[0027] Such as figure 1 As shown, the system includes a sump 1, a lift pump 2, a sludge thickening tank 3, an advection sedimentation tank 4, a decanter 5 installed at the end of the advection sedimentation tank and an automatic control system (not shown in the figure).
[0028] Raw mine water is lifted from the underground to the collection pool 1, and after being lifted by the lift pump 2, it enters the sludge thickening tank 3 for concentration pretreatment, and then enters the advection sedimentation tank 4 for further treatment, and the decanting device 5 at the end of the advection sedimentation tank 4 Skim off the supernatant water in the pool to realize the separation of supernatant water and suspended matter. The whole operation process is controlled by the automatic control part of the system according to the liquid level change in the regulating tank.
[0029] The sludge thickening tank 3 adopts a radial flow sludge thickening tank, which pretreats the raw water by...
