprise, the price of the enterprise in unit time is obtained, and the total chargi
