摘要
使用生物炭、活性炭、研磨处理的生物炭对实验室模拟淀粉废水中氨氮、磷进行吸附处理,用紫外分光光度法对实验水样中氨氮及磷进行测定,得出:在常温下25 mL的淀粉废水中加入0.02 g生物炭时对氨氮的吸附效果最佳,加入0.06 g研磨处理的生物炭时对磷的吸附效果最佳。
Ammonia nitrogen and phosphorus in laboratory simulated starch wastewater were adsorbed with biochar, activated carbon and grinding biochar;and ammonia nitrogen and phosphorus in experimental water samples were determined by ultraviolet spectrophotometry. The results showed that the adsorption effect of ammonia nitrogen was the best when 0.02 g biochar was added to starch wastewater at room temperature, and the adsorption effect of phosphorus was the best when 0.06 g biochar was added to the starch wastewater at room temperature.
