摘要
我国众多河流出现水体富营养化问题,导致河流水生态失衡,严重威胁水环境安全。本文提出一种利用氧氯化锆制备载锆活性炭吸附剂的新型水体除磷方法,并基于室内试验验证了该方法的可行性和高效性。研究发现载锆活性炭吸附剂对水体中磷元素的最大吸附量为2.25mg/g,对应pH值为2-3之间。载锆活性炭吸附剂的回收利用价值较高,在5%氢氧化钠溶液种脱附率可达93.15%。研究成果为解决我国河流水体富营养化问题提供了一定的指导作用。
As the rapid development of urbanization,eutrophication occurs in many rivers in China,which leads to the imbalance of river ecology and seriously threatens the safety of water environment.In this paper,a new method of phosphorus removal using zirconium oxychloride to prepare zirconium-loaded activated as adsorbent was proposed.The feasibility and efficiency of this method are verified based on laboratory experiments.It was found that the maximum adsorption capacity of zirconium-loaded activated carbon adsorbent for phosphorus in water was 2.25mg/g,corresponding pH value between 2 and 3.The results show that the recovery value of zirconium-loaded activated carbon adsorbent is high and the desorption rate can reach 93.15%in 5%sodium hydroxide solution.The research provide a certain guidance for solving the problem of river eutrophication in China.
