改性煤矸石处理鱼塘养殖废水的试验研究刘海成

＊刘海成1,张守花2,王现丽1,吴俊峰1(1.,　　467036;2.,　　458030)　:利用改性后的煤矸石处理鱼塘养殖废水,考察了改性煤矸石粒径、投加量、吸附时间对鱼塘养殖废水处理效果的影响。试验结果表明:在原水COD为133.1mg/L,浊度为9.8NTU,总氮12.29mg/L时,投加120目改性煤矸石1g,与50mL废水混合,振荡吸附120min,处理后出水COD为73.3mg/L,浊度为7.3NTU,总氮为0.27mg/L,对COD、浊度、总氮的去除率分别可达到44.93%,25.51%和97.8%。该项研究为改性煤矸石作为水处理吸附剂在养殖废水处理中的应用提供了理论依据,同时也为养殖废水的处理提供一种途径。将吸附氨氮及其他污染物的煤矸石应用于土壤改良,不仅可减轻氨氮对环境的污染,也为废水中氨氮的有效利用提供了一种途径。:改性煤矸石;鱼塘养殖废水;处理效果;影响因素:TD98　　　:A:1005-2763(2011)02-0079-03ExperimentalStudyontheTreatmentofFishpondAquacultureSewagewithModifiedCoalGangueLIUHaicheng1,ZHANGShouhua2,WANGXianli1,WUJunfeng1(1.HenanUniversityofUrbanConstruction,Pingdingshan,Henan467036,China;2.HebiCollegeofVocationandTechnology,Hebi,Henan458030,China)Abstract:Experimentalstudyontheinfluenceofparticlesize,dosageofmodifiedcoalgangueandadsorptiontimeuponthetreatmenteffectoffishpondaquaculturesewagebymakinguseoftheadsorptionpropertiesofmodifiedcoalgangue.TheresultsofexperimentsindicatedthatwhentheCOD,turbidityandTNofprimarywaterrespectivelywas133.1mg/L,9.8NTUand12.29mg/L,modifiedcoalgangueof120meshat1gwasaddedinto50mLwastewaterandaftervibratingadsorptionfor120min,theCOD,turbidityandTNoftreatedwaterwas73.3mg/L,7.3NTUand0.27mg/Lrespectively,theremovalefficiencyofCOD,turbidityandTNcouldreach44.93%,25.51%and97.8%respectively.Thestudyprovidedatheoreticalbasisforthemodifiedcoalgangueastheadsorbentusedintreatmentoffish-pondaquaculturesewage.Itiscanreducetheenvironmentpollu-tioncausedbyammonianitrogenandprovidesaneffectivewayfortheuseofammonianitrogeninwastewaterthatthemodifiedcoalganguewhichhasabsorbedammonianitrogenandotherpol-lutantsisusedtosoilimprovement.KeyWords:Modifiedcoalgangue,Fishpondaquaculturesew-age,Treatmenteffect,Influencingfactors0　前　言,。、。,,400hm2,1.5～2.0t/a[1,2]。,、、、[3～6]。,,。,,,。,。[7～9]。,,、。。ISSN1005-2763CN43-1215/TD　　　　　　　　　　　　　矿业研究与开发第31卷第2期MINING　RD,Vol.31,No.2　　　　　　　　　　　　　2011年4月Apr.2011＊:2010-03-30:(2008A610005).:(1973-),,,,,,Email:[e-mail]。DOI:10.13827/j.cnki.kyyk.2011.02.033,,。1　试验材料及分析检测方法(1)。—(M∶MZnCl2=2∶1,650℃,2h,)—(CHCl1.2mol/L,1h)——(105℃,1h)。(2)。,COD133.1mg/L,9.8NTU,12.05mg/L,0.235mg/L,0.006mg/L,12.29mg/L。(3)。COD,。,N-(1-)-。2　试验结果及讨论2.1　,40,60,80,100,120,180,1g50mL,2h,,COD、,。1。1　　　:,COD、,1,40120,COD10.15%44.93%,6.12%25.51%,94.9%97.8%。120180,COD44.93%47.83%,2.9%,25.51%29.59%,4.08%,97.8%98.7%,0.9%。,,120,180,,。120。2.2　1200.2,0.5,1,2,3,4,5g50mL,2h,COD、。。2。2　　　:,,2,0g1g,COD044.93%,025.51%,097.8%。1g5g,COD44.93%49.28%,25.51%39.8%,97.8%100%,,,。1g。2.3　1201g50mL,5,10,15,30,45,60,90,120,150,180min,COD、。。3。　　,,。0120min,COD044.93%,025.51%,097.8%,120min,,120min180min,COD44.93%80矿业研究与开发　　　　　　　　　　　　　　　　2011,31(2)　45.93%,25.51%27.63%,97.8%98.8%,1%,2.12%1%。120min。3　3　结　论(1)COD133.1mg/L,9.8,12.29mg/L,1201g,50mL,120min,COD73.3mg/L,7.3NTU,0.27mg/L,COD、、44.93%,25.51%97.8%。(2),。(3),,。:[1],.[J].,2006,35(2):197-200.[2]　.[J].,2006,22(3):60-62.[3]　,,.[J].,2000,6(14):71-73.[4].[J].,2003,(3):43-46.[5],.[J].,2002,(4):39-42.[6],,,.[J].,2006,26(6):60-61.[7]　.[J].,2005,25(2):43-45.[8]　,　,.NaX[J].,2000,29(5):336-340.[9],　.Y[J].,2002,25(4):29-30.　　(47)。(2),。,、、、;,。(3)。,。、,。(4)。、,,、,,,。,,,。,,。(5)、、,。:[1],　,.[J].,2007,(3):85-87.[2],,.[J].,2006,15(4):39-41.[3],,　.[J].,2007,(4):41-44.[4]　,　,.[J].,2008,10(3):60-62.[5],,.[J].,2009,(1):162-165.[6].[D].:,2004.[7]　,,.[J].,2009,(1):74-77.[8]　.[D].:,2008.[9],,.[J].,2008,17(5):45-48.81　刘海成,等:　改性煤矸石处理鱼塘养殖废水的试验研究
