CONCISE STATE MODEL FOR OPERATIONAL OPTIMIZATION OF WASTEWATER TREATMENT UNIT(S)

摘要

A method for wastewater treatment that comprises receiving influent readings from sensors located along influent stream(s) of a wastewater treatment unit, effluent readings from sensors located along effluent stream(s) of the wastewater treatment unit, a feedback flow variable calculated according to a state of a feedback flow channel between an effluent output and an influent input, analyzing the influent readings and the effluent readings to extract an influent flow variable, a total nitrogen at effluent variable and a total phosphorus at effluent variable, and calculating control instructions to control the wastewater treatment unit by assigning a combination of a cost variable reflecting a treatment cost for treating the influent stream(s), a time period, the influent flow variable, the total nitrogen at effluent variable, the total phosphorus at effluent variable, and the feedback flow variable in a state space of the wastewater treatment unit.

1. A method for wastewater treatment, comprising:
receiving influent readings from a plurality of influent sensors located along at least one influent stream of a wastewater treatment unit; analyzing said influent readings to extract an influent flow variable values; receiving effluent readings from a plurality of effluent sensors located along at least one effluent stream of said wastewater treatment unit; analyzing said effluent readings to extract a total nitrogen at effluent variable value and a total phosphorus at effluent variable value; receiving a feedback flow variable value calculated according to a condition of a feedback flow channel between an effluent output and an influent input; and calculating control instructions to control said wastewater treatment unit by estimating a state in a state space of said wastewater treatment unit according to a combination of a cost variable value reflecting a treatment cost for treating said at least one influent stream, a time period, said influent flow variable value, said total nitrogen at effluent variable value, said total phosphorus at effluent variable value, and said feedback flow variable value.
