The invention discloses a refrigeration system for sewage treatment, comprising: a water inlet tank for storing a sewage concentrated solution; the precooling heat exchanger is used for precooling the sewage concentrated solution in the water inlet tank; the water pump is used for feeding the sewage concentrated solution in the water inlet tank into the crystallizing tank; the crystallizing tank is used for separating out salt in the sewage concentrated solution, precipitating and shunting; the freezing heat exchanger is used for cooling the sewage concentrated solution in the crystallizing tank; the circulating pump is used for circularly conveying the sewage concentrated solution between the crystallizing tank and the freezing heat exchanger; and the centrifugal machine is used for carrying out solid-liquid separation on the sewage concentrated solution with high salt content at the lower part of the crystallizing tank. The structure is simple, and after the modular design, transportation is more convenient
