高磷废水培养微藻生物质强化吸汞研究开题报告

 2020-04-16 01:04  

1. 研究目的与意义(文献综述)

hg及其化合物的排放是严重的环境问题,其在食物链中有着高毒性、全球迁移性和富集性。

汞引起的各种生理毒性,如生殖障碍、智力迟钝、抗生素耐药性等疾病都得到了证实。

离子交换、絮凝、沉淀、电化学等多种先进技术解决这一问题。

2. 研究的基本内容与方案

本课题利用不同浓度的磷溶液培养同样的藻使其最终生理结构发生变化。通过对其除汞影响因素的分析,研究不同磷浓度养出的藻除汞的结合机制。

本文的研究内容主要分为两大部分,即不同磷浓度培养出的藻体的制备与藻体除汞性能及机理的研究。

第一部分通过控制变量法确定制备藻体的最佳条件。
