| Abstract: | The ultra high lime aluminum method was used to treat the wastewater from accelerator diphenylguanidine production.The effects of the molar ratio of calcium hydroxide and sodium metaaluminate,reaction temperature,reaction time on the sulfate removal rate were investigated.The results showed that,the sulfate removal rate could reach 97%when the molar ratio of calcium hydroxide and sodium metaaluminate was 3/1,the reaction temperature was 90℃,and the reaction time was 60 min.The reaction product ettringite could be used as hydrotalcite like material,and good economic and social benefits were achieved. |
