Operation optimization method for assisting wastewater commissioning of wet desulphurization system

The invention discloses an operation optimization method for assisting wastewater commissioning of a wet desulphurization system. The operation optimization method comprises the following steps: 1) constructing a wastewater treatment and discharge online operation control system calculation model; 2) obtaining the chloride ion concentration CCl<-> of a slurry in a desulfurization tower, the chloride ion concentration C1 of the desulfurization wastewater entering the desulfurization tower and the chloride ion concentration C2 of supplemented water of the desulfurization tower, and turning to step 3) when the chloride ion concentration CCl<-> of the slurry in the desulfurization tower is greater than or equal to a preset concentration value; 3) calculating the wastewater treatment flow v ofthe desulfurization tower; and 4) sending the wastewater treatment flow v of the desulfurization tower, calculated in the step 3), to an operation picture of an operator or handheld equipment of the operator, and adjusting the flow of the wastewater entering the desulfurization tower according to the wastewater treatment flow v of the desulfurization tower by the operator. The method can accurately calculate the wastewater treatment flow of the desulfurization tower, and provides data support and operation assistance for operation of the desulfurization wastewater system.
