含磷废水的处理及排放评价OA
Treatment and Discharge Evaluation of Phosphorus-Containing Wastewater
对分析化学实验"分光光度法测定水和废水中总磷"进行改进:以绿色无毒的麦饭石为载体,制备ZnFe-LDHs(层状双金属氢氧化物)改性麦饭石吸附材料,运用FTIR、XRD、SEM、EDS-mapping等手段进行表征,探索出ZnFe-LDHs改性麦饭石对磷的最优吸附处理条件,去除率大于98.4%.含磷废水经改性麦饭石吸附处理后,磷的浓度小于0.08 mg∙L-1,符合磷一级排放标准.该改进实验内容丰富,综合性强,学生在践行"绿色化学"理念中,综合研究能力和团队协作能力得到培养提升,适合推广至本科生高年级教学.
This study presents an improvement to the analytical chemistry experiment"Determination of total phosphorus in water and wastewater by spectrophotometry".Maifannite,a green and non-toxic material,was modified with ZnFe-LDHs(layered double hydroxides)to create an adsorption material.The modified Maifannite was characterized using FTIR(Fourier Transform Infrared Spectroscopy),XRD(X-ray Diffraction),SEM(Scanning Electron Microscope),and EDS-mapping(Energy Dispersive X-ray Spectroscopy Mapping).Optimal adsorption conditions for total phosphorus by ZnFe-LDHs modified Maifannite were explored,achieving a removal rate of over 98.4%.After treatment with modified Maifannite,the concentration of phosphorus in wastewater was reduced to less than 0.08 mg·L-1,meeting the first-level discharge standard for phosphorus.This enhanced experiment is rich in content,comprehensive,and cultivates students'research and teamwork abilities while practicing the concept of"green chemistry".It is suitable for extension to higher-grade undergraduate teaching.
