%X In order to implement harmless treatment of waste slurry,coagulation separation was proposed to treat waste slurry from Qianjiang River Tunnel shield.The treatment experiments with sandy mud indicate that efficient separation of the mud is achieved when the specific gravity is 1.20 g/cm3,dosage of PAM is 150 mg/L,pH is about 8.Besides,the hydraulic condition could be determined under mix intensity of 300 r/min in 1min then change to 80 r/min in 20 min.The treatment experiments with clay mud indicate that efficient separation of the mud is achieved when the specific gravity is 1.10 g/cm3,dosage of PAM is 150 mg/L,pH is about 6.Besides,the hydraulic condition could be determined under mix intensity of 300 r/min in 1min then change to 80 r/min in 20 min.The treatment process lays a foundation for further treatment of waste slurry.
