电镀废水中含有大量的重金属,成分十分复杂。它对环境和人体健康造成的危害已经引起人们极大地关注,是国内外公认的公害之一。同时电镀废水也是一种二次可再生资源。本文采用海藻生物吸附剂,以福建新文行灯饰有限公司的电镀废水为研究对象,探讨了电镀废水中重金属的回收率。 本论文对处理含Cu2+电镀废水提出了“生物吸附-解吸-中和絮凝沉淀-酸浸”的生物、化学处理工艺,并在研究的过程中具体考察了溶液的pH、搅拌时间、絮凝剂投加量等因素对Cu2+沉淀率的影响。同时,在酸浸实验中分别进行了加酸量、液固比、浸出时间对浸出效果的条件实验,结果表明这些因素会直接影响铜的回收率。 对于含Au2+电镀废水的处理,我们提出...Electroplating waste water contains large amounts of heavy metals, and its composition is very complicated. Electroplating wastewater is widely recognized one of the pollutions, and it has made great attention to people. At the same time the electroplating waste water is a kind of second renewable resource. In this paper we used the pretreated algae as the adsorbent, the electroplating waste water...学位:理学硕士院系专业:海洋与环境学院海洋学系_海洋化学学号:2242007115082
