A method for industrial treatment of muck is mainly suitable for treatment of silty sand excavated during urban construction and comprises steps as follows: (1) a silty sand preliminary treatment step: treated silty sand is treated to be a loose silty sand and bulk ingredient mixture; (2) a silty sand separation step comprising (21) a coarse sand separation step and (22) a fine sand separation step; (3) a slurry treatment step: slurry overflowing a coarse sand separation tank is further subjected to fine treatment and then dewatered, and dry mud is obtained for use. A drum type silty sand separation device is adopted, the treated silty sand is treated to be the loose silty sand and bulk ingredient mixture, thus, waste mud carried by a mud truck from a construction site can be directly poured into the separation device and can be quickly treated to be the loose silty sand and bulk ingredient mixture, and accumulation cannot be caused; and besides, pottery products or porcelain products can be prepared from the treated mud according to different components of the mud, all the waste is utilized actually, the waste is turned into wealth, and the project is environment-friendly and sustainable.
