Embodiment 1
[0040] The flow rate of the waste slag of a stone company is 1 ton / hour, and the mass fraction of solid particles in the waste liquid is 48%. Relying on the FLUENT software (Mixture model and standard κ-ε floc model) to simulate with the PISO algorithm, it is obtained that the stone The flow field trace, suspended solids volume fraction, flow velocity and other data of the waste residue liquid in the advection tank are simulated at the same time the concentration field and flow field distribution in the sedimentation tank, and the shape of the sedimentation tank is designed as figure 1 shown. As shown in the figure, the width of the sedimentation tank I zone changes from narrow to wide, and then gradually widens (that is, narrow-wide-narrow structure), from narrow to wide, the flow rate of waste liquid slows down. The silicon surfactant is added at a rate of 10 kg / hour, and then the narrowing of the flow channel leads to a faster flow rate of the waste liquid, which is conduci...
Embodiment 2
[0045]The flow rate of the waste slag of a stone company is 2 tons / hour, and the mass fraction of solid particles in the waste liquid is 48%. Relying on the FLUENT software (Mixture model and standard κ-ε floc model) and using the PISO algorithm to simulate, it is obtained that the stone The flow field trace, suspended solids volume fraction, flow velocity and other data of the waste residue liquid in the advection tank are simulated at the same time the concentration field and flow field distribution in the sedimentation tank, and the shape of the sedimentation tank is designed (such as figure 2 shown). At the same time, add organic silicon surfactant at the inlet of the waste residue liquid at a rate of 20 kg / hour.
[0046] The waste residue liquid passes through the sedimentation tank to complete the precipitation of large particles; and then prepares the small particle waste residue slurry with a solid content of 30% through the concentration tank.

Embodiment 3
[0049] The flow rate of the waste slag of a stone company is 5 tons / hour, and the mass fraction of solid particles in the waste liquid is 48%. Relying on the FLUENT software (Mixture model and standard κ-ε floc model) and using the PISO algorithm to simulate, it is obtained that the stone The flow field trace, suspended solids volume fraction, flow velocity and other data of the waste residue liquid in the advection tank are simulated at the same time the concentration field and flow field distribution in the sedimentation tank, and the shape of the sedimentation tank is designed. At the same time, organic silicon surfactant was added at the inlet of the waste residue liquid at a rate of 5 kg / hour.
[0050] The waste residue liquid passes through the sedimentation tank to complete the precipitation of large particles; and then prepares the small particle waste residue slurry with a solid content of 40% through the concentration tank.
[0051] The large particle calcium carbona...
