Zinc smelting control method based on acid zinc online monitoring

The invention provides a zinc smelting control method based on acid zinc online monitoring. The zinc smelting control method comprises the following steps that (S1) the zinc content in a purification workshop, the zinc content and the acid content in an electrolysis workshop and the zinc content and the acid content in a waste liquid tank are obtained; (S2) judging whether the zinc content Az is within a first range or not; entering the step (S3) or (S4) according to the result; (S3) judging whether the zinc content and the acid content are in a normal range or not; determining countermeasures according to the results; (S4) judging whether the zinc content is within a second range or a third range; entering step (S5) or (S6) according to the result; (S5) judging whether the zinc content and the acid content are in a normal range or not; entering step (S7) or taking corresponding measures according to the result; (S6) judging whether the zinc content and the acid content are in a normal range or not; and (S7)
