Embodiment 1
[0026] High-efficiency inorganic environmental conditioner for deep dewatering of sludge, MgO 5%, Ca(OH) 2 45%, fly ash 30%, magnetite tailings powder 6%, Al 2 o 3 8% parts, KH 2 PO 4 6%, the cost of the conditioning agent generated according to this ratio is low, but the treatment effect of the agent is poor, the mud cake is soft, and the dehydration cycle is long.
Embodiment 2
[0028] High-efficiency inorganic environmental conditioner for deep dewatering of sludge, MgO 10%, Ca(OH ) 2 65%, fly ash 10%, magnetite tailings powder 4%, Al 2 o 3 5% parts, KH 2 PO 4 6%, the cost of the conditioner generated according to this ratio is low, and it has a skeleton with the sludge. During conditioning, the sludge is sticky, the sludge particles are small, the filtering effect is not good, and the treatment effect is slightly poor.
Embodiment 3
[0030] High-efficiency inorganic environmental conditioner for deep dewatering of sludge, MgO 40%, Ca(OH ) 2 5%, fly ash 50%, magnetite tailings powder 2%, Al 2 o 3 2% parts, KH2 PO 4 1%, the conditioner generated according to this ratio has floc formation under the microscope, but the structure is loose and unstable, the sedimentation is poor, and the dehydration efficiency is low, resulting in insufficient mud biscuit degree.
