-[36]。圖3.8CANON和ABS提取的EPS與CIP相互作用紅外光譜結(jié)論本論文研究了菌藻共生系統(tǒng)內(nèi)胞外聚合物（EPS）跟環(huán)丙沙星（CIP）的作用機(jī)制，依靠多維度實(shí)驗(yàn)進(jìn)行分析探究，得出了以下結(jié)論：就去除效果這個(gè)層面而言，菌藻共生污水處理系統(tǒng)彰顯出高效的CIP去除能力，EPS在系統(tǒng)中發(fā)揮核心功效，實(shí)驗(yàn)結(jié)果顯示，菌藻共生系統(tǒng)中的EPS可采用吸附、絡(luò)合等多種方式和環(huán)丙沙星發(fā)生相互作用，EPS的多糖、蛋白質(zhì)等成分依靠著氫鍵、靜電吸引及配位鍵等作用力，明顯帶動(dòng)了環(huán)丙沙星的去除，和單一微生物體系比，菌藻共生體系的EPS分泌量更高，這增添了對(duì)環(huán)丙沙星的協(xié)同去除能力，給抗生素污染治理帶來(lái)了新途徑。機(jī)制研究證實(shí)，EPS中的多糖、蛋白質(zhì)等物質(zhì)跟CIP分子之間存在多重相互作用，F(xiàn)TIR以及3D-EEM分析顯示，EPS中的羥基、羧基等官能團(tuán)跟CIP的羰基等發(fā)生氫鍵結(jié)合及靜電吸附作用；微生物代謝產(chǎn)生的活性基團(tuán)讓CIP出現(xiàn)部分氧化降解，二者協(xié)同配合工作，達(dá)成對(duì)CIP的有效去除。和傳統(tǒng)處理技術(shù)相比，菌藻共生污水處理系統(tǒng)跟EPS作用相耦合具有明顯優(yōu)勢(shì)，此系統(tǒng)無(wú)需額外添加碳源，用光能推動(dòng)自養(yǎng)代謝維持系統(tǒng)的運(yùn)行，既符合綠色低碳要求，又具經(jīng)濟(jì)可行性；且菌藻共生體系具有自我修復(fù)與再生的本領(lǐng)，把處理周期給延長(zhǎng)了，減少運(yùn)行開(kāi)支，在抗生素污染治理領(lǐng)域展示出不錯(cuò)的應(yīng)用潛力。參考文獻(xiàn)劉洋.微藻及其胞外聚合物對(duì)水中喹諾酮抗生素去除途徑的研究[D].西北農(nóng)林科技大學(xué),2024.張煥軍,王席席,李軼.水體中抗生素污染現(xiàn)狀及其對(duì)氮轉(zhuǎn)化過(guò)程的影響研究進(jìn)展[J].環(huán)境化學(xué),2022,41(4):1168-1181.CaoDQ,YangWY,WangZ,etal.Roleofextracellularpolymericsubstanceinadsorptionofquinoloneantibioticsbymicrobialcellsinexcesssludge[J].ChemicalEngineeringJournal,2019,370:684-694.蔡意祥.環(huán)丙沙星在厭氧和好氧活性污泥上的吸附降解研究[D].湖南農(nóng)業(yè)大學(xué),2017.KartalB,KuenenJG,VanLoosdrechtMCM.Sewagetreatmentwithanammox[J].Science,2010,328(5979):702-703.LacknerS,GilbertEM,VlaeminckSE,etal.Full-scalepartialnitritation/anammoxexperiences–anapplicationsurvey[J].Waterresearch,2014,55:292-303.巫小丹,阮榕生,王輝,等.菌藻共生系統(tǒng)處理廢水研究現(xiàn)狀及發(fā)展前景[J].環(huán)境工程,2014,32(3):34-37.AlavianghavaniniA,ShayestehH,BahriPA,etal.Microalgaecultivationfortreatingagriculturaleffluentandproducingvalue-addedproducts[J].ScienceofTheTotalEnvironment,2024,912:169369.張萌,曹瑞瑞,肖唐佳,等.菌藻共生系統(tǒng)去除廢水抗生素機(jī)理及相關(guān)研究進(jìn)展[J].化肥設(shè)計(jì),2025,63(01):11-14.應(yīng)璐瑤,王榮昌.菌藻共生系統(tǒng)削減抗生素類污染物的去除途徑及脅迫響應(yīng)[J].化工進(jìn)展,2023,42(1):469-479.MathaiS,VeghteD,KovarikL,etal.Opticalpropertiesofindividualtarballsinthefreetroposphere[J].Environmentalscience&technology,2023,57(44):16834-16842.ZhaoW,YouJ,YinS,etal.Extracellularpolymericsubstances-antibioticsinteractioninactivatedsludge:areview[J].EnvironmentalScienceandEcotechnology,2023,13:100212.宋悅,魏亮亮,趙慶良,等.活性污泥胞外聚合物的組成與結(jié)構(gòu)特點(diǎn)及環(huán)境行為[J].環(huán)境保護(hù)科學(xué),2017,43(2):35-40.柯楠,倪瑩瑩,何嘉淇,等.微生物胞外聚合物引起的金屬腐蝕的研究進(jìn)展[J].中國(guó)腐蝕與防護(hù)學(xué)報(bào),2023,44(2):278-294.魏東.短程硝化反硝化工藝過(guò)程控制及N2O釋放研究[D].山東大學(xué),2016.任恬.藻菌共生系統(tǒng)中胞外聚合物提取條件優(yōu)化及定量分析[D].華中農(nóng)業(yè)大學(xué),2024.袁宇杰,楊英,儲(chǔ)明,等.胞外聚合物對(duì)重金屬及抗生素吸附研究進(jìn)展[J].水處理技術(shù),2022,48(05):24-28.JiangHL,TayJH,YuL,etal.Ca2+augmentationforenhancementofaerobicallygrownmicrobialgranulesinsludgeblanketreactors[J].BiotechnologyLetters,2003,25(2):95-99.翟方帥.全程自養(yǎng)-菌藻共生生物膜系統(tǒng)構(gòu)建及脫氮除磷性能研究[D].濟(jì)南大學(xué),2024.張宏揚(yáng).基于紫外三維熒光光譜的TOC檢測(cè)關(guān)鍵技術(shù)研究[D].燕山大學(xué),2020.XuC,WeiH,MengqingF,etal.Novelinsightsintosourceapportionmentofdissolvedorganicmatterinaquiferaffectedbyanthropogenicgroundwaterrecharge:Applicabilityofend-membermixinganalysisbasedopticalindices[J].TheScienceofthetotalenvironment,2022,863160885-160885.陳唐冬.傅里葉變換紅外光譜(FTIR)技術(shù)在鑒別低溫致死小鼠中的應(yīng)用研究[D].中國(guó)人民解放軍空軍軍醫(yī)大學(xué),2024.ChenW,WesterhoffP,LeenheerJA,etal.Fluorescenceexcitation?emissionmatrixregionalintegrationtoquantifyspectrafordissolvedorganicmatter[J].Environmentalscience&technology,2003,37(24):5701-5710.ShengG,YuH.Characterizationofextracellularpolymericsubstancesofaerobicandanaerobicsludgeusingthree-dimensionalexcitationandemissionmatrixfluorescencespectroscopy[J].WaterResearch,2006,40(6):1233-1239.AdavSS,LeeDJ.Extractionofextracellularpolymericsubstancesfromaerobicgranulewithcompactinteriorstructure[J].Journalofhazardousmaterials,2008,154(1-3):1120-1126.YamashitaY,TanoueE.Chemicalcharacterizationofprotein-likefluorophoresinDOMinrelationtoaromaticaminoacids[J].MarineChemistry,2003,82(3-4):255-271.BakerA,InverarityR.Protein‐likefluorescenceintensityasapossibletoolfordeterminingriverwaterquality[J].HydrologicalProcesses,2004,18(15):2927-2945.孫雅萍.基于硫鐵礦自養(yǎng)反硝化的城鎮(zhèn)尾水溶解性有機(jī)氮去除特性研究[D].濟(jì)南大學(xué),2024.ZhangT,LuJ,MaJ,etal.FluorescencespectroscopiccharacterizationofDOMfractionsisolatedfromafilteredriverwaterafterozonationandcatalyticozonation[J].Chemosphere,2008,71(5):911-921.XuJ,ShengG,MaY,etal.Rolesofextracellularpolymericsubstances(EPS)inthemigrationandremovalofsulfamethazineinactivatedsludgesystem[J].WaterResearch,2013,47(14):5298-5306.PapadopoulouA,GreenRJ,FrazierRA.InteractionofFlavonoidswithBovineSerumAlbumin:?AFluorescenceQuenchingStudy[J].JournalofAgriculturalandFoodChemistry,2005,53(1):158-163.HuY,LiuY,XiaoX.InvestigationoftheInteractionbetweenBerberineandHumanSerumAlbumin[J].Biomacromolecules,2009,10(3):517-521.WeiD,WangB,NgoHH,etal.Roleofextracellularpolymericsubstancesinbiosorptionofdyewastewaterusingaerobicgranularsludge[J].BioresourceTechnology,2015,185:14-20.ZhangH,JiaY,Khan
