Abstract：This paperfirstanalyzes the preparation processesof several mature filter media，including natural biofilm formation，biologicalfiltration membranes，iron-manganeseoxidecoatings，andother modified filter materials.Itthen focusesondetailing thefilmformationmethods forbiologicalfiltrationmembranesandiron-manganeseoxidecoatings，the modificationprocessesofconventional filtermedia，andtheircorresponding treatmenteficiency.Finalythemhanisms underlying the performance of different filter materials are systematically examined.

近年來，水源中的氨氮和鐵錳含量逐年增加[1]，過量的氨氮對中樞神經(jīng)系統(tǒng)有毒性作用，特別是在大腦發(fā)育過程中，可導(dǎo)致不可逆轉(zhuǎn)的損傷，引起認知障礙、癲癇和腦癱等癥狀[2]。（剩余10854字）
