摘要：
The present disclosure provides a waste liquid recovery system, a chemical bath deposition device and a deposition method, the waste liquid recovery system comprises a waste liquid storage tank for storing the waste liquid generated by deposition of a cadmium sulfide deposition tank; a refrigeration device for refrigerating the stored waste liquid; a filtering device for filtering the waste liquid obtained after refrigerating; and a chemical liquid storage tank for storing the filtered waste liquid. The waste liquid recovery system, the chemical bath deposition device and the deposition method provided by the present disclosure provide a chemical liquid having the same concentration as an original liquid by refrigerating and filtering the waste liquid, and then replenishing the chemical raw material, thereby greatly improving the recycling of waste liquid and reducing a production cost.
