摘要
This paper explores a new compounding coagulant for decolourization, which can decolour wastewater containing soluble dyestuffs (especially reactive and acidic dyestuffs). The best prescription and condition of this decolourizing process are discussed and the mechanism is studied. Experimental results show that the treatment efficiency of decolourization is very high by using the new coagulant. Both the colour and pH of the effluent meet the required standards. The synergism of chemical and physico-chemical actions among the coagulant components has also been found. This effect determines the superiority of the new coagulant to other single component ones.
