【Abstract】 They will pollute environment if the pH value,SS,fluorides,sulfide in wastewater from vetriol production are overproof.Those can be treated with a process of CaO neutralize and Al 2(SO 4) 3 precipitate and filtration,and the effluent quality reached the standard.Some important factors which effects effluent quality such as the relation of F - and pH with dozes of lime and Al 2(SO 4) 3 are studied in detail.A compound treatment process is given according to the wastewater quantity and quality of a vitriol plant.更多还原
