中文摘要:

为探索新的制革废水处理方法,选取不同的改性方法对粉煤灰进行改性,通过实验分析各种改性粉煤灰吸附和催化性能的优劣.实验结果表明:酸法改性粉煤灰的催化性能最好,可有效提高粉煤灰的吸附作用和催化性能;通过实验得出最佳改性条件为:酸激活剂的酸配比硫酸与盐酸体积比为1:2,10 g粉煤灰中加入15 mL的酸激活剂,在室温下进行搅拌,搅拌时间为60min,CODcr和色度的去除率都在95%以上.可为制革废水处理的实际应用提供理论指导.

英文摘要:

Aimed at probing a new tannery wastewater treatment process,the paper modified flyash by different methods and analyzed various modified flyash adsorption and catalytic performances.Experiment results showed: Catalysis of the acid modified flyash is the best,the effect of adsorption and catalytic properties of flyash can be effectively improved.The best modified conditions through experiment: Sulfuric acid and hydrochloric acid volume ratio was 1:2,adding 15mL acid activators into 10g flyash and mixing at r...
