含磷废水的处理及排放评价
Treatment and Discharge Evaluation of Phosphorus-Containing Wastewater
摘要
Abstract
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.关键词
