Comprehensive utilization process of carbide slag slurry

The invention discloses a carbide slag slurry comprehensive utilization process, which relates to the technical field of carbide slag treatment, and comprises the following steps: recovering 2/3 depth of supernatant into a first clear water tank, carrying out filter pressing on the supernatant in the first clear water tank by a filter press, discharging first supernatant filtrate into a second sedimentation tank for sedimentation, recovering 1/1 of the first supernatant filtrate in the second sedimentation tank, and discharging the first supernatant filtrate into a second sedimentation tank for sedimentation. Carrying out deep processing on the recovered first supernatant filtrate, carrying out filter pressing on the supernatant in the second clear water tank by a filter press, and discharging the second supernatant filtrate to a second sedimentation tank for mixing and natural sedimentation; according to the method, the supernate obtained after settlement of the carbide slag slurry is subjected to different
