The invention relates to a method and a device for recycling development waste liquid, in particular relates to a process for recycling sodium carbonate from development stripping waste liquid in PCB(printed circuit board) production. The process mainly comprises the following steps: A, feeding the development waste liquid into a homogenizing tank to homogenize water quality; B, coarsely filtering the homogenized waste liquid to remove suspended matters in the waste liquid; C, feeding the coarsely filtered developing waste liquid into a ceramic nanofiltration membrane separation system, intercepting ink to form a ceramic membrane concentrated solution, and directly recycling a ceramic membrane clear solution which is a purified sodium carbonate solution into a developing process. By adopting the process provided by the invention, the recovery rate of the sodium carbonate solution is over 50 percent, the use efficiency of the sodium carbonate in the developing and demolding process isimproved, the discharge amount of the waste liquid in the developing and demolding process is reduced, and the process has great social and economic benefits.
