酸改性活性炭在重金属与氨氮废水处理中的应用

重金属以及氨氮是造成水体污染的重要物质,在对水体重金属以及氨氮的去除方法中,活性炭吸附法有一定的进展.本文参照常见的酸类物质如硝酸、盐酸、硫酸、磷酸、柠檬酸和其他酸性物质对活性炭改性去除重金属和氨氮的研究,综述了各种酸改性的机理和对活性炭的影响,定性地比较了活性炭在各种酸改性后的去除能力.总结了对酸性改性活性炭在去除重金属和氨氮应用中的发展方向和前景,对于日后用酸性废水改性活性炭以达到以废治废的功效有着指导、借鉴作用.

Application of Acid Modified Activated Carbon on Heavy Metals and Ammonia Nitrogen Removal in Wastewater

Heavy metals and ammonia nitrogen are important chemicals that cause water pollution. Activated carbon adsorption is of great concern among all the methods that remove heavy metals and ammonia nitrogen in water body. This paper based on re- searches of heavy metals and ammonia nitrogen removal by acid modified activated carbon including nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid, citric acid and other acid, reviewed the mechanism of each acid modification and their in- fluence on activated carbon, compared the removal efficiency of all acid activated carbons qualitatively , concluded the develop- ment direction and prospects of the application of acidic modified activated carbon in removing heavy metal and ammonia nitro- gen. This paper could be used as guidance and reference for treating waste by acidic wastewater modified activated carbon in the future, to meet the purpose of treat waste with waste.
