The invention provides a recycling method for production wastewater of a cement kiln coordinated control system (CCS) applied to the technical field of cement kiln process production. The recycling method comprises the following steps: wastewater collected by a CCS production wastewater collection component (4) is precipitated to form a clarified liquid, and when a water level of the clarified liquid is higher than a position of a high water level sensor (5), a water pump (16) of a lifting component (14) is started, and the clarified liquid is lifted and conveyed into a back-spraying component(7); and when a water level of the clarified liquid is lower than a position of a low water level sensor (6), the water pump (16) of the lifting component (14) is stopped, and the clarified liquid isno longer lifted or conveyed into the back-spraying component (7). According to the recycling method for the production wastewater of the cement kiln CCS provided by the invention, the production wastewater in the cement kiln flue gas CO2 capture and purification process can be collected and treated conveniently and reliably, at the same time, the clarified liquid formed after the treatment is introduced into a raw material mill water spraying component for reuse, so that the method solves the problem of wastewater pollution and realizes recycling of the wastewater.
